A half teaspoon of baking soda stirred into a glass of cold water is one of the fastest home remedies for heartburn, often neutralizing stomach acid within minutes. But it’s far from your only option. Several simple strategies can ease that burning feeling behind your breastbone without a trip to the pharmacy, and knowing which ones actually work (and which don’t) can save you discomfort.
Baking Soda: The Fastest Fix
Baking soda (sodium bicarbonate) directly neutralizes stomach acid on contact. The standard dose for adults is half a teaspoon dissolved in a full glass of cold water, taken after meals, and repeated every two hours if needed. Don’t exceed five teaspoons in a single day, and don’t rely on it for more than two weeks straight.
The catch is sodium. A single teaspoon of baking soda contains roughly 1,259 milligrams of sodium, which is more than half the daily recommended limit. If you have high blood pressure, kidney problems, or are on a sodium-restricted diet, this remedy can cause more harm than good. For occasional heartburn in otherwise healthy adults, though, it’s effective and nearly instant.
Chewing Gum After Meals
This one sounds too simple to work, but it does. Chewing sugar-free gum for 20 to 30 minutes after eating stimulates saliva production, and saliva naturally contains bicarbonate, the same acid-neutralizing compound found in baking soda. The extra saliva washes acid back down out of your esophagus, and the repeated swallowing helps clear it faster. Bicarbonate gum, if you can find it, amplifies the effect. It won’t stop a severe episode, but as a mild preventive habit after meals, it’s surprisingly useful.
Change How You Sleep
Heartburn that hits at night responds well to two changes in your sleeping setup. First, elevate the head of your bed by about six inches using blocks or a wedge pillow. Gravity keeps acid where it belongs. Stacking regular pillows doesn’t work as well because it bends your body at the waist rather than creating a true incline.
Second, sleep on your left side. When you lie on your left, your esophagus and the muscular ring that separates it from your stomach sit higher than the stomach itself. Acid drains away from the esophagus more quickly in this position compared to lying on your right side or your back. If nighttime heartburn is your main problem, this single habit change can make a noticeable difference.
Aloe Vera Juice
A small 2015 study found that aloe vera juice reduced stomach acid levels enough to relieve heartburn symptoms. It’s widely available at grocery stores, though you want to look for versions labeled “decolorized” or “purified,” which have had the harsh latex compounds removed. Start with a few ounces to see how your body handles it before working up to a full cup per day. Drinking too much too quickly can cause cramping or diarrhea, and repeated loose stools can throw off your electrolyte balance. If your stomach reacts poorly, scale back to every other day or every third day.
Why Milk Is Unreliable
Reaching for a glass of milk feels intuitive because the cool liquid coats your throat and seems to soothe the burn. Skim milk does contain calcium and protein that can briefly neutralize acid and tighten the muscular valve at the top of your stomach. But the relief is temporary and potentially counterproductive.
Protein triggers the release of a hormone called gastrin, which strengthens that valve but also signals your stomach to produce more acid. The net effect is unclear. Whole milk is worse: its fat content relaxes the valve between your stomach and esophagus, making reflux more likely, and fat slows digestion so food sits in your stomach longer. That means more acid, more pressure, and more opportunity for it to splash upward. If you want to try milk, stick to skim, but don’t expect lasting results.
Apple Cider Vinegar: Skip It
Apple cider vinegar is one of the most commonly recommended heartburn remedies online, but there is no published clinical research supporting its use for this purpose. Harvard Health Publishing reviewed the evidence and found zero studies in medical journals addressing whether it helps. The logic behind it (that adding acid to an acidic stomach could somehow reduce reflux) doesn’t hold up physiologically. Vinegar is also acidic enough to irritate an already-inflamed esophagus, potentially making things worse.
Lifestyle Habits That Prevent Flare-Ups
Home remedies work best alongside a few practical changes that reduce how often heartburn strikes in the first place:
- Eat smaller meals. A full stomach puts more pressure on the valve that keeps acid from rising.
- Wait two to three hours after eating before lying down. Gravity is your ally while you’re upright.
- Avoid trigger foods. Tomato sauce, citrus, chocolate, coffee, alcohol, and spicy or fried foods are the most common culprits, though your personal triggers may differ.
- Wear loose clothing. Tight waistbands compress your abdomen and push acid upward.
- Lose weight if you carry extra pounds around your midsection. Abdominal fat increases pressure on your stomach in the same way a tight belt does, just from the inside.
When Home Remedies Aren’t Enough
Occasional heartburn after a heavy meal is normal. Heartburn that shows up more than twice a week, persists for weeks, or keeps returning after home treatment may signal gastroesophageal reflux disease (GERD), which requires stronger intervention. Pay attention to symptoms that go beyond the typical burn: difficulty swallowing, a sensation of food getting stuck in your chest or throat, unexplained weight loss, persistent hoarseness, or vomiting. These can indicate damage to the esophagus or other conditions that home remedies won’t address.
