Vitamin D is a class of prohormones that is used by animals to make steroidal hormones. Plants do not need these compounds.
Vitamin D is needed for calcium to be made useful in the body (for instance in bones). As you get older you tend to lose calcium from the bones and it becomes necessary to try and prevent this by ensuring that there is enough calcium in the diet and that this calcium is usable by the body. Vitamin D is made in the body by the action of UV sunlight on the fat layers just under the skin. If there is not enough exposure to sunlight the body becomes short of vitamin D and bode deformities can occur in growing children (rickets). Therefore in the young and the old it is important that both Calcium and vitamin D are present in the diet.
All the Vitamin D you need can be received through 15 minutes of sunlight a day.
