Baking Soda Under the Tongue: Fact, Fad, or Something Else?

What People Try With Baking Soda

People have been reaching for baking soda for decades, mostly as a leavening agent in the kitchen or a home remedy for minor heartburn. Lately, a claim popped up on social media suggesting that holding a bit of baking soda under the tongue can balance body pH, boost energy, relieve mouth ulcers, or magically freshen breath. Trends like this spread fast, especially on platforms promising simple life hacks.

How Baking Soda Actually Works

Baking soda, or sodium bicarbonate, does one thing really well: it neutralizes acids. In the body, this could mean it temporarily lowers stomach acidity. Hospitals rarely use it intravenously for people with severe acidosis, but that’s tightly monitored by professionals. I’ve learned from experience with home remedies that too much enthusiasm for a so-called shortcut can go sideways. Overusing baking soda can cause more harm than good—think elevated sodium levels, muscle spasms, and a real mess for people with high blood pressure or kidney issues.

What Happens Under the Tongue

Some users believe that putting baking soda under the tongue sends it straight into the bloodstream and speeds up its benefits. The science doesn’t back this up. While some medications, like nitroglycerin, absorb quickly under the tongue, sodium bicarbonate doesn’t work that way. Most of it stays on the surface, only mixing with saliva and eventually getting swallowed. The mouth might taste bitter, and you won’t dodge its salty, gritty feel. There’s no evidence this trick gives you special pH-balancing powers or instant relief from fatigue.

What’s At Risk

Salt intake stands out as a concern. If you’re sensitive to sodium or have a pre-existing health condition, trying these fads could tip the balance in the wrong direction. I once met a man who swore baking soda would “alkalize” his body after a big night out, but he ended up feeling bloated and thirsty instead. Medical journals warn that regular extra sodium can overload the kidneys, throwing off fluid balance, and causing a spike in blood pressure. The side effects can stretch beyond one bad day to something much harder to fix. The American Heart Association frowns on excess sodium for a reason.

Better Ways to Achieve the Same Goals

There’s more effective, evidence-based ways to take care of oral health or improve energy. Hydration, for instance, plays a big role in oral comfort and energy levels. Moderating acidic foods helps mouth ulcers heal. Using a salt-water rinse (not swallowing it) soothes many oral irritations. Long-term, eating balanced meals and practicing regular physical activity support a healthy pH and boost energy much better than quick-fix hacks.

The internet will always churn out new tricks, but some old wisdom holds true: listen to science, talk with professionals, and avoid shortcuts that sound too good to be real. Most quick fixes wind up being less helpful than the effort to just take care of ourselves with proven habits.
