Several home remedies can ease acid reflux quickly, and a few simple habit changes can keep it from coming back. The most effective options work by either neutralizing stomach acid, protecting the lining of your esophagus, or helping your stomach empty faster so acid has less opportunity to travel upward.
Baking Soda for Fast Relief
Baking soda (sodium bicarbonate) is the closest thing to an over-the-counter antacid you already have in your kitchen. It directly neutralizes stomach acid on contact. The standard approach is half a teaspoon dissolved in a full glass of cold water, taken after meals. You can repeat this every two hours if needed, but don’t exceed five teaspoons in a single day.
This is strictly a short-term fix. The Mayo Clinic advises against using baking soda for more than two weeks straight. Overuse, especially in large doses or by people with kidney problems, can shift your body’s acid-base balance in ways that cause more harm than the heartburn itself. If you’re reaching for baking soda regularly, that’s a sign to look into longer-term solutions.
Chew Sugar-Free Gum After Meals
This one sounds too simple to work, but the science is solid. Chewing gum stimulates saliva production, and saliva is naturally rich in bicarbonate, the same acid-neutralizing compound in baking soda. When you swallow that extra saliva, it washes acid back down out of your esophagus and buffers whatever acid is sitting there. A study from King’s College London found that chewing sugar-free gum for 30 minutes after a meal significantly reduced acid exposure in the esophagus. Keep a pack in your bag or by the dinner table.
Ginger for Slow-Moving Stomachs
Ginger has a long folk-medicine reputation for settling the stomach, and clinical research gives it some backing. A trial published in the World Journal of Gastroenterology tested 1,200 milligrams of ginger root powder (about a quarter teaspoon) and found it stimulated stronger stomach contractions and faster gastric emptying. That matters for reflux because the longer food sits in your stomach, the more acid your stomach produces and the higher the pressure pushing acid upward.
The exact mechanism isn’t fully understood, but ginger appears to act on serotonin receptors in the gut that help coordinate muscle contractions. You can take it as a capsule, brew fresh ginger slices into tea, or grate it into meals. Start with a small amount to make sure it agrees with you, since concentrated ginger on a completely empty stomach can cause its own irritation.
Slippery Elm and DGL Licorice
Both of these work as demulcents, meaning they form a gel-like coating that physically protects irritated tissue. Slippery elm bark, when mixed with water, produces a thick mucilage that can coat and soothe the esophagus as it goes down. It’s typically sold as a powder you stir into warm water or as lozenges. The relief is mechanical rather than chemical: a protective layer between your tissue and the acid.
Deglycyrrhizinated licorice (DGL) works similarly. Health Canada lists it as an approved herbal medicine for relieving minor inflammation of the gastrointestinal tract, including stomach burning and abdominal pain. The recommended dose is 380 to 1,520 milligrams, chewed between meals or about 20 minutes before eating, up to three times a day. DGL is a specific form of licorice with a compound called glycyrrhizin removed. That distinction matters, because regular licorice in large amounts can raise blood pressure and cause potassium imbalances. DGL avoids that problem.
What About Apple Cider Vinegar?
Despite its popularity online, apple cider vinegar has no published clinical evidence supporting its use for heartburn. Harvard Health Publishing reviewed the available literature and found zero studies in medical journals testing it for acid reflux. The theory behind it, that low stomach acid causes the valve at the top of your stomach to relax, oversimplifies how that valve actually works. The valve responds to a complex mix of involuntary muscles, hormones, and neurotransmitters, not just acidity levels.
Apple cider vinegar is also a strong acid itself, with a pH around 2 to 3. Drinking it undiluted can irritate or damage the esophagus, which is exactly the tissue you’re trying to protect. If you want to try it anyway, dilute a small amount in warm water and drink it with food, but don’t expect it to replace remedies that have actual evidence behind them.
Habit Changes That Reduce Reflux
Home remedies work best alongside a few practical adjustments to when and how you eat.
Wait before lying down. Gravity is your cheapest antacid. Experts recommend staying upright for at least two to three hours after eating before you lie down or go to bed. That window gives your stomach enough time to process most of a meal and lowers the pressure that pushes acid into your esophagus. If you can manage only a short wait, even staying upright for 30 minutes makes a measurable difference.
Elevate the head of your bed. Stacking extra pillows under your head doesn’t work well because it bends your body at the waist, which can actually increase abdominal pressure. Instead, raise the entire head of your bed by 3 to 6 inches using blocks under the bed frame legs or a foam wedge pillow placed under your mattress. This keeps your esophagus above your stomach all night without folding your body.
Eat smaller meals. A full stomach puts more pressure on the valve between your stomach and esophagus. Smaller, more frequent meals keep that pressure lower. This is especially important in the evening, when you’re heading toward hours of lying flat.
Identify your trigger foods. Common culprits include chocolate (which contains a compound that relaxes the esophageal valve), coffee, alcohol, citrus, tomato-based foods, and high-fat or fried meals. Triggers vary from person to person, so paying attention to which foods consistently cause problems for you is more useful than following a generic avoidance list.
Signs That Home Remedies Aren’t Enough
Occasional reflux responds well to the strategies above. But certain symptoms suggest something more serious is going on. The American College of Gastroenterology flags these as warning signs that need medical attention: difficulty swallowing or a feeling that food is getting stuck behind your chest, vomiting blood (which can look like red clots or dark coffee grounds), black or tarry bowel movements, choking sensations with coughing or hoarseness, and unexplained weight loss with an inability to tolerate food. If reflux is happening more than twice a week for several weeks, that pattern also warrants a professional evaluation, since chronic acid exposure can damage the esophagus over time in ways you won’t necessarily feel.
