What Really Happens When You Drink Baking Soda

People Have Been Mixing Baking Soda with Water for Years

Growing up, my grandmother kept a yellow box of baking soda on the kitchen counter and used it for nearly everything. She’d sprinkle it into dough, scrub pans with it, and—I once watched her stir it into a cup of cold water, pinch her nose, and chug it down after a big meal. I never questioned her, but now that I see people online claiming it boosts metabolism and balances your body, I realize not everyone knows why baking soda has this reputation or what real science says about it.

What's in That Little Blue Box?

Baking soda is sodium bicarbonate. Add water, and you get a mildly salty, slightly fizzy drink. In the kitchen, it makes bread rise by releasing gas. In the body, it acts as an antacid. When your stomach churns out too much acid—maybe from spicy food or stress—baking soda neutralizes it, sometimes giving quick relief from heartburn. That’s the real, time-tested use. Pharmacies sell sodium bicarbonate tablets for similar reasons.

My Experience with the Home Remedy

I tried baking soda in water twice, both times for heartburn after a late-night meal. Swallowed fast enough, it settled the burning that crept up my throat. But that glass sat heavy in my stomach and left me burping. Drinking more than a little would have made me sick. That’s the experience many share: quick relief, but it feels like you swallowed a puff of wind. This home fix isn’t a daily plan. There’s a reason my grandmother reached for it once or twice a month, not every week.

Online Claims vs. Medical Reality

Plenty of social media posts claim this trick can “alkalize your body,” boost exercise performance, even fight diseases. These ideas miss how the body works. Our kidneys keep blood pH tightly controlled. Drinking baking soda doesn’t magically clean out “acidic waste.” Too much sodium, on the other hand, puts stress on the kidneys and heart. A teaspoon mixed into a glass of water packs about 1,250 mg of sodium. If you already carry high blood pressure or heart problems, that extra salt poses risk. Doctors warn against regular use for just this reason.

Baking Soda in Sports? Only Under Careful Control

Some high-level athletes use baking soda before intense competition. There’s real research suggesting it helps buffer lactic acid, delaying fatigue during short, all-out bursts. Coaches use carefully measured doses—usually less than a teaspoon—well before events. They also watch for stomach upset, which shows up fast if the dose is too high. Nobody in these studies recommends random self-experimentation. For most of us, healthy eating and hydration do far more for performance and recovery than any supplement.

Be Smart with Home Remedies

Baking soda delivers quick relief for occasional heartburn—every pharmacy stocks it for that reason. It does not cure chronic disease or fit as a daily habit. If your stomach burns every week, the right move is talking with a healthcare provider. Baking soda belongs more on the kitchen shelf than in your medicine cabinet. For most folks, sticking to simple, balanced meals and watching your salt intake pays off in ways no home remedy can touch.
