The fastest home remedy for heartburn is baking soda dissolved in water, which can neutralize stomach acid within minutes. Half a level teaspoon stirred into four ounces of water works as a basic antacid you likely already have in your kitchen. But several other strategies can speed up relief or prevent the burning from getting worse, and combining a few of them works better than relying on just one.
Baking Soda: The Fastest Kitchen Fix
Sodium bicarbonate (baking soda) is the active ingredient in many commercial antacids, and it works by directly neutralizing the hydrochloric acid in your stomach. The recommended amount is half a level teaspoon in half a glass of water. You can repeat this every two hours if needed, but don’t exceed six half-teaspoon doses in 24 hours. If you’re over 60, keep it to three doses max per day.
The relief is quick, often within five to ten minutes, but it doesn’t last long. Baking soda also contains a significant amount of sodium, so it’s not a good daily habit. Think of it as an emergency option for occasional flare-ups, not a regular treatment plan.
Change Your Position Immediately
If you’re lying down when heartburn hits, sit up or stand. Gravity alone helps keep stomach acid from pushing up into your esophagus. If it’s nighttime and you need to stay in bed, prop your upper body up with pillows or a wedge so your head and chest are elevated above your stomach. Lying flat is one of the most reliable ways to make heartburn worse.
While you’re at it, loosen anything tight around your midsection. Tight waistbands, belts, and shapewear compress your abdomen and push acid upward. Swapping into loose pajama pants or unbuckling your belt can make a noticeable difference surprisingly fast.
Chew a Piece of Sugar-Free Gum
This one sounds too simple, but it has real science behind it. Chewing gum stimulates saliva production, and saliva is mildly alkaline, meaning it helps neutralize acid. More importantly, chewing makes you swallow more frequently, which clears acid out of your esophagus faster. Research from King’s College London found that chewing sugar-free gum for 30 minutes after a meal reduced acid levels in the esophagus. Keep a pack in your kitchen or nightstand for easy access after heavy meals.
Over-the-Counter Options at Home
If you keep antacids like calcium carbonate tablets in your medicine cabinet, they’re the fastest pharmacy-grade option. They neutralize acid on contact and typically bring relief within minutes. The trade-off is that the effect wears off relatively quickly.
H2 blockers (the other common type of heartburn medication sold over the counter) take about an hour to kick in. They work differently: instead of neutralizing existing acid, they reduce how much acid your stomach produces. This means they last longer but aren’t ideal when you need relief right now. If you’re dealing with heartburn in the moment, reach for an antacid first. If you know a heavy meal is coming, taking an H2 blocker beforehand can prevent the flare from starting.
What to Avoid While You’re Feeling It
Some foods and drinks actively make heartburn worse by relaxing the muscular valve between your stomach and esophagus. When that valve loosens, acid escapes upward more easily. While you’re trying to calm a flare-up, stay away from:
- Coffee and caffeinated drinks, including decaf coffee, which relaxes the valve regardless of caffeine content
- Chocolate, which contains a compound similar to caffeine that has the same valve-relaxing effect
- Peppermint, including peppermint tea, which many people mistakenly reach for to soothe their stomach
- Fatty or fried foods, which both relax the valve and slow digestion, keeping acid in your stomach longer
- Garlic and onions, which have the same relaxing effect on the valve
It’s also worth skipping alcohol and carbonated drinks during a flare. If you’re hungry, stick to something bland and low-fat, like plain bread, rice, or a banana.
Ginger: Helpful but Limited
Ginger tea or fresh ginger is a popular home remedy, and there’s some logic to it. Ginger contains compounds that may reduce irritation in the digestive tract and calm stomach spasms. However, the honest picture is that most clinical research on ginger focuses on nausea, not acid reflux specifically. There’s no strong evidence that it reliably treats heartburn. A small cup of ginger tea is unlikely to hurt and might take the edge off, but don’t count on it as your primary solution when you’re in real discomfort.
When Chest Pain Isn’t Heartburn
Heartburn produces a burning sensation in the chest, typically after eating, and it often comes with a sour taste in the mouth or a feeling of food rising into the back of your throat. It usually improves when you take an antacid.
A heart attack can feel like pressure, tightness, or squeezing in the chest or arms, often spreading to the neck, jaw, or back. It may come with shortness of breath, cold sweats, sudden dizziness, or unusual fatigue. If your chest pain doesn’t feel like typical heartburn, or if it comes with any of those additional symptoms, call emergency services. Heart attacks are sometimes mistaken for heartburn, and the consequences of guessing wrong are serious.
Putting It All Together
For the fastest relief, combine strategies. Sit upright, loosen your clothing, and take baking soda in water or an antacid tablet. Start chewing sugar-free gum. Avoid everything on the trigger list above, and don’t lie down for at least two to three hours after eating. Most mild to moderate heartburn episodes will fade within 20 to 30 minutes with this approach. If you’re getting heartburn more than twice a week, that pattern points toward something more persistent that’s worth investigating beyond home remedies.
