Consumer Reports investigators found all fifteen of these ingredients in products available online or in stores such as Costco, BNC, Target, Vitamin Shoppe, Vitamin World, Walgreens, CVS, Walmart, and Whole Foods. In 2013, a report from the Government Accountability Office found that the FDA received 6,307 reports of health problems from dietary supplements between 2008 and 2011. Those reports included 1000 serious injuries or illnesses, hundreds of life-threatening conditions, and 92 deaths.
Manufacturers of dietary supplements do not have to prove to the FDA that their products are safe before they are sold to consumers. The FDA can take action if they can prove the supplements contain unapproved ingredients, or after these products have harmed people. Many recalls over the years have been issued for these reasons.
Here are the ingredients Consumer Reports advises consumers to avoid, along with the conditions they claim to help, and the potential risks. Always read labels of any product you buy, even if you have been using it for years. Manufacturers can change the ingredients in a product at any time with no notice.
