Plain water is the single best drink for acid reflux. It dilutes stomach acid, clears acid from the esophagus, and has a neutral pH that won’t trigger symptoms. But beyond plain water, several other beverages can actively soothe reflux, and a few popular “healthy” drinks can make it worse.
Why Water Works So Well
Water does three things at once when reflux flares up. It washes acid back down into the stomach, dilutes the acid that’s already there, and helps clear an enzyme called pepsin from your esophageal lining. Pepsin is a protein-digesting enzyme that travels up from the stomach during a reflux episode and clings to the delicate tissue in your throat and esophagus. Even after the burning sensation fades, pepsin can remain active and continue irritating those tissues. Water helps flush it away.
For most people, room-temperature or slightly warm water is gentler than ice-cold water, which can sometimes cause the stomach muscles to contract.
Alkaline Water and Pepsin
Alkaline water with a pH of 8.8 or higher can permanently deactivate pepsin, which regular water (pH around 7) cannot do on its own. Research from Harvard-affiliated investigators found that water at this pH level denatures pepsin in esophageal tissue, essentially neutralizing the enzyme so it can no longer cause damage. This makes alkaline water particularly useful if you experience symptoms like a chronic sore throat, hoarseness, or a sensation of something stuck in your throat, all of which point to pepsin lingering outside the stomach.
You can find bottled alkaline water at most grocery stores. Some people add a small amount of baking soda to regular water to raise the pH, though this adds sodium, which may be a concern if you’re watching your salt intake.
Plant-Based Milks and Low-Fat Dairy
Non-dairy milks like almond, oat, and soy milk are naturally low in fat and tend to have a slightly alkaline or neutral pH, making them good options for reflux. They also coat the esophagus briefly, which can ease that raw, burning feeling. Almond milk is a particularly popular choice because it’s alkaline-leaning and light on the stomach.
Regular cow’s milk is more complicated. While it can feel soothing going down, full-fat milk stimulates more stomach acid production once it’s digested. If you prefer dairy, stick to skim or 1% milk. The protein in milk does provide a temporary buffering effect, but the fat content in whole milk can relax the valve between your esophagus and stomach, making reflux worse within an hour or two.
Ginger Tea
Ginger has natural anti-inflammatory properties and has been used for centuries to calm nausea and digestive discomfort. Brewing fresh ginger slices in hot water creates a mildly alkaline tea that can reduce the sensation of acid creeping up. It also helps move food through the stomach faster, which means less opportunity for acid to splash upward.
Keep it simple: a few thin slices of fresh ginger steeped in hot water for 10 to 15 minutes. Avoid commercial ginger ales, which are carbonated, high in sugar, and typically contain very little actual ginger.
Aloe Vera Juice
Aloe vera juice has shown modest benefits for reflux symptoms in clinical studies. Patients given 10 milliliters of aloe vera gel syrup twice daily experienced symptom relief comparable to standard acid-reducing medications, with no reported side effects. Aloe vera appears to reduce inflammation in the esophageal lining and may help with tissue healing.
If you try it, look for products labeled “decolorized” or “purified,” which have had the latex compounds removed. The latex layer of the aloe plant acts as a laxative and can cause cramping. Start with a small amount to see how your body responds.
Coconut Water
Coconut water is naturally alkaline and rich in potassium, with roughly 600 milligrams per cup (more than a medium banana). It’s not acidic, not carbonated, and not fatty, which checks every box for a reflux-friendly drink. Some people find it particularly soothing after meals. Choose plain, unsweetened varieties. Flavored coconut waters often contain added sugars or citric acid that can undo the benefits.
Drinks That Make Reflux Worse
Knowing what to avoid matters just as much as knowing what helps. The American College of Gastroenterology specifically identifies several beverages as reflux triggers:
- Coffee and caffeinated drinks relax the lower esophageal sphincter, the muscular valve that keeps stomach acid where it belongs. This includes regular tea, energy drinks, and caffeinated sodas. Decaf coffee is slightly better but still acidic enough to irritate damaged tissue.
- Alcohol contributes to reflux through multiple pathways. It relaxes the esophageal sphincter, increases acid production, and slows stomach emptying. Beer and wine tend to be worse than spirits because of their higher volume and carbonation (in beer’s case), but all alcohol is a problem.
- Citrus juices like orange juice, grapefruit juice, and lemonade are highly acidic and can directly irritate an already inflamed esophagus. Tomato juice falls in this category too.
- Carbonated beverages of any kind expand the stomach with gas, which pushes acid upward. Even sparkling water, despite having no sugar or caffeine, can trigger symptoms in people with frequent reflux.
- Chocolate-based drinks like hot cocoa contain compounds that relax the esophageal sphincter and stimulate acid production.
What About Fermented Drinks?
Kefir and kombucha are often recommended for gut health because of their probiotic content, but they’re a mixed bag for reflux. Kombucha is acidic (it contains acetic acid, the same acid found in vinegar), carbonated, and high in compounds called FODMAPs that can cause bloating and stomach upset. The fizz alone is enough to trigger reflux in many people. Kefir is a better option since it’s not carbonated, and it has a long history of use for digestive issues including stomach ulcers. If you want to try a fermented drink, plain, unsweetened kefir is the safer choice. Start with a small serving to gauge your reaction.
Timing and Temperature Tips
What you drink matters, but when and how you drink it also makes a difference. Sipping water throughout the day keeps your esophagus clear and your stomach acid diluted. Drinking large volumes at once, especially during meals, can overfill the stomach and increase reflux pressure. A practical approach is to drink most of your fluids between meals rather than with them.
After eating, wait at least 20 to 30 minutes before lying down, and keep a glass of water nearby for nighttime symptoms. If reflux tends to hit at night, a few sips of room-temperature water or alkaline water before bed can help neutralize any acid that creeps up while you sleep.
