    Vitamin E for Peyronie’s disease: check both the guideline and the citation status

    The 2015 AUA guideline advises against oral vitamin E for Peyronie’s disease. A later publication notice also affects one often-cited trial.

    Evidence and findings

    The AUA panel found no convincing efficacy evidence for the listed oral therapies, including vitamin E. It identified costs, distress and delay of useful care as burdens even when an ineffective therapy appears tolerable. [1][2]

    PubMed links a 2023 expression of concern to the 2007 vitamin E and propionyl-L-carnitine trial. That notice must accompany interpretation of the trial; its results are not treated here as dependable standalone evidence. [1][2]

    Interpretation and limits

    An expression of concern is a publication-status warning, not proof that the opposite treatment claim is true. The older guideline is reported with its date, not presented as a new trial. Neither source provides a basis for a home vitamin E dosing protocol. [1][2]

    A hypothetical distinction

    Imagine an older review cites a trial whose status later changes. Reading only the review can miss a material qualification to its evidence base.
