2. PROTEIN - Protein is a source of building material for muscles. A positive nitrogen balance is the key to gain muscle mass. The RDA for protein for active athletes is 1.8-2.0 g per pound of body weight, which corresponds to approximately 25-30% of calories.
3. L-GLUTAMINE - Inhibits the breakdown of proteins and facilitate their recovery. It facilitates the acquisition of muscle strength and mass. It is the most valuable sports supplements. During the hard work comes to a significant breakdown of protein - catabolism, which on the one hand promotes anabolism (protein building), on the other hand, when it inhibits the development of excessive weight. In the first period of recovery after exercise, most of the anabolic potential of cells is directed to the recovery of losses, and only then is the superstructure of proteins leading to the development of muscles. Glutamine optimizes the process alleviating catabolism. Glutamine is also the primary warehouse and distributor of nitrogen - an element essential for muscle building.
