Consumer Reports has singled out 12 common ingredients in dietary supplements that could be more dangerous than previously thought.
According to researcher Nancy Metcalf, these "dirty dozen" ingredients have been linked to range of side effects including cancer, coma and heart problems. Some have even been connected with deaths.
"The dozen we call out in this report are by no means the only dangerous ingredients," Metcalf, a senior program editor at Consumer Reports, told WebMD. "They are the ones we chose to highlight."
For the study Metcalf and other researchers reviewed data from a list of 1,100 supplement ingredients from the Natural Medicines Comprehensive Database. Ultimately, they narrowed the list down to 12 that had been recently connected with dangerous side effects.
Metcalf adds that about "half the adult population takes some supplement," and notes that "you need to be extremely careful about buying nutritional supplements, because there are several different ways they can be harmful."
