Free Form

L-Tyrosine is a non-essential amino acid synthesized in the body from the essential amino acid phenylalanine. L-Tyrosine is the direct precursor to several important neurotransmitters, which affect many functions in the brain, including mood, stress response, mental function, satiety and sex drive. L-Tyrosine is also an important component of hormones that are produced by the thyroid. These hormones are in turn key for managing metabolism. L-Tyrosine is required to form melanin, the dark pigment present in the skin to shield the body from the harmful effects of ultraviolet light.†
