FYI:
Even a dead clock is correct twice a day. You may wish to rethink your notion that the quality of the information transmitted is based entirely on the identity of the author and how much he is charging. For forty years American women were advised by their physicians that estrogen would reduce their chances of cancer and heart disease. It turns out that the estrogen did not help the heart disease and cause the cancer to grow faster. I believe that most of those physicians were paid a lot of money for the advice that hastened the death of hundreds of thousands of women.
Excess Vitamin D3? Almost everyone is deficient. I don’t believe in ALL my research...and it’s been alot...that I’ve seen any report on ANYONE having “excess” vitamin D3.
The reports are voluminous all over about this and the studies have repeatedly shown the benefits of this “hormone”.
“Most” people won’t be getting 15 minutes in sunshine in winter for months on end. And “most” people are innoculated into believing the sunscreen scare.
Feel free to believe what you want. I will be taking at least 4000 IUs daily. I am severely deficient and since doing this, my health has improved dramatically.
During flu season this year october to april I take 4000 iu per day. I take 2000units the rest of the year.
It works, no colds, no flu. as to no Cancer, and other such big [roblems, none either.
It is not at a case of disproving anything. Before, Vitimin D was known th prevent rickets in children and some food was fortified.
The new knowledge does not eliminate or discredit, it adds and fortifies. The new research disproved nothing. You premise is false
Toxic accumulation usually occurs at about 30,000 IU daily over a two to three week period. Otherwise, a small number of people are sensitive to as little as a single dose of 3,000 IU, and elderly people and those with reduced liver or kidney function take longer to metabolize Vitamin D.
Likewise, it is important to be aware that unlike most other vitamins, Vitamin D is a hormone, so has somewhat different rules. Vitamin D from sunlight will to some extent be self limiting, as less is produced as the skin darkens. Likewise, taking supplements for an extended period can reduce natural production. Importantly, Vitamin D from sunlight can take a day or more to register as serum Vitamin D, so supplements are faster.
Vitamin D exists in relationships with other minerals and vitamins. The most important of these is Calcium, which in turn is interactive with levels of several other minerals, especially Sodium, Potassium, and Magnesium.
Vitamin D has half a dozen properties that work against pathogens. One of these is a breakdown product that is mildly acidic and erodes the protective coatings of viruses. Another effect is that it opens immunological pathways for cells that attack pathogens.
Another property not associated with immune system function is that Vitamin D acts as an ACE inhibitor, lowering blood pressure.
>>The body has no mechanism for excreting excess vitamin D, and vitamin D overexposure from excessive supplements can lead to toxic accumulation in adipose tissue, organ failure, kidney stones, deafness, etc.<<
True, but to get to the toxic level an adult would have to ingest amounts way above what is being recommended by those advocating added vitamin D3 supplementation.
>>Most people can get enough vitamin D to suit their needs from about 15 minutes of sunshine three times a week, even without any dietary supplements or drinking vitamin D supplemented milk.<<
This is not accurate. It’s exactly what many people do, and they are usually found to test less than 30ng/ml of D3.
>>But go ahead and get your medical advice from “Pajama Media” if you want.<<
Better yet, check out vitamindcouncil.org where Dr. Cannell summarizes recent research.
I take 5,0000 IU daily all winter (in Wisconsin) and will still supplement some in summer even though I’m outside a lot. Last summer I didn’t and my D3 dropped from 50ng/ml to 39 ng/ml over the summer months.
I recommend D3 testing in autumn (after summer sun) and in spring (before summer sun) for about 3 years running to get a feel for personal need for supplementation, but nearly everyone needs supplementation at some time of the year. Here’s a link to my website where I answer some of the questions that arise regarding vitamin D3 supplementation: http://ontrackreading.com/the-diet-piece/vitamin-d3-questions/
Thus it is not the dose level that would lead to toxic accumulation, it is how many years are you going to deposit that excess vitamin D before it accumulates to toxic levels.
If you have a website hawking Vitamin D I can see why you are promoting it.
There is no consensus or agreement on how much or what.
An early study found that 2000 iu/day prevented flu in hospital inmates where most of the others got flu.I followed the original study as reinforced by the good doctor Dr. Rosenfeld on Fox, 2000 iu regular, 4000 when flu is present in the population.
I bought 1,000 unit tabs at Walmart where they are cheap. The next time they were selling 2,000 unit tabs. Most recently they were selling 2,000 unit gelcaps. That means they are very much on to the trend and some higher effectiveness is perceived for the gelcap that is the Americans always seek to optimize to the max and I think that is case here.
If you do a little online research there is a ton of stuff in the last two years. There are many threads here on Free republic where I first learned about Vitamin D3.
““Anyone who accepts medical advice from an unqualified...”
...medical doctor (all who practice allopathic medicine) should ignore it and do their own research. Drs are generally nutritionally ignorant, and generally run the other way from natural approaches to health and healing.
While the “Mithritic Principle” does apply in SOME cases (where a small amount of a toxin can acclimate you to a bigger toxic load), generally the “homeopathic” mechanism is to dilute the toxin to nondetectable levels (i.e. 100% water) and this has never been shown to have any efficacy beyond the placebo effect.
When confronted that the “homeopathic principle” gives people water that ONCE was in contact with a toxin, they decided that some sort of mystical ‘molecular memory’ was in play.
Ludicrous.
These are Harvard and UC research docs saying the SAME THING.
Of course, you're free to argue against them too.
Every scientific advance has resulted in the falsification of the previous “scientific consensus” The whole notion of a “scientific consensus” is anti-science — that's why I've used scare quotes. All scientific knowledge is provisional — it is best described as “not yet disproved”.
I don't wish to hijack this thread — but, I think everyone knows where the most egregious abuse of the expression “scientific consensus” occurs these days. Anyone who tells you something is so, because of a “scientific consensus”; either doesn't know anything about science, or they're trying to mislead.
As a scientist, you’ve studied the more recent research in this area, particularly the research tending toward conclusions that differ from yours? Or do you simply classify all of that as loony?
http://www.vitamindcouncil.org/vitaminDToxicity.shtml
Perhaps you can answer Dr Vieth’s question by producing evidence that 10,000 units of vitamin D a day is toxic. Evidence, not ad hominem attacks or personal opinion.
“Vitamin D exists in relationships with other minerals and vitamins. The most important of these is Calcium...”
High levels of D3 (10,000 units a day or more, up to 50,000 units a day) should not be taken with any calcium supplementation. Reduced liver or kidney function results from the calcium supplementation, not from the D3. Generally no one needs calcium supplementation. Most of us need magnesium. Calcium from non-fortified or adulterated food sources is ok. For instance, raw milk is healthy.
I know a medical doctor (Norm Shealy, MD,PhD) who has been supplementing D3 at 50,000 units a day for nearly two years. He does get his D3 levels tested on a regular basis. He does not supplement calcium.
“Anyone who is a proponent of “homeopathic medicine”...
Where did you get the idea that I am a proponent of homeopathy? You will find no references to homeopathy in any of my posts on this thread or any other.
>>No, because there is no mechanism for ridding the body of excess, ANY amount over and above what is required MUST be stored in the body.
Thus it is not the dose level that would lead to toxic accumulation, it is how many years are you going to deposit that excess vitamin D before it accumulates to toxic levels.<<
While this is possible, it’s also possible that the body does in fact have a way of reducing the uptake of D3 once a person finally reaches a level that’s sufficient to fill all the body’s needs. In fact, there is some recent research suggesting this possibility, though I don’t have a reference. Nonetheless, I agree that you can’t take huge doses day after day without adverse effects.
>>If you have a website hawking Vitamin D I can see why you are promoting it.<<
You obviously didn’t read the original article, or you’d have known that the author was relying upon one of the premier vitamin D researchers as a source. Similarly, you didn’t read my website. If you did, you’d find that I am not “hawking” vitamin D3. I have no monetary interest in sales of D3 anywhere. The page was an effort to answer basic questions, such as D3 vs. D2, what test to order, etc., as you’d have found if you’d have actually taken the time to read it.
Perhaps you are ignorant of the fact that this phrase was coined by the originator of “homeopathic medicine” to differentiate it from his own quack ludicrous beliefs.

What I qualified as loony is the unsubstantiated claim that one can reduce their risk of all major diseases by 50-80% by taking a vitamin pill; or any pill for that matter, although I guess a cyanide pill would reduce your chance of suffering from any major disease by 100%! ;)
