Amino Acid Supplements

Proteins are made from 20 amino acids, some essential and some non-essential. The body cannot make the essential amino acids, these need to be taken in through the diet. The branched chain amino acids (or BCAAs) are the three essential amino acids of leucine, isoleucine and valine. BCAAs provide an energy source during exercise and stimulate muscle rebuild post-exercise.
