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 Branched Chain Amino Acid 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. BCAAs 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. Currently, it is difficult to provide an exact dose of BCAAs per kg body weight that influences muscle growth and prevents breakdown.
