N-Acetyl L-Tyrosine, or NALT for short, is considered to be a modified formulation of a non-essential amino acid.
L-Tyrosine is an amino acid that the body is capable of producing internally, but supplementation is often necessary to optimize cognitive function.
NALT is modified from normal Tyrosine because it contains the addition of acetic acid. This actually helps to increase the compound's bioavailability so that it is better absorbed directly into the bloodstream

1. n-acetyl l-tyrosineis 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.
