    Product Description

    Vitamin D-3

    Vitamin D3 provides Vitamin D3 or cholecalciferol, which is the natural form of vitamin D. Vitamin D is unique in that it is both obtained from dietary sources and produced by the exposure of skin to sunlight. It is also unique in that it has the characteristics of both a vitamin and a hormone:a substance produced in one tissue, affecting another, with its production controlled by an internal feedback loop. Vitamin D is fat-soluble and is stored in the liver and tissues. Individuals with darker skin pigmentation produce vitamin D less efficiently than light-skinned individuals and its production tends to diminish with aging. Diseases of the liver, pancreas, intestines,and gall bladder, which interfere with fat absorption, may reduce vitamin D assimilation. Certain anti-convulsive drugs also may cause vitamin D deficiency.

    Vitamin D is essential for proper mineral absorption. It promotes calcium and phosphorus absorption in the intestines, balances their deposition in the bones, and is involved in regulating calcium excretion by the kidneys.

    Vitamin D deficiency, even in the presence of adequate calcium may result in soft teeth and bones (rickets).

    Vitamin D is required for maintenance of muscle and nerve tone, including the heart, by regulating cell permeability and blood calcium levels. Insulin secretion and blood sugar regulation may also be effected by vitamin D.

    Research indicates that vitamin D plays important roles in the healthy functioning of the immune system, reproductive system, and thyroid. Additional actions of vitamin D are being identified on a regular basis; vitamin D receptors are located in virtually all of the tissue types in the body.

    Vitamin D deficiency may be common among people living in northern latitudes and those who dramatically limit their sun exposure (i.e. due on skin cancer risk). A young, healthy, fair-skinned person with a full day of sun exposure may produce 10,000 I.U. of vitamin D, while the elderly may produce insufficient vitamin D even with significant sun exposure. A recent estimate of the safe upper limit for Vitamin D supplementation is 10,000 I.U.daily.

    Vitamin D deficiency is a suspected causative factor in the development of osteoporosis, hip fractures, arthritis, and high blood pressure among the elderly. Recent research indicates that there may be a reduced incidence of cancers of the colon, rectum, breast, ovary, and prostate in individuals who maintain a high-normal blood level of vitamin D. Take Vitamin D3 5000 as a dietary supplement, one capsule daily. Consider reducing supplementation by skipping days during times of abundant sun exposure.
