About Fizzen
Fizzen is a sparkling protein drink brand co-founded by Kristin Cavallari, built around real fruit juice, whey protein isolate, collagen peptides, and B vitamins. It’s not chasing the hardcore gym cooler. Fizzen is going after the wellness-lifestyle crowd that wants protein without the chalky shake routine.
About Fizzen
Fizzen sits in the growing middle ground between sparkling juice, functional beverage, and light protein RTD. The brand’s core pitch is simple: protein should taste like fruit, not like a gym bag.
That matters because most protein drinks still feel like fitness products first. Fizzen flips the order. The drink leads with fruit-forward flavors and carbonation, then works the functional angle underneath with 8g of whey protein isolate, 5g of collagen peptides, and 100% DV of vitamins B12 and B6 per 12 fl oz can.
The current lineup includes Strawberry Lemonade, Orange Pineapple, Fruit Punch, and Peach Mango. Every flavor uses carbonated water, real fruit juice, whey protein isolate, collagen peptides, natural flavors, citric acid, vitamin B12, and vitamin B6. The drinks contain dairy, have no caffeine, and are positioned more like an everyday grab-and-go protein boost than a pre-workout or energy drink.
Built With Kristin
Kristin Cavallari gives Fizzen a different kind of launch energy. She’s not new to consumer products. After MTV fame from Laguna Beach and The Hills, Cavallari built Uncommon James into a lifestyle brand spanning jewelry, beauty, home, and fashion.
That background fits Fizzen’s lane. This isn’t a brotein play. It’s clean-label-ish, beauty-adjacent, fruit-forward, and built for someone who wants protein after school drop-off, after Pilates, during a workday, or instead of another plain sparkling water.
The Target launch also gives Fizzen immediate mainstream visibility. A celebrity-backed functional drink can die fast if the product feels like merch. Fizzen has a clearer reason to exist: lighter protein, real fruit flavor, collagen, and bubbles in a format that doesn’t feel like punishment.
Fizzen is for the protein-curious consumer who doesn’t want a milkshake, an energy drink, or a supplement disguised as a beverage. It’s a lifestyle protein drink with enough function to matter and enough refreshment to avoid the usual protein-drink fatigue.
