Best Vitamin E for Hair

Why Vitamin E for Hair

Vitamin E plays a supporting role in hair. 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 hair benefits. Natural d-alpha form is 2x more bioavailable than synthetic; mixed tocopherols provide broader antioxidant coverage Learn more

•One small RCT (38 volunteers, 8 months) showed tocotrienol supplementation increased hair count by 34.5% vs placebo
•Single study only — needs replication with larger sample size
