The attorney general’s warning involved GNC, Target, Wal-Mart and Walgreens, and alleged that some herbal supplements may not contain the active ingredients they are supposed to contain. For example, supplements called St. John's Wort were found to contain no St. John’s Wort. Furthermore, the attorney general alleged that some herbal supplements may contain fillers and other ingredients not listed on the labels, putting consumers at risk of an allergic reaction or other adverse event.
The retailers involved in the attorney general’s investigation were ordered to pull certain herbal supplements from their shelves based on DNA testing that questioned the validity of the supplements’ labels. Following that order, New York Attorney General Eric Schneiderman then sent letters to manufacturers ordering the manufacturers to send detailed information regarding ingredients of herbal supplements sold in New York state.
Among the manufacturers ordered to send information, according to CBS News (2/24/15), were Pharmavite LLC, Nature’s Way Products Inc., NBTV Inc., and Nutraceutical.
There are some concerns, however, about Schneiderman’s DNA testing of the herbal supplements. Critics say the DNA testing would not necessarily show the DNA of extracts used in the supplements, making further chemical analysis necessary. Information sent by the manufacturers could provide more information about what ingredients specifically are in each herbal supplement and what quality control measures the supplement makers have taken.
