Herbal supplements are a multi-billion dollar industry, but do consumers really know what they’e ingesting? A new study shows that supplement pills may actually contain a high amount of filler including wheat and rice, the wrong herb entirely, and sometimes ingredients that are downright dangerous.
Canadian researchers selected popular medical herbs and then purchased 44 bottles of varying brands from 12 local stores. The products were tested by using DNA bar-coding. Their findings concluded that many bottles were mislabeled or diluted. A staggering one-third of the plants advertised on the bottle had been replaced with another plant entirely. Customers were not getting what they paid for, and they were often receiving products with ingredients that could have annoying and potentially lethal side effects.
We reached out to our resident registered dietitian, Mary Hartley, for her thoughts on the study. “If one-third of the supplements showed outright substitution, then this is a huge, huge supplement industry problem,” she said. “Not only are the supplements ineffective, but they may contain harmful ingredients.”
