Plain water is the simplest and most reliable drink for acid reflux, but it’s far from the only option. Several beverages can help neutralize stomach acid, speed digestion, or soothe an irritated esophagus. Just as important as what you drink is how much you drink at once and what you avoid.
Water and Alkaline Water
Regular water dilutes stomach acid and helps clear it from the esophagus. Sipping water throughout the day, especially between meals, is one of the easiest ways to reduce reflux symptoms. If you want something with a bit more neutralizing power, alkaline water with a pH of 8.8 has been shown to permanently deactivate pepsin, the stomach enzyme responsible for much of the damage reflux causes to the throat and esophagus. A lab study published in the Annals of Otology, Rhinology, and Laryngology found that regular drinking water doesn’t have this effect, because pepsin stays stable at neutral pH and can be reactivated by acid. Alkaline water at 8.8 also buffered hydrochloric acid more effectively than conventional water.
That said, alkaline water isn’t a replacement for other treatments if your reflux is frequent or severe. It works best as a complement to broader dietary changes.
Ginger Tea
Ginger supports faster gastric emptying, meaning food moves from your stomach into the small intestine more quickly. Once food leaves the stomach, acid production drops, which reduces the chance of acid washing back up into the esophagus. To make ginger tea, peel and slice or grate fresh ginger root, then steep it in boiling water for about 15 minutes. You can also add it raw to hot water for a milder version. Stick to small amounts, since too much ginger can sometimes cause its own stomach discomfort.
Low-Fat and Plant-Based Milks
Milk coats the esophagus and can provide temporary relief, but fat content matters. Full-fat dairy relaxes the muscle between your esophagus and stomach, slowing digestion and making reflux worse. Johns Hopkins Medicine specifically identifies high-fat foods as among the worst triggers for heartburn. If you reach for milk, choose skim or low-fat versions.
Plant milks like unsweetened almond milk are popular alternatives. They tend to be lower in fat and are naturally less acidic than cow’s milk. Almond milk in particular has a mildly alkaline profile, which is why it shows up as a base ingredient in many reflux-friendly smoothie recipes. Soy milk is another option, though some people find it harder to digest. Coconut milk works well in smoothies but can be higher in fat depending on the variety, so look for “light” versions.
Coconut Water
Unsweetened coconut water is naturally low in acid and rich in potassium, an electrolyte that helps promote pH balance in the body. It’s light enough that it won’t stretch the stomach the way a large glass of juice might. Make sure to choose plain, unsweetened varieties. Flavored coconut waters often contain added sugars or citric acid, both of which can trigger symptoms.
Reflux-Friendly Smoothies
Smoothies can be a good option as long as you choose your ingredients carefully. The best bases are unsweetened almond milk, coconut milk, or coconut water. For fruit, stick with low-acid options: bananas, mangoes, melons, and blueberries all work well. Adding oatmeal or carrots gives extra body without adding acidity. A banana-blueberry smoothie with almond milk, for example, is filling without provoking symptoms.
What to leave out: citrus fruits, tomatoes, chocolate, spices, and anything caffeinated. Very cold ingredients can also irritate the esophagus in some people, so consider letting frozen fruit soften slightly before blending.
Drinks to Avoid
The American College of Gastroenterology recommends avoiding coffee, alcohol, chocolate-based drinks, and citrus or tomato juice. Coffee and other caffeinated beverages relax the lower esophageal sphincter, making it easier for acid to escape upward. Alcohol does the same and also irritates the esophageal lining directly. Citrus and tomato juices are acidic enough to cause pain on contact if the esophagus is already inflamed. Peppermint tea, despite its reputation as a stomach soother, also relaxes that sphincter and can worsen reflux.
Carbonated drinks are another common trigger. The gas they produce increases pressure inside the stomach, which can force acid upward.
How Much You Drink Matters
Even the most reflux-friendly drink can cause problems if you consume too much at once. A study in the Journal of Gastroenterology and Hepatology compared what happened when people with reflux drank 600 mL (about 20 ounces) at a time versus 300 mL (about 10 ounces) in more frequent sittings. The larger volume produced significantly more reflux episodes (17 versus 10 on average) and nearly doubled total acid exposure time in the esophagus. The larger meals also stretched the upper portion of the stomach more, which directly increases pressure on the valve that keeps acid contained.
The practical takeaway: keep drinks to about 10 ounces or less per sitting, and sip rather than gulp. If you’re thirsty, drink between meals rather than with a large plate of food, since the combined volume of food and liquid amplifies the problem. Staying upright for at least 30 minutes after drinking also helps gravity keep things moving in the right direction.
