Also known as cholecalciferol, vitamin D3 is a fat-soluble vitamin that supports bone health, immune function, cell growth, and more.* Your body can produce it on its own through the skin cells in response to sun exposure. It can also be obtained through certain food sources and supplements. Sunrider® Vitamin D3 is a way to replicate the vitamin D benefits of sunshine, without exposing your skin to UV rays.

Vitamin D deficiency is a global health problem. An estimated 1 billion people suffer from serious vitamin D deficiency, while up to half of the global population doesn't have adequate levels of vitamin D. Limited exposure to sunshine, sunscreen use, malabsorption, dietary habits, and a busy lifestyle can all contribute to inadequate vitamin D levels.
