Provitamin D

Also known as the "sun vitamin", provitamin D is not often found in food and thus, its intake does not cover our body’s needs. However, as the above description demonstrates, a prerequisite for the formation of provitamin D in our body is the exposure to a beautiful sunshine. Vitamin D is a key factor in the development and maintenance of the human skeleton’s natural function. The amount of vitamin D produced internally depends on the strength of the ultraviolet radiation received.
