Grenade Protein Bars, originally launched as the iconic Carb Killa Bars, are about to become unmissable in the United States.
Despite being hailed as one of the UK’s favorite functional snacks, the explosive treats haven’t quite replicated that success across the pond.
The likes of Amazon and Costco have stocked the top-rated bars in recent times, yet availability has remained relatively patchy.
That is about to change, however, as industry veteran and distribution heavyweight Nutralabz has agreed a deal to drive sales and expand reach throughout the country.
“Pulling the Pin” on Grenade Protein Bars
“Grenade has landed,” it wrote in a post on LinkedIn.
“Nutralabz is excited and proud to announce our partnership with Grenade as the Official US supplier!
“We’re about to PULL THE PIN on some iconic activations, new moments and bring the top selling protein bar brand in the UK to customers across the United States!”

Grenade previewed the announcement by making its first-ever appearance at the Arnold Sports Festival in Columbus, Ohio, over the weekend, bringing several of its signature flavors along for fans to try.
That moment marked the brand’s official return and relaunch in the States — and a statement of intent for its renewed push to replicate its UK dominance in the US.
Powered by Nutralabz, expect to see Grenade Protein Bars start cropping up in gyms, big-box retailers, gas stations, and sports nutrition stockists across the country.
Barebells currently sits on the throne as America’s protein bar of choice — though Grenade’s latest charge could put that reign under serious threat.
