The fastest home remedy for heartburn is baking soda dissolved in water, which neutralizes stomach acid in minutes. But the “best” remedy depends on whether you need immediate relief or a longer-term strategy to stop heartburn from recurring. Several approaches work well, and combining a few of them tends to be more effective than relying on just one.
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 works by directly neutralizing hydrochloric acid in your stomach through a simple chemical reaction. The standard dose is half a teaspoon stirred into 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.
Relief typically comes within 5 to 15 minutes, making this the go-to option when heartburn hits and you need it gone now. The downside is that it’s short-lived. Your stomach keeps producing acid, so baking soda buys you time rather than solving the underlying problem. It’s also high in sodium, so it’s not a good daily habit for anyone watching their salt intake or managing blood pressure.
Chewing Gum After Meals
This one surprises people, but chewing sugar-free gum for 20 to 30 minutes after eating can meaningfully reduce heartburn. The mechanism is straightforward: chewing stimulates saliva production, and saliva naturally contains bicarbonate, the same acid-neutralizing compound found in baking soda. The extra swallowing also helps push any acid that’s crept into your esophagus back down into the stomach where it belongs.
Bicarbonate gum (sometimes marketed for oral health) works even better than regular sugar-free gum. Mint-flavored gum is worth avoiding, though. Peppermint relaxes the smooth muscle at the bottom of the esophagus, which is the very valve that’s supposed to keep acid from traveling upward.
Sleep on Your Left Side
If heartburn hits at night, your sleep position matters more than most people realize. Lying on your left side positions your esophagus and its muscular valve above the level of your stomach, letting gravity help acid drain back down. Sleeping on your right side does the opposite, making it easier for acid to pool at the junction between your stomach and esophagus.
Elevating the head of your bed by about 6 inches also helps. This doesn’t mean stacking pillows, which can bend your body at the waist and actually increase abdominal pressure. Instead, place blocks or a wedge under the head of the mattress so your entire upper body is on a gentle slope.
Ginger: Helpful but Complicated
Ginger has a long reputation as a digestive aid, and there’s some science behind it. It increases gastrointestinal motility and speeds up gastric emptying, meaning food moves through your stomach faster. Since a full, slow-to-empty stomach is a major heartburn trigger, this can help prevent reflux before it starts.
There’s a catch. Ginger also relaxes the lower esophageal sphincter, the muscular ring that acts as a one-way valve between your stomach and esophagus. A relaxed sphincter lets acid escape upward. So ginger may help some people and worsen symptoms in others, depending on whether their heartburn is driven more by slow digestion or by a weak sphincter. If you try it, small amounts are best: a thumb-sized piece of fresh ginger steeped in hot water as tea, or roughly a gram of powdered ginger.
Slippery Elm and Marshmallow Root
Both of these herbs contain a substance called mucilage that turns into a thick, slippery gel when mixed with water. That gel coats the lining of the esophagus and stomach, creating a physical barrier between your tissue and the acid irritating it. Slippery elm may also stimulate your gut to produce more of its own protective mucus, adding a second layer of defense.
You’ll find these as powders, lozenges, or capsules at most health food stores. Mixing a tablespoon of slippery elm powder into warm water and drinking it before meals or at bedtime is the traditional approach. The evidence here is mostly observational rather than from large clinical trials, but the safety profile is well established and many people find it soothing.
What About Apple Cider Vinegar?
Apple cider vinegar is one of the most commonly recommended heartburn remedies online, and one of the least supported by evidence. Harvard Health Publishing has noted that no research published in medical journals addresses using raw apple cider vinegar for heartburn. The theory that “low stomach acid causes reflux” circulates widely on blogs, but it doesn’t hold up well under scrutiny for most heartburn sufferers. Vinegar is also acidic enough to erode tooth enamel and irritate an already-inflamed esophagus. This is one remedy worth skipping.
Alginate Products
Alginates, derived from seaweed, are available over the counter and straddle the line between home remedy and medication. When they mix with stomach acid, they form a gel-like raft that floats on top of your stomach contents. This raft physically blocks acid from rising into the esophagus. Unlike antacids that neutralize acid chemically, alginates work as a mechanical barrier, which means they don’t change your stomach’s pH or interfere with digestion. They’re available as chewable tablets or liquid suspensions at most pharmacies.
Foods and Habits That Trigger Heartburn
Remedies work better when you’re not constantly re-triggering the problem. Certain foods relax the lower esophageal sphincter, making reflux more likely. Chocolate, peppermint, alcohol, and fatty or fried foods are the most consistent offenders. Citrus and tomato-based foods don’t relax the sphincter but are acidic enough to irritate tissue that’s already inflamed. Coffee and carbonated drinks can go either way depending on the person.
Meal size and timing matter just as much as what you eat. Large meals stretch the stomach and increase pressure on the sphincter. Eating within two to three hours of lying down means gravity can’t help keep acid in place. Tight clothing around the waist, particularly belts and high-waisted pants, increases abdominal pressure in the same way.
Weight Loss Has the Biggest Long-Term Impact
If heartburn is a recurring problem, body weight is the single most powerful lever you can pull. Excess abdominal fat increases pressure on the stomach and pushes acid upward. Research tracking women over 14 years found that a BMI decrease of about 3.5 points reduced the risk of frequent heartburn symptoms by nearly 40%. A separate hospital-based study found that losing just 5 to 10% of body weight led to significant reductions in overall reflux symptom scores. For someone weighing 200 pounds, that’s 10 to 20 pounds.
This isn’t a quick fix, obviously. But for people who deal with heartburn multiple times a week, it’s the intervention most likely to make the problem go away rather than just masking it.
Signs That Need Medical Attention
Most heartburn is uncomfortable but harmless. Certain symptoms, however, suggest that acid has caused real damage or that something else is going on. The American College of Gastroenterology identifies these red flags: difficulty swallowing or a feeling that food is stuck behind your chest, vomiting blood or material that looks like coffee grounds, black or tarry stools, unexplained weight loss, and chronic hoarseness or coughing that seems connected to reflux. Any of these warrants a prompt conversation with a doctor rather than another round of home remedies.
