People can become deficient in Vitamin D because they don’t eat enough Vitamin D containing foods or because they don’t get enough sunlight on their skin. We are more likely to become Vitamin D deficient in the winter. It is harder to absorb Vitamin D if skin is dark or if the skin is covered.

Vitamin D is a fat soluble vitamin that is needed to form and maintain strong bones. Low levels of Vitamin D can result in bones becoming thin and malformed. Low vitamin D can also result in fractures. Vitamin D is also important in maintaining a healthy immune system.
