People take Vitamin D to support healthy bones and teeth and the immune system.

Vitamin D is known as "the sunshine vitamin." It is produced by the body through the liver and kidneys when the skin is exposed to the sun, specifically UVB rays. Other sources are diet and supplements.

Vitamin D is essential for the absorption of calcium to help maintain strong, healthy bones and bone density. A vitamin D deficiency can lead to rickets in children and osteoporosis in adults. Vitamin D plays a role in immune, nerve, and muscle health. Vitamin D also promotes healthy mood and mental function.

While exposure to the sun is a great source of Vitamin D, factors like age, sunscreen use, geographic location, and skin pigmentation can lead to decreased absorption. People with intestinal problems that limit fat absorption, people with obesity or gastric bypass, people with lactose intolerance or milk allergies, breastfed infants, vegans or vegetarians are also factors in Vitamin D deficiency.

Food sources do not have a sufficient amount of Vitamin D. For these reasons, taking a supplement like Vitamin World's Vitamin D3 is a great way to make sure you're getting enough D everyday!
