Once a niche athletic supplement, branched-chain amino acids (BCAAs) have exploded in popularity as a means to potentially improve muscle retention, endurance, and focus during workouts. (5) Now as synonymous with supplementation as the best protein powders and pre-workouts, the best BCAA supplements offer key benefits encased in flavorful profiles at affordable costs.
Given the landscape of the category, finding a proper BCAA powder or capsule for your training needs can be difficult at times. To lend a helping hand, we’ve called on our team of experts and diehard fitness enthusiasts to test over 20 BCAA supplements from top brands, examining each profile through the lens of our supplement testing methodology.
This methodology includes, at a high level, having our experts look at the formulas to ensure that safe, research-backed ingredients are used. We also prioritize products that are third-party tested. In addition, our testing team evaluates their own personal experiences using these products, weighing factors like taste, texture, efficacy, price, and convenience to provide real-world insights around the day-to-day experience with these supplements.
We also consulted with Dr. Jennie Stanford, M.D. and Chelsea Rae Bourgeois, MS, RDN, LD to make sure we understood the purpose of BCAA supplements and how to best analyze them. Each BCAA supplement chosen for this roundup was rated in major areas relative to the category, including:
- Amino Acid Ratio: How are the BCAAs ratioed within the given formulation? Does the split across the leucine, isoleucine, and valine counts support effective performance?
- Listed Ingredients: Does the product contain BCAAs independently, or are there other additives to help fuel progress in other areas of training?
- Taste: Do the available flavors warrant continued use of the supplement? Is there enough variety to help defend against flavor fatigue?
- Solubility: How well do these products blend in a shaker bottle?
- Value: Does the listed cost per serving align with the results and effectiveness of the supplement, itself?
The BarBend team has helped connect over 1.6 million athletes with high-quality nutritional supplements to give them the boost they desire when it comes to health and wellness. If you’re searching for a new BCAA powder to add to your regular routine, we’re confident the following details can help you shake up your supplementation (in a good way).

Best BCAA Powder Overall: Transparent Labs BCAA Glutamine
Why We Like It
With an outstanding formulation and numerous flavor options available, Transparent Labs BCAA Glutamine earns our top pick for the best BCAA supplement. We love that this product is made without artificial flavors, dyes, and sweeteners.
According to Chelsea Rae Bourgeois, RDN, this formula contains the ideal BCAA ratio.“The 2:1:1 ratio is backed by research and the added glutamine offers some additional benefits,” she says, rating the formulation a 4.5 out of 5. “While stevia is fine for most, some can’t tolerate it or don’t like the taste, which is good to keep in mind.”
Each single-scoop serving offers a whopping 8 grams of BCAAs. Transparent Labs also added coconut water powder, which is rich in electrolytes for hydration, and a high 5,000-milligram dose of l-glutamine to potentially reduce muscle soreness following a workout (making it one of the best glutamine supplements, as well). (12) This supplement also packs over 1,000% of your daily vitamin C needs to support a strong immune system. (16)
A 30-serving tub costs around $39.99, which equates to roughly $1.33 per serving. This cost is more expensive than many other products you’ll find on this list. One reason the cost is so high, we assume, is because Transparent Labs BCAA Glutamine is third-party tested. Third-party testing ensures you can trust that what’s on the label is what you’ll find in the actual formulation.
Regarding taste, our testers and other verified reviewers have mixed opinions. Our certified health coach tried the Strawberry Lemonade and rated it a 3 out of 5. “I found an initial taste that was bitter, and this particular flavor had a funky aftertaste,” she notes. Some tastier options for athletes may be Cellucor Alpha Amino and Nutricost BCAA.
Transparent Labs dissolves exceptionally well in water, with our tester reporting no issues. “There weren’t any leftover powder clumps; it completely dissolved,” she says, giving it a perfect 5 out of 5 for solubility.
Good for: Those wanting a robust formulation that’s third-party tested and free of artificial additives.
Not good for: Those looking for a low-cost, budget-friendly BCAA option.

Best BCAAs for Endurance Athletes: 1st Phorm BCAAs
Best Budget BCAA: Nutricost BCAA
Why We Like It
It’s not necessary to spend tons of money on supplements each month, especially for athletes with a tight budget. If you’re searching for an affordable BCAA supplement that won’t break the bank, our team recommends Nutricost BCAA Powder. This product starts at roughly $0.25 per serving, earning a 5-out-of-5 rating for overall value. For additional discounts, you can subscribe to recurring deliveries.
“These BCAAs score a 4 out of 5 for their formulation,” Chelsea Rae Bourgeois, RDN, says. “They have a clinically dosed ratio of leucine, isoleucine, and valine, but they also contain artificial ingredients like sucralose, which may cause GI upset.” We also note that Nutricost BCAAs are just BCAAs, so don’t expect any added compounds to support weight loss, boosted energy, or other goals.
After taking this product three times per week, and mixing it with water, our expert product tester Kate Meier, CPT, didn’t notice any immediate effects. However, she didn’t experience any negative effects, either.
“I tried the unflavored option and it wasn’t completely flavorless,” Meier said. “However, I’d still rate the flavor a 5 out of 5 because it mixes so well with other drinks. When you mix it with some of the best pre-workout supplements or a sports drink, it completely masks the BCAA powder.”
We really liked the product’s solubility, too, rating this category a solid 5 out of 5. Meier mixed this product in both a shaker cup as well as with a common glass and spoon. “Either way that I mixed, the water was a little murky and there were some small grains in the texture,” she said. “But in just a minute or two, it completely dissolved.” Of course, though, for those less enthused about having a shaker bottle handy for proper supplementation, we recommend looking at pilled or capsuled supplements like Crazy Muscle BCAA Pills.
Good for: Individuals looking for a budget-friendly BCAA powder with costs per serving starting below $0.30.
Not good for: Those looking to avoid artificial sweeteners.
Best BCAA for Men: Transparent Labs Intra
Why We Like It
BCAA supplements aren’t necessarily gender-specific, but if you want a supplement with BCAAs that can support you through a workout, Transparent Labs Intra could be a good fit. Our tester, a triathlete and a certified sports nutrition coach, used Intra on multiple occasions.
“While I can’t say this enhanced my performance, specifically, I can say that the inclusion of electrolytes and essential amino acids is exactly what I look for in a workout supplement,” they said.
Offering the ideal 2:1:1 ratio of BCAAs, this intra-workout supplement is ideal for those wanting amino acids along with other ingredients that are proven to reduce muscle fatigue, improve endurance, support muscle growth, and promote endurance. (17)(18)
“TL Intra gets a 4.25 out of 5,” according to Chelsea Rae Bourgeois, RDN. “It is packed with powerful ingredients, but some compounds are patented and don’t share the breakdown of ingredients included.” She also likes that the formula contains all nine essential amino acids. Essential amino acids are those that the body doesn’t make on its own, so we have to consume them through food or supplements. (19)
There are two flavors of Intra: Strawberry Lemonade and Blue Raspberry. Our tester awarded Blue Raspberry a 4 out of 5 for taste, stating that it’s almost too sweet. “I recommend mixing it with more water than the instructions indicate,” she adds. “When I did that, the flavor wasn’t quite so strong, and I enjoyed it more.”
Furthermore, our tester noted that the solubility is alright, as long as you shake before drinking. If you don’t shake between sips, the powder tends to settle toward the bottom. We rate Intra at 3 out of 5 for the category and recommend powders like Nutricost BCAA or Transparent Labs BCAA Glutamine for better blending protocols.
Intra costs around $1.50 per serving, which earns it a 3-out-of-5 rating from our testers. That said, you can utilize Transparent Labs discount codes for better deals, or use the brand’s ‘Subscribe & Save’ service for lower purchase totals and free shipping on repeat orders.
Good for: Athletes wanting a quality intra-workout supplement to help bolster endurance and sustain hydration levels.
Not good for: Those looking for an unflavored option.
Best BCAAs for Muscle Growth: Momentous Vital Aminos
Why We Like It
If you’re focused on muscle growth, it’s crucial to eat enough calories and protein throughout the day. When it comes to supplements like the best creatine supplements and BCAAs, you might want something that supports athletic performance and offers quality ingredients. Momentous Vital Aminos contains a scientifically backed dosage of all nine essential amino acids, which are key for building, maintaining, and repairing lean muscle mass. (19)
“This product is great for me since I primarily eat a vegetarian diet and I’m trying to keep my body in top shape for volleyball and climbing,” says our tester, certified personal trainer Rosie Borchert.
As an additional benefit, Momentous Vital Aminos include l-tyrosine, which has been shown to improve cognitive flexibility and enhance your ability to switch between tasks without losing focus. (1)
BCAAs are known to support muscle recovery, but they can also help increase muscle growth. The BCAA leucine, for example, is key for building muscle as it stimulates muscle protein synthesis. (4)(17) What’s more, there’s added doses of calcium, potassium, and sodium to help maintain hydration. However, the ingredient doses are lacking.
“This formula gets a 2.5 out of 5 in my book,” Chelsea Rae Bourgeois, RDN, says. “The lack of research gives me pause, and to top it off, the amount of each ingredient really leaves you wanting more. Adding small portions of a few specific foods can give you more than you get in this formulation — and at a lower cost.”
This product only comes in Tropical Punch. However, our tester really likes the taste, giving the flavor a 5-out-of-5 rating. “Mixed with a glass of water, the flavor is really light and refreshing,” says Borchert. For flavor hounds, though, it may be best to opt for the likes of Nutricost BCAAs or 1st Phorm BCAAs for a larger variety of available tastes.
A 30-serving bag of Momentous Vital Aminos costs around $45.95, which is about $1.53 per serving. Unfortunately, this is one of the most expensive products on our list, earning a 3 out of 5 for cost.
Good for: People focused on building muscle that want to supplement with BCAAs.
Not good for: Those looking for a wide range of flavor options.
Best Vegan BCAAs: Naked Nutrition Naked BCAAs
Best BCAAs for Recovery: MyProtein Essential BCAA 2:1:1
Why We Like It
One of the most established benefits of BCAA supplements is their ability to support efficient muscle recovery. (4)(17)(19) If you’re looking to make this a priority within your regimen, we recommend Essential BCAA 2:1:1 Powder from MyProtein. This formulation packs in 4 grams of branched-chain amino acids per three-scoop serving in an ideal 2:1:1 ratio for muscle protein synthesis and easier recuperation post-training.
As a certified nutrition coach, I appreciate the clear supplement facts on the back of the packaging — you can quickly digest what’s included in the makeup. However, I rate the formulation at 3.75 out of 5 given the presence of sucralose in a majority of the flavored options. “Sucralose can cause GI distress in some athletes, so it may be best to steer clear,” notes Chelsea Rae Bourgeois, registered dietitian nutritionist and BarBend expert reviewer. More natural, synthetic-free options include Transparent Labs BCAA Glutamine and Momentous Vital Aminos.
As far as taste is concerned, we score MyProtein Essential BCAA at 4 out of 5 given the range of flavor options available, including an Unflavored pick that can be added to pre-workout or even some of the best post-workout supplements without altering the flavor profile excessively. I’ve previously had the Peach Rings option, too, and do admire the accuracy of the flavor titles — it tastes like one of my favorite gummy treats. While some may find this BCAA powder to be excessively sweet given the sucralose content, I do feel that many would enjoy the makeup, overall.
MyProtein Essential BCAA is available in multiple container sizes with costs starting at roughly $0.73 per serving. I always try to seek out supplements available in multiple tub (in this case, bag) sizes, as it opens the door for bulk orders at a lower price point. As such, we rate the value at 4 out of 5. A word of caution, though — bagged containers, while efficient and space-saving, can lead to some mess when digging out your servings.
Good for: Individuals with dedicated recovery regimens for improved muscle retention and fewer bouts of muscle soreness.
Not good for: Those looking for a vegan option.
How We Tested and Chose the Best BCAAs
The BarBend team is composed of competitive athletes, certified personal trainers, nutrition coaches, and lifelong fitness enthusiasts. To determine the best BCAA supplements available today, we tested 26 different products from high-quality brands, using our supplement testing methodology as guidance in rating each silhouette in a range of categories. Ratings were scored on a scale of 1 (lowest) to 5 (highest) in categories such as the following:
- Amino Acid Ratio: We prioritize products with a 2:1:1 ratio of BCAAs. The standard formulation for these products is 2 or 3 grams of leucine for every gram of isoleucine and valine. Products with lower ratios may not be as effective.
- Third-Party Testing: We favor products with third-party testing from independent labs. Third-party testing verifies label accuracy, so you know the ingredients on the label match what’s actually in the container.
- Ergogenic Effects: Alongside BCAAs, many products include ergogenic aids or ingredients linked to enhanced exercise performance. These can include citrulline, beta-alanine, and caffeine. We included picks on this list that incorporate these additional ingredients, as well as products that don’t.
- Taste: Although taste is subjective, we assign a rating based on whether a product is true to its flavor name. We share our thoughts on the sweetness, aftertaste, and bitterness of various products.
- Solubility: We favor products that dissolve easily without clumping or leftover floaties.

Benefits of BCAAs
BCAAs are the building blocks of protein, and when you consume complete protein sources like chicken, beef, fish, or whey protein powder, you are consuming BCAAs. If your diet is rich in high-quality protein sources, chances are you’re already getting the benefits of BCAAs. Accordingly, BCAA supplements aren’t necessarily a must-have, but they may support muscle growth and improve athletic performance. Here are a few benefits you may see with consistent BCAA use:
- Improved Muscle Mass: Leucine, one of the three BCAAs, plays a role in stimulating muscle protein synthesis, which is needed to build muscle. (17) The recommended “threshold” for leucine intake is often noted as 2 to 3 grams per day for maximized muscle-building potential. (17)
- Improved Performance: BCAA supplementation may be able to help improve your performance by preventing fatigue while you train. (3)(6)
- Improved Reaction Time: Although more firm research is needed, BCAA supplements may be able to help improve your reaction time during athletic performance. (7)
Potential Negatives of BCAAs
Studies report that regular BCAA consumption has shown to cause no adverse effects. (23) However, taking BCAAs featuring other ingredients like artificial sweeteners or known allergens can lead to gastrointestinal discomfort, bloating, and other unwanted symptoms. For BCAAs containing caffeine and other stimulants, Dr. Raj Dasgupta, MD states, “Athletes with known sensitivities to the effects of caffeine may experience side effects such as anxiety, insomnia, or headaches, even with lower doses below the FDA’s 400-milligram daily recommendation.” (24)
There’s also concerns over BCAAs and their relationship to insulin resistance. “The relationship between BCAAs and insulin resistance is complex, as BCAAs cause the liver, adipose tissue, and skeletal muscles to have different metabolic responses,“ says Dr. Jennie Sanford, MD. “BCAAs do not cause systemic insulin resistance, but when they are metabolized poorly, this can be a sign of underlying insulin resistance that needs to be addressed.“
As with every supplement — from the best multivitamins to proteins, pre-workouts, and beyond — it’s always advisable to take your personal sensitivities into question prior to purchase. You can also speak to your personal healthcare provider if you’re looking for more detailed information on which ingredients and dosages align with your personal needs and wants.
What to Consider Before Buying BCAAs
“For people who regularly eat animal proteins, your diet probably includes sufficient amounts of BCAAs,” notes Dr. Jennie Stanford, MD. “However, amino acids are needed for a number of physiologic functions, and when you don’t have enough circulating amino acids, your body will break down muscle tissue to release them. So, for extended periods without consuming protein or even working out in a fasting state, BCAAs can help maintain lean muscle mass.”
Before purchasing a BCAA supplement, you may want to consider a few important factors. As BCAA supplements can vary substantially, you’ll want to consider ingredients, dosages, formulation, price, and the necessity of BCAAs before making a decision. We detail each of these more below:
Ingredient List
The ingredient lists on BCAA supplements can vary drastically from one supplement to another. You’ll want to consider what you’re looking for in a BCAA supplement and what you hope the outcome of taking one will be. If you’re looking strictly for BCAAs, you may want to opt for a simple formulation with a minimalist ingredient list. If you’re looking for BCAAs to be a part of your supplement regimen, but not the entirety of it, you may want to choose one with a solid dose of BCAAs as well as other ingredients, like glutamine, citrulline, or electrolytes.
For those looking to combine BCAAs with electrolytes, Dr. Raj Dasgupta, MD has an important note to consider: “It’s important to remember that sodium is the most abundant electrolyte lost in sweat, so if you’re looking for a supplement with added electrolytes to fuel your extensive training in intense conditions, be sure to confirm that sodium replenishment is feasibly achievable with the formulation of choice.”
Dosages
You’ll also want to consider how many grams of BCAAs each product offers. The recommended breakdown for BCAAs is a 2:1:1 ratio of leucine to isoleucine to valine for best potential effect. (18) Many supplements on the market have 4 grams in total of BCAAs, but you will find some supplements on this list that contain up to 8 grams, as well. Some prefer to opt for a higher amount of BCAAs for effectiveness or potential recovery benefits.
Formulation
Are you looking for straight BCAAs, or do you want something more robust? More complex formulations will often include BCAAs with several other ingredients that offer exercise-enhancing benefits. BCAAs are also commonly found in pre-workout supplements and are naturally occurring in the best protein powders. Some people prefer to take straight BCAAs as an additional supplement in their stack. Others prefer to include them wrapped up in another supplement, which can cut down on the number of supplements they’re taking.
You’ll also want to consider whether you want a flavored powder, unflavored powder, or a pill formulation. Some people enjoy the taste of sweet, tangy, or fruity supplements, while others prefer pills for a convenient on-the-go supplement for the gym or while traveling. There is no wrong answer, just the answer that best suits your lifestyle.
Price
Many supplements can be really helpful additions to your supplement lineup and may help you achieve your goals more efficiently, but they shouldn’t empty your bank account. Your budget will be a major consideration when you’re picking out your perfect BCAA supplement. That’s why we provided options for every budget.
Third-Party Testing
You should prioritize brands that are fully transparent about the ingredients in their supplements. The most reputable brands will typically run third-party testing to show that their products are safe and effective. Essentially, the third-party is an independent, external organization that evaluates a product’s makeup to ensure that what’s on the label is what’s in the product. Some organizations that you might see perform third-party testing include NSF, Informed Choice, Informed Sport, Banned Substance Control Group, and more.
What are Amino Acids?
In the simplest of terms, amino acids are molecules that form proteins within the body. In total, there are 20 amino acids, and nine of which are labeled as “essential” meaning the body cannot produce them internally, so they must be consumed through the diet.
Debating between BCAAs versus EAAs comes down to the molecular structure of the amino acids themselves, since BCAAs are EAAs, in theory. The distinguishing factor, as the name suggests, is the branched-chain structure of the molecules that make up leucine, isoleucine, and valine — the three BCAAs. The remaining EAAs include histidine, methionine, threonine, lysine, phenylalanine, and tryptophan.
What’s In Your BCAAs?
We know that supplement labels 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: Leucine has the closest link with boosting muscle protein synthesis, as it activates this process. 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 plays a role in muscle metabolism, as it may help prevent muscle breakdown and promote fat burning. (9)
- Valine: This has some links to endurance and focus. Interestingly, if you have difficulty digesting it, and it accumulates in the blood, this could indicate insulin resistance, a risk factor for diabetes and other conditions. (10) (11)
- Glutamine: Glutamine may help reduce delayed onset muscle soreness (DOMS) following a workout. (12) It also has some links to muscle gain, but most research has only seen this among people whose bodies are in physical trauma — it hasn’t translated to gains for gym-goers. (12)
- Beta Alanine: Found in pre-workouts, 1.5 to 4 grams has been shown to improve endurance and possibly aid in muscle 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: Citrulline is a nitric oxide booster, 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 plus L-Tartrate: These are linked to longevity, as they may improve mitochondrial function, and they could also help retain lean muscle mass and enhance aerobic output. (15)
- Vitamin C: Vitamin C may reduce cell damage from free radicals that occur during exercise. It’s a powerful antioxidant, which can be helpful for immune support. (16)
- B Vitamins: The eight B vitamins play a role in energy metabolism, the process that converts protein, carbs, and fat into energy. They may also help with brain function and cell health. (2)
BCAA Supplements 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.
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 an 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.
What is the best BCAA supplement?
While there are a wide variety of BCAA supplements that are great, our favorite is Transparent Labs BCAA Glutamine. It contains 8,000 milligrams of BCAAs, and we like the addition of beneficial vitamin C.
When should I take BCAAs?
It’s best to take BCAAs before or during your workout, depending on which kind you are using. 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 probably most effective if you take them pre-workout. (2) For anyone who’s going hard at the gym, intra-workout BCAAs may be helpful in warding off fatigue. (3)
Do BCAA supplements actually help build muscle?
BCAAs can help support muscle growth and improve athletic performance. They can also help prevent muscle fatigue while training, which can indirectly help you build muscle. However, if you’re eating plenty of protein and calories, taking BCAA supplements around a workout probably won’t have much benefit.
What’s the difference between BCAA and EAA supplements?
EAA stands for Essential Amino Acids, which are comprised of the nine amino acids essential to humans: phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine. BCAAs (Branched-Chain Amino Acids) are made up of leucine, isoleucine and valine, or essential amino acids that are grouped together because they have a slightly different chemical structure than the others. Essentially, BCAA supplements focus on these three amino acids, but can contain others.
