Pure Encapsulations Vitamin D3, 1,000 iu -120 Veg Capsules

Vitamin D levels have been shown to decline with age, due primarily to a reduction in either absorption or metabolism by the liver. Decreased exposure to sunlight, a vegetarian diet, or a low intake of vitamin D fortified foods also play a role in inadequate vitamin D levels. Vitamin D promotes intestinal calcium and phosphorous absorption and reduces urinary calcium loss, essential mechanisms for maintaining proper calcium levels in the body and for healthy bone composition. Clinical studies involving vitamin D supplementation suggest the importance of vitamin D in addition to calcium for bone health. Vitamin D supplementation alone may also support bone health. Vitamin D may also provide cardiovascular support for some individuals, which may be attributed to its effect on calcium metabolism or possibly by helping to maintain healthy plasma renin function. A role for vitamin D in supporting colon health by promoting healthy cellular function has also been suggested. Vitamin D is also believed to provide general cellular support potential, including for the breast and prostate, in part by helping to maintain healthy angiogenesis balance, supporting immune cell activity and maintaining healthy cell metabolism. Preliminary evidence suggests that vitamin D may also play a role in maintaining healthy glucose metabolism, since vitamin D receptors are present on the islet cells of the pancreas.
