Vitamin D has been associated with bone health, protection against diabetes, multiple sclerosis, cancer, heart disease, and depression. A vitamin not easily obtained from a food source, just 15 minutes out in the sun can give an individual a daily dose. Not so easy for those in northern latitudes where a supplement may be necessary. The Journal of American Medical Association has several articles on the benefits of Vitamin D from curing the common cold to regenerating tissue function.
