Your risk for vitamin d deficiency is greatest during the winter months. During the fall and winter north of the 37° latitude the angle of the sun with respect to the atmosphere is very steep. As a result much of the solar UV radiation that is key in the body’s natural process of Vitamin D3 synthesis is blocked.[1] In order to combat the skins inability to make Vitamin D in the fall and winter it is essential to supplement it with a topical lotion containing concentrated biologically active Vitamin D3. Topical Sun not only meets these requirements, the RHn delivery system insures that the Vitamin D3 is deliver into the skin where it is naturally found.
