Baking soda, also known as sodium bicarbonate, has long been a staple in kitchens for baking, cleaning, and even first-aid. But in natural health traditions, it has also been explored for its effects inside the body. One of the more unusual practices involves placing a small amount of baking soda under the tongue.

While this isn’t a mainstream medical recommendation, older generations often experimented with baking soda as a quick remedy for acid balance, digestion, and energy support. Some benefits can be explained by simple science: baking soda is alkaline, meaning it can neutralize acids and influence how the body manages pH levels.
So, what might actually happen when seniors try this?
1. Rapid Acid Neutralization
When placed under the tongue, baking soda is absorbed more quickly into the bloodstream. This can help neutralize excess stomach acid and may bring temporary relief from heartburn or indigestion.
Possible benefit:
- Relief from burning sensation in the chest
- Calmer stomach after heavy meals
2. Energy and Performance Support
Some studies in athletes show that baking soda reduces lactic acid buildup, which is what causes muscle fatigue. While seniors are not typically taking it for sports, the same principle may help with:

- Reduced muscle cramps during activity
- A small boost in endurance for walking or exercise
3. Kidney Function Support
Doctors sometimes use sodium bicarbonate in controlled doses for patients with chronic kidney disease to help balance blood acidity. This practice can support circulation and reduce strain on kidneys.
Note: This should only be done under medical supervision.
4. Oral Health Freshness
Baking soda naturally reduces bacteria in the mouth and neutralizes odors. A small amount under the tongue may leave the mouth feeling fresher.
Possible benefit:
- Temporary bad breath relief
- A cleaner, alkaline oral environment
5. Blood Pressure and Sodium Considerations
Since baking soda is a sodium compound, it can raise sodium levels in the body. For seniors with high blood pressure or heart disease, this may be risky if overused.

Possible risk:
- Increased blood pressure
- Fluid retention if taken in excess
Quick Reference Table
| Effect | Why It Happens | Helpful For Seniors? |
|---|---|---|
| Neutralizes stomach acid | Alkaline pH balance | May relieve indigestion |
| Boosts physical endurance | Buffers lactic acid buildup | Supports mild exercise activity |
| Freshens breath | Reduces oral bacteria | Improves confidence & hygiene |
| Kidney support (medically) | Balances blood acidity | Only with doctor’s supervision |
| Sodium load | Raises sodium levels | Caution with BP or heart issues |
How Seniors Can Use Baking Soda Safely
- Start tiny: Just a pinch under the tongue—never more than ¼ teaspoon in a day.
- Not daily: Use only occasionally for specific symptoms (like indigestion).
- Avoid if on sodium restrictions: Anyone with high blood pressure, kidney disease, or heart problems should avoid self-experimentation.
- Safer alternatives: For acid relief, sipping water with lemon or chamomile tea may be gentler.
Case Example: Mr. Carter, Age 68

Mr. Carter often had late-night heartburn. He tried a pinch of baking soda under the tongue and noticed quick relief within minutes. However, after his doctor explained the sodium risks, he switched to drinking warm water with ginger tea instead. This helped him manage symptoms without affecting his blood pressure.
Conclusion and FAQs
Does baking soda under the tongue cure disease?
No. It can temporarily ease certain symptoms, but it does not treat underlying conditions.
Is it safe for everyone over 50?
Not necessarily. Seniors with heart disease, high blood pressure, or kidney problems should avoid it unless directed by a doctor.
How fast does it work?
Indigestion relief can be almost immediate, but long-term health requires consistent lifestyle and medical care.
