Plain water is the safest, most effective drink for heartburn relief. It dilutes stomach acid, washes acid back down from the esophagus, and won’t trigger further irritation. But beyond plain water, several other beverages can help, and a few popular ones will make things worse.
Water and Alkaline Water
Room-temperature or cool water works well for mild heartburn. It physically rinses acid off the esophageal lining and dilutes the contents of your stomach. Sip it slowly rather than gulping a large amount at once, since filling your stomach quickly can push acid upward.
Alkaline water with a pH of 8.8 offers an extra advantage. At that pH, it permanently deactivates pepsin, the digestive enzyme that damages esophageal tissue when it refluxes up from the stomach. Pepsin becomes active below a pH of 4.6, which is the range found in most bottled and canned beverages. Alkaline water also has roughly eight times the buffering capacity of regular bottled water, meaning it takes significantly more acid to bring it back down into the danger zone. You can find naturally alkaline or ionized water at most grocery stores.
Ginger Tea
Ginger supports faster gastric emptying, the process of moving food from your stomach into your small intestine. Once food clears the stomach, acid production drops, which reduces the chance of acid splashing back up into your esophagus. A simple ginger tea made by steeping a few thin slices of fresh ginger root in hot water for five to ten minutes is a gentle option for occasional heartburn. Keep the amount small. Too much ginger can irritate the stomach lining and cause the opposite of what you’re going for.
Low-Acid Juices and Smoothies
Not all juices are created equal when it comes to heartburn. Citrus juice and tomato juice are highly acidic and will aggravate symptoms. But certain vegetable juices sit closer to neutral on the pH scale and are far less likely to cause problems. Carrot juice ranges from 5.88 to 6.40, celery juice from 5.70 to 6.00, and cucumber juice from 5.12 to 5.78. None of these are alkaline, but they’re mild enough that most people tolerate them well.
Smoothies made with banana, melon, or spinach blended with a non-dairy milk like oat or almond milk are another solid choice. The key is avoiding citrus fruits, chocolate, and high-fat ingredients like coconut cream, all of which can trigger reflux.
Aloe Vera Juice
Aloe vera has a long folk-medicine reputation for soothing the digestive tract, and there’s some clinical support behind it. A randomized controlled trial tested aloe vera syrup at 10 mL per day (about two teaspoons) over four weeks in people with gastroesophageal reflux disease. The results showed it was effective at reducing common symptoms like heartburn and regurgitation. If you try it, look for purified, decolorized aloe vera juice made for internal use. Whole-leaf aloe products can contain compounds with a strong laxative effect.
Baking Soda in Water
Dissolving half a teaspoon of baking soda in a glass of cold water creates a fast-acting antacid. It neutralizes stomach acid almost immediately, and many people feel relief within minutes. This is a reasonable option for occasional, breakthrough heartburn.
There are real limits, though. Baking soda is high in sodium, so it’s not appropriate if you’re watching your salt intake. Don’t take it within one to two hours of other medications, because it can interfere with absorption. Avoid combining it with large amounts of milk or dairy. And don’t use it for more than two weeks straight. If your heartburn keeps returning that often, the underlying cause needs attention, not just the symptom.
What to Avoid Drinking
Carbonated beverages are one of the worst choices during a heartburn episode. The carbon dioxide gas distends your stomach, and research shows this causes a sustained 30 to 50 percent reduction in the strength of the muscular valve between your esophagus and stomach. That valve, called the lower esophageal sphincter, is supposed to keep acid where it belongs. In over 60 percent of study participants, carbonation weakened the valve enough to reach levels normally considered diagnostic of sphincter incompetence. Plain tap water, by contrast, caused no reduction at all. This applies to sparkling water, soda, seltzer, and beer alike.
Coffee and caffeinated tea can also worsen reflux by relaxing that same valve and increasing acid production. If you don’t want to give up coffee entirely, cold brew tends to be less acidic than hot-brewed coffee, and drinking it with food rather than on an empty stomach helps.
Peppermint tea is a tricky one. It’s often recommended for digestive discomfort, but peppermint relaxes the smooth muscle in the lower esophagus. For someone with heartburn or GERD, that relaxation opens the door for acid to escape upward. If peppermint tea consistently makes your symptoms worse, that’s why.
Alcohol, particularly wine and spirits, is another common trigger. It increases stomach acid production and weakens the esophageal sphincter simultaneously.
When and How You Drink Matters
The timing and volume of what you drink can matter as much as what’s in the glass. Drinking large amounts of any liquid with meals overfills the stomach and creates pressure that pushes acid upward. Sipping smaller amounts throughout the day is a better strategy.
Nighttime heartburn is especially disruptive, and fluid timing plays a role. Limit how much you drink in the hour or two before bed. Stay hydrated earlier in the day instead. If you do need a sip before sleep, a small amount of plain or alkaline water is the least likely to cause problems. Elevating the head of your bed by a few inches also helps gravity keep acid in the stomach overnight.
