Feds Seize Dietary Supplement from Leetsdale Warehouse, GNC Responds

GNC officials accuse the Food and Drug Administration of retaliation after federal attorneys moved to seize more than 1,500 cases of exercise enhancement products at the GNC warehouse in Leetsdale, according to the Post-Gazette.

"DMAA-containing products may continue to be sold and/or distributed everywhere in the U.S. except this one GNC distribution facility ... Given this situation, it is hard to view this action as anything other than a biased agency action against GNC in retaliation for GNC's stance on DMAA," the GNC statement said.

Last week, federal officials filed action seeking the destruction of Jack3d and OxyELITE Pro at the GNC warehouse because the products contain DMAA.

The FDA says DMAA "can elevate blood pressure and could lead to cardiovascular problems, including heart attack, shortness of breath and tightening of the chest."

GNC says DMAA is safe and will keep the cases in the warehouse, but will continue to sell its remaining inventory of the products in stores, according to the newspaper.
