Amino acids are a critical part of any diet, but you might not be all that familiar with exactly what they do. They help you to grow new body tissue, build up existing tissue, break down food, and complete several other critical body functions.

If you want to build muscle or lose weight, you need to include amino acids in your diet. Supplements can be an easy way to make sure you are getting enough amino acids in your daily intake. As such, we’ve included a short list of the best amino acids for muscle growth and reviewed them.

Best Amino Acids for Muscle Growth: Brief Reviews

1. Primeval Labs EAA Max Elite Amino Formula

This product offers a profile that aims to provide your body with everything it needs for quick recovery while helping to enhance your muscle growth.


With the Primeval Labs EAA Max Elite Amino Formula, you will get a supplement that not only tastes good but also has a full amino acid profile and a full serving of 2:1:1 BCAAs. This means that you get the maximum amount of not only muscle growth but also muscle repair and recovery. You don’t have to spend as much time out of the gym from soreness or due to delayed recovery.

In addition, you don’t have to only enjoy this supplement solely on workout days. You can also use it when you aren’t planning on working out. This is because it also doubles as a way to keep getting your essential amino acids into your muscles, even if you aren’t lifting any weights that day.

While amino acids are crucial for muscle recovery, you should also be getting them regularly and with this product, you can sip it really whenever you want. Consuming it is not as difficult since it comes as gummy bears.

One drawback we found with this product is that some users claimed it upsets their stomach. That isn’t the case for everyone as reactions to the product are specific to the individual.

Ensuring you know the ingredients can potentially prevent any stomach issues. In many cases, supplements such as these may just contain something to which you have sensitivity and we just advise you double check to make sure that isn’t the case. The vast majority of users do not seem to have any issues.


  • Great flavors
  • Easy to consume


  • Can cause stomach issues


2. Alani Nu BCAA

The Alani Nu BCAA helps at lessening your soreness after a particularly tough workout, so you can limit your time out of the gym and get back at your normal routine quicker. You can take this product before or after your workout and some users choose to consume it during their lifting session.


This BCAA will keep you hydrated, which is crucial when you are particularly active. It will also help enhance your stamina and endurance. You might find that you are able to push yourself further than you anticipated, or further than you normally can.

As such, this is a great addition to your diet if you are trying to hit a new personal best or you are upping your routine and working toward a goal. It might just give you the boost you need.

This product does not contain any caffeine, so you should not have trouble falling asleep after taking this supplement, even during your evening workout. Ingredients include natural flavoring, citric acid, sucralose, silica, turmeric root extract, Acesulfame K, and beetroot extract. Additionally, this supplement is manufactured in a GMP compliant facility.

It is available in different flavors but some flavors are not always accurately represented. This is really the only drawback we could find.

With that said, the flavors taste really great, which is a huge benefit with this product. Many other BCAA products don’t taste very good and if you can’t get yourself to drink them, they aren’t really going to give you anything.


  • Great taste
  • Stimulant-free


  • Flavor descriptions not always accurate


3. eFlow Nutrition Endure

This product is ideal for any serious athlete with significant recovery needs. It helps to protect and preserve your existing muscle while helping you to gain increased strength and grow new muscle.


With this supplement, you will find that you have more stamina and endurance, while it helps enhance your muscle recovery following your challenging workouts. One of the best features of this product is that it will really help to reduce your soreness so that you can get back to working out pain-free in a shorter amount of time.

The formula is a combination of branched chain amino acids and essential amino acids. It contains nine amino acids for a mixture which helps you to grow new muscle mass while preserving the muscle you do have through recovery.

Unlike many other similar products on the market, this one has an enjoyable taste, so you won’t be trying to force yourself to drink it. There are also several flavor options from which you can choose including star blaze, rocket pop, snow cone, and gummy bear.

eFlow Nutrition Endure is made in the USA, is 3rd party tested, and GMP certified, so you can feel comfortable and safe purchasing it. There are no calories in this formula, and it does not contain any sugar or stimulants.

You can take it before, during, or after your training. There aren’t really any drawbacks to this product except that some users have felt the taste was a bit too sweet. This is personal preference, but the product can be diluted to your liking by just adding the right amount of water.


  • Great taste
  • Limits soreness


  • Can be very sweet for some
