NCCAM Criticism from a Not-Quite-Opponent
The demographic of SBM readers are likely to remember the early Miller Lite beer television commercials where sports personalities debated as to whether the beverage “tastes great” or was “less filling.” In one classic version, New York Mets’ Marv Throneberry breaks the shouting match to level his decision: “I feel strongly both ways.” My colleagues at Science-Based Medicine have generally been opposed...
Vitamin B12 – The Energy Panacea?
Having spent many hours working in close proximity to a wall of vitamins, I’ve answered a lot of vitamin questions, and given a lot of recommendations. Before I can make a recommendation, I need to ask some questions of my own. My first is almost always, “Why do you want to take a vitamin?” The most common response I’m given is “insurance”...
Pediatrics & “CAM” II: just wrong
In November, the journal Pediatrics published an entire supplement devoted to Pediatric Use of Complementary and Alternative Medicine: Legal, Ethical and Clinical Issues in Decision-Making. The authors purport to have “examined current legal, ethical, and clinical issues that arise when considering CAM use for children and identified where gaps remain in law and policy.” (S150) Their aim is to “illustrate the relevance...
Antioxidants and Exercise: More Harm Than Good?
Multivitamin supplementation has been getting a rough ride in the literature, as evidence emerges that routine supplementation for most is, at best, unnecessary. Some individual vitamins are earning their own unattractive risk/benefit profiles: Products like folic acid, calcium, and beta-carotene all seem inadvisable for routine supplementation in the absence of deficiency or medical indication. Vitamin E, already on the watch list, looks...
Pediatrics & “CAM” I: the wrong solution
Oh no! Not again! The venerable medical journal Pediatrics devotes an entire supplement this month to Pediatric Use of Complementary and Alternative Medicine: Legal, Ethical, and Clinical Issues in Decision-Making. We sense from the very first sentence that we are in familiar territory: Rapid increases the use of complementary and alternative medicine (CAM) raise important legal, ethical, clinical, and policy issues. (S150)...
Collagen: An implausible supplement for joint pain
I’m one of those odd people that enjoys distance running. I end up spending a lot of time in the company of other runners. And when we’re not running, we’re usually griping about our running injuries. As the cohort that I run with ages, the injuries are getting more prevalent. Besides the acute conditions, the chronic problems are starting to appear. Our...
Premature Claims for Neurotrophic Factors
Scientific medicine is not easy. By this point we have largely picked the low hanging fruit, and continued improvements are mostly incremental and hard won. In order to get the most out of our limited research dollars, and optimize medical practice with the safest and most effective treatments, we need to use all available scientific evidence in the proper way. That is...
Weight Loss Customers Are Being Hoodia-Winked
I first wrote about Hoodia in my “SkepDoc” column in Skeptic magazine (Vol. 13, No. 1, 2007). The following is adapted from that column with an update from new research revealing that it doesn’t work and that it causes worrisome side effects. I first heard of Hoodia in 2006, when a radio ad informed me that it was the new miracle weight...
Milk Thistle and Mushroom Poisoning
If you’ve been fortunate to live in the parts of the US that were soggier than usually as of late – or unfortunate enough to have had flooding from hurricanes and tropical storms – then you’ve be noticing a tremendous burst of mushrooms. For mycologists – mushroom enthusiasts – there are two classic chestnuts: “There are old mushroom collectors and bold mushrooms...
Alpha Brain – What’s Wrong with the Supplement Industry
There is an endless stream of supplement products on the market that are of questionable value. They tend to follow a similar pattern: put an essentially random assortment of vitamins, minerals, perhaps herbs and nutritional elements into a pill and then make whatever pseudo-health claims you want. Usually the claim is implied in the name of the product itself – sleepwell, or...
