Contaminated supplements – spiked with potentially dangerous ingredients

The supplement industry is huge and unregulated. Americans spend more than $30 billion annually on them, yet contaminated supplements are part of the industry’s method to make their mostly useless products appear to have some clinical effect. There is growing evidence that these contaminated supplements contain unlabeled ingredients that are found in regulated pharmaceuticals – all …

Supplements for cardiovascular diseases – more evidence that they don’t work

I have been skeptical of supplements for a long time – not because I have some predisposition against them. My skepticism results from the relative lack of any robust evidence that supplements have any positive effect on human health other than in unique situations of chronic diseases or malnutrition. In fact, most of the high-quality …

Omega-3 supplements have little effect on cardiovascular disease and mortality

I have been skeptical of supplements for a long period of time. Supplements are generally of low quality, they don’t prevent or cure cancer, they don’t prevent colds, they can’t boost the immune system, and they don’t prevent heart disease. Now there is a powerful review of omega-3 supplements that shows that it has little …

Dietary supplements make costly urine – not helpful for CVD

I have never been a fan of dietary supplements pushed by Big Supplement, the less regulated, less evidence-based, more pseudoscientific mirror image of Big Pharma. Recently, a meta-review published in a respected journal examined whether there were any causal links between various dietary supplements and cardiovascular disease (CVD). They only found one, folic acid, that …

Vitamin supplements do not lower risk of cancer and heart disease

Vitamin and mineral supplements are important to maintaining proper levels of these nutrients when they aren’t obtained from the diet. Generally, if a human consumes a diet of broad based foods, there is little need for supplementation, unless they are afflicted with a chronic medical disorder which requires additional nutrients. Vitamins and minerals do not …

Vitamin D supplements–improves bone health or a waste of money?

Lots of people take vitamin D supplements to keep their bones strong as they age, advice that is pushed by legitimate organizations, like the National Osteoporosis Foundation. But does vitamin D actually do anything, or are their effects some kind of myth?  A group of researchers in New Zealand examined previous clinical trials involving vitamin …

“Natural” supplements are filled with dangerous junk

When Big Pharma develops a new prescription medication, the regulatory authorities, such as the US FDA, set regulatory guidelines for not only the claims made by the company but also for the manufacturing standards. Every ingredient used to manufacture a pill or injectable must be listed in the package insert and must be tested during …

Supplements to treat the common cold–myth vs science

It’s getting colder outside, and if you go into any pharmacy, grocery store, chemist, or superstore, you will find literally a dozen or more homeopathic, herbal, or other unproven lotions and potions to prevent or treat the common cold, or rhinovirus. These supplements are a significant part of the annual US$108 billion dollar supplement/nutraceutical industry.  These …

Herbal supplements–unproven, unregulated, unsafe

One of the more ironic memes on the internet is how pharmaceutical companies make so much money (and they do), with the false conclusion that somehow all that money means that they’re not really interested in providing drugs that are safe and efficacious. Then, those same memes will claim that “natural supplements” are healthier and …
