Experts Report Little Certainty in Vitamin D’s Potential Benefits « news@JAMA

Conclusions in the statement include the following:

• Topical or oral vitamin D may help treat psoriasis, but more evidence is needed to determine its efficacy in treating other skin disorders or preventing skin cancer.
• No strong evidence exists to support the theory that vitamin D supplements reduce the risk of type 2 diabetes or the metabolic syndrome.
• Clinical trial evidence does not support taking vitamin D supplements to lower cardiovascular disease risk.
• Observational studies linking vitamin D with reduced cancer incidence are strongest for colorectal cancer but weak or inconsistent for breast, prostate, and all cancers combined.

The statement will be published in the June issue of the Endocrine Society’s Endocrine Reviews.
