Vitamin D is an essential vitamin that helps build and maintain healthy bones and teeth.
Without this, our bodies cannot absorb calcium, which is the main component of bone.
Vitamin D may also protect against cancer and diabetes.
Our bodies synthesize vitamin D when sunlight reaches the skin.
The amount of vitamin D that our skin produces depends on several factors, including where we live, season, and skin pigmentation. During winter, vitamin D production may decrease or be completely absent.
