Water is the single best thing you can drink with acid reflux. It’s neutral, calorie-free, and won’t irritate your esophagus. But plain water all day gets boring, and the good news is you have plenty of other options. The key is avoiding drinks that are highly acidic, high in fat, or carbonated, since all three can push stomach acid back up into your esophagus.
Why Some Drinks Trigger Reflux
The valve between your esophagus and stomach (called the lower esophageal sphincter) is supposed to stay closed after you swallow. Certain drinks relax that valve or increase pressure in your stomach, making it easier for acid to splash upward. High-fat beverages slow digestion and keep food sitting in your stomach longer, which raises the odds of reflux. Highly acidic drinks like orange juice (pH 3.3 to 4.2) and tomato juice (pH 4.1 to 4.6) add acid on top of whatever your stomach is already producing, which can worsen the burning sensation even if they don’t directly trigger the valve to open.
Herbal Teas That Soothe
Herbal teas are one of the most popular reflux-friendly alternatives to water, and a few have genuine digestive benefits. Chamomile tea can have a soothing effect on the digestive tract, and it’s naturally caffeine-free. Ginger tea has anti-inflammatory properties and has been used for centuries as a folk remedy for heartburn. It also helps with nausea, which sometimes accompanies reflux.
Licorice root tea is another option worth trying. Licorice can help increase the mucus coating of the esophageal lining, which may reduce the irritation caused by backflowing stomach acid. Other herbal teas like fennel, marshmallow root, and slippery elm have long folk traditions as digestive aids, though scientific evidence for their effectiveness is still limited. If you enjoy them and they don’t bother you, they’re perfectly safe choices.
One important note: peppermint tea, despite its reputation as a stomach soother, can actually relax the esophageal valve and make reflux worse. If peppermint triggers your symptoms, skip it.
The Best Milk Options
Milk has a complicated relationship with acid reflux. Whole milk and other full-fat dairy drinks can trigger symptoms because saturated fat slows stomach emptying. But low-fat or skim milk may actually help. The protein and calcium in milk can temporarily buffer stomach acid, and without the excess fat, it’s less likely to cause problems.
Plant-based milks are generally good alternatives. Almond milk, oat milk, soy milk, and cashew milk are all lower in fat than whole dairy milk and tend to be well tolerated. If you choose a flavored variety, watch out for added sugars, which can contribute to reflux in large amounts. Plain, unsweetened versions are your safest bet.
Juices to Choose and Avoid
Citrus juices are among the worst drinks for acid reflux. Apple juice, orange juice, grapefruit juice, and lemonade all fall in the pH 3 to 4 range, making them quite acidic. Tomato juice is similarly problematic.
If you want juice, look for low-acid options. Carrot juice, watermelon juice, and pear juice are gentler on the esophagus. Aloe vera juice (sold specifically for drinking) is another option some people find soothing. With any juice, smaller portions help. A full glass of even a mild juice fills your stomach more than sipping water, and that added volume can contribute to reflux on its own.
What About Coffee and Caffeine?
The conventional advice has always been to avoid coffee entirely if you have reflux. The logic is that caffeine relaxes the esophageal valve. But the actual research is more nuanced. Epidemiological studies on coffee and reflux disease have produced mixed results, and there isn’t strong enough evidence to support blanket caffeine avoidance for everyone with reflux.
In practice, this means coffee affects people differently. Some people can drink a cup in the morning with no issues, while others get heartburn from a few sips. If you want to keep coffee in your routine, try switching to a low-acid or cold-brew variety, keeping it to one cup, and avoiding it on an empty stomach. If that still causes symptoms, it’s worth cutting back. The same applies to regular black and green tea, which contain less caffeine than coffee but can still be a trigger for sensitive individuals.
Why Carbonation Is a Problem
Sparkling water, soda, and other carbonated drinks introduce gas into your stomach. That gas expands the stomach, increasing internal pressure. Studies have found that this gastric distension can cause the esophageal valve to relax temporarily, giving acid an opening to move upward. Some research has also shown that carbonated beverages reduce the resting pressure of the valve compared to non-carbonated drinks.
This doesn’t mean a sip of sparkling water will always cause a flare-up. But if you’re having frequent reflux episodes, carbonated drinks are one of the easier things to eliminate. Diet sodas and regular sodas are both problematic here, since the issue is the carbonation itself, not just the sugar or flavorings.
Alcohol and Reflux
Alcohol relaxes the esophageal valve and increases stomach acid production, making it a double trigger. Wine, beer, and spirits can all cause symptoms. Beer adds carbonation on top of the alcohol. Red wine is particularly acidic. If you choose to drink, smaller amounts with food tend to be less problematic than drinking on an empty stomach. Diluting spirits with a non-acidic, non-carbonated mixer (like water or a low-acid juice) is a better strategy than mixing with soda or citrus.
How You Drink Matters Too
What you drink is only part of the equation. How and when you drink also affects reflux. Drinking large volumes of any liquid in a short period fills your stomach rapidly, which increases the chance of acid pushing upward. Sipping slowly throughout a meal or between meals is gentler on your system.
There’s a common belief that drinking water during meals dilutes stomach acid and worsens digestion, but Mayo Clinic notes that water doesn’t cause problems with digestion or thin the fluids your body uses to break down food. A glass of water with your meal is fine and can actually help you feel full without extra calories. The more important factor is keeping your overall portion sizes reasonable, both food and liquid, so your stomach isn’t overly distended after eating.
Timing matters in another way too. Drinking anything, even water, right before lying down gives gravity less time to help keep stomach contents where they belong. Try to finish your last significant drink at least two to three hours before bed.
Quick Reference: Best and Worst Choices
- Best options: plain water, chamomile tea, ginger tea, licorice root tea, low-fat or skim milk, unsweetened almond or oat milk, coconut water, carrot juice
- Use caution: coffee, black tea, green tea, low-acid fruit juices, flavored plant milks
- Avoid or limit: orange juice, tomato juice, lemonade, soda, sparkling water, whole milk, alcohol, energy drinks
Everyone’s triggers are slightly different, so the most useful thing you can do is pay attention to how specific drinks affect you personally. Start with the safest options and reintroduce others one at a time. You may find that a morning coffee is fine but an evening glass of wine isn’t, or that cold brew works where regular coffee doesn’t. Your own pattern of reactions is more reliable than any general list.
