Which vitamin is provided by sunlight to the human body?
Which vitamin is provided by sunlight to the human body?
Vitamin D is nicknamed the "sunshine vitamin" because our bodies can produce it by themselves when the skin is exposed to sunlight. The trick is that the UVB rays from the sun start a photochemical reaction in the skin. This reaction converts a compound in the skin called 7-dehydrocholesterol into vitamin D3.
