Prebiotic drinks, including prebiotic sodas, are popping up on social media and taking over shelves in stores from Whole Foods to Walmart. Adding functional fibers to fizzy favorites may sound like a recipe for a robust
microbiome, but is prebiotic soda good for you, or are the purported benefits all just hype?
First, what is prebiotic soda?
Prebiotic sodas are marketed as healthier soda alternatives enriched with one or more plant fibers. Most brands contain soluble fiber, which doesn't break down during digestion. Instead, it passes into the large intestine, where gut microbes feed on it and produce byproducts like short-chain fatty acids (SCFAs).
Inulin is the most common type of fiber in prebiotic soda. Made up of a chain of fructose molecules, this soluble fiber usually comes from sources like chicory root and agave. One popular brand combines several different types of fiber from chicory, marshmallow root, cassava and nopal cactus to provide a diverse range of prebiotics.
Prebiotic soda benefits
Consuming prebiotics is associated with several health benefits due to how they affect the gut microbiome. Soluble fiber increases microbiome diversity, which is correlated with
lower instances of chronic disease and better overall health.
† Increased prebiotic fiber intake is also associated with
lower inflammation.
† This could be due to the anti-inflammatory effects of SCFAs or the interplay between some microbes
and the immune cells that line the gut.
†
SCFAs can have beneficial immune effects in other areas of the body. These compounds interact with innate and adaptive immune cells to maintain balance and strengthen responses to infections.
† SCFAs also
protect against intestinal permeability ("leaky gut"), which can help prevent pathogens and proteins from entering the bloodstream and triggering allergic reactions.

Okay, so what about actually drinking prebiotic soda?
Although science shows widespread correlations between prebiotics and gut health,
evidence for specific prebiotic soda benefits is lacking.
Part of the problem may be how prebiotic drink
processing methods affect the amount of fiber in the final product. And sodas enriched with prebiotics contain far fewer types of fiber than whole plant foods, the natural source of prebiotics. In fact, diversity of plants—not functional beverage consumption—is one of the
most reliable predictors of a healthy microbiome, largely due to the high fiber content of these foods.
Are there any side effects of drinking prebiotic soda?
Some prebiotic drinks can have as much as nine grams of fiber per 12-ounce can, more than half of what most Americans get in their daily diets. Such a rapid increase in fiber intake can cause:
- Gas
- Bloating
- Cramping
- Constipation
- Loose stools
- Uncomfortable feelings of fullness
Gasses produced as gut bacteria break down fibers like inulin may
worsen symptoms of IBS or cause gastrointestinal distress in people with
FODMAP sensitivities.
Since chicory is part of the daisy family, you may be at risk of allergic reaction from prebiotic sodas if you also react to
daisies, dandelions, sunflowers or chamomile. Chicory has additional potential to cross-react with birch pollen and
trigger symptoms of oral allergy syndrome in people with seasonal allergies.
How to choose the right prebiotic soda for you
If you don't have allergies or a condition like IBS, prebiotic soda can be an enjoyable alternative to traditional soda. Many brands offer classic flavors like cola, root beer, and ginger—as well as
fun new combinations to try.
Pay attention to ingredients as you compare brands. The healthiest prebiotic sodas are free from:
- Excessive sugar
- Artificial sweeteners
- Artificial colors
- Artificial flavors
- Chemical additives
Keep in mind that switching to drinks with prebiotics may not provide the gut health benefits that some brands profess. If your goal is a healthier microbiome, consider a more widespread dietary change that includes replacing sugary drinks and ultra-processed foods with high-fiber options like fruits, vegetables, beans and whole grains.
Choosing
prebiotic soda may have benefits unrelated to the fiber content that make it worth the switch. Many brands use less sugar than traditional soda or add alternative sweeteners like monk fruit, which can help
reduce your sugar intake if you're trying to cut back on sweetened beverages.
So, should you switch to prebiotic soda?
Swapping regular soda for a lower-sugar drink infused with prebiotics can add more fiber to your diet and possibly improve your
gut health. However, science hasn't yet demonstrated that drinking soda can have the same microbiome-boosting effects as eating high-fiber foods. So
pack your plate with plants, and enjoy prebiotic soda as a tasty treat when you're in the mood for a healthier alternative with classic soda flavor.
