Applied Nutrition Vitamin D3 - Vitamin D3, Package 90 tabs

Vitamin D functions as a hormone, and every cell in the body has a receptor for it. The human body makes it from cholesterol when your skin is exposed to sunlight, but sunscreen, protective clothing, limited exposure to sunlight, dark skin, and age can prevent you from getting enough vitamin D from the sun. It is also found in some foods, such as oily fish and fortified dairy products, although it is very difficult to get enough from diet alone. The recommended daily allowance (RDA) is usually around 400-800 IU, but many experts say you should get even more than that. Vitamin D deficiency is very common, especially in northern countries.

Vitamin D contributes to the maintenance of normal muscle function and the normal function of the immune system.

Method of administration: Take 1 tablet daily with food.
