Our Liquid Multivitamins contain an amino acid complex comprised of L-Leucine, L-Isoleucine, and L-Valine (2:1:1) which are a few of the essential amino acids (or amino acids that must be acquired through the diet). These specific amino acids are referred to as Branched-Chain Amino Acids (BCAAs) due to their molecular shape. BCAAs are unique from other amino acids as they can be readily utilized by our mitochondria for energy during exercise. BCAAs may also help promote normal muscle function and recovery during exercise. As amino acids, BCAAs are utilized in protein synthesis and help to support the immune system by playing a role in the normal maintenance and development of immune cells.
