Water is the single best drink for acid reflux, and a few other options can also ease symptoms or at least avoid making them worse. The key is choosing beverages that are low in acid, low in fat, and free of common triggers like caffeine, alcohol, and carbonation. Here’s what actually helps and why.
Water and Alkaline Water
Plain water is the safest choice. It dilutes stomach acid, helps clear acid from the esophagus, and has zero risk of triggering symptoms. Sipping water throughout the day keeps you hydrated without adding any irritants.
Alkaline water, which has a pH of 8.8 or higher, may offer a small extra benefit. At that pH level, it can help neutralize pepsin, the digestive enzyme that damages the esophageal lining when stomach contents splash upward. Regular tap water typically has a pH around 7, so it won’t inactivate pepsin the same way. Alkaline water isn’t a replacement for other treatment, but if you’re reaching for a bottle at the store, it’s a reasonable upgrade.
Low-Fat and Plant-Based Milks
Milk can feel soothing going down, but the type matters. Fat relaxes the muscular valve between your esophagus and stomach, which is exactly the valve you need working well to keep acid where it belongs. Skim milk and 1% milk are the recommended choices. Whole milk, 2% milk, cream, and chocolate milk are all associated with worsening symptoms.
Unsweetened almond milk and coconut milk are popular alternatives and work well as neutral, low-acid beverages. They also serve as useful bases for smoothies (more on that below). Avoid flavored or sweetened versions, which can contain added ingredients that irritate the stomach.
Herbal Teas That May Help
Not all teas are equal here. Caffeinated teas and coffee are common reflux triggers. But certain herbal teas can have a calming effect on the digestive tract.
- Chamomile tea has a soothing effect on the digestive tract and is one of the most commonly recommended options for occasional heartburn.
- Ginger tea has natural anti-inflammatory properties and has long been used to settle nausea and stomach discomfort. Stick to mild concentrations, since very strong ginger can sometimes irritate sensitive stomachs.
- Licorice root tea is thought to increase the mucous coating of the esophageal lining, helping it resist the irritating effects of stomach acid. Look for deglycyrrhizinated (DGL) varieties, which have a compound removed that can raise blood pressure with long-term use.
Other herbal options like fennel, marshmallow root, and papaya tea are sometimes mentioned in home remedy guides, but there’s little scientific evidence confirming they work for reflux specifically. They’re unlikely to cause harm, but don’t expect reliable results.
Coconut Water
Coconut water is naturally alkaline, a good source of potassium and other electrolytes, and promotes pH balance in the body. It’s a mild, low-acid option that many people with reflux tolerate well. Choose plain, unsweetened coconut water. Some brands add sugar or fruit juice concentrates that increase acidity.
Smoothies Built the Right Way
A well-constructed smoothie can double as a reflux-friendly meal. The trick is choosing the right base and keeping ingredients high in fiber and healthy fats while avoiding citrus, tomato, and other acidic additions.
For liquid bases, unsweetened almond milk, coconut milk, and coconut water all work well. From there, build with ingredients that doctors recommend for people managing reflux: bananas, melons, carrots, avocados, oats, and seeds like chia or flaxseed. The fiber in oats and seeds helps absorb stomach acid, and healthy fats from avocado and nut butters are less likely to trigger symptoms than the saturated fat in dairy cream or whole milk.
A few combinations that tend to work well: banana and blueberry with almond milk and chia seeds, mango with coconut milk and rolled oats, or melon blended with coconut water and a teaspoon of flaxseeds. Avoid adding citrus fruits, pineapple, or mint, all of which can aggravate reflux.
Cabbage Juice
This one sounds unusual, but cabbage juice has a long history in folk medicine for digestive issues. Animal research has shown that cabbage extract increases the pH of gastric juice (making it less acidic), reduces overall stomach acid volume, and appears to shrink ulcers. Researchers attribute some of this effect to a compound sometimes called “vitamin U,” which may lower inflammation and support healing in the stomach and esophageal lining. Carrot juice is another mild, low-acid vegetable juice worth trying.
Neither is a proven treatment on its own, but swapping an acidic beverage for a glass of fresh vegetable juice is a practical, low-risk change.
What to Avoid Drinking
Knowing what not to drink matters just as much. Coffee, regular tea, alcohol, carbonated drinks, citrus juices (orange, grapefruit, lemon), and tomato juice are the most common liquid triggers. Carbonation increases pressure in the stomach, alcohol relaxes the lower esophageal valve, and acidic juices directly irritate already-inflamed tissue.
Chocolate milk, hot cocoa, and high-fat milkshakes belong on the avoid list too. And despite its popularity online, apple cider vinegar has zero published clinical evidence supporting its use for heartburn. Harvard Health has noted that no research in medical journals addresses using it for reflux, despite how widely it’s recommended on blogs. Since it’s highly acidic itself, it could easily make things worse.
How and When You Drink Matters
What you drink is only part of the equation. Volume and timing play a role too. Drinking large amounts of any liquid with a meal stretches the stomach, which can push its contents upward. Small, steady sips during meals are better than draining a full glass at once. If you tend to get reflux at night, try to finish your last significant drink at least two to three hours before lying down, just as you would with food.
Between meals, sipping water or herbal tea regularly helps keep the esophagus clear and dilutes any acid that’s crept upward. Keeping a water bottle nearby and drinking small amounts throughout the day is one of the simplest, most effective habits you can build for managing reflux over time.
