6. Branch Chain Amino Acids (BCAA)
BCAAs are made up of the amino acids L-Valine, L-Leucine, and L-Isoleucine respectively. BCAAs are found naturally in foods such as red meat and dairy products. They are necessary for promoting the healing of wounds and, during exercise, they are known for preventing the breakdown of muscle tissue. Essentially they decrease the speed at which proteins break down while at the same time promoting their formation, which helps build muscle.
