Where to Get It

Performance Lab Sport BCAA Overview

Performance Lab Sport BCAA is a nutritional supplement designed to provide foundational support for muscle strength and development.

It’s made up of branched chain amino acids, also known as BCAAs. BCAAs include leucine, isoleucine and valine. In this case, they are offered in a 2:1:1 ratio of leucine:isoleucine:valine.

The BCAAs used in this product are fermented with sunflower lecithin. The manufacturer claims that this helps with bioavailability and digestive comfort – although this claim isn’t backed up by any specific studies.

There are no other ingredients, besides the 100% natural vegan plant-based capsules that the BCAA powder is contained in. This makes for a very simple supplement, ideal for those looking for high quality BCAAs and nothing else.

It’s also free of GMOs, gluten, soy, allergens, banned substances, and synthetic additives. It’s also made in a Good Manufacturing Practices (GMP) facility, by a reputable manufacturer.

The guide below will explain everything there is to know about this product, starting with the claimed benefits.

What Sport BCAA Claims to Do

Performance Lab Sport BCAA is designed for athletic nutritional support. The manufacturer claims that it can help with:

Muscle Growth

The claim is that this product helps to build new muscle, by accelerating the rate of protein synthesis. It also is supposed to help slow the rate of protein breakdown, helping to protect and maintain existing lean muscle mass.

There is evidence to support this claim. BCAAs do play an important role in protein synthesis, and are thought to activate key enzymes that are involved in the muscle building process. They are also considered to be the “building blocks” of protein and new muscle. Leucine in particular is thought to be the most beneficial for muscle protein production, which is why it’s the most abundant ingredient in this product. Several studies have found that taking BCAAs during intensive training resulted in increased muscle mass.

In short, branched chain amino acids do play an important role in protein synthesis and the building of new muscle tissue. Studies have found that taking BCAAs does have a positive effect on muscle growth rates. However, there’s no evidence to suggest that supplemental BCAAs offer any more benefit than the amino acids found naturally in protein-rich foods.

Muscle Soreness

The manufacturer claims that this product can help reduce muscle soreness and support faster recovery, by restoring the amino acids in muscle tissue that are depleted during exercise.

There is evidence to support this claim. In studies, participants who were given BCAA supplements after exercise experienced significantly less muscle soreness than the control group. Also, BCAAs appear to lower blood levels of two enzymes involved in muscle damage, potentially helping to protect against muscle damage in athletes.

BCAAs do appear to help fight muscle soreness, and potentially provide some protection against muscle damage. However, they do not affect everyone in the same way, so the results can vary.

Exercise Performance

The manufacturer claims that BCAAs can help to enhance both aerobic and anaerobic exercise performance, primarily by optimizing ATP energy production.

There is some evidence to support this claim. Several studies have found that athletes are able to perform for longer when given BCAAs. However, few studies have found a direct improvement in actual performance. More research is needed.


The manufacturer claims that Sport BCAA can help to extend athletic endurance during exercise.

There is evidence to support this claim. One study found that participants given BCAAs during exercise reported up to 15% less fatigue. Another study saw participants who were given BCAAs exercise for 17% longer than the control group, before reaching exhaustion. BCAAs can also reduce the production of serotonin in your brain during exercise, which further helps to reduce fatigue.

Most studies have concluded that branched chain amino acids do help to extend exercise endurance. The evidence is more mixed when it comes to actually improving performance.

What’s In It

One serving of Performance Lab Sport BCAA contains:

  • 3g instantized branched chain amino acids, fermented from sunflower lecithin
    • 1,500mg L-leucine
    • 750mg L-isoleucine
    • 750mg L-valine

L-leucine Leucine is considered the primary BCAA because it appears to offer the most benefit. It’s thought to be particularly important in the building of new muscle proteins.

L-isoleucineIsoleucine is another of the three branched chain amino acids. It’s thought to play an important role in the regulation of energy levels.

L-valineValine is the third, and least important, BCAA. It’s thought to offer the fewest benefits individually, but appears to work synergistically with the other branched chain aminos.

For Best Results

For best results, this product should be used in combination with a healthy diet and frequent exercise.

It’s also possible that you may get enough branched chain amino acids from a healthy diet alone. Taking supplemental BCAAs may or may not be necessary.

Potential Side Effects

When taken as directed, BCAAs do not typically cause serious side effects. However, some people report loss of coordination and fatigue. These effects appear to be most common with high doses of branched chain amino acids.

Until you know how BCAAs will affect you, start with a small dose. Avoid driving and other activities requiring high coordination, until you know how BCAAs affect your body.

Bottom Line

Overall, this is a great product if you’re looking for BCAAs. It offers a 2:1:1 ratio, which typically comes highly recommended for strength training and athletic applications. There are no added ingredients or unnecessary fillers – just the three branched chain amino acids!

This product comes in capsules, while most other BCAAs come in powder form. Capsules are definitely more convenient, although some prefer powders that can be mixed into drinks. That’s all just personal preference – pick what works best for your needs.
