Plain water is the single best drink for acid reflux. It’s neutral in pH, doesn’t relax the valve between your esophagus and stomach, and helps dilute and clear acid that has already splashed upward. But water isn’t your only option. Several other beverages can soothe symptoms or at least avoid making them worse, while a few popular drinks will reliably make things worse.
Water and How to Drink It
Still water at room temperature or slightly warm is the safest choice during a flare-up. Cold water is fine too, though some people find very cold drinks briefly increase discomfort. The key habit is sipping rather than gulping. Drinking large volumes at once stretches the stomach, which can push acid upward.
Timing matters as much as what you drink. Sit upright for at least one to two hours after eating or drinking anything substantial. If you tend to get reflux at night, finish your last big glass of water well before lying down. Small sips with meals are better than draining a full glass, since excess fluid on top of food adds volume and pressure to the stomach.
Why Carbonation Makes Reflux Worse
Sparkling water, soda, seltzer, and any carbonated drink are worth avoiding. The carbon dioxide gas expands inside your stomach and forces the lower esophageal sphincter (the muscular ring that keeps acid out of your throat) to relax. Research published in the Journal of Gastrointestinal Surgery found that all carbonated beverages reduced the sphincter’s pressure by 30 to 50 percent, and that reduction lasted a full 20 minutes. That’s a wide-open door for acid to travel upward. Even “healthy” sparkling water causes the same effect, so the carbonation itself is the problem, not the sugar or flavoring.
Herbal Teas That Help (and One to Skip)
Chamomile tea and ginger tea are two of the most consistently recommended options. Chamomile has mild anti-inflammatory properties that can calm irritated tissue in the esophagus and stomach lining. Ginger has a long track record of easing nausea and settling the stomach, and it does not relax the esophageal sphincter the way some other herbs do. Licorice root tea, specifically the deglycyrrhizinated form, is another option that some people find soothing.
Peppermint tea is the one to skip. While peppermint is a classic remedy for general stomach upset, it relaxes the esophageal sphincter and can worsen acid reflux. If you enjoy mint flavor, this is one situation where it works against you.
Brew any herbal tea at a moderate temperature and avoid adding citrus. A small amount of honey is fine if you want sweetness.
Aloe Vera Juice
Aloe vera juice has some genuine evidence behind it, not just folklore. In a randomized controlled trial of 79 people with GERD, participants who drank a small daily dose of aloe vera syrup saw significant drops in their most common symptoms over four weeks. Heartburn dropped from 100 percent of participants at baseline to about 29 percent by week four. Flatulence went from 100 percent to roughly 12 percent. Food regurgitation fell to 10 percent.
If you want to try it, look for aloe vera juice labeled for internal use and free of aloin, the compound in raw aloe that acts as a harsh laxative. Start with a small amount (a few ounces before meals) to see how your body responds.
Milk: Helpful or Harmful?
Milk feels soothing going down because its fat coats the esophagus temporarily. But that relief is short-lived. Milk stimulates your stomach to produce more acid, which can intensify symptoms within the hour. Fat content is the main factor. Whole milk and 2% milk are high enough in fat to slow stomach emptying and increase pressure against the sphincter. Skim milk is a better option if you want dairy, since removing the fat eliminates most of the rebound effect.
Plant-based milks tend to be friendlier for reflux. Almond milk is naturally alkaline-forming and low in fat. Oat milk is another mild, low-acid option. Avoid coconut milk, which is high in fat, and flavored varieties loaded with sugar or chocolate.
Juices: Choose Low-Acid Options
Citrus juice is one of the worst drinks for reflux. Orange juice has a pH between 3.3 and 4.2, making it highly acidic and a direct irritant to an already inflamed esophagus. Grapefruit, lemon, and tomato juice fall in a similar range.
Safer alternatives are juices made from less acidic fruits and vegetables. Watermelon has a pH between 5.2 and 5.6, making it considerably gentler. Carrots land between 5.9 and 6.4, close to neutral. Pear juice is a bit more acidic (pH 3.5 to 4.6) but still tolerable for many people when diluted with water. If you want fruit flavor without the burn, blending watermelon or cantaloupe into a smoothie with a splash of almond milk is a practical option.
Coffee and What to Do About It
Coffee is acidic, and caffeine relaxes the lower esophageal sphincter. That’s a double hit. If you’re not willing to give it up entirely, a few adjustments can reduce the damage. Cold brew is lower in acid than hot-brewed coffee. Low-acid coffee brands use beans roasted or processed to reduce acidity. Drinking coffee with food rather than on an empty stomach also helps buffer the acid. And keeping it to one cup rather than three makes a noticeable difference for most people.
Caffeinated tea (black or green) is milder than coffee but still contains enough caffeine to be a trigger in large amounts. If you drink it, keep the volume moderate.
Alcohol and Reflux
Alcohol relaxes the esophageal sphincter, increases stomach acid production, and can directly irritate the esophageal lining. Red wine and beer are common triggers. Spirits mixed with citrus or carbonated mixers combine multiple problems in one glass. If you drink occasionally, small amounts of a non-carbonated, low-acid option (like a small glass of white wine) are less likely to cause a flare than beer or cocktails, but no alcoholic drink is truly reflux-friendly.
A Quick-Reference List
- Best choices: still water, chamomile tea, ginger tea, almond milk, oat milk, aloe vera juice, watermelon juice, carrot juice
- Use with caution: skim milk, cold brew coffee, low-acid coffee, diluted pear juice, small amounts of non-citrus smoothies
- Avoid or limit: orange juice, tomato juice, whole milk, chocolate milk, peppermint tea, all carbonated drinks, alcohol, regular hot coffee
Habits That Matter as Much as the Drink
What you drink is only part of the equation. How and when you drink it shapes your symptoms just as much. Sip slowly rather than chugging. Stay upright for one to two hours after eating or drinking. Avoid large volumes of any liquid right before bed. If you eat a heavy meal, wait before drinking a full glass of anything, since added volume in a full stomach increases the chance of reflux.
Over time, most people with acid reflux develop a personal trigger list. The drinks above are general patterns, but your body may tolerate some “caution” items just fine while reacting strongly to something unexpected. Paying attention to what you drank in the hour before a flare-up is the most reliable way to narrow down your own triggers.
