Plain water is the single best drink for acid reflux. It’s neutral, calorie-free, and helps dilute stomach acid without triggering further production. But beyond water, several other beverages can soothe symptoms or at least avoid making them worse, while a handful of common drinks are worth cutting back on. Here’s what works, what doesn’t, and why.
Why Your Drink Choice Matters
When liquid enters your stomach, it relaxes to accommodate the volume. The larger that volume, the faster the stomach tries to empty, but it also increases pressure inside the stomach. That pressure can force the muscular valve between your stomach and esophagus (called the lower esophageal sphincter) to relax at the wrong time, letting acid splash upward. Drinks that are acidic, carbonated, or high in fat make this problem worse by either irritating the esophageal lining directly or further weakening that valve.
A study published in the Journal of Gastroenterology and Hepatology tested this directly. GERD patients who consumed 600 mL liquid meals (about 20 ounces) had nearly twice as many reflux episodes as when they drank 300 mL portions (about 10 ounces) spread across six smaller sittings. The takeaway: what you drink matters, but so does how much you drink at once.
Water and Alkaline Water
Room-temperature still water is the safest default. It rinses acid from the esophagus, dilutes what’s sitting in the stomach, and doesn’t introduce anything that could trigger more acid production. Sipping throughout the day rather than gulping large amounts at meals helps keep stomach volume manageable.
Alkaline water, which has a pH of 8.8 or higher, may offer an extra benefit. Research from Harvard-affiliated investigators found that water at that pH level can inactivate pepsin, a digestive enzyme that damages the esophageal lining when it travels upward with refluxed acid. Regular tap water typically has a pH around 7, so it doesn’t have this effect. If you want to try alkaline water, look for brands that list a pH of 8.8 or above on the label. It’s not a replacement for other management strategies, but it can complement them.
Herbal Teas That Help
Caffeine-free herbal teas are some of the most soothing options for reflux. Chamomile, ginger, and fennel teas all have anti-inflammatory properties that can calm an irritated esophagus.
Chamomile is a particularly good choice before bed, since nighttime reflux tends to be more damaging (you’re lying flat, and you swallow less frequently while asleep). Drinking a cup after dinner or before sleep may reduce inflammation in the esophageal lining. Ginger tea helps in a different way: it supports gastric motility, meaning it encourages your stomach to empty more efficiently, which reduces the window for acid to reflux upward. Turmeric tea also shows promise for its anti-inflammatory compounds, though it has a strong flavor that not everyone enjoys.
One caution: peppermint tea is often recommended as a digestive aid, but the American College of Gastroenterology lists peppermint as a GERD trigger. It relaxes the lower esophageal sphincter, which is the opposite of what you want. Skip it.
Plant-Based Milks Over Whole Dairy
A cold glass of milk feels soothing going down, but full-fat dairy can backfire. Fat is one of the strongest triggers for valve relaxation at the top of the stomach, and whole milk delivers about 8 grams of it per cup. That temporary coating sensation gives way to increased acid production shortly after.
Almond milk and soy milk are better alternatives. They contain only 2 to 4 grams of fat per cup, and those fats are mostly the unsaturated type, which is less likely to provoke reflux. Almond milk is also naturally alkaline, giving it a slight edge. If you prefer cow’s milk, skim is the safest option since it has negligible fat. Avoid chocolate milk entirely, as both the fat and the chocolate are independent reflux triggers.
Aloe Vera Juice
Aloe vera juice has a long folk reputation as a digestive soother, and there’s some science to support it for reflux. The key is choosing the right product: only decolorized and purified aloe vera juice is safe to drink. Non-decolorized versions contain anthraquinone, a compound that acts as a potent laxative and intestinal irritant, which will create new problems rather than solving old ones.
If you want to try it, start small. Research has examined doses around 50 milligrams per day, roughly equivalent to about 2 tablespoons. Give yourself a few days to see how your body reacts before increasing the amount. Pregnant people should avoid aloe vera juice entirely, as should anyone taking diuretics or laxatives, since it can interact with both.
Drinks to Limit or Avoid
Some beverages are reliable reflux triggers for most people. The American College of Gastroenterology identifies coffee, chocolate-based drinks, and alcohol as common culprits. Coffee is a double hit: caffeine relaxes the esophageal valve, and coffee’s natural acidity irritates tissue that’s already inflamed. If you’re not willing to quit coffee entirely, switching to a low-acid, cold-brew variety and keeping it to one small cup may reduce the impact.
Citrus juices (orange, grapefruit, lemon) and tomato juice are highly acidic and can directly irritate a damaged esophageal lining. Even if they don’t trigger a full reflux episode for you, they can worsen the burning sensation when the lining is already inflamed.
Carbonated beverages deserve special attention. The carbon dioxide gas expands in the stomach, increasing pressure and triggering more frequent valve relaxations. Studies have shown that carbonated drinks significantly reduce lower esophageal sphincter pressure compared to flat versions of the same liquid. This applies to sparkling water, sodas, and carbonated flavored drinks alike. The carbonation itself is the issue, not just the sugar or caffeine that may come with it.
How You Drink Matters Too
Even the best beverage can trigger reflux if you drink too much at once. The research on meal volume and reflux is clear: larger volumes stretch the upper portion of the stomach and directly increase the number of reflux episodes. Patients in the 600 mL group experienced a total acid reflux time of 12.5%, compared to 5.5% in the 300 mL group. That’s more than double the acid exposure from simply drinking more at each sitting.
A few practical habits that help: sip rather than gulp, aim for smaller amounts more frequently rather than large drinks with meals, and stay upright for at least 20 to 30 minutes after drinking anything substantial. If you tend to wake up with reflux, stop all liquids at least two hours before lying down. These timing adjustments often make as much difference as choosing the right drink in the first place.
