L-Serine

Amino Acid Supplement

L-serine is a proteinogenic amino acid and metabolic precursor. It must be distinguished from D-serine and from racemic serine; high-dose research in rare metabolic neuropathy does not imply benefit or safety for routine use.

Pharmacokinetic model

A route-level PK model for l-serine is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.
