Juice has a reputation for loading kids up with sugar disguised as something wholesome, but Frosh is shaking things up with a protein-packed, real fruit juice formula that finally makes reaching for a juice box feel like a genuinely good choice. These feel-good juice boxes entice parents with five grams of protein, plus B vitamins and immune support benefits.
Frosh's protein juice dropped in vibrant varieties like Mighty Apple, Tropic Blast (featuring apple juice, orange juice and pineapple juice concentrates) and Power Punch, each made to fuel growing, active kids during school, after games, and moments in between that demand fruity, hard-working refreshment. Notably, because the juices contain whey protein isolate, they contain milk, but exclude other major allergens like gluten, soy, tree nuts, and peanuts.

Trend Themes
-
Protein-infused Kids Beverages — A rising category of juice-based drinks with added whey protein isolate positions beverages as snackable nutrition for children rather than just treats.
-
Clean-label Functional Drinks — Consumers are favoring real-fruit concentrates and minimal-ingredient lists combined with targeted functional benefits like B vitamins and immune support.
-
Allergen-conscious Fortified Foods — Products that deliver heightened nutrition while explicitly excluding common allergens create opportunities for inclusive family-focused nutrition offerings.
Industry Implications
-
Packaged-beverage — Shelf-stable single-serve formats that blend fruit juices with protein create a new subcategory between traditional juices and ready-to-drink protein beverages.
-
School-food-service — Reformulated juice options with added protein and immune-support nutrients can shift procurement toward items framed as both appealing to kids and nutritionally substantive.
-
Youth-sports-nutrition — Portable, low-allergen protein drinks sized for children address post-activity recovery needs without invoking adult product conventions.
