Why Vitamin E for Longevity
Vitamin E plays a supporting role in longevity. 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.
What dose to look for
Clinical studies typically use 50–268 mg of vitamin e. Equivalent to 100–400 IU natural d-alpha-tocopherol. Products below this range may not deliver meaningful results.
What form to look for
Avoid dl-alpha tocopheryl — synthetic, ~50% activity. Look for d-alpha tocopherol or mixed tocopherols for better absorption.
What the research says
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
