    Vitamin E for Peyronie's Disease

    Vitamin E is the most tried supplement for Peyronie's — and controlled trials show it works no better than placebo. Guidelines recommend against it; early traction therapy during the active phase is where the real evidence sits.

    Overview

    Vitamin E is the most tried supplement for Peyronie's — and controlled trials show it works no better than placebo. Guidelines recommend against it; early traction therapy during the active phase is where the real evidence sits.

    Verdict

    Insufficient evidence

    How It Works

    The rationale was antioxidant activity limiting scar (plaque) formation in the tunica albuginea. The mechanism is plausible in theory, but plausibility has not translated into measured benefit.

    Evidence is insufficient. Vitamin E at 200-600 IU/day was one of the earliest oral treatments tried for Peyronie disease, on an antioxidant rationale, and it remains widely used - but controlled trials have not shown it outperforms placebo for plaque size, curvature or pain, and the American Urological Association guideline does not recommend oral vitamin E for Peyronie disease. Pain in the acute phase usually settles spontaneously, which makes uncontrolled reports of improvement unreliable.

    Evidence

    What the studies say

    Controlled studies of vitamin E for Peyronie's — including comparisons against placebo and against other agents — consistently show no significant improvement in curvature, plaque size, or pain. Urology guidelines (AUA) explicitly advise against vitamin E. Penile traction therapy has the strongest non-surgical evidence during the active phase, and intralesional collagenase has RCT support for stable curvature.

    We can affirm that vitamin E can help to prevent the progression of PD. This study strongly supports the recommendation that the best approach for treating PD is multimodal therapy.

    This study did not show significant improvement in pain, curvature or plaque size in patients with PD treated with vitamin E, propionyl-L-carnitine, or vitamin E plus propionyl-L-carnitine compared with those treated with placebo. Note: an Expression of Concern (PMID 36626346) was issued for this paper in 2023.

    Safety

    Caveats

    High-dose vitamin E carries bleeding risk and a signal of increased all-cause mortality in meta-analyses at 400 IU+. Using it delays traction therapy during the window it works best.
