Myth-buster
A meta-analysis found no link between vitamin D levels or intake and melanoma risk — but the evidence is too thin to call it settled.
This is one of the first comprehensive looks at the question, so the null result challenges the popular idea that vitamin D protects against melanoma, but the limited quality of the underlying studies means we can't rule out a real effect — the picture is now contested, not closed.
Researchers pooled existing studies on vitamin D and melanoma and found that neither blood levels of vitamin D nor how much people got from food or supplements was statistically tied to their risk of developing melanoma. However, the analysis also noted that the evidence it drew from was limited in quality, and the dose of vitamin D wasn't specified in the included studies, so the findings don't rule out a possible effect at very high or very low intakes.
Where this fits in the evidence
This is among the first studies we've indexed on Vitamin D for Reduced Melanoma Risk — treat it as an early signal until more research accumulates.
