BCAA’s stands for Branched Chain Amino Acids which include the most essential amino acids named as valine, leucine & isoluceine & these three amino acids make up almost 1/3 of the skeletal muscle tissues in the human body as well as play a vital role in the synthesis of protein in the body. These essential amino acids are the building blocks of protein & when a person eats food containing protein it is digested & broken into small individual particles. These particles can be absorbed easily into the blood stream & these small particles are called amino acids & short chain amino acids. The absorbed amino acids in the blood stream have far reaching effects on the entire body, they are involved in the process of muscle repair, & important brain functions, hair growth etc & they are also involved in the metabolic pathway. This can be defined as the chain of chemical reactions within the cells to increase the production of protein in the body, this is crucial to build bulky, strong muscles.
