Ultramodern BCAA 2X to enhance all-round athletic power + performance

Some supplements use cheap BCAAs in skewed ratios – up to 10:1:1 (L-Leucine, L-Isoleucine, L-Valine). But low-grade BCAAs may be harder to absorb, and some ratios lack research.

Performance Lab® SPORT BCAA supplies the optimal research-backed 2:1:1 ratio in 2X forms: Ajipure®, made with Ferment-A-Pure technology; and our own fermented NutriGenesis® BCAAs.

SPORT BCAA is delivered in vegan-friendly NutriCaps® – a clean, convenient alternative to artificial flavors, sweeteners and synthetics other supplements use to mask BCAAs’ bad taste.

Supplement Facts
Buy NowPerformance Lab® SPORT BCAA

BCAA (Branched-Chain Amino Acids) 2:1:1, 3000 mg

L-Leucine 1500 mg (Ajipure® 1450 mg + NutriGenesis® 50 mg)
L-Isoleucine 750 mg (Ajipure® 725 mg + NutriGenesis® 25 mg)
L-Valine 750 mg (Ajipure® 725 mg + NutriGenesis® 25 mg)


BCAAs (branched-chain amino acids) – comprised of L-Leucine, L-Isoleucine and L-Valine – make up about one-third of the protein found in muscle.

When taken in supplement form, BCAAs are rapidly absorbed into muscle tissues, where they provide a range of athletic performance-enhancing benefits:

  1. Maintaining workout energy by refueling depleted muscle glycogen stores;
  2. Extending muscle endurance by blocking fatigue-inducing brain chemicals;
  3. Stimulating insulin, which enhances uptake of amino acids into muscle tissue cells;
  4. Activating enzymes that stimulate growth hormone and accelerate protein synthesis;
  5. Preserving lean mass while reducing soreness by supplying amino acid muscle-builders.

BCAA Immune Support: BCAAs also maintain blood glutamine levels after exertion, which in turn helps strengthen immune function against gym pathogens and exercise-induced immune challenges.

Some supplements may use incorrect amino ratios and hard-to-absorb forms that limit BCAAs’ muscle-building potential.

SPORT BCAA presents branched-chain amino acids in a muscle-correct 2:1:1 ratio of L-Leucine to L-Isoleucine and L-Valine.

Structurally similar, SPORT BCAA L-Leucine, L-Isoleucine and L-Valine supply versatile support for athletes of all levels, ultimately combining to form about 35% of muscle tissue:

L-Leucine: The most important BCAA for muscle, L-Leucine helps protein synthesis, muscle growth and repair. It also fights catabolism while promoting growth hormone and bone strength.

L-Isoleucine: Required for hemoglobin that enables red blood cells to transport oxygen to hard-working muscles. L-Isoleucine also helps tissue healing, energy and immune function.

L-Valine: Required for protein formation, L-Valine optimizes muscle tissue growth and repair while serving as a key source of muscle energy. L-Valine may have stimulating activity.

Muscle Soreness

Designed for performance, SPORT BCAA supplies L-Leucine, L-Isoleucine and L-Valine as a blend of the world’s two most technologically advanced forms:

  1. Ajipure®: Clean, bioavailable BCAAs made from non-GMO, gluten-free vegetable-derived carbohydrates using patented, eco-friendly Ferment-A-Pure technology.
  2. NutriGenesis®: Lab-grown BCAAs complexed with absorption-enhancing natural cofactors including probiotics, fiber, enzymes and antioxidants.

With Ajinomoto® + NutriGenesis®, Performance Lab® has curated for you the cleanest, most bioavailable muscle-boosting branched-chain amino acids on the market.

Who should take Performance Lab® SPORT BCAA?

Branched-chain amino acids are ideal foundation nutrients for supporting any and all fitness programs, from strength training to endurance athletics. SPORT BCAA functions as both a pre-workout supplement, powering and extending peak muscle performance; and a post-workout supplement, helping to promote optimal muscle growth and recovery. With its broad-spectrum support for muscle health, SPORT BCAA should be taken as a starting point for anyone seeking to achieve the best possible results from their fitness program.

How do I take Performance Lab® SPORT BCAA?

For best results take SPORT BCAA 2-4 capsules 45-60 mins pre-workout and 2-4 capsules immediately post-workout. During especially intense physical training, you may take an additional 2-4 capsules mid-way through your session as an intra-workout supplement.

Is Performance Lab® SPORT BCAA safe?

Like all Performance Lab® supplements, SPORT BCAA is designed to be safe for long-term daily use, without the need for cycling. SPORT BCAA achieves this by using pure, potent branched-chain amino acids that are presented in optimal ratios, dosed appropriately and in line with clinical research. SPORT BCAA’s clean formula design – free of GMOs, gluten, soy, colorants, preservatives and other additives – is also well-tolerated by the body; safe and beneficial for long-term use.

Is Performance Lab® SPORT BCAA legal?

Yes. SPORT BCAA is a safe, natural and 100% legal way to support. SPORT BCAA is also tested for banned substances, and appropriate for amateur, collegiate and professional athletes.

Is 2:1:1 really the optimum BCAA ratio? Some companies sell different ratios such as 4:1:1 and claim they are better.

Any BCAA supplement in any ratio is going to support healthy muscle growth and function. Some manufacturers will load up on L-Leucine – in 4:1:1 ratio or even higher, up to 10:1:1 – because L-Leucine is generally considered the most anabolic of the three. The concern: As BCAA ratios go up, research and safety data goes down. The 2:1:1 ratio found in SPORT BCAA is the most evidence-backed form of BCAA available. In addition, Performance Lab® uses a 2:1:1 ratio for balanced delivery of all BCAAs’ diverse muscle benefits, not just the isolated anabolic activity of L-Leucine.
