NOW Foods L-Tyrosine 500 mg is a dietary supplement providing 500 mg of free-form L-Tyrosine per capsule. L-Tyrosine is an amino acid that serves as a precursor for several neurotransmitters, including dopamine, norepinephrine and epinephrine.

L-Tyrosine also plays a role in the normal function of the thyroid gland and contributes to the production of melanin.
Each capsule contains 500 mg of pharmaceutical-grade L-Tyrosine. The formula uses a simple ingredient profile with hypromellose (cellulose capsule), vegetable-source stearic acid and silicon dioxide.
