Vitamin D is often called the “sunshine vitamin,” but its role goes far beyond what most people think. While it’s linked strongly to bone health, it also supports the immune system, helps muscles move, keeps mood steady, and contributes to overall well‑being.

Currently, there is a certain amount of restriction related to the life style that limits exposure from sun-light. Even people who live in the colder climates, sit indoors and apply sunscreen whenever out are unable to produce sufficient vitamin D. Unhealthy habits and some health conditions can also lead to deficiency.
