GNC Reaches Accord With New York State on Herbal Supplements

GNC Holdings Inc. reached an agreement with the New York attorney general on its Herbal Plus products, pledging to more stringently test its supplements and follow U.S. Food and Drug Administration manufacturing recommendations. In response to state inquiries, GNC has conducted "rigorous tests" to show that its products are safe and properly labeled, according to a statement Monday. GNC also will begin performing DNA barcoding on products — a method of confirming that supplements have the right ingredients — and add signage to help consumers figure out what they're buying.
