MET-Rx Big 100 Colossal Bar

The Big 100 Colossal Bar is a flagship product of MET-Rx, a brand that pioneered the meal replacement category in the sports nutrition industry. Originally developed in the late 1980s by anesthesiologist Dr. Scott Connelly, the brand focused on a proprietary protein blend called Metamyosyn, designed to support muscle mass and metabolic health.

Today, MET-Rx is part of the 1440 Foods portfolio, a sports nutrition company formed following the acquisition of certain brands from The Bountiful Company (formerly NBTY). The Big 100 bars are primarily manufactured in the United States, catering to athletes and fitness enthusiasts who require high-calorie, high-protein meal options. The brand has transitioned through several major corporate owners, including Rexall Sundown and NBTY, before becoming a core component of the 1440 Foods lineup, which is backed by private equity investment to expand its reach in the health and wellness market.
