Best Amino Acid Supplements: Top 6 of 2022

We examine the six best amino acid supplements based on quality, effectiveness, value, and safety.

Last Updated: Jun 8, 2022
Best amino Acid Supplements

You don’t have to be a bodybuilder or an athlete to benefit from amino acid or branch-chain amino acid (BCAA) supplementation. Amino acids are the building blocks of protein, providing your body with the means for cell growth and repair and contributing to overall health. This fast-growing market is estimated to value over $37.6 million by 2028.

If you are among the nearly 50% of Americans trying to lose weight, amino acid supplementation may contribute to your goals. These supplements are generally taken during workouts to help your body build muscle and improve athletic performance, which can help you lose weight and keep it off longer. They can also boost your endurance and reduce post-workout soreness and fatigue.

All amino acid supplements are not created equally, however. This guide breaks down the top six amino acid supplements of 2022 based on their effectiveness, cost, safety, and customer satisfaction.

If you don’t have time to read our complete guide, glance over our top picks below.

Summary of recommendations

Our Top Choice

Thorne Amino Complex

Not only is it a highly potent and top-quality product, but Thorne’s supplement is the only one certified for sport.

Vegan-friendly and available in two tasty flavors, this powder packs the punch athletes are looking for. Plus, you’re protected by a 60-day money-back guarantee if dissatisfied.

Top considerations and evaluation criteria

We considered four primary criteria to evaluate our top choices in amino acid supplements: quality, cost, safety, and customer service and satisfaction. Understanding how our top picks performed in these categories can help you decide which product is best for you.

Quality

Winner: Thorne Amino Complex

When buying any supplement, quality should always be the highest priority. Yes, everyone wants to save money, but buying a product that doesn’t work is ultimately a waste. Purchasing a product composed of top-quality ingredients that are certifiably safe and rigorously tested is the best option. Based on these criteria, Thorne Amino Complex is our clear winner.

Thorne Amino Complex is the most comprehensive amino acid supplement among the competition, providing 11 amino acids and potent dosages of the three BCAAs. It’s third-party tested to comply with NSF certification, so if you’re an athlete, you can safely take this supplement knowing it meets the gold standard of quality and contains no banned substances.

Thorne manufactures its products in a cGMP (certified good manufacturing practices) facility in the United States and provides free shipping on all products within the U.S. It supplies a 60-day, 100% money-back guarantee to top off its customer satisfaction qualities. If you’re not satisfied, contact Thorne’s customer service for a full refund.

Cost

Winner: Naked BCAAs

Cost is our second key qualifier when choosing supplements or healthcare products. When we look at cost, we compare the quality of what we’re getting to what we’re willing to spend on it. Most of our top picks for amino acid supplements are reasonably priced, but Naked BCAAs stands out as the most cost-effective choice.

Naked Nutrition’s BCAA formula provides three branched-chain amino acids, sunflower lecithin, and nothing else. This fully transparent company provides exact ingredient amounts and includes no fillers, artificial flavors, or sweeteners in its products. Plus, Naked BCAAs is vegan-friendly, non-GMO, and free of soy and dairy.

Safety

Winner: Transparent Labs BCAA Glutamine

Safety is an important consideration when buying any dietary supplement, in large part because the FDA regulates these products differently than conventional foods and drugs. When considering safety among amino acid supplements, we considered the following factors:

  • Manufacturing methods
  • Ingredient transparency
  • Food allergens
  • Fillers and additives
  • Third-party testing

We’re proud to report that all of our top six picks for amino acid supplements fared well in terms of safety. Ultimately, we chose Transparent Labs BCAA Glutamine as the winner in this category based on its clear labeling of ingredient amounts and its inclusion of high-quality fermented BCAAs, glutamine, and coconut water for added hydration.

Transparent Labs BCAA Glutamine also won us over on taste: we enjoyed every flavor we tried. If the taste of other powders turns you off, Transparent Labs offers five stevia-sweetened fruit flavors that ultimately change the game.

Customer service and satisfaction

Winner: Thorne Amino Complex

Customer service and satisfaction are essential considerations when buying dietary supplements because not everything works for everyone. Strong customer satisfaction means that you can get a full refund when you invest in a supplement that isn’t right for you.

Three of our top picks for amino acid supplements provide 100% money-back guarantees. Even among those three, however, the levels of customer service varied. Thorne provided the most straightforward process for returns with a full refund within 60 days. Moreover, it was easy to communicate with customer service representatives via chat, phone, or email.

Thorne is also the only brand among our picks that offers free shipping on all orders in the US. When you consider the shipping costs of lower-priced brands, this brings Thorne Amino Complex into a closer range in terms of price.

Are amino acid supplements a good choice for you?

Amino acid supplements, particularly BCAA supplements, have appealed to athletes and bodybuilders for years based on their beneficial effects on building muscle while reducing muscle soreness and fatigue during workouts. Today, the market has exploded due to the product’s widespread appeal to the general population.

Amino acid supplements have several benefits for athletes and non-athletes alike, including:

  • Improving athletic performance
  • Developing muscle and strength
  • Reducing delayed onset muscle soreness (DOMS)
  • Balancing blood glucose levels
  • Limiting fatigue
  • Reducing fat

Due to their recovery and cell development abilities, amino acid supplements can even aid those with chronic liver diseases, certain cancers, diabetes, and other conditions, as demonstrated in this 2018 study.

In short, amino acid supplements are a good choice for you if your health goals include:

  • Managing weight
  • Intensifying workout regimens
  • Boosting energy and immunity
  • Promoting better blood glucose regulation

Who shouldn’t use amino acid supplements

Not all supplements are equal, so we tried to include a wide variety of products in our top-six list. If you’re vegan, you’ll want to ensure that your supplement contains no animal byproducts. Five of our top picks are vegan-friendly, but many products are not.

If you have any food allergies, you should talk to your physician or dietician before taking any new supplement, these products included. You’ll also want to check the labeling carefully to see if the product is manufactured in a facility that produces any known allergens.

Because amino acid supplements can impact blood glucose levels, they may interfere with diabetes or thyroid medications. If you’re taking any ongoing medications or have a chronic medical condition, you should consult your doctor before beginning any new dietary supplement.

Amino acid supplements are inappropriate for children under 18 and pregnant or lactating individuals.

How do amino acid supplements work?

Amino acids are molecules that the body uses in forming proteins essential for bodily functions, including:

  • Developing cells
  • Repairing body tissues
  • Digesting food
  • Creating neurotransmitters and hormones
  • Promoting energy
  • Boosting immunity
  • Maintaining healthy hair, skin, and nails

There are three types of amino acids, which we’ll discuss in-depth below:

  • Essential
  • Nonessential
  • Conditional

Essential amino acids

Essential amino acids are those we have to attain from dietary and supplement sources because our bodies can’t produce them. Naturally, these are the kind that amino acid supplements focus on contributing. There are nine essential amino acids, including:

  • Histidine
  • Isoleucine
  • Leucine
  • Lysine
  • Methionine
  • Phenylalanine
  • Threonine
  • Tryptophan
  • Valine

Essential amino acids are naturally derived from food sources, many of which are protein-rich meats. You’ll find essential amino acids in:

  • Poultry
  • Beef
  • Fish
  • Eggs
  • Soy
  • Dairy
  • Buckwheat
  • Quinoa
  • Nuts
  • Seeds
  • Beans

Complete proteins (like the first eight items on the list above) are foods that contain all nine essential amino acids. On the other hand, incomplete proteins have some — but not all — essential amino acids. These foods include nuts, seeds, beans, and some grains.

Vegetarians and vegans need to combine a variety of incomplete proteins to attain all of the essential amino acids in their daily diet. Amino acid supplementation can help ensure those with restricted diets still get all the protein-making compounds they need for optimal health.

Nonessential amino acids

Our bodies can produce nonessential amino acids, which include:

  • Alanine
  • Arginine
  • Asparagine
  • Aspartic acid
  • Cystine
  • Glutamic acid
  • Glutamine
  • Glycine
  • Proline
  • Serine
  • Tyrosine

These amino acids are mostly made from glucose and support tissue growth, immune function, red blood cell creation, and hormonal regulation, among other tasks.

Conditional amino acids

When we’re sick or stressed, our bodies stop producing some nonessential amino acids. These conditional amino acids include:

  • Arginine
  • Cysteine
  • Glutamine
  • Tyrosine
  • Glycine
  • Ornithine
  • Proline
  • Serine

Since these conditional amino acids are still important to keep our body functioning, boosting your levels with an amino acid supplement when you’re not feeling well can help you get back on track faster.

BCAAs

While not formally a separate kind of amino acid, many over-the-counter amino acid supplements focus on BCAAs or branched-chain amino acids. These consist of three essential amino acids:

  • Leucine
  • Isoleucine
  • Valine

BCAAs are among the top supplements for bodybuilders and athletes because they support muscle growth and tissue regeneration and have also demonstrated the ability to reduce delayed onset muscle soreness (DOMS) in clinical trials.

Common ingredients in amino acid supplements

BCAA supplements focus on the three essential branched-chain amino acids (leucine, isoleucine, and valine) in a 2:1:1 ratio for optimum muscle growth and repair during and after workouts. More generalized amino acid supplements contain varying amounts of the nine essential amino acids, with some including other nonessential and conditional amino acids.

It’s key to keep your health and fitness goals in mind when buying an amino acid supplement. If your focus is on bulking up at the gym, BCAAs are generally the way to go. But suppose you’d like a greater variety of amino acids for overall health. In that case, we’d recommend choosing a product like Thorne Amino Complex, which provides 11 different kinds, including BCAAs, essential, and conditional amino acids.

All amino acids provide the materials needed for your body to build protein and function. Vegans or vegetarians may benefit from generalized amino acid supplements because these products cover the ground that protein-rich meats would otherwise provide in an omnivorous diet.

What to expect from an amino acid supplement

The first benefit you’ll likely see when beginning an amino acid supplement is improved muscle gain from working out. Your endurance and strength may increase, allowing for longer, more intense training sessions. Amino acid supplements also help balance blood glucose levels, so you may experience lower or more stable blood sugar.

A big benefit of these supplements is their impact after working out. Amino acid supplements can significantly decrease post-workout fatigue and muscle aches within initial use. Over time, their supplementation will contribute to a more muscular physique.

Amino acid supplements can also have beneficial effects on:

  • Hair
  • Nails
  • Skin
  • Mental health
  • Muscle tone

Are amino acid supplements safe?

Amino acid supplements are generally safe for non-pregnant, non-lactating adults. They produce few side effects, but those that can occur include:

  • Headaches
  • Pain
  • Nausea

Because amino acid supplements impact blood glucose levels, it’s essential to talk to your doctor before use if you take diabetes medications or have any chronic medical condition.

These products should not be used by children under 18.

Frequently asked questions about amino acid supplements

What are the risks of taking amino acid supplements?

Amino acid supplements can cause side effects, including headaches, nausea, and pain. Additionally, since they impact blood glucose levels, they can interact with some medications. If you take any medications, especially insulin or other diabetes medication, you should talk to your doctor before taking amino acid supplements. You should also avoid amino acid supplements before or after surgery. Experts advise against taking a supplement containing just one amino acid, as it can impact how well you absorb other amino acids from food.

Can I take amino acid supplements every day?

You can take amino acid supplements daily as long as you follow the recommended dosage, don’t experience negative side effects, and are not taking other medications or have a chronic medical condition. Consult your doctor if you have questions.

When is the best time to take an amino acid supplement?

Amino acid supplements — particularly BCAAs — should be taken immediately before or during workouts. The main goal of these supplements is to help you increase muscle mass while reducing post-workout fatigue, and they help your muscles repair and rebuild.

Do amino acid supplements have side effects?

Amino acid supplements can cause headaches, pain, and nausea. Some BCAAs may also cause fatigue and loss of coordination. If you experience side effects, you should discontinue use and consult with a physician.

Can amino acids affect your blood pressure?

According to findings in this 2017 study, amino acid supplementation can increase your risk for hypertension (high blood pressure). If you have high blood pressure or are predisposed to it, talk to your doctor before starting an amino acid supplement.

Can I take amino acid supplements with my prescription medication?

If you’re taking any ongoing medication, you should talk with your doctor before beginning any dietary supplements, including amino acid supplementation.

What’s the difference between an amino acid supplement and a BCAA?

Amino acid supplements provide any number of essential, nonessential, or conditional amino acids, whereas BCAA supplements focus solely on the three BCAAs, among the 11 essential amino acids. Both can benefit your body, but the best option for you ultimately depends on your health goals.
