C4 Debuts Sparkling Protein Drink for Active Consumers

C4, a fast-growing brand from Nutrabolt known for its energy drinks and performance supplements, has launched C4 Sparkling Protein, a caffeine-free, ready-to-drink beverage that contains 20 grams of ultra-filtered clear whey protein, zero sugar, and five essential vitamins and minerals.

The company said C4 Sparkling Protein builds on its existing protein lineup, meeting growing consumer demand for convenient, enjoyable nutrition solutions that fit 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 and in store at Walmart, with Amazon availability coming soon.
