Vitamin D (calciferol) is a fat-soluble vitamin that is not only found in food (such as milk), but can also be made in your body after exposure to ultraviolet rays from the sun.
The main role of Vitamin D is to maintain normal blood levels of calcium and phosphorus. It aids in the absorption of calcium, helping to form and maintain strong bones, especially during growth periods. It also promotes bone mineralization in conjunction with a number of other vitamins, minerals, and hormones.
A Vitamin D deficiency may have many side effects. Rickets (bowing of the bones) is caused by Vitamin D deficiency in children and infants. The elderly and others who do not get much sun exposure are also at risk for Vitamin D deficiency. Vitamin D deficiency may also result in the softening of the bones and abnormal bone formation.
One in every seven adults has been reported to be Vitamin D deficient. Brief and casual exposure to sunlight can provide enough Vitamin D to meet your needs.
