GBL marketers respond to FDA

Four supplement companies sent Jan. 27 FDA warning letters agree to cease manufacturing and distributing gamma-butyrolactone-containing products, but only three agree to recall the products. The letters were sent to Alpha Earth, Miracle Marketing Distributors, Advanced Athletic Nutrition and RenewTrient Research ("The Tan Sheet" Feb. 1, p. 3). In a Jan. 21 "Talk Paper," FDA had cautioned it would take action against any marketer that did not voluntarily recall its GBL-containing products ("The Tan Sheet" Jan. 25, p. 6). FDA would not disclose which company refused to recall the product; RenewTrient, however, says in an answering machine message it is "opposing" Florida and FDA's "judgement" that RenewTrient is not a nutritional supplement, asking others to join its "legal conflict"
