Re: Should vitamin D supplements be recommended to prevent chronic diseases?
We agree with dr. Adamidou and dr. Udo that mental illnesses constitute a very important group of diseases and that there are indications that vitamin D might play a protective role. However, in line with the conclusion regarding other types of chronic diseases reported in our review, there is currently no clear evidence for recommending vitamin D supplementation to prevent these diseases.
This is not to say that vitamin D should be ignored, and prevention and treatment of vitamin D deficiency is of importance in these patients as in the rest of the population.
