Why you should trust us

Over the past two decades, Innerbody Research has helped tens of millions of readers make more informed decisions involving staying healthy and living healthier lifestyles.

For this guide to the best greens powders, we spent 105+ hours reading up on the top contenders across the competitive landscape and poring over 70 scientific studies to narrow down our choices. Our team evaluated the products based on several key factors — like safety, cost, helpfulness, and (the ever-important) taste — to bring you information that’s paramount in deciding which greens powder is best for you.

Additionally, like all health-related content on this website, this review was thoroughly vetted by one or more members of our Medical Review Board for accuracy.

Our top considerations for greens powders

When choosing a greens powder to supplement your diet with some additional healthy nutrients, most people likely want one that’s safe, can provide benefits, doesn’t break the bank, and has good flavor to boot. So, to evaluate our top picks, we judged them based on helpfulness, safety, cost, and taste.


Winner: AG1

We chose AG1 as our winner for helpfulness based on its comprehensive formulation. It includes 75 vitamins, minerals, and whole-food sourced nutrients, with 2g of dietary fiber and plant-based protein, and well over 100% of your Daily Value of:

  • Vitamin C: 467%
  • Vitamin E: 553%
  • Thiamin (B1): 250%
  • Riboflavin (B2): 154%
  • Niacin: 125%
  • Vitamin B6: 176%
  • Folate: 170%
  • Vitamin B12: 917%
  • Biotin (B7): 1,100%
  • Zinc: 136%

And, while we’re unsure of how much of each specific ingredient is in each of AG1’s blends, the mix supplies you with decent quantities of plant-based antioxidants and adaptogens, as well as both prebiotics and probiotics.

AG1 is the only one of our top picks to provide such robust vitamin and mineral content; all of our other choices have vitamin and mineral qualities that don’t come close to half of your daily needs, let alone 100% or more. But not everyone needs that much of a boost to their diet, nor is it recommended for some people if you are taking other supplements or medications, so a greens powder with less (like our runner-up Nested Naturals) may be just enough for you.

Some greens powders also have different health focuses. For example, Bloom focuses on digestive health, while Orgain focuses more on providing organic superfoods. AG1 is really the only one of our top picks that aims to act as an “all-in-one” supplement for most of your daily vitamin and mineral needs.

However, no greens powder will provide you with the amount of dietary fiber needed to reach the recommended daily amount (14g per 1,000 calories of food consumed). The most dietary fiber in our top picks can be found in one serving of Amazing Grass at 3g. Broccoli is a common ingredient in greens powders, and eating a cup of it cooked would get you 5.2 grams of fiber, around double what most greens powders offer (about 2g). So, while greens powders can help, they aren’t a substitute for a healthy diet.


Winner: AG1

One of the most important things to keep in mind about greens powders, and dietary supplements as a whole, is that the FDA does not regulate them (they usually only step in when consumers are in danger). That's why it's essential to consider aspects like certifications, labeling, ingredients, and third-party testing. If you have food allergies or follow a special diet, you likely want the product you choose to be clear about what it does and does not contain.

Thankfully, all of our top choices for greens powders take safety seriously, with each offering a fair degree of transparency in its ingredients, allergens, organic status, testing, certifications, and vegan-friendliness. This makes it a bit tough to choose a winner for safety, but AG1 won out overall due to it being NSF Certified for Sport.

This certification ensures that AG1:

  • Is third-party tested
  • Contains what it says on the label
  • Doesn’t have unsafe levels of contaminants or any of the 290 ingredients prohibited for athletes
  • Is manufactured in a GMP-certified facility that undergoes yearly or biannual audits

The one drawback to AG1’s safety is that it does contain soy, while our other top picks are generally allergen-free. However, Amazing Grass is manufactured in a facility that uses nuts, and the flavoring in Bloom Nutrition’s coconut variety is labeled as “natural,” so it may be able to trigger allergies in some. One of our testers is sensitive to tree nuts (not allergic, though), and they didn’t experience any issues with the flavoring. Of course, everyone is different, so we always recommend speaking with your doctor before starting a new supplement, greens powders included.

Three of our top picks — Nested Naturals, Amazing Grass, and Orgain — are certified organic, and all of our choices are vegan-friendly and undergo testing to ensure product safety and quality.

In terms of the ingredients commonly found in most greens powders, there is the potential for some to interact with certain medications or medical conditions. We delve into this further under the “Are greens powders safe?” section, but, for example, spirulina, chlorella, and alfalfa can aggravate some autoimmune conditions, like lupus erythematosus.


Winner: Orgain Organic Superfoods

Cost can be an important factor when choosing a greens powder or any other “optional” product you purchase with the intent of boosting your health and well-being. If something is too expensive, you’re less likely to stick with it over time and, subsequently, less likely to see any benefit from it.

Examining our top picks, AG1 is, by far, the most expensive, with a single-purchase price of around $100, and Bloom, Nested Naturals, and Amazing Grass range from about $30-$40 for the smallest containers. When purchased from Orgain’s website, its Organic Superfoods mix also falls into that range (about $32), but if you buy from the company’s Amazon store, then the exact same tub costs only $15 for the original flavor — and, if you subscribe on Amazon, that cost drops down to only $12.74 (at the time of this writing).

It’s worth mentioning that Amazon prices fluctuate pretty regularly, but we haven’t noticed any major changes with this product. And looking through Amazon price data shows that it averages around $18, which is still a much lower cost than our other top picks.

Coming in second for cost is our overall runner-up pick, Nested Naturals Super Greens, at $29.99. Nested Naturals also boasts the best return policy of our top picks, with an “at any point in the future” money-back guarantee. Orgain’s policy, in comparison, is 30 days, but only for products purchased through its website. According to customer reviews, the company doesn’t accept returns through Amazon.


Winner: Amazing Grass Superfood Greens Blend

Known to taste grassy and earthy, greens powders are rarely marketed for their flavor, but, at the same time, the taste can make the difference between someone committing to taking a greens powder daily or giving it a pass. Two products stood out the most to us in this category: Amazing Grass Superfood Greens Blend and Nested Naturals Super Greens. The former won overall in our testers’ judgment for best-tasting unflavored greens powder, and the latter was a close second.

One of our testers compared Amazing Grass to a “watered-down and slightly less-sweet version of Naked Juice’s Green Machine.” And, surprisingly, this option is one of the only two of our top picks not to contain any form of sweetener, making its victory in this category particularly impressive. Nested Naturals contains monk fruit as a natural sweetener; it’s barely noticeable and only mellows out the “green” taste of the mix, but AG1 and Bloom contain Stevia — and it’s pretty obvious.

AG1’s Stevia aftertaste isn’t too bad, even if you aren’t a fan of sweeteners that aren’t sugar (like one of our testers), but you can definitely detect its presence. Bloom, on the other hand, contained enough Stevia to make one of our testers who regularly drinks sugar-free beverages feel it was too much.

This could’ve simply been the Bloom flavor our testers went with — coconut — as it contains 95mg of Stevia. In comparison, the original flavor of Bloom contains 57mg, which could very well be more palatable. The sweetness also isn’t as bad when mixed in juice, though it’s a bit tough to find a common juice that works with coconut besides maybe pineapple. But, for comparison, a can of a soda sweetened with only Stevia, Zevia, contains about 150mg of the natural sweetener — that’s only a 55mg difference between a soda and Bloom’s coconut greens powder.

Coming in last for taste, though, was Orgain’s Organic Superfoods + Probiotics. This was the grassiest one of the lot, according to our testers — even the hints of cinnamon in the mix weren’t enough to save it. The berry-flavored option might fare better in plain water, but our testers felt the original needs to be mixed in a smoothie or other beverage to mask the taste. (But, since taste is so subjective, it might just be your favorite one of the bunch.)

Who are greens powders for?

Mostly composed of botanicals dried at low temperatures — including fruits, leafy green vegetables, and grasses — greens powders have come a long way from the wheatgrass shots of yesteryear.

Greens powders can be a great source of whole-food-based nutrients for almost anyone who’s interested in trying them — from athletes and parents to students, people on the go, or whoever else wants to increase their daily intake of fresh fruits and vegetables. In addition to fruits and veggies, these supplemental mixes often supply vitamins, minerals, antioxidants, and, in many cases, probiotics and digestive enzymes.

For athletes who are looking to avoid the substances banned by major sports organizations, some greens powders are specifically analyzed to guarantee they’re clean. In the case of Athletic Greens’ AG1, it’s NSF Certified for Sport (which means it’s tested for those substances, among other things).

Also, there are a multitude of greens powders on the market that can fit almost any budget. While AG1 costs about $100 as a one-time purchase, our choice for best budget pick, Orgain Organic Superfoods + Probiotics, costs around $15 on the company’s Amazon store.

Who shouldn’t use greens powders?

As with any supplement, it’s a good idea to talk with your doctor before adding greens powders to your diet. But, if you take prescription medications or other supplements, it’s especially important you speak with your doctor to ensure that the greens powder you choose won’t interfere or give you too much of a certain nutrient. This is especially important if your greens powder offers more than 100% of your Daily Value of a vitamin or mineral; certain nutrients, like vitamin A or iron, among others, can potentially lead to serious side effects if you consume too much.

Children, and those who are pregnant or nursing, shouldn’t consume greens powders — the nutrient levels may be too high for children, leading to toxicity, and some plant or herbal ingredients commonly found in greens powders can affect an unborn baby or pass into breast milk.

Additionally, certain ingredients in greens powders can interact with medications or worsen medical conditions. Bromelain comes from the pineapple plant and can interact with certain medications, such as blood thinners, antibiotics, and sedatives. Some vegetables, like spinach and kale, contain vitamin K, which can also interfere with blood medications, and it should also be avoided by individuals with chronic kidney disease (CKD). We delve further into the safety concerns of greens powders in the section below.

And, finally, some greens powders can contain allergens:

  • AG1 contains soy.
  • Amazing Grass is technically allergen-free but is made in a facility that processes nuts.
  • Bloom’s coconut variety contains “natural coconut flavor” which may trigger a reaction in those who are allergic to it.

Are greens powders safe?

Most greens powders are generally safe for adults 18 and older who aren’t pregnant or breastfeeding. However, as we’ve said before, we always recommend speaking with your doctor first to make sure greens powders are a safe choice for you, especially if you have a chronic condition or take any prescription medication.

The following list notes some (but not all) potential risks or contraindications of greens powders.

  • Some common greens ingredients, like spirulina, chlorella, alfalfa, and echinacea may aggravate certain autoimmune conditions, such as lupus erythematosus, dermatomyositis, and pemphigus.
  • Supplementing with vitamins A, E, and K should be avoided by those with chronic kidney disease (CKD).
  • Ginkgo biloba and vitamin E can thin the blood, so they should be limited by those already on blood-thinning medications, like warfarin or aspirin.
  • Ashwagandha may increase the effects of benzodiazepines, such as Valium and Xanax.

With greens powders containing a wide range of ingredients (vegetables, herbs, adaptogens, and more), the above list only contains a few of the potential risks and interactions. This is why speaking with a doctor first is ideal.

Besides medications and medical conditions, there are other important details to look at when considering the safety of a dietary supplement — greens powders included. Below, we’ll look at some of the factors to keep in mind when purchasing a greens powder and how each issue might relate to you.

Food allergies

If you suffer from food allergies, intolerances, or sensitivities, you're likely adept at reading product labels for any source that may cause a reaction. And while the same scrutiny should apply to greens powders, most of our top choices are free of major allergens. However, individuals with soy allergies should know that AG1 includes it as an ingredient, Amazing Grass Greens Blend is manufactured in a facility that also processes nuts, and Bloom’s coconut variety contains “natural” coconut flavoring, which may cause a reaction.


Over-supplementation of greens powders on their own is likely rare, mainly because most of these products usually don’t contain too much of any nutrient (and they also don't typically have a flavor that compels most people to overindulge in them). However, some options, like AG1, contain 100% or more of your Daily Value of certain vitamins and minerals.

It can be dangerous to consume some nutrients in excess, such as vitamins A, D, E, and K, and certain minerals like iron and copper, which you'll find in many supplements, including some greens powders. We recommend sticking with the recommended amounts of greens powder listed on the respective container (usually one scoop). And, if you take other supplements or medications, consider reaching out to your doctor to make sure you won’t be getting too much of a vitamin or nutrient.

Caffeine and stimulants

None of our top choices for greens powders contain any significant amounts of caffeine or other stimulants, but some on the market do include these ingredients. For example, Amazing Grass, our choice for taste, also has a line of its Greens Blend that includes caffeine from yerba mate and green tea.

Organic ingredients

Among our top choices for greens powders, three are certified organic — Amazing Grass Greens Blend, Nested Naturals Super Greens, and Orgain Organic Superfoods + Probiotics. However, when examining the labeling for each product, you may see that many ingredients are organic, even if the product is not fully certified as such (this is the case with AG1).

Being certified organic means that there are no genetically modified ingredients (GMOs), and certain methods of production and handling are prohibited, like irradiation and sewage sludge.

Manufacturing methods

The manufacturing methods for greens powders are just as important as the ingredients they contain. If you've ever forgotten a bag of produce in a hot car, you know that heat degradation exists, wilting fruits and vegetables and diminishing their nutrients. The same applies to the fresh greens and grasses that make up a greens powder. Using low-temperature drying methods can help preserve nutrients.

Quality control

Quality control relates directly to customer safety. Does the company provide third-party testing for its products? Does it offer a satisfaction guarantee to its customers? Our top picks all shine in terms of quality control. However, our top pick, AG1, is NSF Certified for Sport, making it the stand-out in this regard. Our runner-up pick, Nested Naturals, comes close by having a co-packer that’s NSF Certified (but not for sport).

Greens powders vs. multivitamins

In an ideal situation, you’d obtain all of your essential nutrients from your diet, meaning that your food would cover the USDA's recommendation of:

  • 1.5-2.5 cups of fruits
  • 2-4 cups of vegetables
  • 5-7oz equivalent of protein

But even the most health-conscious among us often miss those marks in the hustle and bustle of a busy lifestyle, so supplementation may be necessary. Multivitamins and greens powders can both provide nutrients to fill in the gaps. So, how are they different, and which is better for you?

Multivitamins often include synthetic forms of vitamins and minerals, while greens powders are made from dried whole fruits, vegetables, and other botanicals. However, synthetic doesn’t necessarily mean that the nutrients in a multivitamin are somehow worse — research suggests that the bioavailability between synthetic and natural nutrients is about the same. While bioavailability is similar, there are still some minor differences. In one study on synthetic and natural vitamin B, for instance, the former didn’t demonstrate the same positive effect on oxidative stress as the latter.

Additionally, all of the greens powders featured in our top picks supply probiotics that can assist in maintaining a healthy gut, whereas you’d likely have to take an additional probiotic supplement along with your multivitamin to get the same.

With more ingredients and different processing methods, greens powders do tend to cost more than daily multivitamins. And you’ll likely have to drink your greens, while you can often just chew a multivitamin gummy or swallow a pill in a sip or two of water. (Amazing Grass does offer a greens capsule, but you’ll need to take five of those per day.)

No matter which option you ultimately choose, we recommend maintaining a healthy diet as the primary source of your daily nutrients — even when taking a multivitamin or greens powder. (If you’re interested in learning more about multivitamins, particularly those for men, you can check out our dedicated guide.)

Common ingredients in greens powders

While ingredients and ratios vary from brand to brand, greens powders commonly contain a mixture of nutritious green grasses, fruits, and vegetables; some supply additional digestive enzymes, probiotics, and herbal extracts. Below, we'll look at the science behind many common ingredients in greens powders and how they may benefit your physical well-being.


Spirulina, a blue-green microalgae, is one of the most popular ingredients in greens powders due to its rich antioxidant and nutrient profile.

While more research is needed on its potential for helping humans, spirulina may be able to help support the immune system, act as a source of protein, protect against allergic reactions, reduce oral cancer risk in those who chew tobacco, and more.


Wheatgrass is the fresh, newly sprouted leaves of the common wheat plant. It has been at the forefront of the health supplements market since it was first discovered and sold as a nutrient powerhouse in the 1930s and 40s by agricultural chemist Charles F. Schnabel.

Wheatgrass possesses antioxidant properties, phytochemicals, vitamins, and active enzymes that the body easily absorbs, offering several potential health benefits, such as free radical scavenging.

Barley grass

Barley grass is rich in gamma-aminobutyric acid (GABA), lutonarin (an antioxidant), superoxide dismutase (an enzyme), vitamins A, B1, C, and E, dietary fiber, polyphenols, and more.

Barley grass has demonstrated antidiabetic, antioxidant, anticancer, hypolipidemic, and anti-inflammatory properties in research. It may help regulate blood pressure, promote better sleep, improve digestive function, and more.


Chlorella is a type of freshwater algae with nutrients that can be difficult to absorb without proper preparation due to its hard cell wall — this is why you’ll often see “cracked cell wall” or “broken cell” or something similar beside it in the ingredients list.

Commercially available forms of this algae “contain all the vitamins required by humans.” Chlorella has also demonstrated antioxidant, antidiabetic, hepatoprotective, and immunomodulatory effects (among others) in studies.


This cruciferous vegetable can offer a multitude of benefits. It’s rich in vitamins A, C, and K, and it contains minerals like potassium, iron, and calcium. As a good source of dietary fiber, broccoli can help digestion and make you feel fuller for longer. Researchers also suggest that broccoli may help lower cholesterol, promote healthy blood pressure, improve heart function, support eye function, and boost the immune system.


Spinach is often called a “functional food,” providing vitamins A, C, and K, along with minerals like iron, potassium, and folate. Research suggests that the phytochemicals from spinach may be able to help prevent macromolecular oxidative damage, reduce inflammation, and fight cravings.

Prebiotics and probiotics

While not all greens powders contain pre- and probiotics, all of our top picks do. Prebiotics, like inulin, are indigestible and act as a food source for the microflora in your gut; they can improve the balance between good and bad bacteria.

Probiotics are live microorganisms that occur naturally in fermented foods like yogurt, kimchi, and sauerkraut. Probiotics maintain or improve the balance of gut bacteria and have shown promise for boosting immune function and digestive health. The two main genuses (or genera) of good bacteria are Lactobacillus and Bifidobacterium.

Digestive enzymes

Many greens powders include digestive enzymes among their ingredients. Astragalus, amylase, cellulase, protease, lactase, bromelain, and others can assist in digestion, helping break down proteins, carbohydrates, and lipids. These can be especially helpful for those with digestive or malabsorption disorders, like lactose intolerance.


Adaptogens refer to certain herbs, roots, and mushrooms that may help with stress relief and restoring homeostasis (they might help you “adapt” during a stressful situation). Common adaptogens included in greens powders include ashwagandha, ginseng, and astragalus. Researchers continue to study adaptogens for their potential benefits in treating stress and fatigue.


Superfoods aren’t an officially recognized type or category of foods, but they generally include natural foods that are particularly nutritious, while being low in calories. These foods are commonly associated with potentially benefiting heart health and immune system strength, as well as lowering inflammation, cholesterol, and cancer risk. Superfoods are often rich in antioxidants, vitamins, and minerals.

Some common superfoods include berries, avocados, leafy greens, cruciferous vegetables, and yogurt. Our choice for best budget pick, Orgain Organic Superfoods + Probiotics, contains 50 superfoods per serving.

Athletic Greens AG1

Best overall and most nutrients

Best Greens Powder Gg1 Mixed

  • NSF Certified for Sport
  • Vegetarian, vegan, paleo, and keto-friendly
  • Manufactured in a TGA-registered, and GMP-certified facility
  • Contains no added sugar; uses Stevia in its place
  • 75 vitamins, minerals, and whole-food sourced ingredients
  • A majority of vitamins and minerals included are near or above 100% Daily Value
  • No artificial colors, flavors, or preservatives
  • 90-day money-back guarantee


  • Contains soy, making it unsuitable for those with allergies
  • Pricier than many other greens brands
  • Precise ingredient amounts are obscured by proprietary blends
  • Has a bit of an aftertaste; one tester described it as “onion-like”
  • Requires refrigeration after opening; it’s not just suggested like other brands

AG1 from Athletic Greens is our overall winner for best greens powder. Its manufacturing standards are beyond what you normally see, and it includes 75 ingredients — much more than most competitors. AG1 provides ten vitamins and minerals above 100% of your Daily Value, with three others coming in at over 50% Daily Value.

The taste of AG1 is pretty middle-of-the-road for the greens powders our testers tried. One of our testers, who has a bit of a sensitivity to bitter tastes, noted that AG1 left a lingering “onion-like” aftertaste in the back of their mouth. But, our other testers didn’t pick up on that in their experience. They all agreed, however, that the taste of AG1’s sweetener, Stevia, is noticeable — it’s not overpowering by any means (unlike in some of Bloom’s greens), but you can taste it. If you’re not a fan of sweeteners, then our choice for best taste, Amazing Grass, could be a good alternative for you.

We cover some more details about AG1 below, but if you want an even more in-depth look at our winning greens powder, check out our full AG1 review.

Ingredients and benefits

Best Greens Powder Ag1 Ingredients

AG1 boasts a greater variety of ingredients than many of its competitors, and each daily serving provides over 100% of ten essential vitamins and minerals:

  • Vitamin C: 467%
  • Vitamin E: 553%
  • Thiamin (B1): 250%
  • Riboflavin (B2): 154%
  • Niacin: 125%
  • Vitamin B6: 176%
  • Folate: 170%
  • Vitamin B12: 917%
  • Biotin (B7): 1,100%
  • Zinc: 136%

There are also three other vitamins and minerals — vitamin A (62%), pantothenic acid (80%), and chromium (71%) — in amounts equal to more than half of your full Daily Value. None of our other top picks come close in vitamin and mineral content. But, if you’re just looking for a small boost to your nutrition, then AG1 might actually be too much. If that’s the case, then an alternative, like Nested Naturals (our runner-up pick), might be better.

AG1 is comprised of three proprietary blends and two dairy-free probiotics:

  • Raw superfood complex (7,388mg): This blend contains ingredients like spirulina, apple powder, inulin, wheatgrass juice powder, chlorella, and barley.
  • Extracts, herbs, and antioxidants (2,732mg): Some standout ingredients in this blend include pea protein isolate, citrus bioflavonoids, Rhodiola root extract, ashwagandha, and dandelion.
  • Enzyme and mushroom complex (154mg): The five ingredients in this blend are astragalus root extract, bromelain, burdock root powder, reishi mushroom powder, and shiitake mushroom powder.
  • Dairy-free probiotics (54mg): AG1 contains 7.2 billion CFU of Lactobacillus acidophilus and Bifidobacterium bifidum.

Many of the ingredients in Athletic Greens’ AG1 boast promise for boosting health. The chart below breaks down a few examples (out of many).


While it may not keep any doctors away, apple may be able to improve joint function and range of motion in older adults. The fruit might also be able to improve blood sugar levels in people with and without impaired glucose tolerance who eat some before a meal.

Citrus bioflavonoids

Flavonoids are the compounds that give plants their color and scent; they seem to possess antioxidant, anti-inflammatory, antimutagenic (protects against DNA mutations), and anticancer properties. Citrus bioflavonoids, in particular, appear to be beneficial for stress, inflammation, diabetes, and other conditions.

Burdock root

Burdock has roots in traditional medicine as a diuretic, treatment for skin concerns (like acne and eczema), and as a “blood purifier.” However, its use in greens powder is likely due to its inulin content; inulin is a dietary fiber and prebiotic that may improve digestion.


The price of AG1 is probably this greens powder’s biggest con — it’s much more expensive than any of our other top picks. A one-time purchase of AG1 is nearly $50 more than most of the competition. Even with all of the ingredients and safety precautions, $99 for a one-time purchase still feels a bit expensive to us. You can save some money, however, by subscribing to recurring deliveries; this takes 18-20% off depending on the subscription. Even with a subscription discount, AG1 is still the most expensive pick, especially considering our other top picks all have subscription discounts available, too.

The chart below breaks down the prices of various AG1 purchases.

Total cost
Cost per serving
Includes storage container and scoop
Includes shaker bottle
The Pouch; one-time purchase
The Pouch; single subscription
The Pouch; double subscription
Travel Packs; one-time purchase
Travel Packs; single subscription
Travel Packs; double subscription

Shipping from Athletic Greens in the U.S. costs a flat rate of $9. Additionally, if you aren’t a fan of your AG1, the company offers a 90-day money-back guarantee. This is the second-longest policy of our top picks — Nested Naturals takes the win here by offering an “at any point in the future” refund policy.

Nested Naturals Super Greens


Best Greens Powder Nested Naturals Mixed

  • Co-packer is NSF Certified
  • USDA certified organic
  • Third-party tested
  • Vegan-friendly, and free from common allergens and GMOs
  • A good source of vitamin C
  • Available in original and chocolate flavors
  • Offers a “100% Life-Time Satisfaction Guarantee” — return your product anytime
  • Subscribe to save 20% off recurring deliveries


  • Only available in one, 30-serving size
  • Blends obscure actual ingredient amounts
  • Vitamin content isn’t as robust as some other options

Even though some products beat it in vitamin and mineral content, Nested Naturals won our choice for runner-up due to a few standout reasons:

  • Super Greens as a product is USDA certified organic.
  • The company uses an NSF Certified co-packer (this is a bit different from AG1 being NSF Certified for Sport, but it’s still impressive).
  • The satisfaction guarantee is one of the best we’ve come across for supplements of any kind.
  • Super Greens is one of the better-tasting greens powders our testers tried.

Taste may seem like a strange addition to our reasoning for choosing Nested Naturals Super Greens as our runner-up, but if a greens powder is palatable, you’re more likely to stick to actually drinking it and seeing potential benefits. Even though it’s sweetened with monk fruit extract, you can’t tell. Unlike the Stevia in AG1 and Bloom, the monk fruit in Super Greens isn’t discernable in the least, but it does mellow out the “green” flavor. This greens powder was our testers’ second-place choice for taste, behind Amazing Grass (which, surprisingly, isn’t sweetened at all).

Ingredients and benefits

Best Greens Powder Nested Naturals Ingredients

Photo by Innerbody Research

Unlike most greens powders, Nested Naturals actually lists the amount of spirulina (667mg) and chlorella (400mg) in its Super Greens. This is far from the transparency we’d like to see from a supplement, but as far as greens powders go, something like this is better than knowing nothing but proprietary blend amounts.

Nested Naturals contains enough vitamin C (17mg, or 19% of your Daily Value) to be considered “a good source.” And, otherwise, it has:

  • Protein: 2g (4%)
  • Iron: 2mg (11%)
  • Sodium: 20mg (1%)
  • Potassium: 132mg (4%)

After evaluating AG1, it’s plain to see that Nested Naturals contains a lot less vitamin and mineral content. However, AG1 is a bit of an outlier in the greens powder space; most are closer to Nested Naturals in vitamin and mineral amounts.

Like our other top picks, Nested Naturals Super Greens is made up of blends — five all-organic blends, to be exact.

  • Alkalizing blend (3,847mg): Potentially beneficial ingredients we’ve covered previously include barley grass, wheatgrass, spirulina, chlorella, broccoli, and leafy green veggies.
  • Fiber blend (2,700mg): Apple is the most abundant ingredient in this blend, followed by rice bran and Jerusalem artichoke inulin powder. With only three ingredients in this 2,700mg blend, you’re likely getting a decent amount of these inclusions.
  • Antioxidant and immune blend (1,053mg): This blend contains ingredients like beetroot, echinacea, acai juice powder, green tea, and more.
  • Probiotic blend (333mg): Super Greens’ probiotic blend contains 1.67 billion CFU of three probiotics — Lactobacillus gasseri, Bifidobacterium bifidum, and Bifidobacterium longum.
  • Enzyme blend (67mg): The enzymes in this blend include alpha-amylase, neutral protease, lactase, lipase, and cellulase.

Interestingly, in contrast to AG1, Nested Naturals lists out the actual enzymes in the Super Greens enzyme blend; AG1 only notes the sources of the enzymes. Because of these enzymes and robust fiber blend, Nested Naturals may be particularly beneficial for digestive health.


Alpha-amylase (α-amylase) is the most abundant protein in the saliva of humans, which is why it’s also known as a salivary amylase. It plays an important role in the digestion of starches.

Neutral protease

Proteases are enzymes made in the pancreas that help break down digested proteins and generate amino acids.


If you’re lactose intolerant, then you may be intimately familiar with this enzyme. Lactase helps your body break down and properly digest the sugar found in milk products, lactose. It can help prevent or reduce bloating, diarrhea, and gas due to lactose intolerance.


Lipase helps your body break down fats, or lipids (hence the shared “lip-” prefix). Most lipase is found in your pancreas, but it can also be made in your saliva and stomach.


Cellulase enzymes help humans break down and digest the cellulose in plant cell walls and turn it into sugars (like monosaccharides).


Besides having the best satisfaction guarantee of our top picks (a 100% satisfaction guarantee where you can return products "at any time in the future"), Nested Naturals Super Greens are also competitively priced. This product is actually our next least-expensive option, right after Orgain’s Organic Superfoods (when purchased via Amazon). Additionally, you can save even more on Super Greens if you purchase the chocolate flavor.

You can also subscribe to save 20% on your Super Greens purchase and receive automatic deliveries every 30, 60, or 90 days.

The chart below breaks down the pricing for Super Greens in both original and chocolate flavors.

Super Greens original; one-time purchase$29.9930$1.00
Super Greens original; subscription (20% off)$26.9930$0.90

Orgain Organic Superfoods + Probiotics

Best budget pick

Best Greens Powder Orgain Mixed

Photo by Innerbody Research


  • Least expensive option when purchased via Amazon
  • Certified organic by the USDA
  • Kosher, vegan-friendly, and non-GMO
  • Free from gluten, soy, added sugar, sweeteners, dairy, and lactose
  • Heavy focus on superfoods; contains 50 per serving
  • Comes in original and berry flavors


  • 30-day return policy only available for direct purchases; you can’t return Amazon items
  • Original flavor tastes very grassy in plain water; testers’ least favorite
  • No amounts listed for the two included blends
  • Low price only available through Orgain’s Amazon store
  • Each tub is 20 servings instead of the usual 30 from competitors

Perhaps best known for its plant-based protein powder, Orgain also offers a small selection of superfood greens powders. Our choice for best budget pick greens powder goes, specifically, to the brand’s Organic Superfoods + Probiotics original flavor.

With over 50 organic superfoods per serving, Organic Superfoods is also the closest in ingredient amount to AG1 (which has 75 ingredients). Unfortunately, this greens powder is the least transparent of the bunch for knowing the quantity of ingredients. Like our other top picks, Orgain uses blends, but unlike those other options, this greens powder doesn’t list how much of each blend exists in the mix. With Nested Naturals, for example, you may not know how much of each inclusion is in the fiber blend, but you do know that the blend makes up 2,700mg of the mix. With Orgain’s Organic Superfoods, the trademarked blends and their inclusions are only named.

In terms of taste, the original flavor of this powder came last in our testers’ opinions; they were not fans of the overwhelmingly grassy taste, even with the obvious, spicy notes of cinnamon. However, taste is extremely subjective, and there are plenty of reviews on the Orgain website and the Amazon product page praising the taste.

Insider Tip: If you’re already a fan of Orgain’s chocolate protein powder and want to try adding the company’s greens powder to your regimen, we recommend mixing them together in a single non-dairy milk-based beverage. The chocolate covers up a lot of the green flavor, and the cinnamon compliments the chocolate nicely.


Best Greens Powder Orgain Ingredients

As mentioned above, the lack of ingredient quantity information makes it a bit difficult to know how much of each inclusion is in Orgain’s Organic Superfoods + Probiotics. And, speaking of probiotics, the company doesn’t even list how many colony-forming units (CFU) are in the blend; given that this comes dead last in the ingredient list, though, it’s probably not too many. The higher up an item is in an ingredients list, the greater the amount.

The two trademarked blends in Orgain’s Organic Superfoods + Probiotics include:

  • Orgain Organic 50 Superfoods Blend
  • Orgain Organic Super Veggies, Super Berries, Super Grasses & Super Foods Blend

Interestingly (and a bit confusingly), the “50 Superfoods Blend” doesn’t actually contain 50 ingredients — it contains 20. The other 30 are found in the second veggies, berries, and grasses blend. Perhaps the 50 Superfoods Blend actually contains the other blend, but this isn’t made abundantly clear.

For vitamin and mineral content, this greens powder has:

  • Protein: 1g (2%)
  • Vitamin D: 0mcg (0%)
  • Calcium: 20mg (2%)
  • Iron: 0.5mg (2%)
  • Potassium: 40mg (0%)

We don’t quite understand why Orgain specifically lists vitamin D content when there is none in this greens powder. If Orgain’s superfood powder offerings interest you, but you want some vitamin D, the company also sells a variety of its Organic Superfoods mix called “+ Immunity Up!” which includes 4.4mcg (20%) of the nutrient. This option is significantly more expensive, however.

Some of the fruits and vegetables included in Orgain’s 50 superfoods are:

  • Millet
  • Amaranth
  • Buckwheat
  • Quinoa
  • Chia
  • Kale powder
  • Apple pulp
  • Cinnamon
  • Sprouts
  • Acai
  • Cranberry
  • Wheatgrass
  • Barley grass
  • Oat grass
  • Beet
  • Carrot
  • Spinach
  • Garlic

Some of these ingredients are unique compared to our other top picks. Orgain is the only one to contain chia, for instance. These seeds are high in fiber and omega-3 fatty acids (ALA, specifically). According to the Mayo Clinic, the fiber content in chia seeds may lead them to help with heart health, cholesterol, and digestive health.


To get the best price for Orgain’s Organic Superfoods + Probiotics powder, you’ll have to navigate over to the company’s Amazon store. There are benefits and drawbacks to purchasing either direct or from Amazon, however. If you buy from Orgain, you can take advantage of the company’s 30-day return policy, but you won’t be able to return your purchase or get a refund from Amazon. But buying from Amazon cuts the price in half.

Here’s how the prices break down from both sites.

CostServingsCost per serving
Amazon one-time purchase$14.9920$0.75
Amazon subscription purchase (5% off)$12.7420$0.64
Orgain website one-time purchase$32.9920$1.65
Orgain website subscription purchase (25% off)$24.7420$1.24

Additionally, free shipping kicks in on the Orgain website once you’ve reached an order of $75, otherwise it’s $9.95.

Amazing Grass Superfood Greens Blend

Best-tasting unflavored greens powder

Best Greens Powder Amazing Grass Mixed

Photo by Innerbody Research


  • CCOF-certified organic (California Certified Organic Farmers)
  • Ingredients are Kosher, vegan-friendly, non-GMO, and free of common allergens
  • Three flavor options: original, chocolate, and berry
  • Original flavor was our testers’ favorite unflavored greens powder
  • No sugar or added sweetener in any flavor
  • Offers a capsule alternative
  • Comes in multiple container sizes, including individual packets


  • Made in a facility that processes nuts
  • Different flavors contain different ingredients and nutrient amounts
  • Return policy requires products be unopened
  • May not be suitable for those with FODMAP sensitivities
  • High vitamin K content may not be ideal for those with chronic kidney disease

Amazing Grass Greens Blend is our choice for best-tasting unflavored greens powder. Despite not being sweetened with sugar or natural sweeteners, this certified-organic greens powder tastes strikingly similar to a lighter, almost “watered-down” version of Naked Juice’s Green Machine (a fairly popular green juice).

Taste aside, we also appreciate how many ways you can purchase Amazing Grass. It comes in three serving quantities (30, 60, and 100), a bottle of 150 capsules, and a box of 15 single-use packets for on-the-go use.

Ingredients and benefits


Photo by Innerbody Research

While Athletic Greens AG1 offers over 70 ingredients in its powder, Amazing Grass has the least amount of ingredients of our top picks (only 27). These 27 ingredients, divided into four proprietary blends, do cover what you’d normally find in a greens powder, however.

  • Green food blend (5.7g): Ingredients include wheat grass, barley grass, alfalfa, spinach, spirulina, chlorella, and broccoli.
  • Antioxidant blend (1.1g): This blend contains rose hips, pineapple, carrot, acerola cherry, green tea, acai berry, beetroot, raspberry, and maca root.
  • EFA fiber blend (668mg): This blend contains just two ingredients — flax seed and apple pectin. We’re assuming that EFA stands for essential fatty acids in this case due to the inclusion of flax seed, a rich source of plant-based omega-3s.
  • Digestive enzyme and pre/probiotic blend (426mg): Ingredients include fructooligosaccharides, amylase, protease, lipase, lactase, cellulase, and Lactobacillus acidophilus.

In terms of nutrition facts, Amazing Grass contains the following:

  • Protein: 2g (4%)
  • Vitamin A: 60mcg (7%)
  • Vitamin C: 16mg (18%)
  • Vitamin K: 70mcg (58%)
  • Calcium: 40mg (3%)
  • Iron: 1.5mg (8%)
  • Sodium: 30mg (1%)
  • Potassium: 170mg (4%)

Greens Blend offers a nice amount of vitamin and mineral content compared to some other competitors. But, while it should be safe for most adults, there are two inclusions that could make it unsuitable for some populations.

  • The addition of fructooligosaccharides (F.O.S.) in the final blend means that some people with FODMAP sensitivities may experience digestive problems (like upset stomach, gas, bloating, and more) instead of benefits from this greens powder.
  • In people with chronic kidney disease (CKD), vitamins A, E, and K should be avoided, as they’re more likely to build up in the body and cause harm. For some patients, vitamin C should also be avoided or limited.


Amazing Grass Greens Blend is fairly middle-of-the-road when it comes to cost (for the 30-serving option, anyway). To save some money, you can take advantage of the company’s subscription option, which takes 20% off the cost of all products.

The chart below shows how the prices vary depending on the product you choose (powder, capsules, or individual packets).

Single purchase costSubscription cost (20% off)
Powder; 30 servings$39.99$31.99
Powder; 60 servings$69.99$55.99
Powder; 100 servings$99.99$79.99
Capsules; 30 servings (150 capsules)$39.99$31.99
Box of 15 individual packets$28.99$23.19

Amazing Grass also has a “Buy More, Save More” savings option; when you buy two items, you get 5% off, and purchasing more than three nets you 10% off. Shipping and handling are free for all orders over $59.99, but it costs $7.99 otherwise.

For returns — unlike AG1, Orgain, and Nested Naturals — the policy from Amazing Grass comes with the caveat that the product must be unopened.

Bloom Nutrition Greens & Superfoods

Most flavor choices

Best GreensPowder Bloom Mixed

Photo by Innerbody Research


  • Wide range of flavors, including various seasonal ones and a plain original
  • Free of most common allergens
  • Only 15 calories per serving (when mixed in water)
  • Largest pre- and probiotic blend of our picks
  • All orders in the U.S. ship for free
  • Subscribe to save 10%


  • Very sweet, with a strong Stevia taste
  • Coconut flavor may not be suitable for those with allergies
  • Ingredients are in lower quantities than most competitors
  • Not FODMAP-diet friendly

If you’ve heard of Bloom Nutrition’s Greens & Superfoods before, it was probably through social media, most likely a TikTok influencer praising the powder. However, social media influencers are paid to influence you to purchase a product, even if it doesn’t actually help them at all.

But, while Bloom’s Greens & Superfoods powder doesn’t contain nearly the amount of vitamins and minerals as our other top picks, it does have some ingredients that could help your health in one way or another.

Bloom’s greens come in two sizes (30 and 60 servings) and a variety of flavors, with some limited-time offerings, like orange passionfruit, depending on the season. Since one of the main draws of Bloom is its flavor options, our testers chose the coconut variety to try instead of the plain original one (like we purchased for our other top picks).

Unfortunately, Bloom’s use of 95mg of Stevia as its sweetener of choice makes the coconut flavor taste extremely sweet (much sweeter than AG1, which also uses Stevia). The company also uses 95mg of Stevia in its other flavors, but perhaps the citrus or berry flavors handle this sweetness better. If you’re looking for a bit less Stevia, the original flavor contains 57mg.

Although, like with our opinions on Orgain’s taste, it’s all subjective, and you could love the taste of Bloom’s greens powder more than other options on the market.

The current flavor varieties at the time of this writing include:

  • Mango
  • Strawberry kiwi
  • Berry
  • Coconut
  • Citrus
  • Orange passionfruit
  • Original (plain)


Best Greens Powder Bloom Ingredients

Out of our top picks, Bloom seems to have the least amount of vitamins and minerals. Or, at least, the company doesn’t list them on the label. The only two applicable entries are for iron (0.6mg, 3%) and sodium (5mg, less than 1%). Perhaps the ingredient amounts in the seven blends are too miniscule to add up to anything worthwhile in the supplement facts, but it still seems a bit odd. When we reached out to customer service to ask about this, they just told us that the ingredients can be viewed on the product page.

As noted above, Bloom’s greens contain seven blends (more than any of our other picks). This division of ingredients could be why it seems like there’s so little in the powder. Combining the first two blends, for instance, adds up to about the same amount as the robust fiber blend in Nested Naturals.

Also, before we delve into the blends, it’s worth mentioning that we rounded up Bloom’s blend quantities to the tenths place (the company, strangely, includes the digits down to the thousandths place). For instance, the fiber blend is written as 1.606g on the label, but we rounded it up to 1.6g below.

  • Fiber blend (1.6g): The three ingredients in this blend are chicory root fructooligosaccharides, flaxseed, and apple fruit powder.
  • Green superfood blend (1.4g): Ingredients in this blend include some familiar names, like barley grass, spirulina, wheatgrass, alfalfa, and chlorella.
  • Pre and probiotic blend (648mg): This blend contains blue agave inulin, Bifidobacterium bifidum, Lactobacillus rhamnosus, and Lactobacillus acidophilus.
  • Fruit and vegetable blend (572mg): Carrot, beetroot, kale, blueberry, spinach, broccoli, and ginger extract make up this blend.
  • Antioxidant blend (550mg): Some ingredients include cranberry, strawberry, raspberry, tart cherry, elderberry, and matcha green tea leaf.
  • Digestive enzyme blend (150mg): Ingredients include maltodextrin, amylase, amyloglucosidase, protease, acid protease, cellulase, and lipase.
  • Adaptogenic blend (100mg): This blend includes licorice root, Rhodiola root, American ginseng, ashwagandha, astragalus, and eleuthero root.

Note: Like with Amazing Grass, the inclusion of fructooligosaccharides (F.O.S.) makes Bloom unsuitable for people with certain FODMAP sensitivities.

You may be able to see how Bloom’s priorities differ from our other top picks; adaptogens come in last, while the fiber blend is the main focus. Bloom’s greens also possess a larger pre- and probiotic blend than our other picks. This may be due to a large amount of blue agave inulin, but it’s still interesting to see this type of blend so high up on the ingredient list.

The green superfood blend checks off many of the most common greens powder ingredients, all of which have some potential to provide health benefits. For instance, barley grass may improve your digestive functioning, and spirulina might support your immune system.


As with all of our other top picks, Bloom offers a subscription savings option; it’s the lowest discount of the bunch, however (10%). And, like Amazing Grass, Bloom’s return policy is less than stellar — you only have 15 days to make a return, and the product must be unopened.

The chart below explains the pricing for Bloom’s Greens & Superfoods (all flavors cost the same).

CostCost per serving
30 servings; single purchase$39.99$1.33
30 servings; subscription (10% off)$35.99$1.20
60 servings; single purchase$74.99$1.25
60 servings; subscription (10% off)$67.49$1.12

For how little you appear to get nutrient-wise from Bloom’s Greens & Superfoods, the price feels like a bit much. The same amount of money for a 30-serving single purchase would get you the same from Amazing Grass, which offers more nutrients. Or, even better, you could save $10 and purchase our runner-up pick, Nested Naturals (that savings becomes $20 if you opt for the chocolate variety).

Thankfully, though, all U.S. orders from Bloom ship for free, and your order should arrive within the week (ours took about five business days). This is the only one of our top picks that offers free shipping no matter the total of your order, and it’s a stark difference from Orgain’s $75 minimum order requirement.

Other greens powders

The two greens powders in this section are ones we enjoyed for one reason or another, but they didn’t quite make our top picks list. However, they might appeal to you for their unique qualities, so we’ve included some information on them below.

Texas SuperFood

Texas SuperFood boasts an extensive list of 55 ingredients that includes digestive enzymes and probiotics. It is the only product among our top choices labeled safe for adults and children over the age of 12 (but we always recommend speaking with your child’s pediatrician before starting them on a supplement). While it's not certified organic, Texas SuperFood contains no common allergens and is vegan-friendly. Something we appreciate is that you can purchase the product in powder or capsule form, allowing you to bypass the taste of greens powder if you choose.

Interestingly, Texas Superfood’s supplement facts don’t list any vitamin or mineral content (besides sodium), and all of the ingredients are housed in one massive blend labeled as, simply, “Proprietary Blend.” Similar to Orgain’s Organic Superfoods, this makes the ingredients list even more obscured than the ones using a bunch of different blends. With AG1, for instance, you can at least look at the supplement facts and learn that there are 154mg worth of the ingredients listed in the Digestive Enzyme & Mushroom Complex per serving — this isn’t as transparent as we’d prefer it to be, but it still provides some additional information.

Examining the cost, Texas SuperFood single-purchase prices come pretty close to AG1’s, both for the capsules and powder. Both forms of the product cost about $2.67 per serving when purchased as a one-time, 30-serving supply. However, if you buy in bulk (90 servings) through the company's Subscribe & Save program, you can drop that cost to $2.05 per serving.

Texas SuperFood provides free ground shipping on any order within the U.S., and subscribing gets you free expedited shipping.

Single PurchaseSubscribe & Save
30 servings$79.95$69.95
60 servings$147.10$128.70
90 servings$211.08$184.68

Supergreen Tonik

Supergreen Tonik is a dairy-, egg-, and soy-free (but not tree-nut-free) greens powder that combines 38 plant-based superfoods, adaptogens, and nutrients with the intent of boosting your immunity, energy, and focus.

Something unique about this product is that the company lists the exact milligrams of each ingredient per serving. This is one of the only greens powders we’ve seen do that; the next closest thing is Nested Naturals listing its spirulina and chlorella content.

Similar to AG1, Supergreen Tonik has 100% or more of the recommended intake of multiple vitamins and minerals, including:

  • Vitamin C
  • Vitamin D
  • Thiamin
  • Riboflavin
  • Niacin
  • Vitamin B6
  • Vitamin B12
  • Biotin
  • Pantothenic acid
  • Zinc
  • Copper

While none of our top five picks have an amount of iron close to your daily recommended amount, Supergreen Tonik reaches 61% by adding supplemental iron in the form of ferrous salts (specifically ferrous fumarate). This may sound like a good thing at first, but iron can potentially pose a danger when combined with high amounts of supplemental ascorbic acid (vitamin C).

Supplementing both ferrous salts and ascorbic acid improves absorption, which can increase the risk of iron overload and may exacerbate oxidative stress in the digestive system. Researchers note that this may lead to:

  • Ulcers
  • Inflammatory disorders
  • A worsening of pre-existing chronic conditions
  • Increased risk of certain cancers

This is due to the start of “redox interactions” between the two nutrients (the way the two swap electrons). Basically, the way vitamin C and iron interact may turn any antioxidant properties of the former into pro-oxidant ones.

And, pivoting toward its 222% Daily Value of copper (2mg), some research suggests that diets high in copper (about 2.75 mg per day) and certain fats (saturated and trans fat) may accelerate cognitive decline in older adults.

However, despite these potential risks, Supergreen Tonik is likely safe for most people, but it’s worthwhile to keep this info in mind.

In terms of cost, Supergreen Tonik is pretty close to AG1 while having almost the same number of ingredients as our runner-up, Nested Naturals (which costs a lot less and is certified organic). And Supergreen Tonik doesn’t have an additional focus on fiber or probiotics like our top picks. Considering all of this, it almost feels like you have to pay for the company’s ingredient transparency.

Supergreen Tonik also doesn’t offer a subscription savings plan. However, purchasing in bulk can save you over 25% on each order. (You can also save an additional 10% using code INNERBODY10.) And shipping is $9 for the 1-month supply, but free for the 3- and 6-month bundles.

CostCost with promo code INNERBODY10Cost per serving with our discount
1-month supply$87$78.30$2.61
3-month supply$227$204.30$2.27
6-month supply$377$339.30$1.89

Insider Tip: If you select “Try Mint + Berry” under the flavor options, you’ll get an offer to purchase one of each flavor at a discount. Normally, two tubs would cost $174, but the offer makes it $153 (or $137.70 with our promo code).

Unlike AG1, there aren’t any free gifts included in your purchase (like the AG1 bottle, storage container, and scoop). At checkout, you’ll be offered the chance to purchase a Human Tonik (the company behind Supergreen Tonik) bottle for $10 instead of $15, but that’s it.

Additionally, Supergreen Tonik comes with a 1-year satisfaction guarantee. But, there’s a little asterisk on that guarantee; when you scroll down on the page, there’s a statement that reads: “Applicable to one opened tub minimum. If you place an order of 2+ tubs, you must return all unopened products to receive a full refund.”
