Ostrovit's BCAA 8:1:1 powder is a dietary supplement with branched-chain amino acids in an 8:1:1 ratio. These amino acids include leucine, isoleucine, and valine, which are essential and must be supplied to the body through diet. It is ideal for physically active people who perform intense and heavy training.

Leucine is one of the most important compounds for building muscle mass and has anabolic processes. Moreover, it increases muscle sensitivity to the anabolic effect of insulin and the amount of ATP in muscle cells.
