Vitamin D plays an important role in several bodily functions. This vitamin is fat soluble and has been at the center of attention in recent years.
Vitamin D helps absorb calcium in the small intestines and is essential for bone growth and maintaining bone density. This vitamin is believed to have some role in the prevention of cancer, autoimmune conditions, heart disease, infections, and a number of other conditions.
Natural sources of vitamin D
1) Vitamin D2 (ergocalciferol): Is synthesized in plants and fungi following the exposure to ultraviolet light.
2) Vitamin D3 (cholecalciferol): Ultraviolet-B radiation from the sun prompts the production of vitamin D3 from 7-dehydrocholesterol (7-DHC) in the skin.
