Sunday House Call has focused on the promising research and a greater understanding on the effects of Vitamin D. We have had principle investigators discuss its effects on reducing the rate of falls in the elderly, reducing the risk of colon and breast cancer recurrence, reduction of stress fractures in young women, its effects on retarding progression of macular degeneration and other studies have suggested that it can reduce the risk of MS. In each instance, these areas of research continue to support through evidence-based findings that vitamin D does more than help maintain bone strength and density. This is Vitamin D Awareness Month.
