Once a niche athletic supplement, branched-chain amino acids (BCAAs) have exploded in popularity as a means to improve muscle retention, fat loss, endurance, and focus during workouts. Today, hundreds of different BCAAs on the market include stimulants, adaptogens, micronutrients, and extracts to make them stand out from the crowd. Our goal here is to help you find the best BCAA supplements for muscle gain, for keto dieters, for weight loss, and a lot more.

It’s not uncommon to see BCAAs packaged with other supplements like caffeine, glutamine, taurine, beta-alanine, citrulline malate, and other ingredients that may benefit workout performance. In this article, we’ve taken the BCAAs, the extra components, the price, and the taste into account when deciding the best brand depending on your goal.

Best BCAAs Powder Overall

A BCAA formula with zero unwanted artificial flavors, only the essential ingredients, and that’s vegan-friendly is what we decided to be the best

Transparent Labs BCAA Glutamine

A rare BCAA powder that is both vegan-friendly and comes with some welcome additions like coconut water powder and extra glutamine, Transparent Labs has made a simple supplement that will check a lot of must-have boxes for consumers. It has eight grams of quality BCAAs, with five grams of glutamine, too. It’s also free of artificial flavors, colors, ingredients, and preservatives.

This glutamine supplement is gluten-free, non-GMO, and free of artificial preservatives. Each container provides 30 servings that contain 5000 milligrams of L-Glutamine and 1,535 milligrams of Vitamin C.

Who Should Buy Transparent Labs BCAA Glutamine

  • Athletes looking for a quality vegan BCAA supplement. This one packs eight grams of BCAAS, five grams of glutamine, coconut water powder, and citric acid.
  • Lifters who want a supplement without artificial flavors, colors, ingredients, or preservatives. Transparent Labs’ formula has none of these extras. 
  • Vegans and vegetarians. Transparent Labs’ BCAA product is vegan-friendly. 

Who Shouldn’t Buy Transparent Labs BCAA Glutamine

  • BCAA Glutamine has some solid additions, but if you’re looking for a supplement with a ton of extra vitamins and electrolytes, other options might be more appealing
  • People who want a very sweet tasting supplement regardless of flavor. This one tastes a tad dull.

Not overly complicated, but appealing to many: Transparent Labs has made a BCAA supplement that gets a lot of points for hitting the basics well.

Best BCAA for Men

For men who are going hard in the gym to build muscle, a dose of BCAAs may help you pump longer and harder. This particular supplement provides 7,000mg of BCAAs and a dose of electrolytes for hydration.

Plantrise Amino Complex

While many of BCAAs’ properties revolve around recovery, they can also help increase muscle growth. The amino acid leucine is particularly key for building muscle as it can stimulate muscle protein synthesis, and since amino acids can be depleted as you exercise, it’s important to make sure you start out with enough to work with. Plantrise contains 3,500mg of leucine, as well as other BCAAs, like l-isoleucine and l-valine. Plus, there’s an added dose of coconut water powder for hydration to make sure you’re hitting all your marks 20 to 30 minutes before your workout. It’s worth noting that this supplement only comes in one flavor — blue raspberry — though, so if you’re looking for flavor variety, you will not find it here.

Made with 7,000 BCAAs, this formula is also infused with 50mg of coconut water to provide added electrolytes for hydration, and it comes in a delicious blue raspberry flavor. 

Who Should Buy Plantrise Amino Complex

  • Men who want a BCAA supplement they can take pre-workout to make sure they are starting their session off with plenty of amino acids. 
  • Anyone who’s going hard at the gym and is looking for an increase in energy and endurance and a decrease in fatigue.
  • Athletes who are concerned about dehydration and want a BCAA supplement with coconut water powder to help stay hydrated. 

Who Shouldn’t Buy Plantrise Amino Complex

  • Buyers who want to have more than one option in flavor — this product only comes in blue raspberry.
  • Anyone who would prefer a BCAA supplement they should take mid-workout. There are intra-workout BCAAs out there. 

Though BCAAs can help with recovery, they can also be a part of a balanced pre-workout supplement to potentially help with muscle growth, endurance, and energy. This supplement provides a solid dose of leucine, as well as other supplements like coconut water powder for a well-rounded pre-workout beverage. 

Best Intra Workout EAAs 

Essential amino acids contain all three BCAAs — leucine, isoleucine, and valine — but they also contain the other six EAAs. This is one of our favorite intra workout supplements that includes all nine essential amino acids. 

Transparent Labs Intra Workout EAA

Transparent Labs Intra Workout EAAs is ideal if you’re looking for a supplement that not only contains the three BCAAs, but also contains the six additional EAAs. This product contains 6.7 grams of EAAs, as well as two grams of citrulline malate and one gram of ElevATP®, which both may help with strength, endurance, and power output. Plus, Transparent Labs also includes one gram of coconut water powder to potentially help with hydration during your workout. This product also comes in a Strawberry Lemonade that is quite tasty.

Transparent Labs Intra Workout EAA not only contains the three BCAAs, but it also contains the six additional EAAs. This product includes 6.7 grams of EAAs, as well as two grams of citrulline malate and one gram of ElevATP. 

Who Should Buy Transparent Labs Intra Workout EAA

  • For those who prefer to have all nine essential amino acids in their supplement instead of just the three BCAAs, this EAA supplement is ideal. 
  • Anyone who wants coconut water powder included in their EAA supplement for added hydration throughout their workout. 
  • If you want a potential boost in strength or muscle endurance, you’ll appreciate this product’s citrulline malate. 

Who Shouldn’t Buy Transparent Labs Intra Workout EAA

  • Anyone who is just looking for a BCAA supplement and doesn’t need the additional six EAAs included with their BCAAs. 
  • Folks who want a variety of flavors to choose from may need to look elsewhere, as this product only comes in Strawberry Lemonade. 

Athletes who need to perform at high-levels can benefit from this dialed-in EAA formula made for intra-workout performance.

Best BCAA Pills 

There are a lot of benefits to taking your BCAAs in pill form instead: you can take them with you to the gym or on the road, which is great if you’re going long periods between meals, as you do when you’re out and about.

Performance Lab BCAA

These are our favorite Branched Chain Amino Acid pills. These are extremely straightforward, with very few added ingredients and the 2:1:1 ratio that many customers are looking for in their BCAA supplement. Performance Lab BCAAs are fermented and vegan-friendly.

Best BCAAs for Muscle Gain

If muscle growth is your goal, then your primary concern should be eating enough calories and macronutrients throughout the day. (Here’s a calculator for that.) But when it comes to BCAAs, you might want something that supports in-gym performance and offers optimal BCAA ingredients.


Some BCAA supplements are just that — a product that offers up only branch chain amino acids. That’s fine, but if you’re looking to build muscle then you ned a supplement that will assist you in doing so. What makes In-Kaged that formula is it’s focus and blood flow formula to help you feel and perform better in the gym while also jump-starting the recovery process.

  • People who want lots of choices in flavor variety, as this only comes in fruit punch.

Sculpt Nation’s BCAA product is one of the simplest we’ve tried. For some, that’s a big bonus.

Best BCAA for Weight Loss 

Many take BCAAs to help preserve muscle when in a calorie deficit, and some products even add extra ingredients with links to weight loss. 

Disclaimer: Please note that none of these products describe themselves as weight loss supplements and should not be taken as such. Please consult with a medical professional before beginning any weight loss protocol.

IdealLean BCAAs for Women 

IdealLean BCAAs for Women had the most dedicated weight loss ingredients. This includes evodiamine, a berry extract that’s been linked to fat loss in rodent studies; green tea extract; and CLA, a type of fat that may help with weight management. Note that these ingredients are present in relatively small amounts, but there may be some effect.

  • Those who are skeptical about supplement dosing, as the ingredients listed, though effective, may be dosed too little. 

Weight loss is all about your calories, not your supplements, but IdealLean has put together an impressive BCAA supplement that may be more helpful for weight loss than others.

Best BCAAs for Electrolytes

While many BCAAs include micronutrients — like Vitamin C and B-Vitamins — in addition to the BCAAs, this pick includes electrolytes to help promote optimal hydration. 

Plantrise Amino Complex

Plantrise Amino Complex is a blend of essential amino acids, which are high in branched-chain amino acids. Along with 7,000 BCAAs, this formula is also infused with 50mg of coconut water to provide added electrolytes that can help with hydration, potentially leading to better athletic performance and endurance. It comes in a blue raspberry flavor and mixes seamlessly with water for easy digestion 20 to 30 minutes prior to your workout.

Best BCAA for Keto Dieters

Ketogenic diets are ultra low carb and often relatively low in protein, so many supplements with branched-chain amino acids to help retain muscle. 

Cellucor Alpha Amino 

Cellucor Alpha Amino is our top choice for people on a ketogenic diet. It has very few calories and no carbs, so there’s little risk of it kicking you out of ketosis, and it’s also pretty high in magnesium, sodium, and potassium — minerals that are usually recommended as important supplements for people following the high-fat diet.

With zero grams of sugar, this is an ideal formula for anyone on the low-carb, high-fat keto diet. It also packs 750mg of creatine HCL for improved in-gym performance. 

Who Should Buy Cellucor Alpha Amino

  • If you’re on a keto diet, this product won’t take you out of ketosis.
  • The extra electrolytes here may make it a useful supplement for those who want help with hydration.
  • Alpha Amino happens to be soy-free, so it’s good if you’re avoiding soy.

Who Shouldn’t Buy Cellucor Alpha Amino

  • This one is a little pricier than your average offering at 17 cents per gram of BCAAs. Penny pinchers may want a cheaper product.

BCAAs are particularly popular among those limiting their protein intake. If you’re finding your high-fat meals lacking in protein, BCAAs might be a good addition to your diet.

How We Decide the Best 

There are several elements we looked at — and dozens of products — to land on this list of the best BCAAs. Here’s our list that we looked at every time we assessed a supplement’s efficacy.

Amino Acid Ratio

The standard formulation for these products is two or three grams of leucine for every gram of isoleucine and valine. Although some products have many times more leucine, this hasn’t been shown to be more successful than the “classic” ratios.

Ergogenic Effects

In addition to BCAAs, many products — including our number one pick — include ergogenic aids or ingredients linked to improved performance. These include citrulline (related to improved circulation), beta-alanine (endurance), and caffeine (explosive power).

Lipolytic Effect

Some of the BCAA products we highlighted are because they include extra ingredients that may exert lipolytic or “fat-burning” effects. These include conjugated linoleic acid, green tea extract, and evodiamine. Fat loss is almost entirely about how many calories you burn in a day. Still, some limited research has suggested ingredients like these can help break down fatty acids, particularly during exercise.


Many BCAAs include extra Vitamin B6, which may help with muscle retention and which the body appears to lose during intense exercise. But many others have other B vitamins in addition to other micronutrients: Vitamin C may help to limit oxidative damage during exercise, and sodium may help with hydration.


A well priced BCAA is about 12 cents per gram of BCAAs. If a product costs significantly more, such as IdealLean, it would only make the list if it had additives that justified the price.

What Are the Benefits of BCAAs?

You might have heard that amino acids are the building blocks of protein, but they’re not all alike. The three proteinogenic branched-chain amino acids, meaning BCAAs that are incorporated into proteins during translation, are leucine, isoleucine, and valine.

Some evidence suggests that supplementing with pure BCAAs can positively affect workouts, mainly if you’re working out on an empty stomach or if you haven’t eaten much protein throughout the day. This is because they may promote muscle protein synthesis, and by preventing a serum decline in BCAAs (which occurs during exercise), they can help prevent fatigue. (1)(2)(3) They’ve even been linked to increased fat loss and quicker reaction times. (4)

Note that if your priority is muscle mass, you still need to eat enough calories and protein, get enough sleep, eat the right micronutrients, and so on. Nonetheless, on days when you haven’t been hitting every macronutrient goal, many athletes find BCAAs useful.

What’s In Your BCAA?

We know that supplements, particularly ones like these, can involve a lot of jargon and be tough to understand for the average person. Let’s break down what you’re most likely to see on your ingredients label, starting with the three branched-chain amino acids.

BCAA Supplement Powder


Perhaps the most highly prized of all the amino acids, leucine has the closest link with boosting muscle protein synthesis. While your total calories are essential for muscle growth and muscle retention, muscle protein synthesis is a vital part of the puzzle.


Used in the biosynthesis of proteins, this branched-chain amino acid may prevent muscle breakdown, and promote fat burning.


Another essential amino acid, valine, has some links to endurance and focus. Interestingly, suppose you have difficulty digesting it and there’s more of it in the blood. In that case, this is seen as a sign of insulin resistance, a risk factor for diabetes and other conditions.

Then there are these other amino acids that aren’t BCAAs, but often accompany them in supplements:


A conditionally essential amino acid (remember amino acids are building blocks of protein) glutamine is enormously popular in supplements because it has some muscle gain links. However, most research has only seen this among people whose bodies are in trauma, like victims of burns or stab wounds — it hasn’t translated to gains for gym-goers.


A ubiquitous addition to pre-workouts, one-and-a-half to four grams of the stuff has shown to improve endurance and possibly hypertrophy. It’s possible that it also has some anti-aging effects, as it increases the amount of carnosine, an antioxidant, in the body.

Citrulline Malate 

An amino acid that’s prevalent in watermelons (along with legumes and organ meats), citrulline appears to improve nitric oxide metabolism, which leads to better circulation and blood flow. In workouts, this means better endurance and power output. It’s also common in erectile dysfunction supplements. 

L-Carnitine L-Tartrate  

This amino acid may reduce muscle damage caused by high-intensity exercise. It also has links to longevity, as it may improve mitochondrial function, and it could help retain lean muscle mass and enhance aerobic output.

Vitamin C 

This vitamin may reduce cell damage that occurs during exercise.


The bevy of B vitamins have been thought to increase one’s energy but without jitters or unwanted sleep loss. 

What to Know Before Buying BCAAs

If this is a brand new supplement for you or even if it isn’t, there’s information you should be aware of before going ahead and adding these to your daily regimen. Read on for a few pro tips on taking BCAAs.

Calories Are King

Many take supplements like BCAAs and fat burners because they hear they help with weight loss and muscle gain. BCAAs may help you retain muscle, but it’s essential to keep in mind that losing weight only happens if you’re in a calorie deficit. BCAAs can help with energy levels and make it easier and more productive to work out on an empty stomach — but your total calories will be what makes or breaks your fat loss.  

BCAAs Aren’t Necessary

BCAAs are not necessary if you have a sufficient protein intake. Still, they’re often used as supplements to boost muscle protein synthesis between meals or enhance performance and retain muscle when exercising on an empty stomach. If you’re eating macro-friendly meals throughout the day, these supplements may not be necessary.

Medical Advice

Always speak with your physician before undertaking a new supplement regimen.

Final Word

We tried dozens of branched-chain amino acid supplements when putting together this list — weighing price, taste, ingredients, and effectiveness along with many other factors. Plenty of people have different ideas about what constitutes a “quality” supplement, but we think we’ve put together the most comprehensive guide to aid you in picking the perfect BCAA supplement for your goals. 


What are BCAAs?

It stands for branched chain amino acid. Amino acids are the building blocks of protein and the branched chain amino acids are those most closely associated with muscle protein synthesis, the process by which protein is produced to repair and retain muscle.

What are the benefits of BCAAs?

Evidence suggests that BCAAs may help to retain muscle and improve workout performance, particularly if you’re exercising on an empty stomach or if you haven’t eaten much protein lately. By preventing the serum decline in BCAAs, they may also help to reduce fatigue and muscle soreness during workouts.

Do I need to take BCAAs?

Probably not, so long as you’re eating plenty of protein and calories throughout your day. If that’s the case, taking extra BCAAs around a workout probably won’t serve much extra benefit. Where BCAAs appear to have the most use is when the athlete is exercising on an empty stomach, isn’t eating much quality protein with a meal, or wants to retain their muscle during a fast or during a long period without protein. If you fall into those categories, BCAAs may be useful.

Are BCAAs vegan?

Usually not. Most BCAAs are made from hair or feathers. However, if you look for brands with fermented BCAAs, such as KAGED MUSCLE, then you can be confident it’s vegan friendly.
