Baking soda mixed in water typically starts neutralizing stomach acid within a few minutes, with most people feeling relief from heartburn in about 5 to 15 minutes, though the effect often fades within an hour or two. Dosing matters: the common approach is 1/2 teaspoon of baking soda in 4 ounces of water, no more than once every two hours, and it should not be used for more than a week or by people on a low-sodium diet, those with kidney or heart problems, or those who are pregnant without medical guidance. Speed and effectiveness also depend on whether your stomach is full, how severe the reflux is, and whether other medications are involved, since baking soda can interfere with how some drugs are absorbed. Frequent heartburn that keeps returning after antacids may point to GERD, a hiatal hernia, an ulcer, or another condition that needs different treatment. There are several important safety details and timing factors to consider, so see below to understand more.
If heartburn keeps coming back, lasts longer than expected, or comes with trouble swallowing, chest pressure, vomiting, or unexplained weight loss, it is worth looking deeper than a quick home remedy. A free, instant, online symptom check takes only a few minutes, helps you sort ordinary acid reflux from conditions that deserve prompt attention, and gives you clear, personalized guidance on what to do next and which type of clinician to see. Understanding the likely cause now can spare you weeks of guesswork and repeated doses of a remedy that was never meant for long-term use.

Heartburn affects millions of people each year. If you’ve experienced that burning sensation in your chest after a heavy meal or late-night snack, you know how uncomfortable it can be. Many home remedies promise quick relief—one of the most common being baking soda. Below, we’ll explore how baking soda for heartburn works, how fast it typically takes effect, safe dosing guidelines, and when to seek professional help.
Heartburn occurs when stomach acid backs up into the esophagus (the tube connecting your throat to your stomach). This acid reflux causes:
