| A "non-essential" amino acid which acts as a mood elevator and appetite suppressant, and produces melanin in the body so it enhances natural hair color; also used as an anti-depressant and anxiety reliever. Function; Reasons For Use Tyrosine is an aromatic amino acid, the hydroxylated form of the essential amino acid phenylalanine. Tyrosine is a precursor to dopamine, noradrenaline, and adrenalin (epinephrine). Tyrosine has been used as a natural antidepressant (monoamine levels at the synapse can affect mood), memory enhancer, and overall stimulant. Side-Effects While some of the mechanisms are logical, and there is little harm in tyrosine; it is unsure how effective tyrosine supplements can be alone. Care should be taken if long-term use of single amino acid supplements is added to any regimen. |
