How Much Baking Soda Can You Safely Drink?

The Curiosity Around Baking Soda Remedies

Most people keep a box of baking soda stashed at the back of the pantry. Some sprinkle it in recipes, others deodorize their fridge, and now and then, someone wonders about drinking it for heartburn relief or that old “detox” tip making the rounds.

Growing up, I watched family members stir a half-teaspoon of baking soda into a glass of water during a bout of indigestion. They’d swear by its quick relief. The logic seems simple enough: baking soda, or sodium bicarbonate, neutralizes stomach acid. No need to pop a pill, just reach for the kitchen staple. Still, most folks don’t realize how far a small dose can go—or the risks.

Understanding Baking Soda’s Effects on the Body

Let’s get real about what happens when you drink baking soda dissolved in water. One-half teaspoon of sodium bicarbonate (about 2.5 grams), mixed with at least a half-cup of water, temporarily neutralizes stomach acid. The chemistry checks out; the sensation of relief feels convincing. This home remedy isn’t just folklore. Medical resources, including the U.S. National Library of Medicine, confirm that baking soda works as an antacid.

Here’s the catch: Sodium bicarbonate comes packed with sodium—the same stuff that sends blood pressure soaring if consumed in excess. One-half teaspoon carries 630 milligrams of sodium. For those with hypertension, heart, kidney, or liver problems, that’s a significant dose. Baking soda also reacts in the stomach to produce carbon dioxide, which means belching is part of the deal.

The Dangers of Overdoing It

Social media sometimes amplifies unproven health trends. Over the past few years, I’ve seen people doubling or tripling doses because more must be better, right? That idea gets folks in trouble. Doctors report patients who gulp too much baking soda end up with metabolic alkalosis—a potentially serious condition where the body’s pH tips out of balance. It sends some people to the emergency room, battling muscle cramps, tremors, and even confusion. A handful of tragic stories confirm the risk for seizures or heart rhythm problems in extreme cases.

One medical review in the journal Clinical Toxicology notes that “serious outcomes have occurred following sodium bicarbonate ingestion, particularly with excessive doses.” Many only think about the stomach, but the kidneys work hard to clear both sodium and excess bicarbonate, adding further strain.

Smart Solutions for Safe Use

Instead of chasing viral ideas and risking health, consider guidance from trusted sources. If occasional heartburn bothers you, reach for half a teaspoon, dissolved in water, and stick to that amount no more than once every four hours. Top medical organizations advise no more than 3½ teaspoons in a day for adults. Use for more than two weeks signals a need to talk with a doctor.

People with chronic health conditions, those taking daily prescriptions (like aspirin or blood pressure pills), should steer clear unless a physician gives the green light. Pregnant women and children face greater risks from sodium overload. Drug interactions can make a bad day even worse, so check with your pharmacist before self-medicating.

Sometimes the simplest solution—like quitting fatty or spicy food, eating smaller meals, or cutting back on coffee—works better than chasing relief with baking soda. Modern antacids, designed specifically for stomach issues, sidestep most sodium risks. As for the famous detox pitch? No scientific support backs drinking baking soda for “cleansing” healthy bodies.

It’s good to use baking soda to settle your stomach in a pinch, but respect the measure and know when to seek better answers.
