Bodybuilders, athletes, weekend warriors who weight train regularly, and endurance athletes who regularly compete in aerobic events such as running, cycling, or swimming will benefit from BCAA supplementation.

Supplementation of BCAAs will help meet the increased demand the body requires under times of stress. Numerous studies have shown that BCAAs can enhance energy levels, build muscle, and speed recovery under a variety of metabolic conditions. Aside from playing an important role in protein synthesis, the BCAAs provide extra energy during heavy lifting, help spare muscle tissue, and fight mental brain drain as you battle through a workout.

BCAA's can be taken at anytime during the day, preferably on an empty stomach to avoid competition for absorption with other amino acids; however, the most beneficial times to take the BCAAs are directly before or just after training.

BCAA's include leucine, isoleucine and valine. They are needed for the maintenance of muscle during physical stress and exercise. Research shows that supplementation with branched-chain amino acids can prevent central fatigue by tightly regulating the influx of tryptophan to the brain. Supplementation before and during exercise has been proven to enhance performance.

BCAAs function as anabolic agents and induce sparing, which allows the body to burn fat and not muscle. 100% Crystalline BCAA 12,000 Powder is designed to increase endurance, lengthen the time to fatigue and improve performance.
