One of the Non-Essential Amino Acids
What is Tyrosine?
Tyrosine is a nonessential amino acid that is synthesized in the body from phenylalanine. As a precursor or building block for several important neurochemicals, tyrosine builds dopamine, epinephrine, and norepinephrine, all of which work to regulate mood. These neurotransmitters are commonly depleted in those who have used stimulant drugs for an extended period of time. (See "Neurotransmitters" for more information on the individual neurotransmitters and how neurochemical deficiencies affect the individual.)
Benefits of Tyrosine
Because tyrosine is also involved in the synthesis of enkephalins (opioids), substances that have pain-relieving effects in the body, it appears to have some added pain relief benefits. Tyrosine seems to be especially beneficial when used in conjunction with 5-HTP.
Tyrosine is considered a mild antioxidant as well as having putative antidepressant effects.
Precaution
Tyrosine aids in the production of melanin (pigment responsible for hair and skin color). Those with pre-existing pigmented melanoma should avoid tyrosine supplements, as it is suggested that tyrosine may increase the ability of the melanoma cells to spread.
Before taking any nutritional supplement, including amino acids, please first consult your health care provider.
