Known as the “sunshine vitamin” because ultraviolet sunlight works with the skin, liver and kidneys to produce Vitamin D3, Vitamin D is a fat-soluble vitamin that stimulates calcium absorption and regulates calcium concentration levels in the blood, promoting healthy bones, teeth and skin. Deficiencies due to diet and lack of exposure to sunlight can lead to rickets, osteomalacia or osteoporosis.
