Gamma-Tocopherol

Vitamin E Isoform

Gamma-tocopherol is a tocopherol isoform distinct from alpha-tocopherol and from gamma-tocotrienol. Human handling favors alpha-tocopherol retention, while gamma-tocopherol is cleared more rapidly to CEHC metabolites.

Pharmacokinetic model

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

  1. Studies in humans using deuterium-labeled alpha- and gamma-tocopherols demonstrate faster plasma gamma-tocopherol disappearance and greater gamma-metabolite production Leonard SW, Paterson E, Atkinson JK, Ramakrishnan R, Cross CE, Traber MG · Free Radical Biology and Medicine, 2005 DOI

    Fourteen adults received about 50 mg each of deuterium-labeled alpha- and gamma-tocopheryl acetates. Labeled gamma-tocopherol disappeared more than three times faster, with about 13-hour half-life and greater CEHC…
