Vitamin D3
1000 IU, 250 capsules
Item No.
00251
Vitamin
D is necessary for
utilization of calcium and phosphorus and in many ways acts as a
hormone. The two
most important forms of vitamin
D are cholecalciferol (D3),
which is derived from our own cholesterol and ergocalciferol
(D2), a plant analogue derived from the diet. The
cholecalciferol supplied by the Life Extension Buyers Club is
synthetic, but its form is identical to that which is derived
from cholesterol and synthesized by sunlight on the skin.
Cholecalciferol Vitamin
D is essential for bone
growth and maintenance of bone density.
A dietary deficiency of
vitamin
D inhibits the production of
the protein that binds calcium in the intestines, so that
calcium cannot be absorbed, even if there is adequate intake.
Deficiencies of vitamin
D are often found in the
elderly and in women who have low intake of milk and receive
inadequate exposure to sunlight.
Vitamin D is potent
in minute quantities; one microgram of cholecalciferol has 40 IU
of vitamin
D activity.

Caution: |
|
Large doses (1400-2000 IU/day)
may cause hypercalcemia, a decrease in renal function, and
nephrocalcinosis. Monthly blood tests to monitor serum
calcium and parathyroid hormone levels should be done to
protect against vitamin
D3 toxicity. Those with underlying kidney disease should
avoid high doses of vitamin
D3. Although some research indicates that dosages up to
10,000 IU/day are safe, healthy people should stay below
2000 IU/day. |
