Vitamin D has long been known for its role in bone health. Before the recent Institute of Medicine (IOM) guidelines, there were conflicting messages about its other benefits. The IOM experts' exhaustive review of the evidence maintained the importance of calcium and vitamin D in promoting bone growth and maintenance. New Daily Reference Intakes were recommended. The report indicated that individuals seem to get meaningful amounts of vitamin D from sun exposure. Higher levels were not shown to provide a greater benefit. Extension professionals have the capacity to train professionals and consumers about the new vitamin D reference intakes.
