Abstract:
In addition to being important in calcium and phosphorus metabolism, bone formation, and mineralization, vitamin D also plays a part in the maintenance of immune homeostasis. Vitamin D receptors are expressed in a number of different tissues, including, and perhaps most notably, on immune cells. The presence or absence of activated vitamin D has a number of effects on in vitro immune cell function. This review describes the possible immunoregulatory role of vitamin D in rheumatoid arthritis with clinical and animal studies.

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
