When the heat rises, nothing sounds better than a refreshing slushie. But most store-bought slushies are loaded with sugar and lack any real nutrition. These gut-friendly summer slushies are hydrating, fiber-filled, and help keep kids cool while also supporting digestion and regular pooping.

Why These Slushies Support Digestion

  • Fiber + Prebiotics: Fruits like berries, kiwi, and pears contain natural fibers that support stool softness and gut motility.

  • Hydration: Staying hydrated helps fiber do its job in the colon, keeping things moving.

  • Natural Stool-Supporting Ingredients: Some fruits, like kiwis have clinically studied effects on improving stool frequency and softness (1).
