HIT EAA is a supplement to ensure you get a premium quality, bioavailable source of the 9 Essential Amino Acids (EAA's) everybody needs.
One of the biggest challenges when exercising and lifting weights is getting adequate protein via the diet. In order to get maximum benefit from your protein you would need a 'complete' source of protein, meaning it would need to contain all the EAA's. The 9 EAA's include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
