Branched chain amino acids (BCAAs) are a group of essential amino acids, meaning your body doesn't make them, so they must be supplied by the diet. Strenuous resistance exercise can cause muscle damage and soreness and BCAAs have been shown to help promote lean mass and a support healthy weight.See All Products
Below we've broken down the main functions of our BCAAs and the benefits it can provide.
Research has shown that supplementation with branched chain amino acids, when combined with a resistance training program resulted in a greater decrease in percent body fat as well as an increase in lean mass.
Branched chain amino acid supplementation can reduce tryptophan uptake and delay fatigue. Participants also recorded ratings of perceived exertion and mental fatigue reduction with supplementation.
BCAAs, especially leucine, are shown to create anabolic effects on protein metabolism by improving the rate of protein synthesis and decreasing the rate of protein breakdown in human muscle.
BCAAs have been shown to promote an increase in lean mass and reduction in body fat percentage when consumed in conjunction with a resistance training program.
