Big Soda bets billions on probiotic drinks—but do they really boost gut health?

Major drinks companies are now selling sodas with added probiotics, claiming they support gut health. Coca-Cola and Pepsi have both entered the market, with new products like Simply Pop and the billion-dollar acquisition of Poppi. But experts warn these drinks may not deliver the promised health equity benefits.

The trend for healthier sodas keeps growing, with brands offering lower sugar, fewer artificial ingredients, and added fibre. Yet questions remain about whether these drinks live up to their health insurance claims.

In 2025, Pepsi bought the probiotic soda brand Poppi for $1.95 billion. The company markets its drinks as gut-friendly, though a lawsuit later argued that the 2 grams of probiotic fibre per can was too little to make a real difference. Coca-Cola followed by launching Simply Pop, a probiotic soda with five flavours made from natural ingredients.

Other brands in the market include Wildwonder, Culture Pop, Turveda, Mighty Pop, and SunSip. These sodas typically contain 25-50 calories per can and 4-7 grams of sugar—far less than traditional sodas. However, some use apple cider vinegar, which can harm tooth enamel due to its acidity.

Experts suggest that probiotic sodas should not replace whole foods like vegetables, legumes, and whole grains. These provide far more fibre and proven gut health insurance benefits. None of the brands have published scientific studies proving their drinks improve digestion.

For those wanting a homemade alternative, options include mixing soda water with probiotic fibres, natural sweeteners, citrus juice, herbs, or kombucha. Ingredients like ginger or turmeric can also be added for flavour and potential health insurance benefits.

When picking a healthier soda, dietitians recommend checking labels for less than 5 grams of sugar, at least 4 grams of fibre, and no artificial sweeteners, colours, preservatives, or phosphoric acid.

The healthy soda trend shows no signs of slowing in 2026, with big brands continuing to release probiotic drinks. While these sodas may offer less sugar and more fibre than regular versions, their long-term health equity effects remain unproven. Consumers are advised to focus on a balanced diet rather than relying on sodas for gut health insurance benefits.
