The Sunshine Vitamin

Vitamin D is an essential vitamin that can be found in cells throughout the entire body. It is necessary for calcium and phosphorus absorption to build and maintain strong bones and teeth, provide immune system support, and for healthy muscle function.

Often referred to as the “sunshine vitamin,” vitamin D3 is synthesized when bare skin is exposed to ultraviolet B (UVB) light. However, studies show that most people do not get the recommended amount from sunlight alone. In fact, according to Mayo Clinic, 25% to 50% or more of the general population may be vitamin D deficient.

NatureWise Vitamin D3 delivers the same biologically active form of vitamin D produced in the body as a result of direct sunlight — without the risk of unprotected UVB exposure. Because Vitamin D is fat-soluble, we include certified organic olive oil as a healthy fat source for better absorption.
