C4 has expanded its functional beverage lineup with the rollout of C4 Sparkling Protein, a caffeine-free, carbonated ready-to-drink (RTD) protein beverage.
Delivering 20 grams of high-quality protein, along with five essential vitamins and minerals, the product marks C4's entry into the sparkling protein segment, extending the brand's reach beyond its core energy drink and pre-workout focus.
Flavour Portfolio
The C4 Sparkling Protein lineup is entering the market with three distinct SKU variations featuring carbonated fruit and dessert-inspired profiles:
🍒 Cherry Vanilla: A classic sweet-and-creamy flavour profile distributed as a Walmart retail exclusive.
🍓 Strawberry Watermelon: A refreshing, fruit-forward carbonated protein combination.
🍋 Lemon Lime Fizz: A citrus-infused carbonated beverage engineered for crisp, sparkling refreshment.
Carbonated Protein Formulation
The development of C4 Sparkling Protein addresses standard formulation challenges in clear, carbonated protein drinks, where products often exhibit flat taste profiles or a chalky mouthfeel. By applying its flavour-engineering capabilities to a carbonated matrix, the business aims to provide an accessible, refreshing alternative to traditional, thick protein shakes.
Formulated without sugar or caffeine, the RTD beverage is engineered for versatile consumption occasions across daily routines, including post-workout recovery, midday snacking, and general dietary protein supplementation.
Emily Hoyle, Senior Vice President of Marketing at Nutrabolt, stated that the brand applied its flavour expertise to the new format to ensure the carbonated protein beverage delivers both functional nutrition and sensory appeal as C4 extends into broader performance lifestyle categories.
Retail Availability and Pricing
The C4 Sparkling Protein range has commenced commercial availability directly through C4's direct-to-consumer e-commerce platform at a retail price of US$27.99 per pack, alongside physical retail distribution across Walmart stores nationwide.
The range is scheduled to expand its digital retail footprint through Amazon in upcoming distribution waves.
