Best BCAA Supplements

BCAA supplements (branched-chain amino acids) have exploded in popularity over the past few years. And for good reason.

The best BCAA supplements have shown to improve lean muscle growth, protein synthesis, muscle recovery, and overall muscle mass.

That’s why the market for BCAA supplements has exploded, leading to hundreds of brands launching BCAA powders, capsules, and pre-workout formulas.

BCAAs are essential amino acids that the body needs to build protein. Unlike other amino acids that are naturally produced in the body, branched-chain amino acids must be consumed through foods or supplements.

Branched-chain amino acids are made up of leucine, isoleucine, and valine. Each plays an important role in muscle growth and post-workout recovery.

Best BCAA Supplements

Our in-house team of health and nutrition experts have independently tested each of the BCAA supplements on our top 10 best BCAA supplement list.

We walk you through each BCAA supplement in detail, showing you how each BCAA product can help you in muscle building, preventing muscle breakdown (soreness), and supporting healthy muscle protein synthesis.

If you’d like to learn more facts about BCAA supplements before you buy, check out our detailed buying guide for more information.

BCAA Supplement Buying Guide

Now that we have completed our list of the best BCAA supplements, it’s time to turn our attention towards our BCAA supplements buying guide.

Here we walk you through how BCAA supplements work, the amino acids that are known as BCAAs, their benefits, and potential side effects.

We also share with you our top tips on BCAA supplementation so that you can maximize the impact of taking BCAA products on your muscle growth, protein synthesis, muscle recovery, and athletic performance.

Let’s dive in.

What Are BCAA Supplements?

BCAA supplements (also known as branched-chain amino acids) are dietary supplements that contain all three essential BCAAs. These include leucine, isoleucine, and valine.

There are twenty different types of amino acids in the body. Eleven of these amino acids are non-essential, meaning your body produces them naturally, whereas nine amino acids are known as essential, which means they must be consumed via food or supplements.

BCAAs are known as essential amino acids, and found in protein-rich foods like eggs, meat and dairy. They are called branched-chain amino acids thanks to their chemical structure.

Branched-chain amino acids promote a number of important benefits on athletic performance.

  • Muscle growth– BCAAs are the building blocks of protein, supporting muscle growth, while reducing muscle breakdown
  • Muscle recovery – BCAAs help to reduce muscle soreness post-workout, meaning your muscles can recover faster
  • Boost energy levels – BCAAs help to reduce fatigue during workouts, meaning you can exercise harder for longer
  • Prevent muscle breakdown – BCAAs increase muscle protein synthesis, helping to push the balance in favour of muscle growth, rather than muscle breakdown

How Do BCAA Supplements Work?

BCAA supplements work by increasing levels of BCAAs in your body, so that they are readily available before, during and after your workouts.

BCAA supplements contain the following amino acids:

  • Leucine – most of the best BCAA supplements contain a 2:1:1 ratio which is geared towards leucine. Leucine is the most important BCAA as it is a vital component in regulating protein synthesis, promoting skeletal muscle, metabolic rate, and tissue regeneration
  • Isoleucine – this important BCAA helps to synthesise proteins, help in producing hemoglobin, control blood sugar levels, and boost endurance and energy. These are all important factors in developing lean muscle mass
  • Valine – this final BCAA is important in enhancing energy and endurance, and in helping muscle tissue repair and recover. Valine has also shown to help lower blood sugar levels and increase levels of human growth hormone in the body

Taking BCAA supplements help to increase BCAA levels in the body. This will ensure that your muscles recover post-workout and that you have more energy and endurance during workouts.

Benefits Of BCAAs

There are a host of benefits that you will notice when supplementing with BCAAs. That is why the best athletes, power lifters and bodybuilders all stack BCAAs into their workout supplements.

Here is a breakdown of top benefits of BCAAs.

Promote Muscle Growth

One of the top benefits of BCAA supplementation is the effect that it has on muscle growth. Like whey protein, BCAAs help to facilitate protein synthesis. This means that after a heavy workout, BCAAs help to create pathways in your body that allow muscles to rebuild.

Studies have shown that those who consumed 5.6 grams of BCAAs post-workout (vs a control group) saw 22% great muscle protein synthesis.

With that said, always stack your BCAA supplement with whey protein, as the same study showed that those who took whey protein instead of BCAAs had the most dramatic uplifts in muscle growth.

Reduce Muscle Soreness

Another top benefit of BCAA supplementation is the impact that it has on muscle recovery. One of the main things that holds you back when carrying out a high-impact training program is muscle fatigue (or DOMS – delayed onset muscle soreness).

BCAAs help your muscles recover faster so that you are prepared for your next workout.

Accelerate Fat Loss

BCAA supplementation has been shown to help encourage fat oxidation during exercise. Particularly in those who who lead a glycogen-depleted diet.

One of the major goals of any serious training plan is to build muscle and accelerate fat loss. This is something that BCAA supplements can help with, as it promotes improved body composition and weight loss.

Increase Endurance

BCAAs have shown to improve “time-to-exhaustion” rates in glycogen depleted athletes during testing. That means that when you are carrying out intense physical exercise, BCAAs help you workout harder for longer.

In turn, this helps you to beat training plateaus, encouraging greater chances of muscle growth, and muscle recovery.

BCAA Supplementation Side Effects

The great thing about BCAA supplementation is that BCAAs do not promote any negative side effects if you stick to the correct dosage levels.

It is recommended that you consume between 5-12 grams of BCAAs per day, or between 10-20 grams if you are performing sustained vigorous exercise.

Most BCAA products contain between 5,000-10,000mg per serving which means you can safely consume 1-2 scoops of BCAA powder per day depending on the BCAA brand.

Despite BCAA supplements having no known side effects, people who take too many BCAAs per day have reported unwanted side effects like loss of coordination, headaches, fatigue (caused by increase insulin resistance) and feeling drowsy.

To avoid these side effects, always stick to the recommended dosage of BCAA supplementation.

Best BCAA Supplements Bottom Line

When it comes to building muscle, BCAA supplements offer you a great way to speed up muscle growth, fat loss, and muscle recovery.

This powerful essential amino acid helps to improve endurance during intense workouts, reduce muscle soreness post-workout, encourage greater muscle protein synthesis, and reduce the impact of DOMS.

If you are interested in adding BCAA supplements into your daily supplement routine, we’d advise doing so alongside a solid pre-workout formula, whey protein, and creatine powder.
