Alpha-Ketoglutarate (AKG)

Endogenous Metabolite

Alpha-ketoglutarate is an endogenous tricarboxylic-acid-cycle intermediate. Free AKG, calcium AKG, ornithine AKG, and mixed keto-acid products are distinct interventions. Longevity claims rely heavily on preclinical or uncontrolled evidence.

Pharmacokinetic model

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