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.
