Water is the single best drink for acid reflux, and switching to it from coffee, soda, or citrus juice can make a noticeable difference on its own. But beyond plain water, several other beverages can actively help neutralize acid or reduce the conditions that trigger reflux. What you avoid drinking matters just as much as what you choose.
Plain Water and Alkaline Water
Still water at room temperature is the safest, simplest choice. It dilutes stomach acid, helps clear acid from the esophagus, and has no ingredients that could make things worse. Sipping water between meals rather than gulping large amounts during a meal is generally the better approach, since a very full stomach increases pressure and can push acid upward.
Alkaline water with a pH of 8.8 offers an extra benefit. At that pH level, it helps neutralize pepsin, one of the digestive enzymes your stomach produces. During reflux episodes, pepsin can get lodged in the tissues of your esophagus and continue causing irritation even after the burning sensation fades. Alkaline water deactivates that enzyme in a way regular water does not. You can find bottled alkaline water at most grocery stores, or use a home filtration system that raises pH.
Ginger Tea
Ginger has a specific mechanism that makes it useful for reflux: it promotes faster gastric emptying. That means food moves from your stomach into your small intestine more quickly. Once food leaves your stomach, your stomach no longer needs to produce as much acid to digest it, which reduces the chance of acid flowing back up into your esophagus.
Brewing fresh ginger slices in hot water for 10 to 15 minutes gives you a simple, caffeine-free tea. Keep it unsweetened or lightly sweetened with honey. Avoid store-bought ginger ales, which are carbonated, often contain very little real ginger, and are loaded with sugar.
Plant-Based Milks
Not all plant milks are equal when it comes to reflux. Almond milk and soy milk are both alkaline-forming, meaning they help shift your body’s pH in a direction that counteracts acidity. Oat milk, on the other hand, is acid-forming because oats are inherently acidic grains. If you’re choosing a milk alternative specifically for reflux, almond or soy is the better pick.
Cow’s milk is a common source of confusion. A cold glass of whole milk might feel soothing at first, but the fat content can relax the valve between your stomach and esophagus, ultimately making reflux worse. If you prefer dairy, fat-free or low-fat milk is a safer option. With any milk, unsweetened versions are best since added sugars can contribute to bloating.
Coconut Water
Unsweetened coconut water is naturally rich in potassium and other electrolytes that promote pH balance in the body. It’s mildly alkaline, gentle on the stomach, and hydrating. The key word is unsweetened. Flavored or sweetened coconut waters often contain added sugars or citric acid that can undermine the benefits. Check the label and look for varieties with no added ingredients.
Aloe Vera Juice
A small pilot study published in the Journal of Traditional Chinese Medicine tested aloe vera syrup at a dose of 10 milliliters per day (about two teaspoons) and found it reduced heartburn symptoms in people with GERD. That’s a modest amount. Aloe vera juice designed for drinking is widely available, but choose products labeled “decolorized” or “purified,” since unprocessed aloe contains compounds that act as laxatives. Start with a small amount to see how your body responds.
Low-Acid Juices
Most fruit juices are a problem for reflux because they’re highly acidic. Orange juice, grapefruit juice, and tomato juice are among the worst offenders. But not all juices fall into that category.
Carrot juice, beet juice, and watermelon juice are lower on the acidity scale. Watermelon is especially useful because its high water content helps dilute stomach acid. Cabbage juice is another option some people find soothing, though the taste takes some getting used to. If you’re buying juice rather than making it, look for varieties without added citric acid, which manufacturers often use as a preservative and which can trigger reflux on its own.
What Not to Drink
Carbonated beverages are one of the biggest reflux triggers, and the reason is mechanical. Research has shown that carbonation reduces the resting pressure of the lower esophageal sphincter (the valve that keeps stomach acid from rising) by 30% to 50%. That reduction lasts around 20 minutes after drinking. This applies to all carbonated drinks: soda, sparkling water, seltzer, beer, and champagne. Even “healthy” sparkling waters with no sugar or caffeine still introduce carbonation that weakens that valve.
Coffee and caffeinated tea both increase stomach acid production and can relax the esophageal sphincter. If you can’t give up coffee entirely, cold brew tends to be less acidic than hot-brewed coffee, and drinking it with a splash of almond milk can help buffer the acidity. Limit yourself to one cup and avoid drinking it on an empty stomach.
Alcohol is a triple threat: it increases acid production, relaxes the esophageal sphincter, and irritates the lining of the esophagus directly. Red wine and cocktails with citrus mixers tend to be the worst, but all alcohol carries some risk for reflux.
Peppermint tea deserves a special mention because it seems like it should help. It’s herbal, it’s caffeine-free, and peppermint is associated with digestive relief. But peppermint works by relaxing smooth muscle, including the muscle of the lower esophageal sphincter. That relaxation is exactly what allows acid to escape upward. If you have reflux, peppermint tea is likely to make it worse despite its reputation.
Timing and Temperature
When you drink matters almost as much as what you drink. Large volumes of any liquid during a meal increase gastric distension, which is the stretching of your stomach that puts pressure on the esophageal valve. A better approach is to take small sips during meals and do most of your hydrating between meals.
Drinking anything within two to three hours of lying down is risky if you’re prone to nighttime reflux. Gravity helps keep acid in your stomach while you’re upright, but once you recline, even a mildly full stomach can send acid toward your throat. Finishing your last drink of the evening well before bedtime gives your stomach time to empty.
Temperature is a smaller factor, but very hot drinks can irritate an already inflamed esophagus. Room temperature or slightly warm beverages are gentler. Ice-cold drinks are fine for most people, though some find they cause mild stomach cramping that increases discomfort.
