We use superior science to make smarter formulas like Jarrow Formulas® N-Acetyl Tyrosine. It is an acetylated derivative of the amino acid L-tyrosine. Ordinary L-tyrosine is less stable and also less soluble in water, which may result in reduced bioavailability. Acetylation enhances the solubility and stability of certain amino acids. N-Acetyl Tyrosine supports brain function by supporting the synthesis of the catecholamines norepinephrine and dopamine (neurotransmitters). This formula also contains vitamin B6, which is essential for amino acid metabolism. *These statements have not been evaluated by the Food and Drug Administration.
