Water is the safest and simplest drink for acid reflux, but it’s far from your only option. Several other beverages can soothe symptoms or at least avoid making them worse, while a handful of common drinks are worth limiting or cutting out. The key is understanding which drinks relax the muscular valve between your stomach and esophagus, and which ones leave it alone.
Why Your Drink Choice Matters
At the bottom of your esophagus sits a ring of muscle called the lower esophageal sphincter (LES). When it’s working properly, it opens to let food into your stomach and then closes tightly. Acid reflux happens when that valve relaxes at the wrong time or stays too weak to hold stomach contents down. Certain beverages directly weaken this valve, increase pressure inside the stomach, or add acid to an already irritated esophagus. Others are neutral or even mildly protective.
Plain Water and Alkaline Water
Plain water doesn’t reduce sphincter pressure at all, making it the baseline safe choice. It dilutes stomach acid and helps move food through your digestive system. Sipping water throughout the day, rather than gulping large amounts at meals, keeps your stomach from overfilling.
Alkaline water with a pH of 8.8 goes a step further. A study published in the Annals of Otology, Rhinology, and Laryngology found that water at this pH permanently inactivates pepsin, the stomach enzyme that damages esophageal tissue when it splashes upward. Regular tap water doesn’t do this. If your reflux includes throat irritation, hoarseness, or a chronic cough (signs that pepsin is reaching your throat), alkaline water may offer an extra layer of protection. It’s not a replacement for other management strategies, but it’s a reasonable swap for your daily water.
Herbal Teas That Help
Ginger tea is one of the better-studied options. Ginger supports faster gastric emptying, meaning food moves out of your stomach and into the rest of your digestive tract more quickly. A stomach that empties efficiently produces less upward pressure on the LES. To make it, peel fresh ginger root, slice or grate it, and steep it in boiling water for about 15 minutes. Keep the portion modest, since very concentrated ginger can sometimes irritate the stomach lining on its own.
Chamomile tea has anti-inflammatory and antioxidant properties that may ease reflux symptoms tied to inflammation or stress. Drinking it after meals or before bedtime is a common approach. Direct clinical evidence specifically measuring its effect on reflux episodes is limited, but its gentle, caffeine-free profile makes it a low-risk choice. Licorice root tea (specifically the deglycyrrhizinated form) is another option some people find soothing, though you should look for products labeled “DGL” to avoid a compound in regular licorice that can raise blood pressure.
Non-Dairy Milk Alternatives
Full-fat dairy milk can be a mixed bag for reflux. While it temporarily coats the esophagus, the fat content can relax the LES and increase acid production over the following hour. Plant-based milks tend to be a better fit. Almond milk is alkaline-forming, meaning it doesn’t add acid load, and it’s naturally low in fat. Oat milk is another mild, low-acid option that most people tolerate well.
If you prefer cow’s milk, choosing skim or low-fat versions reduces the fat-related trigger while still giving you that soothing coating. Avoid flavored or sweetened varieties of any milk, since added sugars can slow digestion and increase reflux risk.
Coconut Water
Unsweetened coconut water is a solid option. It’s a natural source of electrolytes like potassium and promotes pH balance in the body. It’s not acidic, it’s not carbonated, and it’s not caffeinated, which checks every box for reflux safety. Look for brands without added sugar or fruit juice blends, since those additions can lower the pH and defeat the purpose.
Low-Acid Juices
Most fruit juices are too acidic for regular consumption if you have reflux. Orange juice, grapefruit juice, and lemonade all have a pH well below 4.0, putting them in the same acidity range as stomach acid itself. But not all juices are off the table. Carrot juice, watermelon juice, and pear juice tend to sit at a higher pH and are generally better tolerated. Aloe vera juice (in small amounts, specifically versions processed to remove laxative compounds) is another option some people use to calm irritation.
If you want fruit flavor, diluting a small amount of a milder juice with water can give you the taste without the acid concentration. Avoid drinking any juice on an empty stomach, where it hits the esophageal lining without a food buffer.
What to Limit or Avoid
Coffee and Caffeinated Drinks
Coffee weakens the lower esophageal sphincter whether it’s acidic or not. In one study, even coffee adjusted to a neutral pH of 7.0 still caused a significant drop in sphincter pressure. In people who already had reflux disease, acidic coffee dropped LES pressure from about 9 mmHg to 5.5 mmHg, pushing the valve into ranges considered functionally incompetent. This means decaf coffee and low-acid coffee brands may help slightly, but caffeine itself is only part of the problem. Other compounds in coffee also relax the valve.
Regular tea with caffeine (black tea, green tea) is generally less problematic than coffee but can still trigger symptoms in sensitive individuals. If you aren’t ready to give up caffeine entirely, try limiting yourself to one cup earlier in the day, drinking it with food, and noting whether your symptoms change.
Carbonated Beverages
Carbonation is a consistent reflux trigger. When carbonated drinks release gas in the stomach, they cause distension that directly weakens the LES. Research on healthy volunteers found that all carbonated beverages produced a sustained 30 to 50 percent reduction in sphincter pressure and length lasting at least 20 minutes. In 62 percent of cases, the reduction was severe enough to push the sphincter into a range normally diagnosed as incompetent. This applies to sparkling water, soda, seltzer, and kombucha alike. The bubbles are the problem, not just the sugar or caffeine.
Alcohol
Alcohol relaxes the LES, increases stomach acid production, and can directly irritate the esophageal lining. Wine and spirits tend to be the worst offenders, though beer combines alcohol with carbonation for a double hit. If you do drink occasionally, lower-alcohol options in smaller quantities, consumed with food, are less likely to cause a flare than drinking on an empty stomach.
Citrus Drinks and Tomato Juice
These are highly acidic and are among the most commonly reported triggers. Even if they don’t relax the LES mechanically, the acid itself irritates already-inflamed tissue. If your esophagus is actively irritated, acidic drinks can cause pain even when reflux events themselves are minimal.
Timing and Temperature Tips
What you drink matters, but when you drink it also plays a role. Stanford Health Care’s reflux protocol recommends not drinking anything right before sleep, since lying down with a full stomach (even if it’s just liquid) makes it easier for contents to flow back up. Finishing your last drink at least two to three hours before bed gives your stomach time to process the fluid.
During meals, small sips are better than large glasses. Flooding your stomach with liquid while eating increases volume and pressure. Between meals, steady hydration with water or herbal tea keeps things moving without overloading the system. Room temperature or warm drinks are often better tolerated than ice-cold beverages, which can slow digestion in some people, though this varies individually.
