Home Remedies for Acid Reflux That Actually Work

Several home remedies for acid reflux have genuine evidence behind them, though the strongest performers are not the ones that tend to go viral on social media. Sleeping on your left side, waiting at least three hours after dinner before lying down, and elevating the head of your bed all have solid backing from clinical studies. Others, like chewing gum after meals and certain dietary shifts, sit on a smaller but still credible evidence base. And a few popular suggestions, like drinking apple cider vinegar, can actually make things worse.

Sleep on Your Left Side

If you deal with nighttime reflux, the single most effective free thing you can do is sleep on your left side. The anatomy behind this is straightforward: your stomach curves in a way that, when you lie on the left, the junction where your esophagus meets your stomach sits above the pool of gastric acid. Flip to your right side, and that junction essentially dips below the acid line, making it far easier for stomach contents to wash back up.

A study using simultaneous sleep-position tracking and esophageal pH monitoring found that acid exposure time in the left-side position had a median of 0.0%, compared to 1.2% on the right side and 0.6% while lying on the back. Acid clearance time was also dramatically shorter on the left: a median of 35 seconds versus 90 seconds on the right side and 76 seconds while supine.¹ An earlier study found the same pattern, with right-side sleeping producing greater acid exposure and slower esophageal clearance compared to all other positions.² A systematic review and meta-analysis confirmed these findings across multiple studies, showing consistently reduced acid exposure in the left-side position compared to both right-side and supine sleeping.³

If you tend to roll over during the night, wedge-style body pillows or purpose-built positional devices can help you stay put. Some people stuff a tennis ball into a pocket sewn onto the right side of their pajama top, which sounds ridiculous but works for the same reason: it makes the wrong position uncomfortable enough that you shift back without fully waking up.

Raise the Head of Your Bed

Propping your upper body higher than your stomach gives gravity a chance to work in your favor. This does not mean stacking pillows, which tends to bend you at the waist and can actually increase abdominal pressure. The effective version is elevating the entire head of your bed frame by about six to eight inches, using blocks under the legs or a foam wedge that runs from your hips to your head. A study of patients with nighttime reflux found that this approach reduced esophageal acid exposure, shortened acid clearance time, and brought some relief from both heartburn and sleep disturbance.⁴

If you share a bed and your partner does not want to sleep on a slope, a wedge pillow that covers just your half is a reasonable compromise. The key is that your torso from the waist up is angled, not just your neck. A pile of regular pillows only elevates your head and can kink your esophagus into a position that traps acid rather than draining it.

Wait at Least Three Hours After Eating to Lie Down

This one sounds like old-fashioned advice, and it is, but the data behind it are striking. A study examining the relationship between dinner-to-bed time and reflux found that people who lay down less than three hours after their evening meal had over seven times the odds of experiencing reflux compared to those who waited four hours or more.⁵ That is one of the larger effect sizes you will find for any lifestyle modification in reflux research.

The mechanism is simple: your stomach needs time to move food along before you take gravity out of the equation. If you eat late and then lie flat, your stomach is full of acid and partially digested food at the exact moment your esophagus loses its gravitational advantage. For people whose reflux flares mostly at night, adjusting dinner timing can be as effective as some medications. If a late dinner is unavoidable, staying upright afterward, even just sitting on the couch rather than reclining, buys your stomach some processing time.

Chewing Gum After Meals

Chewing gum stimulates saliva production, and saliva is mildly alkaline, so swallowing it repeatedly helps wash acid back down into the stomach and neutralize what is left behind in the esophagus. A study found that chewing a gum base roughly doubled salivary flow rate and cut esophageal acid clearance time from about seven minutes to about two minutes.⁶ That is a meaningful reduction in how long your esophagus sits in an acidic environment after a reflux episode.

Sugar-free gum is preferable since you will be chewing for a while. Mint-flavored gum is worth a separate conversation (covered below), but the benefit comes from the chewing itself, not the flavor. About 20 to 30 minutes of post-meal chewing seems to be the practical sweet spot.

Dietary Carbohydrate Changes

The idea that what you eat matters for reflux is not new, but the specific dietary changes that help are not always the ones people expect. While most people focus on spicy food or citrus, the more interesting research involves carbohydrate intake. A small study of obese individuals with reflux found that a very low-carbohydrate diet cut their esophageal acid exposure time roughly in half and significantly improved symptom scores.⁷

A more nuanced randomized trial tested different types and amounts of carbohydrates. The group that ate high total carbohydrates but kept simple sugars low saw the largest improvement, with acid exposure time dropping by about four percentage points. Meanwhile, the control group eating high total carbs with high simple sugars saw their acid exposure time increase. Participants across the carbohydrate-modification groups reported reductions in heartburn frequency, heartburn severity, acid taste in the mouth, and sleep disturbance.⁸ The takeaway is less about going on a strict low-carb diet and more about cutting back on simple sugars and refined carbohydrates, which may reduce reflux through effects on stomach distension and gut fermentation.

High-fat meals are another well-established trigger. Fat slows gastric emptying and increases the perception of reflux symptoms.⁹ You do not need to eliminate fat from your diet, but if you notice reflux flaring after fried food, creamy sauces, or fatty cuts of meat, that pattern has a physiological explanation and cutting back is a reasonable first step.

Loosen Your Belt

Tight clothing around your midsection is not just uncomfortable when you are bloated; it can physically push stomach contents upward. A study that had people eat a meal with and without an abdominal compression belt found that the mean number of reflux events roughly doubled with the belt on: four episodes versus two without it. The mechanism was primarily impaired esophageal clearance rather than increased reflux generation, meaning the acid that came up took longer to drain back down.¹⁰ If you wear a tight belt, shapewear, or high-waisted pants that dig in after meals, switching to something looser, at least during and after eating, is an easy win.

Diaphragmatic Breathing Exercises

This one surprises people, but it has a logical basis. Your diaphragm is not just a breathing muscle; part of it wraps around the bottom of your esophagus and acts as a physical barrier against reflux. Training that part of the diaphragm through specific breathing exercises can strengthen it, tightening that barrier. A systematic review found that diaphragmatic breathing training has the potential to reduce symptoms in people with reflux because it targets the diaphragm’s role at the junction between the esophagus and stomach.¹¹

A randomized controlled trial tested this directly, having patients do daily breathing exercises that focused on deep, slow diaphragmatic breaths. The training group showed improvements in esophageal acid measurements, quality-of-life scores, and reduced their use of proton pump inhibitors.¹² The practical version is simple: sit or lie comfortably, place one hand on your chest and one on your belly, and breathe slowly so that only the belly hand rises. Aim for about four seconds inhaling, a brief hold, and six seconds exhaling. Doing this for ten to fifteen minutes a day is the rough protocol from the research. It is free, has no side effects, and if it does not help your reflux, it will at least lower your stress, which can itself be a reflux trigger.

Weight Loss

Carrying extra weight, especially around the abdomen, increases pressure on the stomach and promotes reflux. A prospective trial found that weight loss can lead to resolution of reflux symptoms.¹³ This is not a quick fix, but for people who are overweight and deal with chronic reflux, even a modest reduction in weight can make a noticeable difference. The effect is mechanical: less abdominal fat means less upward pressure on the stomach, which means fewer opportunities for acid to push past the lower esophageal sphincter.

Ginger for Stomach Motility

Ginger gets recommended constantly for nausea, but its relevance to reflux is more specific than most people realize. The issue for many reflux sufferers is that food sits in the stomach too long, generating acid and creating pressure. Ginger appears to speed up gastric emptying: a study in healthy volunteers found that ginger cut the stomach’s half-emptying time from about 16 minutes to about 12 minutes and stimulated contractions in the lower stomach.¹⁴ A separate trial confirmed the same pattern, with ginger powder producing faster gastric emptying and enhanced antral contractions compared to placebo.¹⁵

The research on ginger and stomach emptying comes primarily from studies on functional dyspepsia (a condition with significant symptom overlap with reflux) rather than reflux trials specifically.¹⁶ So the evidence is suggestive rather than definitive for reflux. A cup of ginger tea or a small amount of fresh ginger before or after meals is unlikely to cause harm and may help if slow stomach emptying is part of your problem. Avoid ginger supplements in very high doses, which can themselves cause heartburn.

Aloe Vera and Deglycyrrhizinated Licorice

Two herbal remedies show up repeatedly in reflux discussions, and both have at least some clinical evidence. A pilot randomized trial found that aloe vera syrup reduced the frequency of all assessed reflux symptoms compared to baseline and was well tolerated with no adverse events requiring withdrawal.¹⁷ The study was small and described as a pilot, so it is not strong enough to call aloe vera a proven treatment, but it suggests the approach is worth exploring.

Deglycyrrhizinated licorice, usually sold as DGL, is licorice root with most of the compound glycyrrhizin removed. That removal matters: regular licorice can cause high blood pressure, water retention, and electrolyte imbalances. A phase III trial tested a standardized DGL extract for managing reflux-related symptoms, with the product designed to keep glycyrrhizin below 3% specifically to avoid those side effects.¹⁸ If you try DGL, make sure you are getting the deglycyrrhizinated version. Regular licorice supplements or licorice candy consumed regularly can cause real problems.

Remedies That Are Overhyped or Risky

Not everything that gets shared as a “natural cure” deserves a place in your routine. A few popular suggestions range from unsupported to actively dangerous.

Apple cider vinegar is probably the most widely circulated home remedy for reflux, and the logic behind it makes no physiological sense. The idea that adding acid to an already acidic stomach would reduce acid-related symptoms has no clinical support. Worse, vinegar is itself a corrosive agent. A case report documented esophageal injury from a commercial vinegar beverage, with continuous consumption resulting in acidic burns and destruction of the upper digestive tract lining.¹⁹ Diluting it does not necessarily make it safe for an already inflamed esophagus.

Baking soda (sodium bicarbonate) does neutralize acid, and people have used it for decades as a quick heartburn fix. A half teaspoon dissolved in water will often provide fast, temporary relief. The problem is the temptation to overdo it. Case reports describe severe metabolic alkalosis from excessive baking soda ingestion, with risks including dangerous electrolyte imbalances and even reduced blood oxygen levels.²⁰ Occasional use in small amounts is generally fine for most adults, but it should not become your daily go-to. It is also very high in sodium, which matters if you have high blood pressure or are on a sodium-restricted diet.

The Mint Question

Mint has been on the “avoid” list for reflux patients for decades, with the traditional explanation being that peppermint relaxes the lower esophageal sphincter and allows acid to flow upward. The reality appears more complicated. A study that directly infused menthol into the esophagus of both healthy volunteers and reflux patients found that it did not appreciably affect esophageal motility or lower esophageal sphincter pressure in either group.²¹ The contractile strength of the esophagus and the pressure at the sphincter were essentially unchanged.

This does not mean mint is risk-free for everyone. Some people clearly report worsening symptoms after peppermint tea or minty foods, and subjective symptom triggers vary from person to person. But the blanket instruction to avoid all mint may be based on outdated assumptions. If you have never noticed mint bothering you, there is no strong reason to eliminate it preemptively.

Alginate-Based Products

Over-the-counter alginate products, made from seaweed-derived compounds, occupy a space between home remedies and medications. When mixed with stomach acid, they form a floating gel “raft” on top of your stomach contents. If reflux does occur, the raft tends to be what comes up first, acting as a physical barrier rather than a chemical one. Research into the chemical properties of these rafts confirms that they can effectively impede reflux into the esophagus or, when refluxed themselves, exert a soothing effect on the esophageal lining.²² These products are available without a prescription in most countries and are considered safe for long-term use, including during pregnancy, which is when reflux tends to become a constant companion for many people.

Alkaline Water

You will see alkaline water marketed aggressively for reflux, and there is a grain of science behind the claims, though it is a small grain. An in vitro study found that water at pH 8.8 irreversibly inactivated human pepsin, the stomach enzyme responsible for much of the damage during reflux episodes. Its acid-buffering capacity also far exceeded that of conventional tap or bottled water.²³ That sounds promising, but the key phrase is “in vitro,” meaning in a lab dish rather than inside a human body. No large clinical trial has demonstrated that regularly drinking alkaline water reduces reflux symptoms in real patients. It is not harmful, but spending significant money on specialty alkaline water when a glass of regular water after a reflux episode can also help dilute and clear acid is probably not the best use of your budget.

When Home Remedies Are Not Enough

Home remedies work best for occasional or mild reflux. If you are experiencing heartburn more than twice a week, having trouble swallowing, waking up choking, or noticing unexplained weight loss alongside your symptoms, those are signals that something more than lifestyle adjustment is needed. Persistent untreated reflux can damage the esophageal lining over time, and some conditions that mimic reflux, like eosinophilic esophagitis or even cardiac problems, need their own specific treatment. The remedies discussed here are useful tools for managing symptoms and reducing how often reflux happens, but they work best as complements to medical care rather than replacements for it when symptoms are frequent or severe.
