Which vitamin is provided by sunlight to the body?

Sunlight allows the body to synthesize Vitamin D, particularly Vitamin D3. When UVB rays strike the skin, 7-dehydrocholesterol responds to the sunlight and converts to previtamin D3, which then gets converted in the liver and kidneys to become activated. Vitamin D3 plays a central role in the proper functioning of the immune system and the maintenance of healthy bones. allows the body to synthesize Vitamin D, particularly Vitamin D3.
