There is some evidence that dietary vitamin D reduces the risk of melanoma1 2.

This meta-analysis probably underestimates the effect of vitamin D for two reasons:

  • dietary vitamin D is a small component of the total vitamin D supply, and
  • the beneficial effect of vitamin D may come much earlier in life than studied in observational studies.
A recent review suggested that vitamin D might reduce the risk of developing melanoma, and that serum 25(OH)D levels of 75-100 nmol/L (30-40 ng/mL) might be adequate3.
