What is Vitamin D? It is unique compared to other vitamins because when your body gets it, it turns it into a hormone. This hormone is sometimes called “activated vitamin D” or “calcitriol.”
When you get vitamin D in your skin from sunlight and the vitamin from supplements, is has to be changed by your body a number of times before it can be used. Once it’s ready, your body uses it to manage the amount of calcium in your blood, bones and gut and to help cells all over your body to communicate properly.
Some of the functions of the body that vitamin D helps with include:
- Immune system, which helps you to fight infection
- Muscle function
- Cardiovascular function, for a healthy heart and circulation

- Brain development
- Anti-cancer effects
