The Branched-Chain Amino Acids (BCAA's) are an important group of essential amino acids consisting of Leucine, Isoleucine and Valine. The BCAA's are among the nine essential amino acids for humans, because our body can’t manufacture them. Their only source is our daily food or food supplementation. On the other hand, they account for 35% of the essential amino acids in muscle proteins. Vitamins B5, B6 and B12 are also included in our formula. These vitamins contribute to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. Vitamin B5 (Pantothenic Acid) is connected to normal synthesis and metabolism of steroid hormones, Vitamin D and some neurotransmitters. Vitamin B6 plays a role in normal protein and glycogen metabolism and together with vitamin B12, in the normal function of the immune system.
