How much vitamin D is enough? Report sets new levels - Megadoses of 'sunshine vitamin' don't...

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.

The ‘truth’ is that there is no one set amount that is ‘correct’ for everybody.

S.510 means that homegrown food can be “regulated.”

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?

The taxpayers paid for this review by the Institute of Medicine, the health arm of the National Academy of Sciences.
