Grüns Review

If your daily vitamin and mineral intake isn’t quite where it needs to be, you’re far from alone. Nutrient-poor foods make up an estimated 27% of the typical American diet, leading to many U.S. adults meeting or exceeding their daily calorie needs without reaching other essential nutrient requirements.1 This often means low levels of vitamins A, C, D, and E, along with certain minerals, like magnesium.1 2 Deficiency symptoms can include things like fatigue, mood swings, aches and pains, cognitive difficulties, and decreased immune function — all of which can have a profound effect on your daily functioning.3 4

Besides a healthy diet, some people may try to fix deficiencies through supplementation, which can be beneficial.3 One type of nutritional supplement, greens — typically in the form of powders — have been growing in popularity over the past few years, but not everyone can get past their “green” taste. This is where Grüns greens gummies may be able to help. The manufacturer states these fruit-flavored, nutrient-rich gummy bears are a stress-free way to fill nutrition gaps while improving gut health, brain health, immunity, and sleep, among other benefits. But do these claims hold up?

In our review of Grüns, we break down the details of their efficacy, safety, cost, taste, and more to help you decide if they’re right for your needs.

Grüns daily greens gummies can be a convenient, tasty alternative for those who can’t get past the often grassy flavor of greens powder drinks. These strawberry-flavored, pectin-based gummy bears come in a bag of 28 individually packaged doses of eight pieces for adults or six for children taking Grüns Cubs. We appreciate the company’s dedication to transparency and testing to ensure high quality. For those with vitamin or mineral deficiencies, Grüns are well-dosed and may be able to provide some tangible health benefits, like improved energy or gut health. However, those without any significant nutritional gaps — or any health concerns directly caused by them — likely won’t see much of a difference. Customers should also be prepared for possible difficulties with subscription management and getting in contact with customer service.

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 our review of Grüns, we spent over 60 hours researching the effectiveness and safety of the various ingredients in these gummies. We also applied our hundreds of cumulative hours investigating and reviewing other similar greens products — such as AG1, Primal Greens, and Bloom Greens & Superfoods — to evaluate Grüns’ place in the market. On top of that, our testers interacted with customer service, purchased Grüns, and tried the gummies to provide first-hand details on the customer experience.

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.

When evaluating any dietary supplement, we typically take into account five criteria that tend to matter most to consumers. These include a product’s safety, effectiveness, cost, convenience, and — in this case — taste. Overall, our findings were that Grüns should be a recommendable option for a large population, especially adults with nutrient deficiencies, but there are some areas in which these gummies performed better than others.

Let’s go over how Grüns fared in each category.

Safety

Since the FDA doesn’t approve or regulate supplements in the same way as prescription drugs, it’s up to the manufacturers to ensure customer safety.5 Thankfully, the makers of Grüns go to respectable lengths to make sure its products are safe for a large population of people. All Grüns products are produced in NSF-certified facilities and are in-house and third-party tested for various contaminants. These vegan-friendly gummies are also free from most major allergens, including dairy, eggs, peanuts, tree nuts, wheat, soybeans, fish, crustacean shellfish, and sesame.

In terms of the ingredients, Grüns should be a generally safe option for healthy adults who aren’t pregnant, breastfeeding, or planning to become pregnant (certain ingredients may be able to cause a miscarriage).6 Additionally, some ingredients could interact poorly with certain medications or medical conditions, meaning that it’s best to contact your doctor before trying Grüns.

When it comes to Grüns Cubs, they should be a safe option for healthy children over the age of four. Though they’re intended for kids aged 2-13, certain vitamin doses in Grüns Cubs may be a bit too high for those aged 2-3.

Effectiveness

Grüns’ potential efficacy greatly depends on the root cause of your concerns. If your health issue or goal is related to a nutrient deficiency, then Grüns’ 100% Daily Value (DV) of 12 vitamins and about 25% DV of eight minerals could certainly help.

However, if what you’re experiencing is not related to a deficiency (or you already eat a healthy, balanced diet), then Grüns may not provide much benefit. For example, having low iron or iron-deficiency anemia can lead to, among other things, fatigue.7 If you’re experiencing fatigue and your iron levels are confirmed to be low via testing by your doctor, then supplementing with Grüns may be able to bring you some relief; a serving contains 4.5mg of iron. But if your fatigue is caused by something else, like a different underlying health condition (e.g., an autoimmune disease), then Grüns aren’t likely to improve your energy levels.8

We cover more details on the effectiveness of Grüns, including some of the research behind the most promising ingredients in the gummies, under the “Do Grüns work?” section later on.

Cost

Greens products are often on the expensive side for a daily supplement, and Grüns are no exception. When compared to the prices of our favorite greens powders, only AG1 is more expensive than Grüns; all of our other top greens powder picks cost roughly half as much. This means that Grüns are middle-of-the-road, leaning toward pricey, for a greens product.

Grüns also suffer from a somewhat complicated pricing structure and a lackluster return policy/guarantee. For example, there are two varieties of Grüns: low-sugar (the original) and sugar-free. The sugar-free Grüns for adults are always nearly $10 more expensive than the original option, even with a subscription or bulk discount, but this price difference doesn’t exist for the different Grüns Cubs options.

The prices for low-sugar and sugar-free Grüns for adults look like this:

Pivoting to the aforementioned return policy — which is also the guarantee — the company’s 30-day money-back guarantee only applies to your first purchase of Grüns; all subsequent purchases are final sale. Moreover, your return will incur a $5 fee, and you won’t get back any of the shipping cost if it was a one-time purchase.

Later in this review, we provide more Grüns pricing details under the “Grüns pricing, subscription deals, and refunds” section.

Convenience

Compared to most greens powders, Grüns can be a far more convenient supplement to take. You don’t need to mix them into something like a smoothie or food, and unlike multivitamins in pill or capsule form, you don’t need to have a drink on hand to take them. Additionally, the individually wrapped doses mean you can take your Grüns on the go to work or school (and Grüns Cubs could also be packed alongside a child’s lunch).

Subscription plans also add some convenience to Grüns, since you won’t have to remember to reorder each and every month.

However, that’s where the convenience of Grüns seems to end, as many customers report difficulty canceling subscriptions or trouble contacting customer service. Our testers didn’t run into issues with customer support, but difficulties doing so are such a common complaint that we feel it’s well worth considering for Grüns’ overall convenience rating.

Another potential issue with Grüns involves quantities, specifically the fact that each “month’s worth” of gummies (each bag) only contains 28 servings. The last time we checked, there’s only one month of the year with fewer than 30 days, which means it’s not too far-fetched to imagine customers running out of Grüns before the next subscription arrives.

Taste

If you aren’t a fan of the taste of greens powders, then Grüns can be a great alternative. These gummy bears are supposed to be strawberry-flavored — and they vaguely are — but what they really reminded our testers of were raisins (if you’re a fan of that flavor, like our testers are, then this could be a pleasant surprise). As you chew the gummies, the raisin-like flavor transforms into one more reminiscent of some sort of berry, but it isn’t very “strong” — it’s almost more like a berry aftertaste than the actual flavor of the gummies themselves. Overall, the fruity taste is quite enjoyable, but our testers didn’t pick up on a definite strawberry flavor as the company advertises.

Either way, our testers all agreed that Grüns do not taste “green.” In our guide to the best greens powders, our choice for the best-tasting unflavored option, Amazing Grass Superfood Greens Blend, still tasted like greens; it wasn’t grassy like some greens powders, but it still had a distinct “healthy” taste. And even the various sweetened flavors offered by Bloom Nutrition Greens & Superfoods weren’t enough to make our testers forget they were drinking greens. With Grüns, they don’t taste like actual candy gummy bears, but they’re far less “green” and more akin to a typical gummy vitamin than a greens powder.

Launched in 2023 by the Oregon-based company Grüns Nutrition, Inc., Grüns Super Greens Gummies (often just called “Grüns”) are gummy supplements containing vitamins, minerals, and “core nutrients” intended to bolster your daily nutrition and enhance various aspects of your general health and well-being. Some of the benefits the company claims its gummies can provide include improvements in the following:

Many of these suggested benefits also extend to the company’s offering for kids, Grüns Cubs, intended for children 2-13 years old. The company explains that the ingredients in Grüns Cubs are the exact same as Grüns for adults, just dosed appropriately for younger people’s needs and safety.

No matter the type of Grüns you purchase, each bag of product contains a 28-day supply of individually wrapped daily gummy doses. For adults, that dose is eight gummies, and for kids, it’s six. As pictured below, the gummies are fairly small (they’re basically identical in size and shape to an average gummy bear) and fruit-flavored. Our testers felt that Grüns don’t have any noticeable “green” or “vitamin-y” taste, which could make them ideal for picky kids or those who want to try greens but can’t stomach greens powder drinks.

All Grüns gummies are vegan-friendly — they’re made with pectin instead of gelatin — and are free from common allergens, including dairy, eggs, peanuts, tree nuts, wheat, soybeans, fish, shellfish, and sesame. They’re also third-party tested for quality, purity, and potency (more details on that can be found under the “Are Grüns safe?” section later).

Grüns company reputation

When investigating a company’s online reputation, we typically look for a Better Business Bureau (BBB) page and a Trustpilot one. Grüns has both, and there’s some useful information on each.

Interestingly, the company’s BBB profile (which has a 1-out-of-5-star rating from only ten reviews) went through some changes during the writing of this review. When we initially checked, Grüns’ BBB rating was “F” due to the company not responding to 25 out of 30 complaints, but later it became “NR” (“Not Rated”) because “the business is in the process of responding to previously closed complaints.”

The majority of those aforementioned complaints are about Grüns’ customer service — or lack thereof. While our testers didn’t have any notable concerns with the company’s customer service, a fair number of customers appear to have run into issues like being unable to get in contact with anyone, only receiving generic emails in return, calling and being sent to voicemail, and difficulties canceling subscriptions.

On Grüns’ Trustpilot page, the company has over 420 reviews culminating in a 4.1-out-of-5-star rating — 74% of the reviews are 5-star, 21% are 1-star, and the other 5% are spread out among the 2- and 4-star options. Most reviews are from customers expressing how much they enjoy the gummies, including their flavor, convenience, and benefits to digestion. The negative reviews are similar to those from the BBB page and mainly involve difficulty either contacting customer service or canceling subscriptions.

Though there aren’t all that many reviews on either platform, many of the complaints are nearly identical. So, while those who enjoy Grüns seem to be happy with their experience, it seems like the company may need to put some serious work into improving its customer service for those who aren’t happy.

Grüns could technically be for any adult — not pregnant or breastfeeding — who wants to try them (or for kids aged 2-13 whose parents would like them to try Grüns Cubs). However, the information on the product page indicates that Grüns are mainly intended for those with nutrient deficiencies or who aren’t fans of powdered greens products.

As with similar nutritional supplements, like AG1 and other greens powders, Grüns will likely be best suited to those who don’t already eat a balanced diet containing adequate amounts of vitamins and minerals from a variety of fruits and vegetables. The same can be said about Grüns Cubs for kids.

Who should look elsewhere?

There are a few groups of people that may be better off with a different supplement or greens product, including the following:

• People who are pregnant or nursing: There isn’t enough research on the safety of the various herbal ingredients in Grüns for those who are pregnant or breastfeeding. Moreover, one ingredient — astragalus — has demonstrated abortifacient properties in some research (it could lead to a miscarriage). 6
• Those who aren’t deficient in any nutrient: Any potential benefits that users of these gummies may notice are likely due to them being deficient in a vitamin or mineral and then getting what their body needs from Grüns — but much of the same could also be accomplished by a quality multivitamin. All this is to say that if you eat healthy, Grüns may not be what you need. Other supplements may be better for achieving your goals (like ashwagandha for stress or magnesium for sleep).
• Individuals taking medications or with certain medical conditions: Some ingredients in Grüns may interact poorly with various medications or medical conditions. For example, spirulina and astragalus both may interfere with immunosuppressant drugs,9 10 and mangosteen may slow blood clotting and interact with the Alzheimer’s drug donepezil.11 (These examples are far from comprehensive, so speaking with your doctor is recommended before trying Grüns.)
• Younger children: Children’s nutrient needs change pretty quickly when they’re very young. Grüns Cubs are intended for kids aged 2-13, but those aged 2-3 have different daily nutrient recommendations than those who are 4-13. Kids ages four and older should be fine, but the doses of certain vitamins (such as vitamin A) in Grüns Cubs may be too high for those younger than age four.12
• People who have trouble swallowing (dysphagia): Though Grüns may be easier to take than capsules or pills because they can be chewed into a smaller, softer mass, some people may still have difficulty swallowing them.13 In those cases, a greens powder that can be mixed into a liquid beverage — like AG1 — may be a better choice.

Grüns should be generally safe for healthy adults who aren’t pregnant or breastfeeding, and the same applies to Grüns Cubs for most healthy children over the age of four (more details on that in a bit).

All Grüns gummies are manufactured in NSF-certified facilities in the United States and Canada. The company conducts in-house and third-party testing for quality, purity, and potency. The purity part of the testing includes analysis for contaminants, microbes, pesticides, and heavy metals. In addition, Grüns are vegan-friendly and free from most common allergens, including dairy, eggs, peanuts, tree nuts, wheat, soybeans, fish, shellfish, and sesame.

Now, when it comes to the ingredients in Grüns, there are a couple of groups for whom these gummies may not be safe.

• Those who are pregnant, nursing, or planning to become pregnant shouldn’t take Grüns because most of the herbal ingredients in the gummies haven’t been studied for safety in those populations, and astragalus may cause a miscarriage. 6
• People with medical conditions or who are taking medications should proceed with caution and get the all-clear from a doctor before trying Grüns, as certain ingredients may interact poorly. Mangosteen, for example, slows blood clotting and can interfere with donepezil (a drug for Alzheimer’s).11

Additionally, it’s important to mention that the vitamin and mineral doses in Grüns Cubs may be too high for kids 2-3 years old — particularly the fat-soluble vitamins A, D, E, and K.15 The most worrisome one is vitamin A, which is offered in a 149% Daily Value (DV) dose for kids aged 2-3 (this drops to a safer 50% DV dose for kids over age four). Because younger children have a lower body mass, they’re at greater risk of developing acute vitamin A toxicity, or hypervitaminosis A, from small supplemental doses.12 16 However, with a pediatrician’s approval, children over age four should be fine to take Grüns Cubs.

As a supplement meant to improve nutrient deficiencies, Grüns should work just as well as any other quality multivitamin or greens product.

Each daily Grüns dose contains 100% Daily Value (DV) of 12 vitamins, around 25% DV of eight minerals, 6g of dietary fiber, and 8,670mg of a proprietary Core Nutrients Blend. Studies comparing the bioavailability of a few different vitamins (namely B12, D, E, and folate) in tablet and gummy forms have found that their absorption is basically equal.17 18 The only exception is vitamin D, which actually demonstrated higher bioavailability as a gummy.19 So, with this data in mind, the nutrients in Grüns should be able to be absorbed and readily used by the body.

However, it’s important to point out that many of the suggested health benefits from Grüns are most likely due to a nutrient-deficient body receiving the necessary vitamins and minerals the gummies provide. For example, a B12 deficiency can lead to depression, memory issues, fatigue, difficulty thinking, and more.4 So, if low B12 happens to be the cause of your brain fog or low energy, then Grüns may “work” to fix it just by giving your body the nutrients it needs — but any other worthwhile B12 supplement would do the same thing. On a similar note, if you already eat a balanced diet and aren’t deficient in any vitamins or minerals, Grüns may not do all that much for you.

Something else worth clarifying is a few statements on Grüns’ product pages. At one point, the company notes, “Over 35,000 research publications support the efficacy of Grüns.” This wording is very misleading. At the time of this writing, Grüns themselves have never been studied.

Those 35,000 studies are on the ingredients in Grüns, meaning the company is referring to all of the studies conducted on every vitamin, mineral, botanical, and other nutrient in the gummies. One of the reasons this is misleading is that the statistics on the product page aren’t about Grüns at all. For example, the statement describing a “41% increase in healthy gut bacteria within 16 days” isn’t a data point directly observed as a result of people using Grüns — it’s likely information taken from a study on an included ingredient, like inulin or tapioca fiber, both of which can greatly benefit gut microbiota.20 This isn’t to say that Grüns can’t improve your gut health, but it feels rather dishonest for the company to imply attribution of these statistics to its product.

That being said, let’s review some of the research behind how the ingredients in Grüns may lead to the most prominent benefits claimed by the company.

Though the inclusions in Grüns do show a fair bit of promise, we hope the company will consider using less misleading language when describing (technically unrelated) research done on the ingredients. It’d also be nice to maybe see the company conduct or sponsor studies on the actual product some day. A competing greens product, AG1, for example, has been examined in multiple pieces of peer-reviewed research, including a clinical trial investigating the product’s impact on human subjects’ gut microbiomes.

Unfortunately, Grüns’ pricing can get a bit complicated. While there are some commonly seen factors like subscription and bulk purchasing discounts at play, there are also some noteworthy price differences between the low-sugar (original) and sugar-free varieties. The chart below shows how it all breaks down.

Note: A “month’s supply” of Grüns (one bag) is 28 servings.

As you can see, sugar-free Grüns can be up to almost $10 more than the original low-sugar variety (which contains 8g of added sugar per serving). The only potential reason for this price difference that we can determine is that the company uses a sugar substitute called OnoSweet in the sugar-free Grüns. OnoSweet is a branded form of Reb M, or rebaudioside M, a zero-calorie sweetener from the stevia plant that is purported to taste more like actual sugar than regular stevia does.32 The higher cost of Reb M could very well be due to it being a fairly new sweetener option; its production was approved by the FDA less than a decade ago.33

Pivoting to Grüns Cubs, these gummies can only be purchased as a monthly subscription, but you can buy bulk quantities for up to five kids. Like the adult variety, there are low-sugar and sugar-free options available for Grüns Cubs. Here’s how the pricing works out:

• One kid: $50.24
• Two kids (26% off): $98.48
• Three kids (27% off): $146.22
• Four kids (28% off): $192.96
• Five kids (29% off): $238.65

Interestingly, there isn’t a price difference between the low-sugar and sugar-free Grüns Cubs like there is with Grüns for adults, even though Grüns Cubs also use the same OnoSweet branded Reb M sweetener.

Additionally, it’s worth mentioning that all varieties of Grüns can potentially be purchased using HSA/FSA funds through Truemed. However, we recommend checking with your plan before trying to use your HSA/FSA funds, just in case — Truemed claims can still be denied.

Grüns refunds and money-back guarantee

Grüns only accepts returns or offers refunds on your first purchase. The return policy and 30-day money-back guarantee are basically one and the same. Subsequent purchases are final sale.

If you aren’t a fan of your first Grüns purchase, you do have 30 days from the date you receive them to request a refund. Note that submitting a return request does not cancel your subscription; you will need to do that separately. Each Grüns return incurs a $5 fee and your shipping costs are not included in the refund. To illustrate, if you made a one-time purchase of the low-sugar Grüns and paid $91.19 total (the product cost plus shipping), then you’ll only get back $74.99 after the fee is taken out.

If you aren’t quite sold on Grüns or if you’d like to know more about your other options first, we’ve detailed a few alternative avenues below that could bring you some of the same potential benefits.

Greens powders

Though Grüns were made as a gummy alternative to greens powders, these mixes still serve as an alternative to Grüns in return. Most quality greens powders will also offer a hearty dose of vitamins and minerals along with various vegetables and herbs, meaning they should be able to provide similar nutritional benefits. Price-wise, greens powders run the gamut from about $15 (Orgain Organic Superfoods) all the way up to around $100 (AG1). However, like with Grüns, subscriptions and bulk purchases can often lower these costs substantially, which is important for those looking to take these products long-term.

For more information on greens powders — including details on our top picks — check out our comprehensive guide.

Multivitamins

If you’re not all that interested in the greens part of Grüns, but like the idea of adding more vitamins and minerals to your regimen — or if Grüns are simply too pricey for long-term use — then a multivitamin can be a more affordable option that packs the same nutritional punch. Some multivitamins on the market even include vegetable or herbal ingredients, too.

If you’re not sure where to start looking for a multivitamin, we’ve written multiple guides to the best options for different populations and needs. Here are a few:

• The Best Kids Vitamins
• Best Men’s Multivitamin
• Best Multivitamin for Women
• Best Vitamins for Energy

A healthy diet

Though we’ve all heard it before, eating a healthy, balanced diet really could bring you some of the same benefits as Grüns if your concerns stem from a vitamin or mineral deficiency.

For example, a serving of Grüns contains 900mcg of vitamin A, but one cup of baked sweet potato contains about 960mcg.34 Of course, one thing Grüns definitely have going for them is convenience; it’s much easier to eat a few gummies than it is to go grocery shopping and then plan/cook certain meals in order to make sure you’re meeting all your nutrition requirements. Nonetheless, a healthy diet is a viable alternative to Grüns.
