The following is the introduction of this article: Vitamin D is the only vitamin that is free. It can be easily obtained from exposure to sunlight and yet more than 60% of Americans are Vitamin D deficient (Ginde et al., 2009; Bones, Vitamin D, and Calcium, n.d). The significance of Vitamin D can’t be emphasized enough and is often overlooked. Some its profound effects are apparent in the prevention of various diseases such as cancer, multiple sclerosis, and cardiovascular disease et cetera. Many lives can be spared each year just by taking Vitamin D. From cancer alone, 23,000 deaths can be attributed each year to a lack of Vitamin D (Grant, 2002; Reichrath, 2008). Vitamin D deficiency in America is an epidemic that needs to be addressed.
