WHAT IS APPROVED SCIENCE® BCAA?

A POWERFUL BRANCHED-CHAIN AMINO ACID SUPPLEMENT

APPROVED SCIENCE® BCAA

is an expertly crafted workout supplement that comes in both powder and tablet form which has been studied and produced in a top-quality, cGMP certified and FDA licensed laboratory environment under the most rigorously professional conditions.

The positive benefits of the ingredients found in Approved Science ® BCAA have been published by organizations such as the Journal of Nutrition, the European Journal of Applied Physiology, and the Journal of Sports Medicine and Physical Fitness.

Approved Science® BCAA - research drives results!

WHY CHOOSE APPROVED SCIENCE® BCAA

FOR ENHANCED WORKOUT PERFORMANCE?

Most other BCAA supplements do not provide a sufficient dosage of BCAAs in a clinically-proven ratio of 2:1:1 (L-Leucine, L-Isoleucine, L-Valine) for optimal muscle building benefits and increased endurance. Most other BCAA supplements do not contain BioPerine ® for increased absorption nor do they provide BCAA powders which are free of dye and sugar. Many other BCAA supplements do not contain vegan-friendly ingredients. The truth is that most BCAA supplements do not live up to their claims. Most do not have the potency needed. And most contain ingredients such as unnecessary proprietary blends, additives, preservatives, fillers or binders which simply water down the results you are likely to experience.

Due to extensive research and our firm understanding of what makes an effective BCAA supplement, we have created two products (pills and powder) that are uniquely formulated to provide the ultimate boost to enhance your workouts and muscle building potential.

Each ingredient was carefully selected, based on years of research and clinical studies. Over 20 years of safety and efficacy research has been documented on what ingredients should be included in a quality BCAA supplement to get the very best results possible with absolutely no side effects.

APPROVED SCIENCE® BCAA #1 CHOICE FOR QUALITY & EFFECTIVENESS

THE BENEFITS

OF APPROVED SCIENCE® BCAA

  • Approved Science® BCAA Pills provide a clinically-proven 2:1:1 ratio (L-Leucine, L-Isoleucine, L-Valine) plus BioPerine® for increased absorption.

  • Approved Science® BCAA Powder also provides a clinically-proven 2:1:1 ratio (L-Leucine, L-Isoleucine, L-Valine) plus added electrolytes and ingredients to boost recovery.

  • Branched-Chain Amino Acids (BCAA) are easily available to the muscles thanks to their unique structure, providing the muscles with immediate energy.

  • Increases the rate of protein synthesis which promotes muscle growth and reduces recovery time and muscle soreness after workouts.

  • Reduces fatigue and improves endurance to prevent burnout during a workout, providing muscles with strength and stamina.

  • Supports the construction of protein in muscle which assists in the repair and growth of muscles.

  • Lowers blood glucose levels by stimulating the uptake of glucose in the muscle tissue providing an immediate energy source.

  • Plays an important role in the processing of protein which keeps you feeling fuller for longer and reduces food cravings.

  • Supports athletic performance by providing more energy during a workout and increases muscle repair for stronger and bigger muscles.

HOW DOES

APPROVED SCIENCE® BCAA WORK?

Approved Science® BCAA Pills and Powder provide a clinically-proven 2:1:1 ratio of L-Leucine, L-Isoleucine, L-Valine; the 3 Branched-Chain Amino Acids which provide numerous benefits for muscle growth and strength. These essential amino acids are not created by the body, so they need to be ingested from an external source. Their unique structure allows them to skip the digestive process and be utilized directly by the muscles for energy. The BCAA tablets also contain BioPerine® to ensure the most efficient absorption of these amino acids into your bloodstream, while the BCAA powder also includes Coconut Water Powder (electrolytes) as well as Glutamine HCL and Citrulline to promote recovery. The ingredients contained in Approved Science® BCAA were selected by a team of doctors and scientific researchers based on clinical data and designed to get results more effectively than any other BCAA supplement available.

Containing the most effective concentration and ratio of BCAAs, this unique supplement provides the ultimate formula to experience incredible results. Many studies document the positive health benefits of BCAA supplements to help improve the duration and intensity of workouts as well as promote muscle growth and strength.

These two top quality BCAA supplements provide many incredible benefits: Boost, Repair, Support, and Maintain - supporting the muscles and synthesis of protein in a way that ensures optimal workout and muscle building benefits.

In terms of quality and purity of ingredients, there is nothing else on the market that comes close to Approved Science® BCAA.

  • STEP #1 BOOST

    Branched-Chain Amino Acids are uniquely structured making them easily utilized directly by the muscles and providing them with energy. This will boost performance and prevent burnout during a workout. BCAAs also boost protein synthesis which builds stronger muscles.

  • STEP #2 REPAIR

    Working out creates small tears in the muscles, which is how they grow bigger and stronger as they repair. Increasing protein synthesis will speed up the rate at which muscles repair themselves, decreasing muscle soreness and promoting muscle growth.

  • STEP #3 SUPPORT

    L-Leucine plays an important role in how the body processes protein. By conserving protein stores, food cravings will be reduced and satiety will be increased which supports weight loss. These essential amino acids support the construction of protein in muscle.

  • STEP #4 MAINTAIN

    BCAAs provide an important fuel source for the muscles which helps maintain energy during a workout and reduces fatigue. Blood glucose levels are regulated by promoting the uptake of glucose in the muscles which provides energy and prevents the breakdown of muscle tissue.
