Known as the “sunshine vitamin”, Vitamin D is an essential micronutrient aiding in the process for calcium absorption, strong bone development and building a healthy immune system. For those who have limited access to sunlight (i.e. the wintertime blues) or to reduce risks associated with unprotected Uva and Uvb exposure, our Sports Research Vitamin D3 formula delivers the exact same biologically active form of vitamin D produced in the body from direct sunlight. And because D3 is best taken with a fat, we added coconut Mct oil to our softgels so you can get more of what your body needs.
