15 supplement ingredients to always avoid

By: WFTS Webteam

Consumer Reports, with the help of an expert panel of independent doctors and dietary-supplement researchers, identified 15 supplement ingredients that are potentially harmful.

The risks of the identified supplement ingredients include organ damage, cancer, and cardiac arrest. The severity of these threats often depends on such factors as pre-existing medical conditions as well as the quantity of the ingredient taken and the length of time a person has been exposed to the substance.

Many of the ingredients on the list also have the potential to interact with prescription and over-the-counter medications, such as cholesterol-lowering statins and blood-thinning drugs like aspirin and warfarin (Coumadin and generic), according to Consumer Reports.
