About us

Protein Headquarters is Chicagoland's Premier Discount Vitamin & Supplement Retailer. (Previously named Armor Nutrition)

Protein Headquarters is a family owned and operated company that was established in 2013. All our staff members are highly knowledgeable on supplements, nutrition, and fitness.  We are located in Tinley Park, IL.

With the supplement industry expanding at a crazy pace, there are new brands and ingredients popping up every day. We do not expect our customers to keep up with this ever-changing market. We realize your time is valuable, so we do the leg work so you don’t have to. You will notice our website and stores are not filled with hundreds of different brands like most other websites. We only provide you with the best supplements that we feel are deserving of your money and worthy enough to put in your body.
