falsehoods in Megavitamin therapy articleI have detailed my arguments in the history section. "Quackwatch" is not reliable: http://longevitylibrary.com/article/243.pdf Of course people have not viewed that article. What it shows is that Barett frequently engages in character assasinations, does not have an authoritative background (he was a bit of a failure until he got into his recent bit of hucksterism), that there are a plethora of peer reviewed studies on Pubmed supporting CAM, that there are authoritative sources completely refuting Barett on many of his major points, and that he has shamelessly libeled his opponents, as exposed in court cases. It uses facsimilies of primary documents from a recent court case to prove it's point. For the various vitamin citations, I have given mainstream medical publications that refute the other arguments. The citation on Schizophrenia shows that vitamins do indeed help prevent mental illness - hence refuting the fundamental objections to orthomolecular medicine. For some reason, the "doctor yourself" website has been deemed "unreliable". Hoaxers like Stephen Barett are given ample space. Nevertheless, the doctor yourself website has an excellent overview of this insanity. I will post just the beginning of the article: http://www.doctoryourself.com/safety.html By golly, Lincoln was right. You really can fool some of the people all of the time. When the topic is vitamins, some of the most easily fooled are news broadcasters and newspaper reporters. IF YOU HAVE RECENTLY HEARD THAT VITAMINS ARE HARMFUL, you may want to read this page, or at least as much of it as you need to get your perspective back.
How to Make People Believe Any Anti-Vitamin Scare It Just Takes Lots of Pharmaceutical Industry Cash by Andrew W. Saul, Orthomolecular Medicine News Service, October 20, 2011 Recent much trumpeted anti-vitamin news is the product of pharmaceutical company payouts. No, this is not one of "those" conspiracy theories. Here's how it's done: 1) Cash to study authors. Many of the authors of a recent negative vitamin E paper (1) have received substantial income from the pharmaceutical industry. The names are available in the last page of the paper (1556) in the "Conflict of Interest" section. You will not see them in the brief summary at the JAMA website. A number of the study authors have received money from pharmaceutical companies, including Merck, Pfizer, Sanofi-Aventis, AstraZeneca, Abbott, GlaxoSmithKline, Janssen, Amgen, Firmagon, and Novartis. 2) Advertising revenue. Many popular magazines and almost all major medical journals receive income from the pharmaceutical industry. The only question is, how much? Pick up a copy of the publication and count the pharmaceutical ads. The more space sold, the more revenue for the publication. If you try to find their advertisement revenue, you'll see that they don't disclose it. So, just count the Pharma ads. Look in them all: Readers Digest http://orthomolecular.org/resources/omns/v06n11.shtml , JAMA, Newsweek, Time, AARP Today, NEJM, Archives of Pediatrics. Even Prevention magazine. Practically any major periodical. 3) Rigged trials. Yes, it is true and yes it is provable. In a recent editorial, we explained how trials of new drugs are often rigged at http://orthomolecular.org/resources/omns/v04n20.shtml . Studies of the health benefits of vitamins and essential nutrients also appear to be rigged. This can be easily done by using low doses to guarantee a negative result, and by biasing the interpretation to show a statistical increase in risk. 4) Bias in what is published, or rejected for publication. The largest and most popular medical journals receive very large income from pharmaceutical advertising. Peer-reviewed research indicates that this influences what they print, and even what study authors conclude from their data. http://orthomolecular.org/resources/omns/v05n02.shtml . 5) Censorship of what is indexed and available to doctors and the public. Public tax money pays for censorship in the largest public medical library on the planet: the US National Library of Medicine (MEDLINE/PubMed). http://orthomolecular.org/resources/omns/v06n03.shtml. See also: http://orthomolecular.org/resources/omns/v06n05.shtml. Don't Believe It? How well were these pro-vitamin, anti-drug studies covered in the mass media? •A Harvard study showed a 27% reduction in AIDS deaths among patients given vitamin supplements. (2) •There have been no deaths from vitamins in 27 years. http://orthomolecular.org/resources/omns/v07n05.shtml •Antibiotics cause 700,000 emergency room visits per year, just in the US. (3) •Modern drug-and-cut medicine is at least the third leading cause of death in the USA. Some estimates place medicine as the number one cause of death. (4) •Over 1.5 million Americans are injured every year by drug errors in hospitals, doctors' offices, and nursing homes. If in a hospital, a patient can expect at least one medication error every single day. (5) •More than 100,000 patients die every year, just in the US, from drugs properly prescribed and taken as directed. (6) Double Standard Countless comedians have made fun of the incompetent physician who, when called late at night during a life- threatening disease crisis, says, "take two aspirin and call me in the morning." It's no longer funny. One of the largest pharmaceutical conglomerates in the world ran prime- time national television commercials that declared: "Bayer aspirin may actually help stop you from dying if you take it during a heart attack." The company also promotes such use of its product on the Internet. http://www.wonderdrug.com/ , formerly http://www.bayeraspirin.com/news/heart_attack.htm Daily Aspirin Use Linked With Pancreatic Cancer Here's something you may have not seen. Research has shown that women who take just one aspirin a day, "which millions do to prevent heart attack and stroke as well as to treat headaches - may raise their risk of getting deadly pancreatic cancer. . . . Pancreatic cancer affects only 31,000 Americans a year, but it kills virtually all its victims within three years. The study of 88,000 nurses found that those who took two or more aspirins a week for 20 years or more had a 58 percent higher risk of pancreatic cancer." (7) Women who took two or more aspirin tablets per day had an alarming 86 percent greater risk of pancreatic cancer. Study author Dr. Eva Schernhammer of Harvard Medical School was quoted as saying: "Apart from smoking, this is one of the few risk factors that have been identified for pancreatic cancer. Initially we expected that aspirin would protect against pancreatic cancer." How about that. Say: What if there was one, just one case of pancreatic cancer caused by a vitamin? What do you think the press would have said about that? The fact is, vitamins are known to be effective and safe. They are essential nutrients, and when taken at the proper doses over a lifetime, are capable of preventing a wide variety of diseases. Because drug companies can't make big profits developing essential nutrients, they have a vested interest in agitating for the use of drugs and disparaging the use of nutritional supplements.

The American Association of Poison Control Centers, which maintains the USA’s national database from 61 poison control centers, indicates that even including intentional and accidental misuse, the number of vitamin fatalities is less than one death per year. http://www.doctoryourself.com/vitsafety.html And, it turns out, that there is NO documented evidence that any one of those alleged "deaths" was due to a vitamin. No evidence whatsoever. http://www.doctoryourself.com/vitsafety.html Drugs, however, are an entirely different matter: “Harmful reactions to some of the most widely used medicines — from insulin to a common antibiotic — sent more than 700,000 Americans to emergency rooms each year, landmark government research shows.” (Associated Press, Oct 17, 2006) http://www.msnbc.msn.com/id/15305033/ VITAMIN BASHING IS NONSENSE The news media can be absolutely relied on to trumpet any allegation that vitamins are harmful. Vitamin E has been accused of actually causing deaths. Even multivitamins have been accused of causing deaths. Baloney. What Kind of Medical Study Would Have Grandma Believe that Her Daily Multivitamin is Dangerous? Orthomolecular Medicine News Service, October 12, 2011 by Robert G. Smith, PhD (OMNS, Oct 12, 2011) A newly released study suggests that multivitamin and nutrient supplements can increase the mortality rate in older women . However, there are several concerns about the study's methods and significance. • The study was observational, in which participants filled out a survey about their eating habits and their use of supplements. It reports only a small increase in overall mortality (1%) from those taking multivitamins. This is a small effect, not much larger than would be expected by chance. Generalizing from such a small effect is not scientific. •The study actually reported that taking supplements of B-complex, vitamins C, D, E, and calcium and magnesium were associated with a lower risk of mortality. But this was not emphasized in the abstract, leading the non-specialist to think that all supplements were associated with mortality. The report did not determine the amounts of vitamin and nutrient supplements taken, nor whether they were artificial or natural. Further, most of the association with mortality came from the use of iron and copper supplements, which are known to be potentially inflammatory and toxic when taken by older people, because they tend to accumulate in the body . The risk from taking iron supplements should not be generalized to imply that all vitamin and nutrient supplements are harmful. •The study lacks scientific plausibility for several reasons. It tabulated results from surveys of 38,000 older women, based on their recall of what they ate over an 18-year period. But they were only surveyed 3 times during that period, relying only on their memory of what foods and supplements they took. This factor alone causes the study to be unreliable. • Some of these women smoked (~15%) or had previously (~35%), some drank alcohol (~45%), some had high blood pressure (~40%), and many of them developed heart disease and/or cancer. Some preexisting medical conditions were taken into account by adjusting the risk factors, but this caused the study to contradict what we already know about efficacy of supplements. For example, the study reports an increase in mortality from taking vitamin D, when adjusted for several health-relevant factors. However, vitamin D has recently been clearly shown to be helpful in preventing heart disease and many types of cancer , which are major causes of death. Furthermore, supplement users were twice as likely to be on hormone replacement therapy, which is a more plausible explanation for increased mortality than taking supplements. •The effect of doctor recommendations was not taken into account. By their own repeated admissions, medical doctors and hospital nutritionists are more likely to recommend a daily multivitamin, and only a multivitamin, for their sicker patients. The study did not take this into account. All it did was tabulate deaths and attempt to correct the numbers for some prior health conditions. The numbers reported do not reflect other factors such as developing disease, side effects of pharmaceutical prescriptions, or other possible causes for the mortality. The study only reports statistical correlations, and gives no plausible cause for a claimed increase in mortality from multivitamin supplements. •The effect of education was not taken into account. When a doctor gives advice about illnesses, well-educated people will often respond by trying to be proactive. Some will take drugs prescribed by the doctor, and some will try to eat a better diet, including supplements of vitamins and nutrients. This is suggested by the study itself: the supplement users in the survey had more education than those who did not take supplements. It seems likely, therefore, the participants who got sick were more likely to have taken supplements. Because those who got sick are also more likely to die, it stands to reason that they would also be more likely to have taken supplements. This effect is purely statistical; it does not represent an increase in risk that taking supplements of vitamins and essential nutrients will cause disease or death. This type of statistical correlation is very common in observational health studies and those who are health-conscious should not be confounded by it. •The known safety of vitamin and nutrient supplements when taken at appropriate doses was not taken into account. The participants most likely took a simple multivitamin tablet, which contains low doses. Much higher doses are also safe , implying that the low doses in common multivitamin tablets are very safe. Further, because each individual requires different amounts of vitamins and nutrients, some people must take much higher doses for best health . Summary: In an observational study of older women in good health, it was said that those who died were more likely to have taken multivitamin and nutrient supplements than those who did not. The effect was small, and does not indicate any reason for disease or death. Instead, the study's methods suggest that people who have serious health conditions take vitamin and mineral supplements because they know that supplements can help. Indeed, the study showed a benefit from taking B-complex, C, D, and E vitamins, and calcium and magnesium. Therefore, if those wanting better health would take appropriate doses of supplements regularly, they would likely continue to achieve better health and longer life. (Robert G.
