Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. You need them for vital processes such as protein synthesis, hormones, and neurotransmitters. Some people also take certain branched-chain amino acids in supplement form as a natural way to boost muscle growth, athletic performance, or improve mood.
Amino acids are categorized as essential amino acids, conditionally essential amino acids, or nonessential amino acids, depending on several factors. Other amino acids also play important roles in amino acid metabolism and overall health.
