Does Kombucha Help With Bloating?

If you have ever felt uncomfortably full and puffy after a meal, you have probably looked for something that helps. Kombucha is often talked about as a natural remedy for bloating. The short answer is yes, kombucha can help some people with bloating. But it does not work for everyone. In some cases, it can even make bloating worse. The difference comes down to what causes your bloating and what is actually in your bottle.

What Causes Bloating in the First Place?

Bloating is not one single problem. It has several possible causes. The most common is gas trapped in your digestive tract. This happens when you eat too fast, swallow air, or eat foods that are hard to digest. Another cause is water retention. Your body holds onto extra fluid when you eat too much salt or when your hormones shift.

A third cause is gut bacteria imbalance. When the bacteria in your colon are not working well, they produce more gas as they ferment food. This is where kombucha gets its reputation. The idea is that the good bacteria in kombucha can help rebalance your gut. But evidence for this claim is mixed.

Research published in Frontiers in Microbiology has shown that fermented foods can increase gut microbiome diversity. But the studies are small and the results vary from person to person. What works for one person may do nothing for another.

Does Kombucha Help With Bloating?

Kombucha contains probiotics. These are live bacteria that can survive your stomach acid and reach your colon. Some studies suggest that probiotics can reduce bloating in people with irritable bowel syndrome (IBS). A 2021 review in Nutrients found that certain probiotic strains helped with bloating and gas. But the strains in kombucha are not the same ones used in those studies.

Kombucha also contains organic acids. These include acetic acid, which is also found in vinegar. Some people report that these acids help with digestion by increasing stomach acid. Low stomach acid can cause food to sit in your stomach too long, leading to bloating. If this is your issue, the acids in kombucha may help.

But there is a catch. Kombucha is also carbonated. The bubbles come from the fermentation process. Drinking carbonated beverages can trap gas in your stomach and make bloating worse. So kombucha may help some people and hurt others depending on how your body handles carbonation.

What Does the Research on Kombucha and Bloating Actually Say?

There is no large clinical trial that specifically tested kombucha for bloating. Most of the evidence comes from studies on fermented foods in general. A 2023 study in Cell looked at how fermented foods affect the gut microbiome. The researchers found that people who ate fermented foods had lower markers of inflammation. But they did not measure bloating directly.

The National Center for Complementary and Integrative Health states that probiotics can help with some digestive issues. But they also note that the effects are strain-specific. This means the probiotics in one brand of kombucha may not be the same as in another. Some brands pasteurize their kombucha, which kills the live bacteria. Others add extra probiotics after fermentation.

What this means for you is simple. If you buy kombucha off the shelf, the probiotic content is not guaranteed. Some bottles have very few live bacteria. Others have many. The only way to know is to check the label for live cultures and avoid pasteurized versions.

How Does Kombucha Compare to Other Remedies for Bloating?

Kombucha is not the only option. Table below compares it to other common remedies based on what the evidence shows.

Notice that kombucha is not the top choice for any specific type of bloating. It is a general option that may help some people. If you have chronic bloating, a targeted probiotic supplement with a known strain is more likely to work. But if you enjoy kombucha and it does not make you feel worse, it is a reasonable addition to your diet.

When Can Kombucha Make Bloating Worse?

Kombucha is not harmless for everyone. Some people find it makes their bloating worse. Here are the main reasons why.

• Carbonation: The bubbles can cause gas to build up in your stomach. This is the most common reason kombucha causes bloating.
• FODMAPs: Kombucha is made from tea and sugar. The fermentation process can create short-chain carbohydrates called FODMAPs. Some people are sensitive to these and they can cause gas and bloating.
• Histamine: Fermented foods contain histamine. If you have histamine intolerance, kombucha can cause bloating along with other symptoms like headaches or skin flushing.
• Too much too fast: Starting with a large amount of kombucha can overwhelm your gut. The sudden influx of bacteria can cause temporary bloating as your gut adjusts.

If you have not tried kombucha before, start with a small amount. Two to four ounces per day is a reasonable starting point. If you feel more bloated after drinking it, stop and try a different approach.

What to Look for When Buying Kombucha for Bloating

Not all kombucha is the same. If you want to try it for bloating, pay attention to these factors.

Live cultures: Look for “raw” or “unpasteurized” on the label. Pasteurization kills the probiotics. Some brands also list the specific strains they use. Strains like Lactobacillus and Bifidobacterium have the most evidence for digestive health.

Low sugar: Some kombucha brands add a lot of sugar after fermentation. Extra sugar can feed unhealthy gut bacteria and make bloating worse. Aim for brands with less than 5 grams of sugar per serving.

Low carbonation: Some brands are less fizzy than others. If carbonation bothers you, look for a still or low-fizz version. You can also let the bottle sit open for a few minutes to let some gas escape before drinking.

No added flavors: Flavored kombuchas often have fruit juices or extracts that can add FODMAPs. Plain or ginger-flavored kombucha is usually the safest bet for sensitive stomachs.

Common Misconceptions About Kombucha and Bloating

There is a lot of hype around kombucha. Some claims are not backed by evidence. Here are the most common ones you should ignore.

“Kombucha cures bloating.” No single food or drink cures bloating. Bloating has many causes and kombucha only addresses one possible factor. If your bloating is from constipation, food sensitivities, or stress, kombucha will not fix it.

“More kombucha is better.” Drinking large amounts of kombucha can backfire. Too much can cause digestive upset, including bloating. Stick to one serving per day at most.

“All kombucha has probiotics.” Many store-bought kombuchas are pasteurized. Pasteurization kills the live bacteria. Check the label. If it says “pasteurized” or “heat-treated,” it does not contain live probiotics.

“Kombucha works for everyone.” Individual responses vary widely. Some people feel great after drinking it. Others feel worse. The only way to know is to try it carefully and pay attention to how you feel.
