And I am supposed to believe that "....it would seem it's not a given." because WHY?
Last fall I noticed lots of those "health-infomercials" had the man who runs the Vitamin D Council website, and he'd be interviewed for an hour chatting all about how excellent HIS Vitamin D formua was, because it had all sorts of minerals that Vitamin D allegedly needs to work.
Anyway, this whole Vitamin D thing apparently has massive numbers of True Believers online, and any questioning about specifics gets either no answers or vague, oh don't be silly -- it's common sense trite answers.
It's similar to the global warming believers.
Now for years I've read that it's SAFE to take large amounts of Vitamin D for up to thirty days.
HOW do these cyberstrangers KNOW that it is safe for ALL netizens to down 30,000 IUs of Vitamin D for 30 days??????????
Huh?
The True Believers then fall back upon their ONLY real answer -- go get a test.
I thought the Vitamin D test is SO inconclusive that insurance companies won't cover it.
So ... WHY am I supposed to get this test??
LOL

“Vitamin D insufficiency in southern Arizona”
...Conclusion: Despite residing in a region with high chronic sun exposure, adults in southern Arizona are commonly deficient in vitamin D, particularly blacks and Hispanics.
thanks, but i take my medical advice from MEDICAL PROFESSIONALS, like my internist. her advice happens to be in sync with this article.
I think we can all agree that extraordinary and improbable claims dilute what is otherwise a reasonable message.
However, the underlying truth is that *by our current measure*, Americans, for likely many reasons, have an insufficiency of Vitamin D available in their system, which is a strong contributing factor to disease.
As an aside, I would like to mention that this is not a unique situation in US history. One of the truly shameful legacies of American medical history is the conclusion of the great Pellagra (niacin (B3) deficiency) epidemic that ravaged the American South in the early 20th Century.
Caused to some extent by the Civil War Reconstruction, large numbers of people lived on a diet almost exclusively of corn grits which had not been alkalized in lime, which leaves them a poor source of Niacin, as well as a low protein diet. While the body could have converted more of the corn for Niacin, the priority is for conversion to protein in its dietary absence.
So each Spring, with the return of the sun, which increased Niacin metabolism, there would be an outbreak of Pellagra, affecting tens of thousands in terrible ways.
Eventually, however, it was discovered that a simple supplement of inexpensive Brewer’s Yeast would prevent Pellagra, so throughout the South, Brewer’s Yeast pills were provided to all white schoolchildren.
But no effort was made to provide it to black children. This meant that within a year or two, Pellagra became an exclusively “black” disease. Only later was this injustice corrected.
To this day, Pellagra is common in Africa, Mexico, Indonesia, and China. In affluent societies, a majority of patients with clinical pellagra are poor, homeless, alcohol dependent, or psychiatric patients who refuse food.

Have you read the material at the linked sites I gave you? That’s first.
More good news....
I just assumed that you’re an idiot due to the quality of your posts. My bad.
Very good info from you. I am in the correct zone and try to get the sun around noon.
Use of the word, *can* or *may*.
Is not the same as *does always*.
Absolutely right. And we should instead refer to advice from a self claimed “molecular biologist” instead of zillions of doctors. “Pajamas” media was reporting on exactly what I’ve found in researching myself. They also had numerous links to doctors research and studies. I think some people like to puff out their chests and just be contrary. Whatever, I know from personal experience that Vitamin D3 is like a miracle drug.
Does your internist claims that giving more vitamin D will reduce your risks of most major disease by 50% to 80%, as this article does?
Red queen logic. Before you can substantiate your bizarre and unsubstantiated claims I must first read more bizarre and unsubstantiated claims?
Sorry but you have done absolutely nothing to substantiate the ludicrous claim that ‘all you have to do’ to “reduce your risk of most major diseases by 50-80%” is to get more vitamin D.
And roofers in South Florida have elevated risks of skin cancer, and do not have a majorly reduced risk of major disease- Another bizarre and ludicrous clam that is also absolutely unsubstantiated.
IF Vitamin D3 were a universal panacea, would not peoples from tropical locations all live long healthy lives with no incidence of ANY of those diseases?
Those people can also be vitamin D deficient. Dark skin can take many times longer to convert sunlight to vitamin D. Rainy seasons can block sunlight for months. People try to avoid exposure to direct midday sunlight.
And people who lived in tropical locations with lighter skin would have reduced rates of most major diseases by 50-80%. This is obviously not the case.
Moreover the synthesis of vitamin D is a genetically regulated process.
Why would the body shut down full production of vitamin D from sunlight if elevated vitamin D levels were such a universal panacea?
You wouldn’t say that if you had read the articles and studies on that website.
Since you refuse to educate yourself further there is no point in discussing this with you.
And here I thought it was just teen hormones, but to replicate that decades later doesn't make sense - UNLESS if it is the Vitamin D3 that provokes such a strange mental state, accompanied by sore joints, aching muscles; wide awake insomnia fluctuating with periods of almost narcoleptic need to sleeeeeep for many many many hours at a time.
No wonder the eskimos and probably the sa'ami, too, avoided the polar bear liver -- they probably didn't want the excess Vitamin D -- not the "A" as previously thought.
So this stuff has a half life of 140 days?? WHAT does that mean? Relief in 3 months?
I’ll be more clear: If you had bothered to read the reports on that website, you would have found some limited support for your position.
But your intransigence blocks you from learning, making you your own victim.
Please read post 43 more carefully.
Aruanan didn't say that Vitamin D had a half-life in the body of 140 days, he said it was Vitamin A that had that half-life. Vitamin D has a half-life of approximately three weeks.
aruanan:Contrary to your claim that the body has no way to excrete excess vitamin D, there is no way for the body to excrete any vitamin taken to excess other than the normal means of excretion. Vitamin D is excreted principally in bile as well as metabolised to water-soluble metabolites that are excreted in the urine. Because of this, the half-life of vitamin D in the liver is approximately 3 weeks (compare this to the vitamin A half-life of about 140 days). This is said to underscore the need for frequent replenishment of the body's supply.
