New Recommendations for Calcium and Vitamin D Intake
A Walmart ad in my local newspaper trumpets “75% of all Americans don’t get enough Vitamin D” and offers to sell me Maximum Strength Vitamin D3, 5000 IU capsules to “promote bone, colon and breast health.” Meanwhile, the Institute of Medicine (IOM) tells me that “the majority of Americans and Canadians are receiving adequate amounts of … vitamin D” and that no...
Vitamin E and Stroke
One of the recurrent themes of science-based medicine is that any medical intervention that can plausibly cause physiological benefit can also plausibly cause physiological harm. There is no such thing as “it can’t hurt.” Sometimes the risk may be minuscule – but we should never assume that it is zero. Being “natural” or “holistic” or being blessed with some other alleged marketable...
Speaking Skeptically About Vitamins
The scientific understanding of vitamins has evolved over time, from the identification of frank deficiencies, to exploring the value of supplements to prevent chronic diseases. Among health professionals, taking a multivitamin “for insurance” has long been considered to be a reasonable strategy. But as more robust evidence has emerged about the benefits and possible harms of vitamins, even that advice is facing...
Another Negative Study of Vitamins
Perhaps one of the most common questions I receive from those who wish to utilize science-based medicine for their own health is what I think about vitamins. Even among hard-nosed skeptics, this question is often perplexing. On the one hand, vitamins themselves were discovered by medical and biological science, they play a vital role (by definition) in the healthy functioning of our...
Vitamin Cocktail with a Meme Twist (Supplement my gimlet with a dash of dissonance)
A trail of recent reports is trying to tell us something. But are we listening, and are “they” listening? If so, does it mean the same to “them” as it does to us? The report trail is telling us that multiple vitamins fail as preventatives against cardiovascular disease, cancer, or even for anything other than for dietary vitamin deficiency. And that is...
Vitamin C strikes (out) again
A new research paper on vitamin C and cancer came out recently, but didn't get much attention in the press. Why not? Because this one found vitamin C actually made things worse.
High dose vitamin C and cancer: Has Linus Pauling been vindicated?
Treating cancer with high-doses of vitamin C is a zombie idea that began with Linus Pauling, and has failed to die ever since. But has new research vindicated this idea? No. No in any meaningful way. This work is the very definition of a long run for a short slide.
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...
We finally learn from TACT2 what we should have known two decades ago: Chelation therapy doesn’t work for heart disease
At SBM, we've long argued that chelation therapy for heart disease is quackery. An abstract presented recently finally confirmed that. Why did it take so long?
