Investigators find heavy metals in herbal supplements

A congressional investigation of dietary herbal supplements has found trace amounts of lead, mercury and other heavy metals in nearly all products tested.

That's according to a report by The New York Times that also says that investigation found a myriad of illegal health claims made by supplement manufacturers.

The levels of heavy metal did not exceed established limits, but investigators reportedly also discovered troubling and possibly unacceptable levels of pesticide residue in 16 of 40 supplements.

The Council for Responsible Nutrition that represents the supplement industry says it is not surprising that herbal supplements contained trace amounts of heavy metals because they are routinely found in soil and plants. It adds this should not be of concern to consumers.
