How much vitamin D is enough? Report sets new levels - Megadoses of 'sunshine vitamin' don't...
MSNBC ^ | November 30, 2010 | Robert Bazell & AP

Megadoses of 'sunshine vitamin' don't prevent disease, may be harmful

WASHINGTON — For the past few years vitamin D has been the "it" vitamin, with studies wildly trumpeting the supplement's role in strengthening bones, reducing the risk of some cancers, heart disease, along with fighting autoimmune diseases and diabetes. But long-awaited new dietary guidelines say there's no proof that megadoses of the "sunshine vitamin" prevent cancer, diabetes or other conditions.

While some people will need a bit more vitamin D than they're already getting, some studies suggest that too much could actually cause some kinds of cancer, according to the panel of experts at the prestigious Institute of Medicine, the health arm of the National Academy of Sciences.

"More is not necessarily better," cautioned Dr. Joann Manson of Harvard Medical School, who co-authored the Institute of Medicine's report being released Tuesday...

A good rule of thumb with anything is keep doubling the dose until your urine is saturated with bright, red, healthy blood.

So who paid for the study? Just asking.

I don’t know about Vitamin D, but the “authorities” seem all hot and bothered to take away our vitamins and healthy foods.

Doubt everything they say.

The Government consistently lies regarding our needs re: Vitamins, supplements, Aminos, probiotics etc. They are in lobbyist beds with Monsanto (frankenfood) and big pharma.

800 mgs. absolutely!
SB510 today proves that we will will no longer be eating real food unless we grow it and cultivate it ourselves.

These people are all making money off of trying to zombitize us.

Scanners GMO corn, cotton, soy,monsanto..you name it...we are so screwed.

FReepmail me if you want on or off the diabetes ping list.

The vitamin D blood test results are not reported as nanograms(ng). They usually reported as nanograms per deciliter(dl), i.e. concentration.

It is useful to recall that the minimum daily requirement was set on the basis of the minimum needed to prevent rickets.

If that's your criterion for health, fine. The probablitity however is that higher doses will have a beneficial effect on all sorts of functions never before studied systematically.

An arbitrary dose of around 1000 mg daily is a fair measure which has no known negative side effects.

All these vitamin reports come out in order for our government to start taking away peoples’ ability to get vitamins in certain dose levels.

You can kill yourself with your vitamins. We will protect you from yourself.

I can take a whole bottle full of vitamin c and probably have an acidic stomach. If I take a whole bottle of tylenol I’m dead.

Yup you know we stupid drone citizens can’t be trusted to research herbs and vitamins and determine what doses we want to take. Nope gotta have a doctor tell us and prescribe what THEY think is good for us.

For Christmas, Lord, I want every bureaucrat and government subsidized researchers and scientists to just go away. We really must export them all to countries that do not have the “benefit” of their expertise. While we’re at it Lord they can have all our lawyers and environmental extremists.

The amount in vitmamin D supplements or in multivitamins is usually expressed as International Units(IU).

Didn’t an NIH study about 10 years ago prove that 2,000 IU / day resulted in a marked decline in cancer rates?

Maybe Vit D is proving to reduce/prevent cancer and THAT is a problem for pharma. Which is more fun, taking Vit D or chemo? Which costs more and employs more?

Didn't another report come out today praising Vit D?

**************

Probably; that would explain why the brand I’m buying has capsules with 2000 IU each of “D” -—

Recommendations change all the time. Soy was good.......until it wasn’t — Vitamin E — same thing — take this, no, don’t take it — MAKE UP YOUR MINDS, EXPERTS!

I’m so sick of this I could spit nails!

It is not how much you choose to take; it is how much your circulating blood level is. If you are seriously below the norm, you DO need supplements.

I question this study until I read more. I know people who take Vitamin D and can’t get their levels anywhere near normal. That means they are using what they are ingesting.

Since Vitamin D is stored in fat, it is not until the fat stores are saturated that one can get into trouble; the circulating blood level can then rise and dramatically. That’s why I’d never recommend messing with taking fat soluble vitamins—like D—unless they are being measured and yes, by a good lab.

My wife has been a primary school teacher for 30+ years. Until last school year she has always gotten her flu shot and has brought home every flu and cold that the kids have brought to school. Last year when school started she commenced to taking 10k iu a day of D-3 and did not get any flu shot. She did not bring home any respiratory maladies though her classroom was full of it for at least a third of the school year. She repeated for this year and has brought no illnesses home so far. I take the stuff, too. I work at night and see little sun, even in the summer. I have had none of these maladies, either but then never did get them much, anyway.

My Nephrologist actually measures my level once a year and I have come up from below normal to mid-range on 4000 - 5000iu a day and I live where we have sunshine 300 days a year... yet I was below normal.

I had a chronic cough that would settle in for about 6 months of every year. Nothing would cure it except time - until it came back the following year. Then one year I started taking 8000iu of D every day and it was gone in a week. The next year when I felt it coming back after a cold, I started the high dosage D again and it went away in a week. I cut back to 2000iu every day but the cough (that plagued me annually for about 15 years) has not come back.

So I don't care about their stupid studies - it worked for me.

Glad to hear you have it tested. I am not surprised by your comments. I believe that studies showed that a good portion of Minnesotans had levels close to half normal (long winters; low sun; shortened summer). By contrast, we are now all indoctrinated to slather on SPF sunblock 4 million if we go into the sun. Since UV irradiation is needed to convert the precursor to the active vitamin, people are getting deficient even in sunny climes.

I know docs who now prescribe Vitamin D supplements routinely to every woman over 60 (plus calcium). I believe the evidence shows that it helps stem later osteoporosis.

Point is, if you know your circulating level, and a doctor is advising, I believe it is of great benefit. The old standard value was 400 IU per day and that is what was derived from fortified milk. I believe that is too low personally and am glad the article has upped the level to at least 800. I am still big on having people tested to see if their levels are too low.

Yes (and the very example is ludicrous, but government would “protect” us from ourselves you know) but it would not kill me. Whole bottle of tylenol would.

I can tell a significant difference in how I don’t catch stuff since I have been tested and brought the levels up in my blood stream. You mentioned osteo, I had my bone density testing done last year and my bones are equivalent of a woman about half my age, as a non-drinker, non-smoker and I don’t drink carbonated drinks (high in phosphorus as you probably know) it seems I am doing something right with my supplement regimen.

This is poor advice. What is needed is for anyone concerned to go in and have your vitamin D levels tested. Sometimes it is hard to get vitamin D from either sun or supplements, and under 40 (units?) means you are far more likely to get sick.

I was taking around 2000 units a day, plus it was warm fall and I was getting outside a little every day. I got tested and my level was 20. That is unacceptable. I now am taking 10,000 units a day and will go back for another test.

Seriously, telling people how much to take is a bit ridiculous, if a normal healthy woman is taking 2000 units a day and still deficient per a blood test. If that “prestigious” institute wanted to be truly conscientious it would ask people to be tested to know their proper dose of supplementation.

I was on 5000 iu a day, but decided 2000 was better for me.

FWIW, I have been very healthy lately, even after being around a sick grandchild.....daily visits to dad in hospital..... assisted living & rehab facilities...and the public in general with coughs and sneezes....

....just saying

I also take 2 tsp of fish oil per day.

The problem with determining the daily requirements for different vitamins and nutrients is with doing controlled experiments - you can’t deprive people of food.

There is a pattern here.

Every time a benefit is demonstrated from a substance, whatever it may be, the establishment scammers publish a foolish ‘study’ to ‘debunk’ it.

Are people really stupid enough to listen to these failures telling them what works doesn’t work?

No credible scientific study has ever shown any benefit from an unfermented soy product.

Fermented soy, such as natto, or fermented tofu has many benefits.
