Plain water is the single best beverage for acid reflux, and several other drinks can help too: herbal teas, plant-based milks, low-acid vegetable juices, and alkaline water. Just as important as knowing what to reach for is knowing what to avoid, since coffee, alcohol, citrus juice, and carbonated drinks can all make symptoms worse.
Water: The Simplest Choice
Still water is the safest, most effective drink for managing reflux. It temporarily raises stomach pH, diluting the acid that splashes into your esophagus, and helps wash residual acid back down into the stomach. Small sips work better than gulping a full glass, especially during meals. Large volumes of any liquid expand the stomach and put pressure on the valve at the top (the lower esophageal sphincter), which is exactly the mechanism that triggers reflux in the first place.
Between meals, drink freely. With meals, keep it moderate. That simple timing adjustment can make a noticeable difference.
Herbal Teas That Soothe Symptoms
Chamomile, ginger, and turmeric teas are among the most popular home remedies for reflux, and there’s reason behind the reputation. All three contain anti-inflammatory and antioxidant compounds. Chamomile in particular may help relieve GERD symptoms when you drink it after meals or before bedtime, in part because it can calm irritation along the esophageal lining.
Ginger tea supports digestion by encouraging the stomach to empty faster, which means less acid sitting around to creep upward. Brew it from fresh ginger slices rather than sugary commercial ginger drinks, which can introduce other triggers. One thing to watch: peppermint tea, despite its reputation as a digestive aid, relaxes the esophageal sphincter and tends to make reflux worse. The American College of Gastroenterology lists peppermint as a trigger to avoid.
Plant-Based Milks Over Whole Dairy
Full-fat cow’s milk can trigger acid reflux. The fat content relaxes the esophageal sphincter and stimulates additional acid production, which is the opposite of what you want. If you like milk, switching to a plant-based alternative often helps.
Almond milk is alkaline, so it can actively lower stomach acidity and ease symptoms. Soy milk is naturally lower in fat than cow’s milk, making it another solid option. Oat milk falls in a similar range. If you prefer dairy, skim or low-fat versions are a reasonable compromise, though plant milks generally perform better for people with frequent reflux. Choose unsweetened varieties when you can, since added sugar can slow digestion.
Alkaline Water
Bottled alkaline water typically has a pH between 8 and 9, compared to regular tap water’s neutral pH of around 7. That extra alkalinity may help neutralize acid on contact in the esophagus. Some people find it noticeably soothing during a flare-up. It’s not a treatment on its own, but as a replacement for acidic drinks throughout the day, it’s a reasonable swap. Avoid products with pH levels above 9, as those may cause digestive discomfort of their own.
Low-Acid Vegetable Juices
Not all juices are created equal when it comes to reflux. Citrus and tomato juice are highly acidic and directly irritate a damaged esophageal lining. But juices made from less acidic produce are far gentler. Good options include carrot juice, cabbage juice, cucumber juice, beet juice, spinach juice, and watermelon or pear juice. If you’re making your own, these can be combined freely without spiking acidity.
Aloe vera juice deserves a separate mention. It has a long history as a digestive soother, and many people with reflux find it helpful. A reasonable starting point is a small amount every other day to see how your body responds, gradually working up to a cup a day if it agrees with you. Drinking too much can cause cramping or diarrhea, so start conservatively.
Why Carbonation Makes Things Worse
Sparkling water might seem harmless, but carbonation is one of the more reliable reflux triggers. A manometry study of healthy volunteers found that drinking just 200 mL of a carbonated beverage (about 7 ounces) cut the pressure of the esophageal sphincter by more than half, dropping it from a baseline of around 40 mmHg to about 18.5 mmHg. That sphincter is your body’s main barrier against acid flowing upward, and when its pressure drops, reflux follows.
Even more striking, the frequency of spontaneous sphincter relaxations (the brief openings that allow acid to escape) jumped from essentially zero at baseline to a median of 10.5 episodes after the carbonated drink. Plain water barely moved that number. This applies to all carbonated beverages: soda, sparkling water, seltzer, and beer. If reflux is a regular problem for you, flat drinks are the way to go.
Drinks to Avoid
The American College of Gastroenterology identifies several beverage categories as common triggers:
- Coffee and caffeinated drinks. Caffeine relaxes the esophageal sphincter and stimulates acid production. Decaf coffee is somewhat better but still mildly acidic.
- Alcohol. All types contribute to reflux. Alcohol both relaxes the sphincter and irritates the esophageal lining directly.
- Citrus juice. Orange, grapefruit, and lemon juice are highly acidic and irritate tissue that’s already inflamed.
- Tomato juice. Similarly acidic and a well-established trigger.
- Carbonated beverages. As described above, the gas itself is the problem regardless of the drink’s other ingredients.
- Chocolate drinks. Hot chocolate and chocolate milk contain compounds that relax the sphincter.
How You Drink Matters Too
Beyond choosing the right beverages, how and when you drink them influences symptoms. During meals, take small sips rather than draining a full glass. Large fluid volumes expand the stomach the same way a big meal does, increasing pressure against the sphincter. Between meals is the best time to hydrate more generously.
Avoid drinking anything in the two to three hours before lying down. Gravity helps keep stomach contents where they belong, and removing that advantage while your stomach is still processing liquid is a common reason for nighttime reflux. If you want a calming chamomile tea before bed, keep it to a small cup and give yourself at least 30 minutes upright before you sleep.
