Vitamin D3 is important to the body in many other ways as well. A person can also boost their vitamin D3 intake through certain foods or supplements.

Vitamin D3 is essential for several reasons, including maintaining healthy bones and teeth. Despite its name, vitamin D3 is not a vitamin, but a prohormone, or precursor of a hormone.

Vitamins are nutrients that the body cannot create, and so a person must consume them in the diet. However, the body can produce vitamin D3.
