In November 2016, a class-action lawsuit
was filed against GNC for allegedly deceptively marketing L-Glutamine Pro Perforamnce® dietary supplements – including L-Glutamine Powder 5000, L-Glutamine 1500, RapidDrive Glutamine 2500 Power Chew,and RapidDrive Glutamine 5000 – as having “Anti-Catabolic Effects,” “Support[ing] Muscle Function,” and “Support[ing] Faster Recovery After Workouts” when, in reality, such claims are false and scientific evidence has found that glutamine supplements do not provide the same benefits as glutamine found naturally in the body. (Wagner et al v. General Nutrition Corp.
, Case No. 16-cv-10961, N. D. IL.)
