Jamieson Vitamin D 400 IU, 90 tabs

Vitamin D is known as the “sunshine vitamin” because ultraviolet light stimulates the skin, liver and kidneys to produce Vitamin D3. Fat-soluble, Vitamin D stimulates calcium absorption and regulates calcium concentration in the blood, promoting healthy bones, teeth and skin. Dietary deficiencies and lack of exposure to sunlight can lead to rickets, osteomalacia or osteoporosis. Jamieson uses only Vitamin D3, the nutrition industry’s premium-grade natural Vitamin D source.
