There was an earlier post about vitamin D and I so I thought the
folowing information would be of use. Merck & Co., Inc. has announced
that the U.S. Food and Drug Administration (FDA) has approved FOSAMAX
PLUS D(TM) (alendronate sodium/cholecalciferol), a single once-weekly
tablet containing 70 mg FOSAMAX(R) (alendronate sodium) and 2800 IU
vitamin D3, representing seven days worth of 400 IU of vitamin D. (The
recommended intake of vitamin D is 400-800 IU daily). FOSAMAX has been
demonstrated to reduce the risk of both hip and spine fractures in
postmenopausal women with osteoporosis and is now the only
bisphosphonate with the added benefit of a weekly dose of vitamin D.

Maintaining adequate levels of vitamin D is necessary for the
development of strong bones because it helps increase the intestinal
absorption of calcium. Vitamin D insufficiency is associated with
reduced calcium absorption, bone loss and increased risk of fracture.
Patients at increased risk for vitamin D insufficiency (e.g., those who
are nursing-home bound, chronically ill, over the age of 70 years) and
with gastrointestinal malabsorption syndromes should receive vitamin D
supplementation in addition to that provided in FOSAMAX PLUS D.

FOSAMAX PLUS D is indicated for the treatment of osteoporosis in
postmenopausal women. For the treatment of osteoporosis, FOSAMAX PLUS D
increases bone mass and reduces the incidence of fracture, including
those of the hip and spine. FOSAMAX PLUS D is also indicated to
increase bone mass in men with osteoporosis.

FOSAMAX PLUS D, like other bisphosphonate containing products, should
be used with caution in people with certain stomach or digestive
problems. FOSAMAX PLUS D should not be used if the patient has certain
disorders of the esophagus that delay emptying or if the patient is
unable to stand or sit upright for at least 30 minutes. In addition,
FOSAMAX PLUS D should not be used in patients with severe kidney
disease or low levels of calcium in their blood, in patients who are
allergic to FOSAMAX PLUS D or in patients who are pregnant or nursing.
FOSAMAX PLUS D alone should not be used to treat vitamin D deficiency.

Many physicians and patients frequently are unaware of the importance
of vitamin D in bone health. Given its effect on calcium absorption,
vitamin D insufficiency is an important medical concern for patients
with osteoporosis, as it can lead to bone loss and an increased risk of
fracture.

Vitamin D is obtained from two sources: sunlight and diet. The skin
manufactures the majority of the body's vitamin D after direct exposure
to sunlight but as adults age the ability to make vitamin D through the
skin diminishes. Avoiding sun exposure or using sunscreen can also
limit a person's production of vitamin D. Vitamin D can also come from
the diet but there are limited dietary sources that contain the
nutrient. Good dietary sources include fatty fish (e.g., salmon),
vitamin D fortified milk and orange juice. However, for many people,
dietary sources alone are not enough. For example, one must drink four
eight ounce glasses of milk to receive 400 IU of vitamin D.

According to an analysis published in 2004 and based on the Third
National Health and Nutrition Examination Survey (NHANES III), a
majority of Americans are not consuming enough vitamin D. The study
estimated that over 70% of women age 51-70 and almost 90% of women over
70 are not getting an adequate intake of vitamin D from food and
supplements. This analysis was based on the adequate intake, as defined
by the National Institute of Health's Institute of Medicine, of 400 IU
per day for women age 51-70 and 600 IU per day for women over 70 years.
Other organizations, such as the National Osteoporosis Foundation
(NOF), recommend vitamin D intake of up to 800 IU per day. As a
treatment for osteoporosis in postmenopausal women, FOSAMAX PLUS D
offers 2800 IU vitamin D, representing seven days worth of 400 IU of
vitamin D.

I now routinely check 25-OH Vit D levels and if below 30ng/ml would
suggest treatment. I use the repalacement regime as devised by Michael
Holick MD.

Several comments.

First the Fosamax contain too little vitamin D if
it is seen as the sole source of supplemental vitamin D.
I'd suggest 5600 IU (140 mcg) per week would
be the barebones minimum as a maintenance
dose and 7000 IU (175 mg) per week is a reasonable choice.
Perhaps they are assuming concurrent use of a multiple vitamin
and being ultra-conservative?

Personally I agree with Vieth that 4000 IU per day during the darker
months of the year or for living entirely indoors 4000 IU all year round
is a better choice.

30 ng/ml is right around 80 nmol/L.
Reasonable.
Far better than waiting until 40 nmol/L.

Just a word to the wise. It is my opinion (and I think I've expressed it
here before) that it is not a good idea to blindly take large doses of
Vitamin D (or anything for that matter). A good endocrinologist can
order tests to see if your body needs vitamin D supplementation and if
so, how much. Your body is supposed to get plenty of it by itself from
sunlight during months that are not winter months.

Yes, Larry we've disagreed before.
(You top posted so I top posted.)

Be it known that Ronald Vieth, Michael F. Holick,
B. Dawson-Hughes, B.W. Hollis, C. L. Wagner,
C.M. Weaver, and J.C. Fleet generally seem to
agree with my position.

Recall that if you live in Brazil and get out in
the sun, your serum 25 (OH) vitamin D3
levels will be similar to a person who is taking
4000 IU (100 mcg) and not get any meaningful sun.
Many people don't get strong enough sun
to yield meaningful amounts of vitamin D3 due
to work schedules, smog, dark skin, seasons,
and confinement.

In younger adults an exposure of 15% of
skin area for 1/3 a minimal erththemal dose
yeilds 1000 IU (25 mcg) during the summer.
A whole body exposure for 10 to 15 minutes
in the midday sun of summer yeilds a dose
of 15 000 IU (375 mcg). On the other
hand in the late fall depending on latitude such an
exposure to the midday sun will yeild no
meaningful amounts of vitamin D3. In the
elderly, the synthesis of vitamin D3 can be
cut by 75%.

Understand also that while a normal serum calcium level
can not be used to diagnosis a vitamin D deficiency,
it can be used to used to check for hypervitaminosis
as the serum calcium would be elevated in such a
case.

An as far as a good endocrinologist goes, I suggest
if one is educated, one is better off reading up
on the topic themselves and getting their lab
results from a lower cost GP at least at times.
Endocrinology isn't rocket science ;-)
And good ones occur at a rate of about 1 in 10
at best, IMO, on the basis of a position poll
among other things.

The body DOES NOT accumulate sufficient
stores to maintain sufficient 25 (OH) vitamin D3
to yield enough 1,25 (OH)2 vitamin D3 to
prevent a rise in PTH and the liberation of
calcium from the bones. Serum levels of
less than 80 nmol/L of 25 (OH) vitamin D3
have an inverse relationship to PTH levels.
Indeed, some have suggested even this value
is too low for fully reducing PTH levels.
Granted, I've seen the threshold for
sufficiency set at 50 nmol/L and even
lower by some.

And finally it takes 4000 IU (100 mcg)
in a lactating woman to render her
beast milk an adequate source of
vitamin D. Or it would seem 20
minutes in the sun with 10 minutes
exposure for both sides in a Bikini
swim suit.

From: Larry on
John,

You can spout off as many apparent references as you want to support
your position to overdose on vitamin D. I know people who take 1000s of
mgs of vitamin C per day and think it does them some incremental good
but don't understand that the human body just excretes it all out. But
.... as with any substance that you take into your body ... especially in
quantities ... it makes good common sense to seek the opinion of your
doctor. Some osteoporotic people need vitamin D supplementation, some
don't. Some osteoporotic people need calcium supplementation, some
don't. Some heart patients need to take statins, some don't. And to
think that you can derive the best answer for your body by reading
references on the internet is sheer silliness.

Vitamin D happens to be a component that can be tested for in the serum.
There is absolutely no good reason to assume that you need it without
being tested to make that determination and without seeking out the
advice of a qualified physician.

That is my opinion. You are certainly welcome to yours, and I respect
that. But I think it is wrong to encourage people to blindly ingest
substances into their body over the internet ... when it makes much
better sense to seek out the opinion of a physician. If you don't like
his opinion ... seek out another and another. If you can find one that
recommends such high levels and only having one (or however many)
satisfies you, go ahead and have a party if you must.

>>>>increase bone mass in men with osteoporosis.

>>>>FOSAMAX PLUS D, like other bisphosphonate containing products, should
>>>>be used with caution in people with certain stomach or digestive
>>>>problems. FOSAMAX PLUS D should not be used if the patient has certain
>>>>disorders of the esophagus that delay emptying or if the patient is

>>>>vitamin D fortified milk and orange juice. However, for many people,
>>>>dietary sources alone are not enough. For example, one must drink four
>>>>eight ounce glasses of milk to receive 400 IU of vitamin D.

>>>>According to an analysis published in 2004 and based on the Third
>>>>National Health and Nutrition Examination Survey (NHANES III), a

>>>>estimated that over 70% of women age 51-70 and almost 90% of women over
>>>>70 are not getting an adequate intake of vitamin D from food and

>>>Several comments.
>>>
>>>First the Fosamax contain too little vitamin D if
>>>it is seen as the sole source of supplemental vitamin D.
>>>I'd suggest 5600 IU (140 mcg) per week would
>>>be the barebones minimum as a maintenance
>>>dose and 7000 IU (175 mg) per week is a reasonable choice.
>>>Perhaps they are assuming concurrent use of a multiple vitamin
>>>and being ultra-conservative?
>>>
>>>Personally I agree with Vieth that 4000 IU per day during the darker
>>>months of the year or for living entirely indoors 4000 IU all year round
>>>is a better choice.
>>>
>>>30 ng/ml is right around 80 nmol/L.
>>>Reasonable.
>>>Far better than waiting until 40 nmol/L.
