GNC’s TriFlex Supplements
July 2013: A class-action lawsuit was filed against GNC for allegedly deceptively marketing its TriFlex supplements. The plaintiffs allege that GNC markets TriFlex, which consists primarily of glucosamine hydrochloride and chondroitin sulfate, as a supplement that will help promote mobility and flexibility, improve joint comfort, and cushion joints, without adequate scientific support for those claims. (Distefano-Presutti et al. v. GNC Corp., Case No. 13-cv-01100, W.D. Penn.)
