New ready-to-drink beverage delivers 20 grams of protein, zero sugar, no caffeine, and a refreshing sparkling format designed for today’s active consumer
AUSTIN, Texas, July 30, 2026 /PRNewswire/ — C4®, one of the fastest-growing brands in energy drinks and sports nutrition and a cornerstone of the Nutrabolt portfolio of performance brands, today announced the launch of C4 Sparkling Protein, a caffeine-free, ready-to-drink beverage that brings a new experience to the protein category. Delivering 20 grams of high-quality protein, zero sugar, and five essential vitamins and minerals in a crisp, carbonated format, C4 Sparkling Protein offers a refreshing alternative to traditional protein shakes while further expanding the brand’s beverage portfolio.
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.
“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.”
Inspired by fan-favorite flavor profiles, C4 Sparkling Protein is available in:
- Cherry Vanilla (Walmart Exclusive)
- Strawberry Watermelon
- Lemon Lime Fizz
The launch builds on C4’s established sports nutrition heritage while introducing a differentiated protein offering designed for consumption anytime, anywhere, whether after a workout, between meals, or throughout the day.
C4 Sparkling Protein ($27.99) is available online at C4 Supps and in store at Walmart, with Amazon availability coming soon.
