Molecular Formula:


Molecular Weight:





1.N-Acetyl-L-Tyrosine is a highly bioavailable form of L-tyrosine for the natural precursor treatment of low moods N-acetyl-L-tyrosine can be used in lower doses than L-tyrosine.


2.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.


3. 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.


4. N-acetyl-L-tyrosine 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.
