Natural Amino Acid Supplements

Amino acids are the building blocks of protein, which are the building blocks of muscles, skin, hair, enzymes and are involved in numerous functions in our body. EarthTurns.com offers pure, all natural amino acids. There are a total of 20 amino acids that make up the various proteins of the body. Of these, 8 are called essential amino acids. They are called essential, because the human body cannot make them, and they are required for the body to perform optimally, heal and grow. Amino acid requirements vary with the health and age of the individual.
