Amino acids are the building blocks of protein, meaning that when protein is digested by the body it is broken down into individual amino acids, which are then selectively grouped together to help with various bodily functions. The body is unable to produce essential amino acids - they must be consumed as part of your diet - whereas non-essential amino acids can be found in varying quantities within the body. You can read more about them in our Mass Guide to Amino Acid Supplements.
