N-Acetyl-L-Tyrosine (NALT)
NALT is a water-soluble acetylated tyrosine derivative. Solubility is not proof of superior oral bioavailability: intravenous studies show substantial unchanged urinary loss, and no controlled human evidence validates marketed focus or mood claims.
Pharmacokinetic model
A route-level PK model for n-acetyl-l-tyrosine (nalt) is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.

N-acetyl-L-tyrosine as a tyrosine source in adult parenteral nutrition
In 13 adults receiving continuous parenteral nutrition, about 35% of administered NALT was excreted unchanged in urine. This direct human study concerns intravenous nutritional use and gives no support to claims of…
