Amino acids are the main constituents of protein. There are twelve amino acids that can be made by the body, however there are another eight amino acids that are essential, meaning that they must be supplied by the diet or through supplementation.
Amino acids are the building blocks and main constituents of protein. Protein is what provides the body with roughly 10-15 per cent of its dietary energy; it is also needed for both growth and repair. Protein is also a major functional and structural component of all our cells.
There are twelve amino acids that can be made by the body, known as nonessential amino acids. However there are eight other amino acids that must be supplied by the diet; these are called essential amino acids.
Essential amino acids include phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, leucine, lysine and histidine. Amino acid supplements are particularly popular for use by athletes and bodybuilders.
