N-Acetyl L-Tyrosine

N-Acetyl L-Tyrosine (NALT) is a transient receptor potential cation channel subfamily V member 1 (TrpV1) agonist. It is an amino acid derivative of tyrosine, which acts as a direct precursor for melanin synthesis in the body. NALT also has a role in dopamine production and metabolism, as well as other neurotransmitter functions like serotonin and glutamate metabolism.


N-Acetyl L-Tyrosine is a modified version of the amino acid L-Tyrosine. It is used as a supplement in the form of capsules or powder, and it can be found in some foods such as spirulina.

N-Acetyl L-Tyrosine was first synthesized in the 1920s by Eiichi Takamine and his team at Parke Davis & Co., who also discovered adrenaline (also known as epinephrine).


N-Acetyl L-Tyrosine (NALT) is a naturally occurring amino acid that can support mental performance and focus. It may also help to increase energy levels.

  • Improves mental performance. NALT is an amino acid that has been shown to improve mental performance in both healthy individuals and those with attention deficit hyperactivity disorder (ADHD).
  • Improves focus. Research has found that NALT helps people focus by decreasing the amount of distractions they experience when trying to concentrate on a task or activity, such as reading or solving math problems.
  • Increases energy levels . Some studies suggest that supplementing with NALT can help boost your energy levels by increasing the production of dopamine, which is responsible for keeping you mentally alert during the day.


Although the safety of this supplement has not been studied extensively, it appears to be safe for most people when taken at the recommended dosage.

However, there are certain groups who should avoid taking N-Acetyl L-Tyrosine:

  • Pregnant or breastfeeding women should avoid taking N-Acetyl L-Tyrosine as there is insufficient evidence about its effects on pregnancy and lactation.
  • People with bipolar disorder should avoid taking N-Acetyl L-Tyrosine as it may worsen mania symptoms in some cases.
  • Individuals with schizophrenia should avoid using N-Acetyl L-Tyrosine as there is a risk that it could worsen psychotic symptoms such as hallucinations or delusions.


N-Acetyl L-Tyrosine is a great supplement for anyone interested in improving their cognitive function. It has been shown to improve memory retention and recall, increase alertness and focus, reduce anxiety and depression symptoms, and boost motivation levels during stressful situations (such as exams).
