What is Vitamin D? What are the Benefits and Harms? Which Foods Have Vitamin D?

Vitamin D; It is a fat-soluble vitamin that aids in calcium absorption and promotes bone growth and mineralization. It is also involved in various functions of the immune, digestive, circulatory and nervous systems.

Studies suggest that vitamin D may help prevent various diseases such as depression, diabetes, cancer and heart disease.
