BCAAs, or branched-chain amino acids, are three essential amino acids, commonly taken to help boost muscle growth and help improve exercise performance. They may also help ease exercise fatigue and support weight loss. BCAAs are considered “essential” amino acids because your body cannot make them on its own. That’s why it’s important to get them from supplements or the foods you eat.
We’ve researched the most popular BCAA supplements extensively to see if they really do live up to the hype. In this thorough BCAA supplement review, we’re going to take a closer look at the highest-rated BCAA supplements to see if they can help provide you with the boost you’re looking for.
Transparent Labs CoreSeries BCAA Glutamine
When choosing a BCAA supplement, it’s important to consider the right ratio of Isoleucine and valine (250mg) to leucine (500mg) for proper metabolism and muscle support. Transparent Labs’ CoreSeries BCAA Glutamine not only delivers this precise ratio but also includes glutamine in the formula. Glutamine is an amino acid that is naturally produced by the body and is found extensively in muscles. Combining the two helps to both nourish your muscles and supports muscle growth and endurance.

Dymatize All9 Amino
Dymatize All9 Amino (known simply as ALL9) bills itself as a “full spectrum amino acid supplement that contains both BCAAs and EAAs (Essential Amino Acids). The nine EAAs provided by ALL9 are those that the body can’t produce on its own. Because you can mix it with water, you can take ALL9 pre or post workout, or any time you want. This makes it incredibly convenient if you have a busy schedule but still want to give your body everything it needs to help support muscle health and growth.
- Contains both BCAAs and EAAs
- Available in five unique flavors
- No artificial colors
- No sugar
- Includes vitamins B6, B12 and C

ALL9 is great for those who want a complete spectrum amino acid supplement that goes beyond BCAAs.

However, there are several flavor varieties to choose from — some quite unique from the competition, like Cola Lime Twist. Those who are sensitive to phenylalanine should not take this supplement, as l-phenylalanine is one of the essential amino acids in the mixture. Overall a solid buy for anyone who wants to make sure they’re getting all of the amino acids their body needs for proper protein synthesis and muscle growth.

What to Look for in a Good BCAA Supplement
When it comes to buying a BCAA supplement, there are certain questions you should ask yourself in order to better gauge the quality and efficacy of the supplement you’re considering.
What is the Overall Quality of the Product?
Check the ingredients label. What’s in it and how does it work? Some BCAA supplements are made with synergistic blends of ingredients that support each other and improve each other’s function better than if they were separate. Read the label carefully. Some lower quality BCAA supplements contain “proprietary blends” which don’t go into detail about how much of each BCAA they actually contain, and may have more fillers than the actual amino acids you need.
What is the Brand’s Reputation and Quality?
There are hundreds of BCAA supplements out there in every shape, form and color. But it’s important to know what you’re actually putting into your body. What about the brand behind the supplement? Is it well-known and trusted? Or did it seem to crop up overnight and gain a sudden influx of five-star reviews? If you’re not sure, ask. How long have they been taking it? Did it make them feel any different? If so, how?
What Do Users Say About It’s Effectiveness?
Everyone has their preferred BCAA supplement routine. Some prefer to drink it before a workout while others prefer during or after. You may notice that the effectiveness of the BCAA supplement differs depending on when you take it, so try out different timeframes and see how your body responds accordingly. Every person is different and everybody handles supplementation differently.
When Should It Be Taken?
Some BCAA supplements include stimulants like caffeine that help improve focus and energy and are better taken in the morning. Others are more effective after a workout. Consult the manufacturer’s directions to better understand the optimal time to take your supplement.
Should It Be Taken with Food/Water?
Some BCAA supplements work better with food and have less digestive upsets as a result. Others should be taken on an empty stomach. Everyone reacts differently to supplements according to their own preferences. Nobody knows your body like you do, so if you take a supplement on an empty stomach and have digestive upset, it may be worth trying it with a light meal next time to see if the feeling subsides.
What Type of Ingredients Does it Contain?
Every supplement is different and it’s important to note not only what the ingredients are, but how they work together. Like all supplements, many BCAA mixes contain other ingredients that work together synergistically with them, including:
Grape Seed Extract – A potent antioxidant that may help prevent cell damage during exercise .
Citrulline Malate – An organic salt made up of the non-essential amino acid citrulline. It may help improve exercise performance, particularly during resistance training.
Creatine – Creatine is naturally found in muscle cells and as a supplement, is very popular among weight lifters and bodybuilders for its effects on endurance and strength /
Carnitine – Carnitine affects the body’s metabolism and some studies show that it may have an effect on weight loss as well as brain function. 
Panax Ginseng – A leaf historically used in traditional Chinese medicine. Some studies have demonstrated that it lowers the body’s inflammatory immune response as well as helps decrease muscle damage due to exertion.
Green Tea Extract – A potent antioxidant that can help reduce cell damage as well as lessen muscle fatigue 
Bioperine – Made from an extract of black pepper, Bioperine is a proprietary and patented form of the extract which has been shown in studies to help increase the bioavailability of substances in the body. Bioavailability is simply the amount of a substance that can be used by the body at any one time. The higher the availability, the more readily usable the substance is. Many of the best supplements contain BioPerines to allow the body ample time to take advantage of the substance rather than simply dumping it all into the bloodstream and seeing the majority of it go to waste.
Now, just because a particular substance doesn’t have these particular ingredients, doesn’t necessarily mean that it’s inferior to the others. However, when looking for a BCAA supplement, pay special attention to supplements that have most or all of these ingredients, as it shows that the manufacturer has done their research in combining the best possible ingredients with substantial scientific research behind them.
Does it Include Stimulants?
Some BCAA supplements include caffeine to help promote alertness and focus. In general, a typical cup of coffee has around 95 mg of caffeine, so keep the caffeine amount in mind when you’re measuring the serving size of your BCAA supplement.
How Much Value Do You Get From It? What is the Price Per Serving?
Small serving sizes encourage you to buy more, especially if you use a BCAA supplement every day. Consider the price per serving and the results you’re getting from it. Everyone’s body reacts differently, so you’ll want to judge for yourself if the price is worth it.
Has Any Trusted Third-Party Testing Been Conducted On It? Does it Adhere to FDA Standards?
You want to be confident that whatever you’re putting into your body is made up of quality ingredients. Look for supplements that are made in facilities that adhere to cGMPs or Current Good Manufacturing Processes. This means that they’ve been certified by the FDA to follow or exceed the correct procedures to ensure safety and quality. There are many other third-party seals and certifications to consider, including certifying that a mix is free from banned substances, that it’s gluten-free or vegan-friendly, and more.
How Easy Is It to Buy and Take?
Making a BCAA supplement part of your routine revolves around how easy it is to buy and take. If you dread the taste or the effects you feel when you take it, it’s a sure bet that more of it will end up in the trash than in your body. Consider choosing a supplement that’s convenient and gives you the results you’re looking for. Everybody is different and responds differently, so it’s not a bad idea to try out several of the top brands and see which one works the best for your individual needs and goals.
