5000 iu per capsule!
Vitamin D is a fat soluble
vitamin that is found in food and can also be made in your
body after exposure to ultraviolet (UV) rays from the sun.
Sunshine is a significant source of vitamin D because UV rays
from sunlight trigger vitamin D synthesis in the skin
Helps in absorption of elemental
calcium. RecommenD for users of coral calcium products. A 2
month supply in every bottle.
Most brands on the market
on contain 200 to 400 iu per capsule. Our 5000 iu is a super
value.
The major biologic function of vitamin D is to maintain normal blood levels
of calcium and phosphorus.
By promoting calcium absorption, vitamin D helps to form and maintain strong
bones. Vitamin D also works in concert with a number of other vitamins, minerals,
and hormones to promote bone mineralization. Without vitamin D, bones can become
thin, brittle, or misshapen. Vitamin D sufficiency prevents rickets in children
and osteomalacia in adults, two forms of skeletal diseases that weaken bones.
Suggested Use: 1 capsule daily
as a dietary supplement, or as Directed by your health care
provider.
Caution: If pregnant or nursing, consult your physician before using any supplements. Keep all supplements out of reach of children. Keep tightly closed.
Importance Of Vitamin D
Nutrient Deficiencies are
usually the result of dietary inadequacy, impaired absorption
and utilization, increased requirement, or increased excretion
(loss). A deficiency of vitamin D can occur:
-
when usual intake is below recommended levels
-
when there is limited exposure to sunlight
-
when the kidney cannot convert vitamin D to its active
hormone form
-
when someone cannot adequately absorb vitamin D from the
digestive tract
Vitamin D Deficient diets are associated with milk allergy, lactose intolerance,
and strict vegetarianism. Infants fed only breast milk also receive insufficient
amounts of vitamin D unless they also receive appropriate levels of vitamin
D supplementation
Dosage Found in Multivitamins Reduces Risk by 40%

An abundance of vitamin D
seems to help cut the odds of developing multiple sclerosis,
according to a study of stored blood samples from more than
7 million members of the U.S. military.
Jan. 12, 2004 - Evidence continues
to mount showing that a little vitamin D can do a lot of good.
The latest: A new study indicating that women who get doses
typically found in daily multivitamin supplements - of at least
400 international units - are 40% less likely to develop multiple
sclerosis compared with those taking over-the-counter supplements.
This finding, by a team of Harvard researchers and published in this week's issue of Neurology ,
comes just a few days after another study links Vitamin D deficiency
with an increased risk of rheumatoid arthritis. Like MS, rheumatoid
arthritis is an autoimmune disorder, a classification for some
80 different ailments in which the immune system mistakenly
attacks healthy tissue and organs in the body.
"We've known for some time
that vitamin D can affect function of the immune system, which
could explain why it seems beneficial to both of these autoimmune
conditions," says Kassandra Munger, MSc, of Harvard School of Public Health, a researcher for this study. "In animal studies, vitamin D Vitamins has been shown to suppress the autoimmune response in rats with a disorder very similar to MS."
Other recent studies link
Vitamin D deficiency to a greater risk of other ailments, including
heart disease, diabetes, unexplained muscle and joint pain,
and various forms of cancer. As with MS and other autoimmune
diseases, the secret may be in how this nutrient affects cell
activity.
"We need adequate amounts
of Vitamin D to keep cell growth and activity in check," says Michael Holick, MD, PhD, director of the Vitamin D Research Lab at Boston University Medical Center and considered by many to be the nation's leading authority on this vitamin. When the body is deficient in this crucial nutrient - best known for coming from sunlight - cells go haywire, become overly active or multiplying too quickly.
That's why the new finding doesn't surprise Holick, who wasn't involved in it. "It's been well-known that if you live at a higher altitude, where there's less sun exposure, you're at a higher risk of developing MS," he tells WebMD. Conversely, if you live in a sunny climate where vitamin D Vitamins can be easily absorbed year-round from sunlight for your first 10 years, "it imprints on you a decreased MS risk that can last a lifetime," Holick explains.
Munger's results are encouraging
because 20% to 80% of Americans may already be vitamin D Vitamins
deficient - at least during winter months. While as little
as 10 minutes of sun exposure on bare, unprotected skin can
prevent Deficiencies in warm and sunny months, it's virtually
impossible for most Americans to get that kind of exposure
this time of year.
Good food sources of vitamin D include:
• Fortified milk, 8 ounces contains approximately 100 IU of Vitamin D Vitamins
• Cod liver oil, 1 tablespoon contains approximately 1300 IU of vitamin D
• Cold-water fish such as salmon and herring, 3 ounces contains approximately 400 to 750 IU of Vitamin D Vitamins respectively
However, Munger says that
no matter where they lived (which could help determine their
Vitamin D exposure from sunlight), her study's participants
who got the highest intake of vitamin D from supplements had
the lowest risk of developing MS. Interestingly, those whose
Vitamin D came only from food, but not pills, had
no such decreased risk - no matter their intake.
Her study is part of the ongoing
Nurses' Health Study that has been tracking, for nearly 20
years, how various nutritional and lifestyle habits impact
health in some 190,000 women. It's the latest evidence to show
that something as simple as taking a multivitamin can offer
significant protection against a disease that afflicts some
400,000 Americans. Although the cause of MS is unknown, experts
believe it is partly an autoimmune disease that causes lesions
within the brain and spinal cord, slowing or blocking nerve
signals that control muscle coordination, visual sensation,
and other vital functions.
"Very few of the women in
our study were taking 'straight' Vitamin D supplements," Munger tells WebMD. "Mostly, they got these benefits from a regular multivitamin pill with the standard dosage of vitamin D. While it's too early to conclusively recommend taking multivitamins to prevent MS, certainly many people have advocated taking them for other reasons."
Holick has long recommended that most Americans - especially those living in cold or gray winter climates - take a multivitamin and an
additional vitamin D supplement between 400 and 1,000 IUs to
prevent possible deficiencies. "My guess is that these study participants probably consumed closer to 600 IUs in their multivitamins," he tells WebMD.
"We found that taking vitamin
supplements of 1,000 IUs caused changes in blood chemistry
that indicated positive effects for multiple sclerosis patients
- basically, it reduced their symptoms," says
Margherita Cantorna, PhD, assistant professor of nutrition
at Penn State University who headed that study. A longtime
researcher on how vitamin D impacts multiple sclerosis, she
was not involveD in Mungers study, but like Holick, says she
isn't surprised by the findings.
"It's pretty clear that when
theres vitamin d Deficiency, there's a greater tendency
for cells that cause autoimmune problems to come out in those
genetically susceptible people," Cantorna tells WebMD. "it's
about pretty clear that taking supplemental vitamin D Vitamins
is a good idea. You're hard-pressed to get enough vitamn D
solely from food or from sunlight in the winter."
