Metabolics carries a comprehensive range of pure amino acids required for protein synthesis and other important functions within the body.

Amino acids are the building blocks of protein which is needed for the growth and repair of the cells in our body. There are a total of 20 amino acids, 9 of which are essential. These cannot be manufactured by the body and have to be supplied from dietary foods or supplementation. The body can make the other 11 amino acids, but under some circumstances the body uses more of these than it can manufacture, such as during periods of exercise.

The essential amino acids are Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan and Valine.

The non-essential amino acids are Alanine, Arginine, Asparagine, Aspartic acid, Glutamine, Glycine, Proline, Serine, Tyrosine, Cysteine and Glutamic acid.

Cysteine and Glutamic acid can become essential during stress. Browse below for Metabolics' complete range of amino acids.
