The importance of working out a couple of times a week is quite clear. Apart from allowing you to stay fit and toned, a good workout regime will release you of any negative energy and improve your mental health. The best thing about working out is that you can always switch it up and introduce new exercises, or make changes to your regime.

Whether it is gym, home workouts, swimming or team sports that you enjoy, with a balanced diet and sleep routine you are sure to achieve your goal. If it is to build muscle, then supplements can give you a helping hand. As you know, proteins are essential for muscle growth, and while you should get all the amino acids from the food you eat, taking BCAAs in moderation will not hurt you or your body.

If you are serious about your working out and achieving the best results, we have prepared a list of the three best BCAAs for muscle growth. So, what are you waiting for? Let's jump straight in and see what these products have to offer you.

Scivation Xtend Bcaa Powder


Best BCAAs for Muscle Growth Reviews

1. Optimum Nutrition Instantized BCAA Capsules

If you enjoy buying from trusted brands and you want to get only the best supplements, these Optimum Nutrition BCAA capsules are the perfect choice for you. While somewhat pricier than its competitors, one pack is sure to last you for a few months!


There are a number of reasons why you may want to take BCAA capsules. Building muscle and recovery are the main two, and you can be sure that with this product, success will be guaranteed (with a good diet and sleeping regime, of course). Coming from a brand that has been on the bodybuilding market for over a few decades, these capsules come in 60, 200, and 400 packs, with a regular serving being two capsules of 1000 mg. These capsules consist of the perfect 2:1:1 ratio featuring leucine, isoleucine, and valine. As we have mentioned above, you should be able to get these essential amino acids from red meat and other valuable protein sources, but as long as your regime diet is balanced, these few capsules can only do you good. While BCAAs do come in powder form as well, these are easy-to-swallow and ideal for anyone who is on the go.

The Optimum Nutrition capsules are compatible with any diet regime, whether you are on a keto, vegan or regular diet. Apart from the fact that it is not the best for those with a sensitive stomach, this product is worth your money!

2. Scivation Xtend BCAA Powder

If for whatever reason you are not a fan of BCAAs in a capsule, and you enjoy dissolving them in water, this Scivation product is a great choice for you. At an affordable price and with 30 servings per package one should last you at least a month!


While the brand is not as famous as Optimum Nutrition, we are still talking about a high-quality supplement that you can absolutely trust. What you should understand is that one serving of this powder is much stronger than the previously mentioned capsules. It contains 3.5 grams of Leucine, 2.5 grams of L-Glutamine and 1 gram of Citrulline Malate, which all serve their purpose when it comes to muscle recovery and growth. On top of all that, you are getting a 1140mg blend of electrolytes that will help you stay hydrated pre, during, and post-workout. The best thing about it is that unlike other BCAA powders, this one has great flavors. Our personal favorite? Blue raspberry ice! 

It dissolves in water without any issue, and you should expect it to do the trick within minutes of you consuming it. Yes, it is a bit too sweet for some, and may not be the best for those with digestive issues, but apart from that, it’s a product that you should definitely look into!

3. Optimum Nutrition Essential Amino Energy

Last but not least on our list of the best BCAAs, is another product from Optimum Nutrition. Coming in a powder form, it is easy to digest and has a great taste to it!


As we have mentioned above, there is not one reason to doubt the quality of Optimum Nutrition products. This one features a blend of various amino acids, along with 100mg of caffeine (per serving) that is extracted from coffee and green tea leaves. If you are in need of something to give you a kick and improve your focus while aiding in muscle growth and recovery, you are in the right place!

Coming in a number of flavors, of which our favorite is vanilla latte, it is a product worth your money. Yes, it may take some time to adapt to the strong smell of sweetness, but it only contains 1 g of sugar per serving. Overall, it is a great blend of amino acids and caffeine to keep you going throughout the day!

  • Very specific and sweet taste that may take some time to get used to

At the end of the day, it is hard to choose between the three highlighted products. Why? Because all of them seem to be worth the money and offer amazing results and benefits. While Scivation probably has the best formula per serving (for muscle recovery and growth), we love the Amino Energy product due to its caffeine content and ability to get you going, pre and post your workout. But at the end of the day, you need to make your selection based on your body's needs and your preferences. Only you know which will suit you best.
