Water is the single best thing to drink when you have acid reflux. It dilutes stomach acid, helps flush irritants out of the esophagus, and won’t trigger symptoms the way most flavored beverages can. But plain water isn’t your only option. Several other drinks can soothe symptoms or even help neutralize the acid causing your discomfort.
Why Water Works So Well
Drinking water throughout the day helps dilute stomach acid and rinse away any acid that has splashed up into your esophagus. It has a neutral pH, produces no gas, and contains nothing that relaxes the muscular valve between your stomach and esophagus (the valve that, when it loosens, lets acid escape upward).
Room temperature or slightly warm water tends to be the gentlest choice. Very hot beverages can irritate an already inflamed esophagus, while ice-cold water bothers some people, though evidence on temperature is limited. If you find cold water comfortable, there’s no strong reason to avoid it.
One practical tip: try sipping water between meals rather than drinking large amounts with food. A stomach that’s overly full is more likely to push its contents back up. If drinking with meals leaves you bloated or worsens your reflux, shifting your water intake to between meals can make a noticeable difference.
Alkaline Water: Worth Considering
Alkaline water with a pH of 8.8 has shown a specific benefit that regular water doesn’t offer. It permanently deactivates pepsin, the digestive enzyme that damages your esophagus and throat when it travels upward with refluxed acid. Pepsin becomes active at a pH below 4.6, which is the acidity level found in nearly all bottled and canned beverages. Alkaline water not only raises the pH above that threshold but also has roughly eight times the buffering capacity of standard bottled water, meaning it resists becoming acidic again more effectively.
This doesn’t mean you need to replace all your water with alkaline varieties. But keeping some on hand for moments when symptoms flare could provide faster relief than tap water alone.
Herbal Teas That Calm Symptoms
Caffeine-free herbal teas are among the best warm beverages for acid reflux. Three varieties stand out:
- Ginger tea has been used as a folk remedy for heartburn for centuries. Ginger root aids digestion and can help settle the stomach, making it a good choice after meals.
- Chamomile tea has a soothing effect on the digestive tract and may help reduce the inflammation that repeated acid exposure causes.
- Licorice root tea works differently from the other two. It increases the mucous coating on the esophageal lining, which helps the tissue resist irritation from stomach acid. Look for deglycyrrhizinated (DGL) licorice products if you plan to drink it regularly, since standard licorice in large amounts can raise blood pressure.
The key word with all of these is “herbal.” Standard black tea and green tea contain caffeine, which can loosen the valve at the top of your stomach and make reflux worse.
Plant-Based Milks and Low-Fat Dairy
Milk has a complicated reputation when it comes to heartburn. It feels soothing going down, but high-fat dairy can relax the valve that keeps acid in your stomach, making reflux more likely after the initial relief fades. Whole milk, with about 8 grams of fat per cup, is a common trigger. Goat’s milk is even fattier at around 10 grams per cup, so it’s not the upgrade some people hope for.
Skim milk is a better option if you prefer cow’s milk. But plant-based alternatives may be the best choice overall. Almond milk has a pH around 8.4, making it naturally alkaline, which could help neutralize stomach acid. Oat milk and rice milk are also gentle on the stomach and low in fat. Coconut water is another good pick: it’s hydrating, low in acidity, and often recommended as one of the fastest options for calming active reflux symptoms.
Low-Acid Fruit Juices
Most fruit juices are too acidic for people with reflux. Orange juice, grapefruit juice, and lemonade all sit well below a pH of 4, which is firmly in the danger zone. But a few fruit juices have higher pH levels and are less likely to trigger symptoms:
- Watermelon juice: pH around 5.2 to 5.6, the least acidic common fruit juice
- Mango juice: pH around 4.5 to 5.0
- Pear juice: pH around 4.0 to 4.5
- Peach juice: pH around 3.8 to 4.2
Watermelon and mango juice are your safest bets. Pear and peach juice are borderline, so your tolerance will depend on how sensitive your reflux is. Apple juice, despite being non-citrus, has a pH of only 3.5 to 4.0, which puts it on the more acidic end. If you want fruit juice, diluting it with water can lower the acid concentration and make it easier on your esophagus.
Aloe Vera Juice
Aloe vera juice is frequently recommended alongside ginger tea and coconut water as one of the most effective options for quickly calming active reflux symptoms. It has mild anti-inflammatory properties that can help soothe irritated tissue in the esophagus. Look for versions labeled for internal use and without added sugars or citric acid, which would defeat the purpose.
Drinks That Make Reflux Worse
Knowing what to avoid matters just as much as knowing what to reach for. A few categories of beverages are reliably problematic.
Carbonated Drinks
Carbonation is one of the worst offenders. The gas from carbonated beverages causes your stomach to expand, which weakens the valve at the top of your stomach by 30 to 50% for a sustained period of about 20 minutes. In over 60% of cases studied, carbonation weakened the valve enough to reach a level that would normally be diagnosed as incompetent. This applies to sparkling water, soda, seltzer, and any other fizzy drink.
Coffee and Caffeinated Tea
Caffeine relaxes the same valve that carbonation weakens, and coffee is also naturally acidic. If you’re not willing to give it up entirely, cold brew tends to be less acidic than hot-brewed coffee, and limiting yourself to one cup earlier in the day (rather than on an empty stomach or close to bedtime) can reduce the impact.
Alcohol
Alcohol damages the esophageal lining directly, and the harm is concentration-dependent. At the ethanol levels found in beer (around 5%) and wine (around 10%), changes to the esophageal tissue begin within 10 minutes of exposure. At 10% ethanol, the damage becomes difficult for the tissue to reverse even after the exposure stops. Beer and wine also stimulate extra stomach acid production, making refluxed material more corrosive. When alcohol and acid hit the esophagus together, the tissue damage is significantly worse than either one alone.
Research links regular beer consumption in early adulthood to more than double the risk of esophageal inflammation. Binge drinking and high liquor intake (more than about four and a half drinks per week) each roughly double the risk of reflux-related esophagitis as well. If you drink socially, keeping it minimal and avoiding lying down afterward are the most practical harm-reduction steps.
Citrus Juice and Tomato-Based Drinks
Orange juice, grapefruit juice, lemonade, and tomato juice all have pH levels low enough to activate pepsin and directly irritate an inflamed esophagus. These are worth eliminating entirely during flare-ups.
A Simple Approach
Your daily default should be plain water, sipped regularly between meals. For variety or symptom relief, rotate in herbal teas (ginger, chamomile, or licorice root), coconut water, almond milk, or aloe vera juice. Keep alkaline water available for flare-ups. Avoid carbonation, caffeine, alcohol, and citrus juices. Most people with acid reflux find that these changes alone produce a noticeable reduction in how often and how intensely symptoms hit.
