Vitamin D3, which is a form of vitamin D, is beneficial because it works in conjunction with calcium to maintain bone health and alsomay prevent a vitamin D deficiency that can lead to osteomalacia andrickets. This vitamin also may be useful forconditions like osteoporosis and hypertension, relates Mayo Clinic.
Similarly, some evidence suggests that low levels of vitamin D may be connected to an increased risk of diabetes type 1, reports WebMD; therefore getting adequate amounts of this vitamin may be beneficial for this condition. There are some recent studies that also suggest that vitamin D may reduce blood pressure and inhibit the growth of certain cancer cells. Vitamin D has many other functions in the body, including aiding in the reduction of inflammation and regulatingthe immune system, says the National Institutes of Health's Office of Dietary Supplements.
Vitamin D3 is the natural form of vitamin D that is manufactured by the skin after sun exposure. D2 is the other type of vitamin D, but this form comes from plants. By exposing the skin to the rays of the sun for at least 10 minutes every day, a person can prevent vitamin D deficiencies, states Mayo Clinic. Very few foods can provide adequate amounts of vitamin D. People who do not get an adequate amount of this vitamin through either sun exposure or diet may require supplementation to avoid deficiencies. The daily recommended allowance forvitamin D for children and adolescent is 600 IU, according to the National Institutes of Health's Office of Dietary Supplements.
