Can You Use Baking Soda for Heartburn?

Looking for Relief in the Kitchen

Reaching for kitchen remedies feels natural during a bout of heartburn. Baking soda is a household staple, sitting in pantries for cakes but also known as a traditional fix for stomach acid. Growing up, I heard older relatives swear by a teaspoon of baking soda in water after a big meal. The fizz made it seem like something magical happened, and often, folks felt relief soon after.

How Baking Soda Works in the Body

Baking soda, or sodium bicarbonate, neutralizes acid on contact. This simple reaction explains why many use it for heartburn: the burning sensation comes from acid slipping up into the esophagus. Mixing half a teaspoon of baking soda into water and sipping it down can put out that fire for a while. It works quickly and costs almost nothing.

Science backs up this effect. Sodium bicarbonate has a long history in medicine as an antacid. The American Heart Association and medical textbooks recognize sodium bicarbonate as a temporary fix, especially in emergencies where other antacids are out of reach.

The Downsides Most Don’t Talk About

Baking soda works, but it’s not designed for regular use. Swallowing too much sodium, whether from processed food or home remedies, does the body no favors. Each teaspoon contains around 1,259 milligrams of sodium. That’s about half the recommended daily limit in a single gulp. For those with high blood pressure, kidney disease, or heart problems, this could tip the balance toward health trouble.

I remember my neighbor using this method daily. After a few weeks, he started to feel bloated and lightheaded. Turns out, the extra salt put a strain on his blood pressure. Doctors don’t recommend baking soda for routine heartburn because repeated use leads to more than just a salty taste in the mouth. There’s a risk of metabolic alkalosis—where the body’s pH gets thrown off—plus the risk of swelling, muscle spasms, and other electrolyte problems.

Fact-Checking Tradition: Safety First

The FDA and top health organizations say baking soda can work short-term for healthy adults as long as they keep servings small and infrequent. Mixing half a teaspoon in a four-ounce glass of water can take the sting out of heartburn, but this remedy should never become a daily habit. This practical use lines up with evidence. Peer-reviewed research in therapeutic journals supports this advice: sodium bicarbonate is reserved for occasional, acute relief, not a permanent solution.

If heartburn happens often, this points to something deeper, such as gastroesophageal reflux disease (GERD) or issues with diet and lifestyle. Over-the-counter antacids, proton pump inhibitors, or advice from a doctor offer safer, more sustainable fixes.

Practical Solutions for Lasting Relief

From my own struggles, a few changes in daily life beat any kitchen hack. Cutting back on acidic foods, finishing dinner earlier, propping up pillows at night, and shedding a few pounds helped me tame heartburn more than chasing instant relief ever did.

Quick fixes fill a gap, but heartburn deserves more respect. For anyone tempted to try baking soda, checking in with a healthcare provider avoids bigger problems down the road and keeps the heart—and the rest of the body—safe.
