GNC’s Glucosamine Sulfate

In April 2020, a class-action lawsuit was filed against GNC for allegedly falsely marketing Glucosamine Sulfate. Specifically, plaintiffs claim that the ingredients list shows that the supplement contains d-glucosamine sulfate and sodium when, according to the complaint, testing shows the supplement actually contains glucosamine hydrochloride and sodium sulfate instead of glucosamine sulfate and sodium. (Amavizca et al v. GNC Holdings, Inc., Case No. 20-cv-3545, C.D. Cal.)
