Fizztein

Fizztein is a better-for-you beverage brand producing clean-label sparkling protein drinks designed for everyday refreshment. The company's flagship product line consists of protein seltzers that combine whey protein isolate with real fruit juice and light carbonation, offering a compelling alternative to traditional protein shakes, chalky powders, and conventional sparkling water beverages. Each 12 fl oz can delivers 8 grams of protein, 90 calories, and 11 grams of natural sugar, with zero added sugar and no artificial ingredients. The formulation is notably minimal: carbonated filtered water, whey protein isolate, and real fruit juice concentrates — with no gums, stabilizers, citric acid, stevia, or artificial sweeteners. Fizztein launches with a core lineup of three fruit-forward flavors, including a Mango Peach variety made with mango puree concentrate, apple juice concentrate, peach juice concentrate, and lemon juice concentrate. Additional flavors are planned as the brand scales. The product is shelf-stable and suitable for room-temperature storage, though best enjoyed cold. Fizztein positions its drinks as appropriate for a wide range of consumption occasions beyond the gym — including post-workout recovery, afternoon energy needs, and casual social settings — targeting busy consumers such as students, parents, and health-conscious individuals who want functional refreshment without the heaviness of traditional protein beverages. The brand emphasizes transparent, clearly labeled packaging so consumers can easily identify every ingredient. Its clean-label ethos and minimal ingredient deck differentiate it in a crowded better-for-you beverage market. Fizztein competes in the intersection of the functional beverage, protein supplement, and sparkling water categories, appealing to CPG retail and direct-to-consumer channels.
