Amino acids are the building blocks of protein and are needed in several internal functions of the body. They are classified as "essential" or "non-essential", with essential amino acids meaning they cannot be manufactured by the body and must be supplied in the diet to maintain good all-round health. Amino acids can be further used by the body to create hormones, enzymes, neurotransmitters, antibodies and nutrient carriers. A suboptimal intake of the essential amino acids increases the body's need for the non-essential amino acids either through diet or supplementation. Foods that increase amino acid intake are meat, beans, cheese and eggs.

Tyrosine is a non-essential amino acid and can be found in dairy products, meats, fish, eggs, nuts, beans, oats and wheat. Tyrosine is the precursor of the stress hormones adrenaline and nor-adrenaline, which are responsible for the body's fight or flight' reaction. Chemical messengers that are involved in brain processes also uses Tyrosine.
