Vitamin D is inadequate in many individuals and daily need appears to
be higher than previously thought. Vitamin D's role in calcium
metabolism and bone health is well known. However, it has many other
important physiologic roles that are not as well appreciated. Vitamin D
receptors are widely distributed in the body, including colon,
prostate, breast and ovary, where it acts to inhibits the excessive
growth of body cells and tissues and helps cells mature normally.
Adequate amounts of vitamin D, an essential, fat-soluble vitamin, come
from consistent exposure to sunshine and are difficult to obtain from
dietary sources. Postmenopausal women, older individuals, and those
with malabsorption, limited sun exposure, or certain illnesses may need
higher intakes of vitamin D. Vitamin D3, the naturally-occurring form,
is supplied in high-potency amount of 1,000 I.U. per capsule for those
needing to conveniently augment dietary intake. A daily vitamin D3
intake of 1,000 to 2,000 units, an amount shown to be safe and
effective by clinical studies, is now advised by many experts.
Suggested Use: 1 capsule daily with food
