Common questions
Frequently asked questions about GNC.
What types of products does GNC sell?
GNC sells nutritional supplements including protein powders, pre-workout formulas, vitamins and minerals, weight management products, herbal supplements, sports nutrition bars and drinks, and general health and wellness products. GNC carries both its own house brands and third-party supplement brands.
Are GNC supplements tested for safety?
Dietary supplements in the U.S. are regulated by the FDA as food rather than drugs, meaning manufacturers are not required to prove efficacy before selling. GNC tests products for quality and has its own quality assurance program, but individual product safety should be evaluated in consultation with a healthcare provider. Not all supplements are appropriate for everyone.
Does GNC offer a loyalty program?
GNC offers a free membership program that provides access to member pricing and discounts. GNC also offers a paid membership tier with additional benefits. Details and current program structure are listed at gnc.com.
