After fitness workouts, metabolism remains elevated and the build-up of muscle protein is stimulated. Amino acids are the building blocks of these proteins. Branched Chain Amino Acids (BCAAs) belong to the 9 essential amino acids, which cannot be synthesized by the human body itself ? thus the intake needs to be covered through nutrition. The BCAAs L-Leucine, L-Isoleucine and L-Valine make up approximately 20-35% of human muscle protein. Conveniently sized and easy to swallow Dymatize BCAA 2200 capsules are perfectly suited for on-the-go in the morning, before or after training ? delivering the three essential branched chain amino acids in a 2:1:1 ratio as well as vitamin B2 (riboflavin) and vitamin B6. Vitamin B2 and vitamin B6 contribute to the reduction of tiredness and fatigue.
