Vitamin E (alpha-tocopherol / mixed tocopherols)
Essentials · Vitamin
Tier B-
Bottom line
Read Off Label grades Vitamin E (alpha-tocopherol / mixed tocopherols) as B- (6.1/10) based on strong evidence, low-med benefit magnitude, and a med-risk safety profile.
Largely abandoned as a longevity supplement after multiple large RCTs (HOPE, SELECT, ATBC) failed to show benefit and several showed harm.
Studied, labeled, or reported-use context: 15 mg/22 IU RDA from food; supplement 100-400 IU mixed tocopherols if used; high-dose synthetic… — OTC; not individualized guidance.
What the evidence says
Largely abandoned as a longevity supplement after multiple large RCTs (HOPE, SELECT, ATBC) failed to show benefit and several showed harm. NASH is the only solid remaining indication (PIVENS trial). Mixed tocopherols safer than isolated alpha-tocopherol because high alpha displaces gamma from tissues. Food sources include almonds, sunflower seeds, and leafy greens; supplementation has not outperformed dietary intake in major outcome trials.
Mechanism
Fat-soluble antioxidant; protects PUFAs in cell membranes from lipid peroxidation; alpha-tocopherol the dominant circulating form, gamma-tocopherol and tocotrienols have distinct mechanisms (gamma traps reactive nitrogen species; tocotrienols inhibit HMG-CoA reductase)
Studied, labeled, or reported dose & route
15 mg/22 IU RDA from food; supplement 100-400 IU mixed tocopherols if used; high-dose synthetic dl-alpha-tocopherol monotherapy has adverse outcome signals
This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
