People are increasingly turning to prebiotic sodas, marketed as healthy fizzy drinks with gut-boosting benefits. Leading the movement are brands Poppi and Olipop, whose popularity is rapidly growing.

It seems Coca-Cola has grown sick of stomaching Poppi and Olipop’s success with “gut-healthy” sodas – so the legacy brand is launching its own prebiotic drinks. Coca-Cola’s Simply prebiotic sodas will be sold in five fruity flavors: Strawberry, Pineapple Mango, Fruit Punch, Lime and Citrus Punch.

Prebiotic sodas are all the rage right now, with brands such as Daytrip, Poppi, and Olipop dominating the market for “healthy” soda drinks.
