ABSTRACT

Vitamin D regulates the serum calcium and phosphorus levels by effecting absorption and metabolism of these minerals. Since determining the vitamin D reseptors are expressed in many tissue and cells, non-clasical effects of vitamin D was begun to be investigated. Promising results with non-hypercalcemic doses of vitamin D are available in many diseases such as diabetes mellitus, multiple sclerosis, amyotrophic lateral sclerosis and metabolic syndrome. Additionally the patient selection, risk factors and doses of the vitamin are uncertain. We aimed to review non-routine usages of vitamin D and obtained results.
