# Sparkling Protein Water Cans Fizztein's Protein Seltzer Is Fruit-Forward By Amy Duong | Written with AI assistance | Published 2026-09-16 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/protein-seltzer-trend References: [stack3d](https://www.stack3d.com/2026/09/introducing-fizztein-protein-seltzer)  Fizztein introduced its Protein Seltzer, a bubbly ready-to-drink that blends [carbonated water with premium whey isolate](https://www.trendhunter.com/trends/clear-protein-drink) 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](https://www.trendhunter.com/trends/clear-protein-water) that fits social sipping, workouts or on-the-go hydration without the heaviness of milk-based drinks. Its [clear, carbonated format](https://www.trendhunter.com/trends/sparkling-clear-protein-drinks) makes protein more approachable and extends the beverage category toward multisensory, flavor-forward options.
