BCAA 3:1:1 is a Branched Chain Amino Acid consisting of L-Isoleucine, L-valine and added L-Leucine. Branched Chain Amino Acids (BCAA) are essential to the human body and critical for muscle hypertrophy (growth) and maintenance. They have a significant positive effect on the generation of various tissues, healing and metabolic processes via protein synthesis in the liver. Unlike most amino acids, BCAAs are predominantly metabolised in the muscles and not in the liver. This demonstrates their extraordinary importance in the energy supply of muscle tissue.
L-Leucine in particular plays a vital role in the generation and preservation of muscle tissue by supporting protein synthesis in the muscle and liver and blocking the breakdown of muscle tissue. It also regulates the energy supply of the body and plays a part in the synthesis of glucose. It is therefore advised to supplement it during low carbohydrate diets.
