The main role of vitamin D is to help regulate blood levels of calcium, phosphorus, and (to a lesser extent) magnesium. Vitamin D is vital for the growth and health of bone; without it, bones will be soft, malformed, and unable to repair themselves normally, resulting in diseases called rickets in children and osteomalacia in adults. Vitamin D comes from two sources: endogenous(D3), which is produced in the skin on exposure to sunlight, and exogenous(D4), which is ingested in foods and supplements.
