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, keto dieters, 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 BCAA Powder Overall

Our top pick is a BCAA formula with a solid blend of BCAAs that’s effectively dosed without any of the fluff, making it a great option for most customers who want to add more amino acids to their supplement regimen.

For those who already have a solidified regimen and may just be looking for a simple BCAA blend — this product is just that.

Best for Muscle Growth

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

You’ll also find a 5g dose of glutamine, which can help build muscle tissue, as well as coconut water powder for workout hydration. This product comes in four flavors that include both artificial and natural ingredients (so if you’re avoiding artificial ingredients, that’s something you’ll want to note).

Best Total BCAA Blend

This pick not only contains BCAAs, but it has three blends of ingredients working toward power, performance, and support for tough workouts to build out a full package. 

Onnit Total Strength + Performance

Onnit’s formula contains three blends, one of which focuses on BCAAs, but all of which can help you crush big workouts. There’s a Power Blend with longjack, which is a plant that can help provide the fuel you need for muscle contractions. The Performance Blend contains the BCAAs, as well as glutamine and beta-alanine, which can all help you perform better at the gym. Then there’s the Support Blend with resveratrol, which can help you get through tough workouts. 

One of the best parts about this product is that Onnit breaks down each blend, along with the other ingredients — like vitamin B6 and black pepper extract — on their site, so there’s no question as to what each ingredient can help you with. Plus, it comes in a tasty Strawberry Lemonade flavor.

Who Should Buy Onnit Total Strength + Performance

  • Anyone looking for a BCAA supplement that contains other pre-workout ingredients to build out a full performance package. 
  • Folks who like to know what each ingredient’s purpose is in their supplement — Onnit explains each one on its website. 
  • People who value great absorption and are looking for a product with black pepper fruit extract to help with that. 

Who Shouldn’t Buy Onnit Total Strength + Performance

  • Athletes who are looking for a basic BCAA supplement — this is more of an all-inclusive pre-workout blend that contains BCAAs.
  • Those who want to know exactly how many BCAAs they’re getting in their supp — this product’s BCAAs are listed in a blend, so they don’t have an exact dosage. 
  • Buyers on a budget. This is a pretty expensive BCAA supplement because of all the extra ingredients you’re getting.

If you don’t mind blends, this product is a great combination of BCAAs and other performance enhancing ingredients that can act as a full pre-workout supplement. 

Best Protein Powder with BCAAs

Many whey protein powders already contain BCAAs, which means you may not need an additional supplement if you’re already taking a protein powder. This whey isolate contains a particularly solid dose of BCAAs, on top of its overall lean formula. 

Swolverine Whey Protein Isolate

Protein powders, especially high-quality whey isolates, have naturally occurring BCAAs in them. Swolverine’s whey protein isolate has around 5.5g of BCAAs per serving, which comes from 26g of whey protein. While this may be lower than some standalone BCAA supplements, it’s still a solid amount, and if you consider the additional amino acids you get from 26g of protein, that’s a substantial potential stimulus for muscle recovery. 

Aside from including a solid dose of BCAAs from the protein content, Swolverine also includes 10mg of digestive enzymes per serving which may help to break down the larger protein molecules into smaller amino acids for better digestion and absorption. In total, you’ll get 110 calories per serving from half a gram of fat, one gram of carbs, and 26g of protein to help keep your muscles fed. Swolverine keeps the carbs low while still using natural sweeteners like stevia and monk fruit extract. You can buy this powder in Vanilla, Chocolate, Honey Cinnamon Peanut Butter, and Mint Chocolate Chip.

Swolverine Whey Protein Isolate
Swolverine Whey Protein Isolate

This whey protein formula delivers 26 grams of protein with just 0.5 grams of fat, and one gram of carbs. You’ll also find 10mg of digestive enzymes, and a decent number of micronutrients.

Who Should Buy Swolverine Whey Protein Isolate

  • Athletes who want a protein powder that may be easier to digest thanks to the inclusion of digestive enzymes. 
  • Folks who want lean protein that can provide a high proportion of BCAAs. Whey isolates (like this one) specifically tend to have a higher ratio of BCAAs. 
  • If you’re looking for a naturally sweetened BCAA product without a bunch of added carbs or fats you’ll appreciate that this is almost entirely protein. 

Who Shouldn’t Buy Swolverine Whey Protein Isolate

  • There are higher doses of BCAAs on the market if you’re after the highest dose you can find. 
  • If you’re bulking, this lean protein powder may not be the best option for you since it only has 110 calories. 
  • Athletes who just want a plain BCAA supplement will need to look at other options on this list as this is a comprehensive protein powder.

A serving of Swolverine’s whey isolate contains 26g of protein, which provides approximately 5.5g of BCAAs, and remains otherwise lean with just half a gram of fat and one gram of carbs. The added digestive enzymes can potentially help break down the larger protein molecules into smaller amino acids more efficiently, as well, which can help with the effectiveness of the BCAAs.

Best BCAA Pre-Workout

While some may be looking for a straightforward BCAA supplement, others may want to combine their BCAAs and their pre-workout. This pre-workout contains a solid dose of BCAAs to help consolidate your supplement stash. 

Kaged Pre-Kaged Elite Pre-Workout

You’ll find Kaged Pre-Kaged Elite to be one of the most versatile (though higher priced) supplements on this list thanks to its comprehensive formula. Not only is this product a potent pre-workout, but it has a hydration and ATP amplifier as well, featuring 500mg coconut fruit water powder that can help with hydration and 150mg of elevATP®, which may help increase levels of mitochondrial ATP for better energy production. ATP (adenosine triphosphate) is the molecule that our muscles use as currency to make muscle contractions happen (1). It takes time to manufacture more in the muscles, and elevATP® may help to improve that. Amino acids like 10g of l-citrulline and 2,000mg of taurine help to round out the amino profile. 

You’ll find ingredients that may help with energy and pump too, since this is indeed a pre-workout. A potent 388mg dose of caffeine and 3,200mg of beta-alanine, as well as 2,500mg of betaine and 1,500mg of Carnipure® may assist in the energy and skin-splitting pump department. Pre-Kaged Elite isn’t just a BCAA supplement, but an extremely powerful pre-workout and creatine supplement with 5,000mg of combined creatine from monohydrate and nitrate sources. Pick your favorite of three available flavors: Strawberry Lemonade, Glacier Grape, or Fruit Punch, and hop on the gains train.

Kaged Pre-Kaged Elite

Pre-Kaged® Elite provides nine patented ingredients with 35 milligrams of vitamin B6 and 1,000 micrograms of vitamin B12 in a single 36-gram scoop. Each serving is 25 calories and includes caffeine, taurine, l-citrulline, beta-alanine, l-tyrosine, and two types of creatine.

Who Should Buy Kaged Pre-Kaged Elite Pre-Workout

  • Athletes who like a stimulant heavy pre-workout and BCAA product will like Pre-Kaged Elite, which is forward on the stimulants. 
  • Folks who want a blend of potentially energy-boosting and muscle-building ingredients to knock out a number of supplements in one go. This product features creatine, BCAAs, and pre-workout ingredients to combine three products into one.
  • Anyone who prefers to take their BCAAs before their workout — rather than during or after their workout — will like this potent pre. 

Who Shouldn’t Buy Kaged Pre-Kaged Elite Pre-Workout

  • Those who are on a budget — there are other less expensive products on this list. 
  • Anyone who wants to take a more straightforward blend of BCAAs without the added pre-workout ingredients. 
  • Athletes who are already taking separate creatine or pump products may find them redundant in this supplement.

Though this product is on the pricier end of the spectrum, you’re getting a wide range of ingredients in this mix. Along with a blend of BCAAs, you’re also getting pre-workout ingredients and creatine, so you won’t have to take three different products separately.

Best BCAA for Men

For men working to build muscle, a dose of BCAAs may help you pump longer and harder. This particular supplement provides eight grams of BCAAs and a dose of coconut water powder for hydration.

Huge Supplements Huge BCAA

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 can replenish as you go. Huge Supplements contains 8,000mg of BCAAs in a 2:1:1 ratio.

Plus, there’s an added dose of calcium, potassium, and sodium, as well as coconut water powder for hydration to make sure you’re hitting all your marks during and after your workout. It’s worth noting that this supplement only comes in two flavors — Kiwi Blueberry and Bomb Popsicle — though, so if you’re looking for flavor variety, you will not find it here.

  • Anyone who would prefer a BCAA supplement that’s just BCAAs — this product contains additional ingredients to supplement its leucine, isoleucine, and valine. 

Though BCAAs can be taken pre-workout, they can also be a part of a balanced intra-workout or post-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 electrolytes for a well-rounded beverage that can be taken before, during, or after exercise. 

Best Tasting BCAA

If you’re trying to sneak more BCAAs into your diet, it’s important that the vehicle you’re using to sneak them in actually tastes good. This product is one of the best-tasting BCAA blends we’ve tried. 

Transparent Labs BCAA Glutamine

Transparent Labs BCAA Glutamine comes in five tasty flavors — Sour Green Apple, Tropical Punch, Strawberry Lemonade, Blue Raspberry, and Orange. No matter which flavor you choose, this BCAA powder is entirely naturally flavored and sweetened. Transparent Labs dissolves well into water, and is intended to be sipped on during your workout as an intra-workout supplement. In addition to 8g of BCAAs, you’ll find 5g of glutamine and 1g of coconut water powder, which may help with even more muscle gain and hydration, respectively. Transparent Labs BCAA glutamine is a bit pricey, but the taste is worth it in our opinion.

IdealLean BCAA

Best BCAA Pills 

There are a lot of benefits to taking your BCAAs in pill form instead. For one, you can take them with you to the gym or on the road, which is great if you’re going for long periods between meals. For a no-nonsense BCAA pill, Optimum Nutrition BCAA pills are our go-to.

Optimum Nutrition BCAA Pills

Though some people choose to stay away from pills because they may not be as easily digested as a powdered mixture, they’re likely a more convenient option to get your BCAAs in than powder. Optimum Nutrition has been a mainstay in the supplements industry for decades, putting out consistently high-quality, straightforward products — and their BCAA pills are no different. 

The only ingredients you’ll find here are the BCAAs, of which each two-capsule serving provides 500mg of l-leucine, 250mg of l-isoleucine, and 250mg of l-valine. Other than that, it’s just the capsule ingredients (which do include gelatin, so this supplement is not vegan-friendly). These 2:1:1 caps are very competitively priced, especially since each container has 200 servings in it. Since these are capsules, if you want to vary the amount taken to be more or less depending on how hard your workout was, you can with ease.

If you want plain BCAAs but can't stomach their notorious taste, Optimum Nutrition's capsules are the perfect alternative. You'll get 500mg of leucine, 250mg of isoleucine, and 250mg of valine per two-capsule serving. 

Who Should Buy Optimum Nutrition BCAA Pills

  • Folks who are on the go often. If you’re on a lengthy trip, and airplane meals or truck stop snacks aren’t giving you the leucine you need, having BCAA pills in your backpack can be handy.
  • Anyone who doesn’t like carrying a shaker bottle around. No need to mix anything or carry around a bulky shaker cup with these pills.
  • Anyone who wants to avoid the artificial sweeteners that can be so common in these products. All you’re getting here is BCAAs and a gelatin capsule.

Who Shouldn’t Buy Optimum Nutrition BCAA Pills

  • People who are looking to consume some other ingredients to help with recovery or muscle building may want to look at more robust products on this list.
  • Anyone who doesn’t want to take six pills at a time for a three-gram dose (or more to reach a 10-gram dose). 
  • If you’re vegan, you’ll need to find a different option as these capsules do contain gelatin (which is an animal product).

Capsules are a handy way to get your BCAAs in on the go without a shaker bottle. Plus, everything is precisely measured out to make dosage easier to vary up or down, depending on your needs at the moment. When you don’t feel like chugging sweetened water, this is a fast, cheap, and convenient way to spike your amino acid intake. These BCAA pills from Optimum Nutrition are about as straightforward as they come, and we like them that way.

Best BCAA for Keto

Ketogenic diets are ultra low-carb and often relatively low in protein, so many supplements with branched-chain amino acids can 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. It contains five grams of BCAAs, which includes the desired 2:1:1 ratio of leucine to isoleucine to valine. It’s worth noting, however, that this is not the cheapest product on the market.

  • Alpha Amino happens to be soy-free, so it’s a solid choice 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.
  • Anyone who wants more than one flavor to choose from — this product only comes in Watermelon.

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.

When Should I Take BCAAs?

It’s best to take BCAAs before or during your workout, depending on which kind you are using. BCAAs are a great supplement to potentially help build muscle through muscle protein synthesis. Many BCAAs come in a pre-workout blend, some come in an intra-workout blend, and most general BCAA supplements will instruct you to consume them 20 to 30 minutes prior to working out. A few BCAA supplements will say that you can take them before, during, or after a workout, but as far as basic BCAA supplements go, they’re most effective if you take them pre-workout. (2

BCAAs can come in an intra-workout blend, and these blends are meant to be consumed specifically during exercise. For anyone who’s going hard at the gym, intra-workout BCAAs may be helpful in warding off fatigue. (3

How Much Do BCAAs Cost?

BCAAs can be a fairly expensive individual supplement. Container prices range from $20 to $50, but in order to know exactly how much you are getting for your money, you’ll want to look at the cost per serving of each product. To do so, you should weigh the overall cost against the number of servings in each container — you’ll likely find that BCAAs go for anywhere between $0.75 and $2.50 per serving. 

The price of your BCAAs will go up depending on the ingredients you’re getting and how convenient the supplement is to take. For example, Performance Lab BCAAs are likely a bit more expensive because they come in pill form, which makes them easy to take on the go. Pre-Kaged is also more expensive because these BCAAs come in the form of a pre-workout, which contains a number of other energy-boosting ingredients. 

BCAA supplements often come with vitamins and minerals mixed in as well, and these blends will be more expensive than basic blends that are mainly just BCAAs. 

How We Decide the Best BCAAs

There are several elements we looked at — and dozens of products — to land on this list of the best BCAAs. Here’s the list we referenced as we assessed these supplements’ efficacy.

Amino Acid Ratio

The standard formulation for these products is two or three grams of leucine for every gram of isoleucine and valine (2:1:1). Although some products have many times more leucine, this hasn’t been shown to be more successful than the “standard” ratios. We looked for products with this standard 2:1:1 ratio when formulating this list. 

Ergogenic Effects

In addition to BCAAs, many products — including our number one pick — include ergogenic aids or ingredients linked to improved performance. These can include citrulline (related to improved circulation), beta-alanine (endurance), and caffeine (explosive power). We’ve included picks on this list that incorporate these ingredients, as well as picks that don’t. With the variety of options, those who are avoiding certain ingredients, like caffeine, shouldn’t have a problem finding a pick that works for them. 

Lipolytic Effect

Some of the BCAA products we highlighted include 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. We’ve included BCAAs both with and without these ingredients on this list to suit the variety of needs customers may have. 

Micronutrients

Many BCAAs include extra Vitamin B6, which may help with muscle retention and which the body appears to lose during intense exercise. Some BCAAs have other B vitamins in addition to more micronutrients — like Vitamin C, which may help to limit oxidative damage during exercise, and sodium, which may help with hydration. If you’re keen on having added micronutrients in your BCAA supplement, we have plenty of options for you on this list. And if you’d rather skip the added vitamins and minerals and pay a little less for your BCAAs, you’ll also find those products in this list. 

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. (4)(5)(6) They’ve even been linked to increased fat loss and quicker reaction times. (7)

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 BCAAs?

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.

Leucine 

Perhaps the most highly prized of all the amino acids, leucine has the closest link with boosting muscle protein synthesis, which occurs when protein in your body helps to repair the muscles damaged during exercise. While your total calories are essential for muscle growth and muscle retention, muscle protein synthesis is a vital part of the puzzle. (8)

Isoleucine

Used in the biosynthesis of proteins, this branched-chain amino acid may help prevent muscle breakdown, and promote fat burning. (9)

Valine

Another BCAA, valine, has some links to endurance and focus. Interestingly, if you have difficulty digesting it and there’s more of it in the blood, this could actually be a sign of insulin resistance, a risk factor for diabetes and other conditions. (10) (11)

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

Glutamine 

A conditionally essential amino acid (remember amino acids are building blocks of protein), glutamine is enormously popular in supplements because it has some links to muscle gain. 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. (12)

Beta-Alanine

A ubiquitous addition to pre-workouts, one-and-a-half to four grams of this stuff has shown to improve endurance and possibly hypertrophy. It’s possible that it also has some anti-aging effects, as it can increase the amount of carnosine (an antioxidant) in the body. (13)

Citrulline Malate 

An amino acid that’s prevalent in watermelons (along with legumes and organ meats), citrulline appears to improve nitric oxide metabolism, which can lead to better circulation and blood flow. In workouts, this can translate to better endurance and power output. It’s also a common ingredient in erectile dysfunction supplements. (14)

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. (15)

Vitamin C 

This vitamin may reduce cell damage that occurs during exercise. It’s a powerful antioxidant, which can be helpful for immune support. (16

B Vitamins 

The eight B vitamins may help increase one’s energy without jitters or unwanted sleep loss. They may also help with brain function and cell health. (2)

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 adding these to your daily regimen. Always speak with your physician before undertaking a new supplement regimen. Once you do, read on for a few pro tips to consider on 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 potentially 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 and muscle gain. All in all, to reap the most benefit from your BCAAs, make sure your daily nutrition and caloric intake is on track first and foremost.

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 as necessary. Consider your diet in full before deciding if a BCAA supplement is right for you. 

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 “high quality” supplement, but we think we’ve put together the most comprehensive guide to aid in picking the perfect BCAA supplement to match your goals. 

FAQs

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.
