 Vitamin D is critical for normal calcium metabolism and plays a vital role in maintaining bone and muscle health. The vitamin is produced naturally in the skin as part of a reaction involving sunlight but is also consumed in the diet. Many people are vitamin D deficient because they shun vitamin D-fortified dairy products and don't get much outdoor activity.

 A review of literature by Lisa Ceglia from the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston concluded that adequate vitamin D levels were important in muscle strength, power, speed, jump height, and preventing falls. Insuring adequate vitamin D levels is critical for maximizing muscle and bone health throughout life. (Current Opinion in Clinical Nutrition and Metabolic Care, 12: 628-633, 2009)
