BCAA Xtra is a concentrated source of branched-chain amino acids. Branched-chain amino acids build ca. 1/3 of skeletal muscle mass, they have anticatabolic effect, and play an important role in muscle protein synthesis.BCAA XTRA is an ideal solution for people who want to increase muscle mass and strength without adipose tissue increase. One portion (10 g) of BCAA XTRA contains as many as 5 g of branched-chain amino acids in a ratio 2:1:1. The effect of the nutrient is additionally intensified by L-glutamine – amino acid important to protein biosynthesis, and also intensifying muscle strength and resistance. Recommendations: for people who want to intensify muscle strength and mass, and at the same time to reduce adipose tissue. For people practising all sports disciplines, both as recreation and professionally.
