Source Natural's - L-Tyrosine 500 mg 50 Tablets
L-Tyrosine is a free-form amino acid which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine, and epinephrine, as well as for thyroid hormones and enkephalins, special peptides which subdue messages of physical discomfort. Tyrosine is also a precursor for the protective skin pigment melanin.
