Natures Sunshine Vitamin D3. Perhaps the most well known function of Vitamin D is to retain calcium absorption and metabolism for bone health. It promotes intestinal absorption of calcium and phosphorus, facilitates calcium transport and reduces urinary calcium loss in order to keep calcium in the body and spare calcium stores in the bones. Vitamin D also promotes calcium deposition in bones and is required for the proper utilization of magnesium. Very few foods contain vitamin D. As a result, a varying percentage of people are deficient in this vitamin at any time, with this percentage being higher in winter, among the elderly or obese, in sun deprived individuals, in dark skinned people (heavy melanin effectively blocks skin synthesis of Vitamin D) and in populations living in more poleward regions with lower sunlight exposure. 60 tablets
