Each one delivers 20 grams of high-quality protein, zero sugar, and five essential vitamins and minerals. All in one of three carbonated flavors as they have Strawberry Watermelon, Lemon Lime Fizz, and Cherry Vanilla (which will be a Walmart exclusive).

C4 Has Launched Three New Sparkling Protein Flavors

For more than two decades, Nutrabolt has helped consumers train harder, perform better, and achieve their goals through category-leading innovation across pre-workout, energy, hydration, and recovery. With the introduction of C4 Sparkling Protein, the brand continues its evolution and builds upon C4's established protein lineup, meeting growing consumer demand for convenient, enjoyable nutrition solutions that fit seamlessly into everyday life. C4 Sparkling Protein offers a refreshing alternative to traditional protein shakes while further expanding the brand's beverage portfolio.

"More people than ever are prioritizing protein as part of their wellness routines, but they don't want to sacrifice taste to get it," said Emily Hoyle, Senior Vice President of Marketing at Nutrabolt. "Sparkling and clear protein drinks have a reputation for tasting flat or leaving behind a chalky mouthfeel, and we knew that wasn't good enough for C4. We took our best-in-class flavor expertise and applied it to this new format, so consumers get a protein beverage that's as enjoyable to drink as it is functional. It's another example of how we're expanding the C4 portfolio beyond energy to support a broader performance lifestyle."
