BCAA Muscle Recovery Formula

The BCAAs, l-leucine, l-isoleucine, and l-valine, are probably the most essential amino acids for athletes in training. They account for 33% of muscle protein. Some experts believe that even moderate exercise can increase your body''s need for leucine by up to 240%.

During long-term and sustained exercise, muscles use large amounts of amino acids as a source for energy. The body prefers to use BCAAs for energy, since they readily replace glucose in the energy production pathways. As muscles begin to use BCAAs, the amounts of these amino acids drop, which allows tryptophan to enter the brain, inducing fatigue and tiredness. Research shows that supplementation with branched-chain amino acids can prevent central fatigue by tightly regulating the amount of tryptophan. Supplementation before and during exercise has been shown to help enhance performance.
