N-Acetyl L-Tyrosine Benefits and Uses


L-tyrosine is a non-essential amino acid made naturally by our bodies. Amino acids are the building blocks of protein and play a vital role in maintaining our overall health. N-acetyl L-tyrosine is an acetylated form of L-tyrosine.


N-Acetyl L-Tyrosine is taken commonly as a dietary supplement for its perceived effect in enhancing mood, alertness and improving memory. It is taken anecdotally for its role in improving overall brain function. Clinically, it is also used as a dietary supplement in the management and treatment for individuals that are unable to make tyrosine, a condition known as phenylketonuria.




N-Acetyl L-Tyrosine is known by a number of alternative names including:




(2S)-2-(acetylamino)-3-(4-hydroxyphenyl)propanoic acid






N-Acetyltyrosine (VAN)



Scientific Consensus:


N-Acetyl L-tyrosine is considered to be generally safe when taken as a dietary supplement by adults. Tyrosine seems to be safe when used in doses up to 150 mg/kg per day for up to 3 months. However, side effects that may occur include nausea, headache and heartburn. N-acetyl L-tyrosine is possibly effective at improving memory, alertness and overall mental performance.  


Warning: N-Acetyl L-tyrosine can interact with a variety of medications. It should not be taken with thyroid medication, levodopa, or antidepressant medications known as monoamine oxidase inhibitors (MAOIs).
