Vitamin E
Vitamin E (Alpha-tocopherol)
The common vitamin E form. Distinct from tocotrienol, which is the form with the single small Malaysian RCT. No alpha-tocopherol AGA evidence.
How Vitamin E works — and how well we know it
Fat-soluble antioxidant. The hair-loss claim rests on generic antioxidant logic, not specific mechanism. Notably, the only positive RCT in the vitamin E family used tocotrienol, not alpha-tocopherol.
oral
15 mg/day (RDA). Supplement marketing often uses 400–800 IU.
Standard supplement form. Distinct from tocotrienol — the related compound with the single small Malaysian AGA RCT.
Nothing AGA-specific.

Why the grade is F. No AGA-specific RCT of alpha-tocopherol. The positive vitamin E hair study used tocotrienol — a different compound. Conflating the two is misleading.

1Open-LabelWeight: ModerateAlpha-tocopherol has no AGA RCT — the positive vitamin E study used tocotrienolThe positive vitamin E hair study used tocotrienol, not the alpha-tocopherol that's in most supplements.
Absence of alpha-tocopherol-specific AGA evidence in indexed databases; the only positive vitamin E AGA trial (Beoy 2010) used mixed tocotrienol, not alpha-tocopherol.
No alpha-tocopherol AGA RCT exists.
Marketing that cites 'vitamin E helps hair growth' typically references the Beoy tocotrienol trial — but most supplements contain alpha-tocopherol, not tocotrienol. This is a common ingredient swap that misrepresents the evidence.

What's still missing from the science
- Any alpha-tocopherol-specific AGA RCT.
Our verdict on Vitamin E
Not in our formulary yet
We don't carry this ingredient. We only formulate around actives where the evidence — and the safety profile — is strong enough to recommend with confidence. As the data matures, we may revisit.

A genuine cause of reversible hair shedding in iron-deficient patients — but useless and potentially harmful if your iron stores are normal.
