Drinkable Sunscreen Snakeoil
In May, prompted by an uncritical article in the Daily Mail, the internet was buzzing about a company that was offering drinkable sunscreen. This is one of those game-changer health products that immediately garners a great deal of attention. At first the claim seems extraordinary, but it is not impossible. It is theoretically possible to drink a substance that becomes deposited in...
Medical marijuana as the new herbalism, part 1: Science versus the politics of weed in New York and beyond
Medical marijuana. It's promoted as a seeming panacea that can cure whatever ails you. While there are potentially useful medicinal compounds in marijuana, in general the medical marijuana movement vastly oversells the promise. The truth is far more prosaic and nuanced.
John Oliver skewers Dr. Oz for his hawking of diet supplements
As regular readers of this blog know, Dr. Mehmet Oz had a very, very bad day last week, in which he received a major tongue lashing from Senator Claire McCaskill (D-MO) for the scientifically unsupported and irresponsible hyperbole he dishes out day after day on his syndicated daytime television show. Personally, I was tempted to pile on myself, but had to content...
Dr. Oz and the Terrible, Horrible, No Good, Very Bad Day
Dr. Mehmet Oz is one of the most well-known, and possibly the most influential medical doctor in America. The Dr. Oz Show is broadcast in 118 countries and reaches over 3 million viewers in the USA alone. When Oz profiles a product or supplement on his show, sales explode – it’s called “The Dr. Oz Effect”. Regrettably, Oz routinely and consistently gives...
Turmeric: Tasty in Curry, Questionable as Medicine
A correspondent asked me to look into the science behind the health claims for turmeric. He had encountered medical professionals “trying to pass turmeric as some sort of magical herb to cure us from the ‘post-industrial chemical apocalypse.’” It is recommended by the usual promoters of CAM: Oz, Weil, Mercola, and the Health Ranger (who conveniently sells his own superior product, Turmeric...
Macular Degeneration and AREDS 2 Supplements
Four years ago I wrote about the premature marketing of a diet supplement for macular degeneration before the results of a trial to test it were available. Now that we know the results of that trial, a follow-up post is in order. Age-related macular degeneration (AMD) is a leading cause of blindness. The incidence increases with age; it affects 10% of people...
VacciShield: Pixie dust for an imaginary threat
I know by now I shouldn’t be, but I am still amazed by how readily so many people buy into the seemingly endless array of bogus sCAM nostrums. Many are marketed and hawked for the treatment or prevention of diseases that are poorly managed by science-based medicine. There are countless examples of dietary supplements that are purported to effectively treat back and...
Don’t supplement users deserve consumer protection, too?
The Canadian Parliament, hypothetically protecting consumers since Confederation. One of the most pervasive yet appealing health myths is the idea that natural equals safe. It’s a statement that’s repeated constantly by manufacturers of supplements and “natural” health products. It’s been the primary argument used, with considerable success, to give these products completely different regulatory structures than exist for drug products. Weaker regulation...
Forskolin: Here We Go Again
My BMI is 21, but my e-mail and Facebook accounts must think I’m fat. I am constantly bombarded with messages about miracle weight loss solutions, and most of them are diet supplements featured on the Dr. Oz show. Back in December I wrote an article about Garcinia cambogia, Dr. Oz’s “newest, fastest fat buster.” I made this prediction: “I confidently expect another...
We’re a drug-taking, supplement-taking nation. So how do we do so safely?
Do you take a vitamin or dietary supplement? It’s increasingly likely that you do, as over half of all American adults took some sort of supplement over the past 30 days. Now there’s evidence to suggest that about one-third of all Americans are taking supplements and prescription drug at the same time, which is renewing questions about risks and benefits. The same...
