DOES IT WORK?
Good pick. Valine is one of the three Branched Chain Amino Acids (BCAAs) and is considered an essential amino acid. While important for muscle protein synthesis and energy, supplementation is typically only beneficial if dietary intake is insufficient. Effective if you're deficient; otherwise, effects may be limited.
