Study: Vitamin D reduces risk of melanoma and other skin cancers

New study showed that regular vitamin D supplementation was associated with a significant reduction in the risk of melanoma.

The researchers also found that people who regularly took vitamin D supplements had a lower risk of developing other types of skin cancer.

The new study was conducted by the Northern Savo Skin Cancer Program in Finland and included 498 adult patients at increased risk of developing skin cancer:

Basal cell carcinoma

Squamous cell carcinoma


Serum calcidiol (vitamin D in the blood) levels were analyzed in half of the patients and found to be consistent with their self-reported intake of vitamin D supplements.

The key finding was that there were fewer participants with melanoma among regular vitamin D users—only 18 percent compared to 32 percent among those who did not take vitamin D supplements.

When the researchers looked at other skin cancers, only 62% of regular supplement users had a history of skin cancer, compared to almost 75% of those who didn't.
