Naturally derived vitamin D3.

Vitamin D3 enhances calcium absorption and retention, a key nutritional role in supporting healthy bones. This unique nutrient may also play a potential role in cardiovascular, colon and cellular health. 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 rich foods also play a role in inadequate vitamin D levels.

In 1941, the recommended dietary allowance (RDA) for vitamin D was set at 400 iu per day in order to prevent the incidence of rickets. Today, scientists worldwide have described an urgent need to raise the daily recommendation to as much as 1,000-2,000 iu per day. These levels are believed to be optimal for supporting bone, cellular, immune, nerve, cognitive and vascular health. Experts also argue the need to increase the upper limit from 2,000 iu to 10,000 iu per day.

The vitamin D3 found in this supplement from Pure Encapsulations is derived from the cholesterol in lanolin, the fat found in wool. The hypoallergenic plant fiber used to make the capsules is derived from pine cellulose.

Uses for Vitamin D3

Bone Health: 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.

Cardiovascular Support: 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.

Cellular Health: Studies suggest vitamin D supports colon health by promoting healthy cellular function. Vitamin D is also believed to provide general cellular support potential, including breast and prostate cells, 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.

Frequently Asked Questions

Q. What is the difference between Vitamin D2 and Vitamin D3?

A. Vitamin D3 is the naturally occurring form of vitamin D synthesized in humans. Research indicates that plant-derived vitamin D2 is metabolized differently than vitamin D3. In fact, Vitamin D3 may be more than three times more effective than vitamin D2 in raising and maintaining serum D levels. In addition, its metabolites have more affinity for vitamin D-binding proteins in plasma. Pure Encapsulations products contain only vitamin D3.
