Fizztein introduced its Protein Seltzer, a bubbly ready-to-drink that blends carbonated water with premium whey isolate and real fruit juice, featuring 8g of protein and no added sugar. The recipe intentionally skips gums, stevia and artificial ingredients to preserve a crisp, sparkling water–style texture rather than a thick protein shake.
The range arrives in three fruity flavors: Pineapple, Mango Peach and Mixed Berry, each delivering 8g protein, 11 to 13g of carbohydrates and roughly 80 or 90 calories per can. Packaging is sold in four-packs priced at $15.99, and the formulation emphasizes an authentic juice taste while keeping the mouthfeel light and effervescent.
Fizztein offers a lighter take on protein RTDs that fits social sipping, workouts or on-the-go hydration without the heaviness of milk-based drinks. Its clear, carbonated format makes protein more approachable and extends the beverage category toward multisensory, flavor-forward options.
