N-Acetyl Tyrosine 350 is an acetylated derivative of the essential amino acid L-tyrosine. Ordinary tyrosine is less stable and is insoluble 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 improving the synthesis of the catecholamines norepinephrine and dopamine (neurotransmitters).
