N-Acetyl-L-tyrosine Picture 
N-Acetyl-L-tyrosine Function:
N-acetyl-L-tyrosine can be used in lower doses than L-tyrosine.
N-Acetyl L-Tyrosine is an acetylated derivative of the essential amino acid L-tyrosine. Ordinary L-tyrosine is less stable and
insoluble in water, which may result in reduced bioavailability.
N-acetyl-L-tyrosine, which is converted in the body to L-tyrosine, is 20 times as soluble in water as L-tyrosine itself. For this
reason, it serves as an efficient supplement for raising tyrosine levels in the body, since undissolved substances are not
absorbed from the digestive tract.
Acetylation enhances the solubility and stability making it a more rapidly absorbed and bioavailable form of the amino acid L-tyrosine which is less prone to urinary excretion.
