There are two types of Vitamin D. Vitamin D2 (ergocalciferol) is obtained from food. It is metabolized by liver to its active form 25 hydroxycalciferol [25 OHD2]. Vitamin D 3(cholecalciferol) is synthesized in skin by sunlight’s UV rays. It is metabolized by liver to 25 dihydroxycalciferol [25 OH D3] is involved in many biochemical functions including calcium and bone metabolism regulation. Vitamin D deficiency is associated with Ricketts, osteomalacia, depression and impaired cognitive function. Elevated vitamin D levels decrease depression. High-dose vitamin D3 is also used to prolong remission intervals in multiple sclerosis (MS) patients.
