The American Academy of Dermatology (AAD) has issued a position statement on vitamin D, saying that it is “essential for optimal health.”
The AAD recommends that people obtain vitamin D through eating a healthy diet of vitamin D rich foods, fortified foods, and dietary supplements. They also suggest that people follow the National Academy of Science Institute of Medicine guidelines concerning adequate intake levels (14-50 years 200 IU, 51-70 years 400 IU, 71+ years 600 IU).
However, they advise against boosting vitamin D levels by unprotected sunbathing or using sunbeds: “Unprotected UV exposure to the sun or indoor tanning devices is a known risk factor for cancer. Studies have shown that UV radiation from both the sun and tanning devices can cause oncogenic mutations in skin cells” They also warn that the use of sunbeds has been linked to an increased risk of melanoma and squamous cell carcinoma. The academy recommends that people should use a “comprehensive photoprotective regimen, including the regular use and proper use of a broad-spectrum sunscreen” to minimize the risk of UV-induced skin cancers.
