About this supplement
N-Acetyl L-Tyrosine (NALT) is an acetylated derivative of the amino acid L-tyrosine. It is commonly used as a dietary supplement due to its improved solubility and bioavailability compared to L-tyrosine alone. NALT serves as a precursor to important neurotransmitters like dopamine, norepinephrine, and epinephrine, and is involved in the synthesis of thyroid hormones and melanin. The acetylation enhances its ability to cross the blood-brain barrier and improves stability. It is marketed for cognitive support, stress resilience, mood enhancement, and physical performance.

Chemical ID (CAS)
537-55-3
Formula
C11H13NO4
Physical properties
White to off-white crystalline powder. Soluble in water. More soluble and stable in solution than L-tyrosine. Typically odorless with a slightly acidic taste.
How it’s made
Produced synthetically via acetylation of L-tyrosine using acetic anhydride or acetyl chloride under controlled conditions. The process involves protecting the amino group of L-tyrosine, followed by reaction with an acetylating agent, and subsequent purification through crystallization.
