supplementsThe $26.7 billion supplemental medicine industry received a much-needed kick in the ass.

Results of a new investigation by Consumer Reports, released yesterday, warn consumers to avoid 12 supplement ingredients that have been linked to cancer, coma, heart problems, kidney damage, liver damage, and death.

Consumer Reports worked with the Natural Medicines Comprehensive Database, an independent research group that evaluates the safety and effectiveness of nutritional supplements, to develop this list.

Consumers might be attracted to dietary supplements because they’re “all natural” and don’t contain the synthetic chemicals found in prescription drugs. But they might be getting fooled. Hidden drugs and steroids have been detected in more than 170 supplements since 2008. Hazardous ingredients have been known to turn up in dietary supplements marketed for weight loss, bodybuilding, and sexual enhancement.

More than half of the adult population in the U.S. take supplements for a variety of reasons — to stay healthy, lose weight, gain an edge in sports, or to improve their performance in the bedroom. What many consumers don’t realize is that the supplement manufacturers routinely, and legally, sell their products without first having to demonstrate that they are safe and effective.

Of the more than 54,000 dietary supplement products in the Natural Medicines Comprehensive Database, only about a third have some level of safety and effectiveness that is supported by scientific evidence, according to a review by NMCD experts. And close to 12 percent have been linked to safety concerns or problems with product quality.

Because of inadequate quality control and inspection, supplements contaminated with heavy metals, pesticides, or prescription drugs have been sold to unsuspecting consumers.

And FDA rules covering manufacturing quality don’t apply to the companies that supply herbs, vitamins, and other raw ingredients.

The following supplement ingredients are among those linked by clinical research or case reports to serious side effects.  They should be avoided at all costs. (source:  http://www.consumerreports.org/health/natural-health/dietary-supplements/supplement-side-effects/index.htm)

    This is why I use BioVeda products – http://www.biovedawellness.com . I can trust the ingredients rather than purchasing something coming from China. They are straightforward about what is in their products. I like that they offer vitamin D3 which is absorbed better by the body than D2. I think they just have it together more than some of these companies trying to make a quick buck.

    That may be the case, but be careful: BioVeda is listed on QuackWatch as a dubious institute:

    Yes, indeed! People should know about joint pain . I'm searching for natural joint pain supplement and found your page.. you've got an interesting topic.

    There are a lot of supplements in town and we are not really sure if which one's safe or which one's will harm you and your family. My neighbor once taken a nutrition supplement and that almost ruined her life. Good thing he was taken immediately to a hospital in our town in Ottawa. Personal injury lawyer helped him also to sue the company of the said supplement.

    We must all be careful when it comes to buying supplements for our body.
