How Vitamin E supports longevity
Vitamin E is a supporting nutrient for longevity support. Natural d-alpha-tocopherol is twice as bioavailable as synthetic dl-alpha-tocopherol, since the body only utilizes four of the eight synthetic stereoisomers—always check labels for the "d-" prefix. Mixed tocopherols (alpha, beta, gamma, delta) provide broader antioxidant protection than alpha alone. Tocotrienols, the other vitamin E family, offer additional cardiovascular and neuroprotective benefits not shared by tocopherols.
Effective dosing
Most evidence supports 50–268 mg of vitamin e daily. Equivalent to 100–400 IU natural d-alpha-tocopherol. Products below this range may not deliver meaningful results.
Form and bioavailability
Avoid dl-alpha tocopheryl — synthetic, ~50% activity. Look for d-alpha tocopherol or mixed tocopherols for better absorption.
Clinical research
Vitamin E has strong clinical evidence for longevity benefits. Natural d-alpha form is 2x more bioavailable than synthetic; mixed tocopherols provide broader antioxidant coverage Learn more
