The non-essential amino acids are those which may be synthesized within the body and are not mandatory within the diet. They include:

  • alanine
  • arginine
  • aspartate
  • glutamate
  • glycine
  • proline
  • serine

As cysteine and tyrosine require the presence of methionine and phenylalanine respectively, they may be considered as non-essential amino acids only if their precursors are available within the diet.
