nu u nutrition Vitamin D3 3,000 IU – 365 Softgels 1 Year Supply  (365 Tablets)

Vitamin D3 contributes to many important systems in the body, including general muscle functions, bones and teeth, and the immune system. It plays an important role in the regulation of absorption of calcium and phosphorous - minerals that play a role in maintaining bone health.While Vitamin D3 is an important nutrient, it is difficult to obtain naturally. It appears minimally in most diets and the best recognized way to get the right amount is through sun exposure. Because Ultra Violet B rays are the primary source, those who live in the Northern Hemisphere and lead busy lives may not get enough Vitamin D3.
