Several drinks can help relieve bloating, with peppermint tea, fennel tea, and plain water sitting at the top of the evidence-backed list. The right choice depends on what’s causing your bloating, whether that’s trapped gas, water retention from too much sodium, or sluggish digestion. Here’s what actually works and why.
Peppermint Tea
Peppermint tea is one of the most effective drinks for bloating caused by gas or intestinal cramping. The menthol in peppermint oil works by blocking calcium from entering the smooth muscle cells that line your digestive tract. When those muscles can’t take in calcium, they relax instead of contracting. This mechanism is similar to how certain blood pressure medications work on blood vessels, and the result is less spasming, less cramping, and easier passage of trapped gas.
Peppermint oil doesn’t just quiet one type of contraction. It reduces the gut’s response to multiple chemical signals that trigger tightening, which is why it tends to work whether your bloating feels like pressure, sharp cramps, or a general fullness that won’t go away. Steep your tea for at least five minutes to extract more of the active oils, and drink it warm. If you experience acid reflux, peppermint can sometimes make that worse by relaxing the valve between your stomach and esophagus, so ginger tea may be a better option for you.
Fennel Tea
Fennel has been used as a digestive remedy for centuries, and the science supports it. The essential oil in fennel seeds is rich in a compound called trans-anethole, which gives fennel its licorice-like flavor and provides both carminative (gas-reducing) and antispasmodic effects. Research on stomach motility shows fennel tea has region-specific effects on how the stomach moves, meaning it can influence the pace of digestion in targeted ways rather than simply slowing or speeding everything up.
To prepare it effectively, use about 2.5 grams of fennel seeds (roughly one teaspoon) steeped in 150 milliliters of boiling water for a full 15 minutes with the cup covered. Strain out the seeds and let it cool slightly before drinking. That 15-minute steep time matters because it allows more of the essential oils to dissolve into the water. Shorter steeping produces a milder, less effective tea. Fennel tea is a particularly good choice after a heavy meal or when you feel bloated from foods like beans, cruciferous vegetables, or dairy.
Plain Water
Sometimes the simplest fix is the most overlooked. If your bloating is related to water retention, especially after a salty meal, drinking more water helps your body flush out the excess sodium that’s causing you to hold onto fluid. It sounds counterintuitive, but dehydration signals your body to retain water, making bloating worse. Staying well hydrated keeps things moving through your digestive tract and helps break down food so nutrients absorb more efficiently.
There’s no need to overthink the timing. Drinking water with meals does not dilute your digestive fluids or interfere with digestion. Water actually supports the breakdown of food and helps your body absorb what it needs. If you prefer warm water, that’s fine too, but temperature doesn’t make a significant difference for bloating specifically.
Lemon Water
Adding lemon to your water won’t transform it into a bloating cure, but it can help in a couple of indirect ways. The citric acid in lemon may gently support digestion, and people who add lemon to water tend to drink more of it overall, which circles back to the hydration benefit. If sodium-driven water retention is your main issue, lemon water is a pleasant way to increase your fluid intake without adding sugar or artificial sweeteners that can contribute to gas.
That said, lemon water works primarily because it’s water. Don’t expect dramatic results from the lemon itself. If you enjoy the taste and it helps you drink more throughout the day, that alone makes it worthwhile.
Fermented Drinks Like Kefir
Fermented drinks, including kefir and other cultured dairy or non-dairy beverages, contain live bacteria that can improve the balance of your gut microbiome over time. A 2025 meta-analysis of clinical trials found that consuming fermented foods significantly reduced bloating compared to control groups. The effect was most pronounced with products containing a mix of beneficial bacteria, particularly combinations that included strains of Bifidobacterium and Lactobacillus.
The catch is timing. These aren’t quick fixes. Studies showed improvements at the two-week mark in some cases, but many trials ran for four to eight weeks before meaningful changes appeared. If you’re dealing with chronic, recurring bloating rather than a one-time post-meal event, incorporating a daily serving of kefir or another fermented drink could help. Start with small amounts, since fermented foods can temporarily increase gas as your gut adjusts to the new bacterial population.
Ginger Tea
Ginger has well-documented effects on nausea and gastric motility. It helps the stomach empty faster, which can reduce the heavy, distended feeling that comes with slow digestion. Ginger also has mild anti-inflammatory properties in the gut. For bloating specifically, it’s most useful when you feel full long after eating or when your bloating comes with nausea. Fresh ginger sliced thin and steeped in hot water for 10 minutes produces a stronger tea than dried ginger powder, though both work.
What About Apple Cider Vinegar?
Apple cider vinegar is one of the most popular home remedies for bloating, but the evidence behind it is thin. There are no strong clinical studies showing it improves digestion or reduces bloating in a measurable way. The theory that it boosts stomach acid levels hasn’t been confirmed in research.
If you want to try it anyway, dilution is critical. Mix no more than one tablespoon into eight ounces of water or tea. Drinking it undiluted or in concentrated amounts can erode tooth enamel, damage the lining of your esophagus, and actually cause stomach upset, the opposite of what you’re going for.
Skip the Sparkling Water
Carbonated water, including sparkling water and seltzer, introduces carbon dioxide gas directly into your digestive system. For some people this causes belching that provides temporary relief, but for many others it adds to the problem by increasing gas and abdominal pressure. If you already deal with bloating regularly, or if you have acid reflux, carbonated beverages of any kind are likely to make things worse. Stick to still water or herbal tea instead.
How to Get the Most Relief
The best approach combines the right drink with a few practical habits. Peppermint or fennel tea after meals can prevent gas from building up. Staying hydrated throughout the day, especially after salty foods, helps prevent the fluid-retention type of bloating. For chronic bloating that shows up most days, a daily fermented drink may gradually shift things in the right direction over several weeks.
Pay attention to which type of bloating you experience most often. Gas-related bloating (sharp, crampy, relieved by passing gas) responds best to peppermint and fennel. Puffy, water-retention bloating (worse after salty food, often accompanied by tight rings or sock marks on your ankles) responds best to increased water intake and reduced sodium. Fullness that lingers for hours after eating points to slow gastric emptying, where ginger tea tends to help most. Matching the drink to the cause makes a noticeable difference.
