Amino acids are classified as either essential or non-essential. Essential amino acids cannot be synthesised in the body and must be obtained from the diet, whereas non-essential amino acids, whilst still essential for health, can be synthesised in the body and are therefore not classified as essential.

Tyrosine is considered a non-essential amino acid because the body can make it from phenylalanine. It is important to brain nutrition because it is a precursor of the neurotransmitters - dopamine, adrenaline and noradrenaline. It also acts as a precursor for certain hormones, including thyroxine and for the major human pigment melanin.
