Should I Take a Multivitamin?
I’ll start with a confession. I used to do something irrational. I used to take a daily multivitamin, not because I thought there was good scientific evidence to support the practice, but for psychotherapy. I tried to eat a healthy diet and worried about it. By taking a pill, I could stop worrying. Then I found out that higher intake of vitamin...
Cavalcade of Quackery: A Pantomine Horse
Last week I received the news release below that Steve Zeitzew, an orthopedic surgeon at VA Hospital Los Angeles and UCLA, sent to the Healthfraud list. It was sent to me by our colleague Liz Woeckner, President of the nonprofit research protection advocacy organization Citizens for Responsible Care in Research (CIRCARE) http://www.circare.org/ Ms. Woeckner sent it on with a cryptic comment, wondering...

Another State Promotes the Pseudoscientific Cult that is “Naturopathic Medicine.” Part 4
The “Science” and Ethics of “Natural Medicines” (and Nutrition) cont. This is the continuation of a discussion concerning the explicit claim of “naturopathic physicians”* to being experts in the use of “natural medicines,” defined as “medicines of mineral, animal and botanical origin.” Last week’s post established that the cult has chosen to profit from the “retail selling of medications,” as evidenced by the relevant...
Another State Promotes the Pseudoscientific Cult that is “Naturopathic Medicine.” Part 3
The “Science” and Ethics of “Natural Medicines” This and the next entry in the current “Naturopathic Medicine” series* deal with the cult’s claim of expertise in “natural medicines” or “natural remedies.” These include herbs (“botanicals”), glandular extracts, vitamins, and minerals. A large fraction of the Textbook of Natural Medicine (TNM), “the most thoroughly researched and carefully referenced text on natural medicine,” is devoted...
Canada Bill C-51 – Regulating Natural Health Products
In Canada a new bill has been proposed, Bill C-51, that would make changes to the Food and Drug Act – the body of laws by which the Canadian federal government regulates food and health products in Canada. This is the equivalent of the Food and Drug Administration (FDA) in the US. It seems that Canada, like the US, is struggling to...
Airborne Settles Case On False Advertising
The story of Airborne – a popular supplement marketed as an “herbal health formula that boosts your immune system to help your body combat germs” – is representative of what is wrong with the supplement industry and how it is regulated in the US. Recently the company that sells Airborne – Airborne Health, Inc – agreed to pay $23.3 million to refund...
Science-Based Nutrition
Nutrition is embedded in mainstream medical teaching and practice, despite efforts to convince patients to the contrary (usually in an effort to sell them something).
Glucosamine Update: A New Study and a New Product
When I recently wrote about glucosamine, I discussed the evidence up through the New England Journal of Medicine study of 2006, which I thought was a pretty definitive study showing that neither glucosamine, chondroitin or a combination of the two was more effective than placebo. Subsequent studies have continued to fuel the controversy. One 2007 study showed that glucosamine sulfate was better than placebo for knee osteoarthritis. Another 2007 study showed...
Super Fruit Juices – The New Snake Oil
The core principle of science-based medicine is that health care decisions should be based upon our best current scientific evidence and understanding. When applied to the regulation of health products this means that health claims should first be required to meet some reasonable threshold of scientific evidence before they are allowed. Admittedly this is not a purely scientific question but the application...
Antioxidant Hype and Reality
A new study by lead author Shelly Gray and published in the latest issue of the Journal for the American Geriatric Society, found no effect from taking Vitamin C or E, either alone or in combination, on the risk of dementia or Alzheimer’s disease after 5.5 years. Vitamins C and E were chosen because they both have significant antioxidant activity, and so...
