Baking soda water is a straightforward mixture that may help with digestion and acid reflux

Baking soda is a base, which means it can neutralize stomach acid. When you mix a small amount of baking soda with water and drink it, the mixture can temporarily raise the pH level in your stomach. For people dealing with heartburn or indigestion after a meal, this neutralizing effect often brings relief within minutes.

The effect is temporary — your stomach will produce more acid within an hour or two — but for occasional discomfort, many people find it works faster than waiting for other remedies to kick in. It is not a long-term solution for acid reflux, and it is not a replacement for medical treatment if you have chronic heartburn.

Key Takeaways

  • Baking soda water neutralizes stomach acid and may relieve heartburn or indigestion within minutes of drinking it.
  • A typical dose is one-half teaspoon of baking soda dissolved in four to eight ounces of water, taken once or twice a day as needed.
  • The relief is temporary because your stomach continues to produce acid after the baking soda is absorbed.
  • Drinking baking soda water regularly or in large amounts can cause side effects like bloating, nausea, and electrolyte imbalances.
  • People with high blood pressure, kidney disease, or those taking certain medications should talk to a doctor before using baking soda water.

How much baking soda to use and when to drink it

The standard dose for occasional heartburn is one-half teaspoon of baking soda stirred into four to eight ounces of water. Drink it slowly, and you should feel relief within 15 to 30 minutes. You can repeat this once or twice a day if needed, but not more than three times daily.

Timing matters. Drink baking soda water after a meal when you feel discomfort starting, rather than before eating. Taking it on an empty stomach is less effective because there is less acid to neutralize. If you find yourself reaching for baking soda water more than a few times a week, that is a sign to see a doctor — frequent heartburn points to a larger issue that baking soda alone will not fix.

Why baking soda water may cause bloating and gas

When baking soda mixes with stomach acid, it produces carbon dioxide gas. That gas can cause bloating, cramping, and flatulence, especially if you drink too much or drink it too quickly. Some people feel worse after baking soda water than they did before, which is why starting with a smaller amount — one-quarter teaspoon — makes sense if you have never tried it.

The bloating usually passes within an hour, but if it is severe or happens every time you drink it, baking soda water is not the right choice for you. Other antacids like calcium carbonate (Tums) or magnesium hydroxide (Milk of Magnesia) do not produce gas and may be gentler on your stomach.

Who should not drink baking soda water

If you have high blood pressure, baking soda water is not a good choice. Baking soda is sodium, and regular use can raise your sodium intake to unhealthy levels. People with kidney disease, heart disease, or liver disease should also avoid it because their bodies cannot regulate sodium the way a healthy body does.

If you take medications — especially diuretics, certain antibiotics, or blood pressure drugs — talk to a doctor or pharmacist before using baking soda water. Baking soda can interfere with how your body absorbs some medications and can change the balance of electrolytes in your blood. Pregnant women should check with their doctor first as well.

The difference between baking soda water and other antacids

Baking soda works fast because it is a base that when ready neutralizes acid. Over-the-counter antacids like Tums (calcium carbonate) and Rolaids (calcium carbonate plus magnesium hydroxide) work the same way but often include other ingredients that reduce gas production. Antacids like Pepto-Bismol work differently — they coat the stomach lining rather than neutralizing acid.

H2 blockers like famotidine (Pepcid) and proton pump inhibitors like omeprazole (Prilosec) take longer to work — 30 minutes to an hour — but they reduce the amount of acid your stomach produces rather than just neutralizing what is already there. For one-time heartburn, baking soda water is cheaper and faster. For frequent heartburn, a doctor may recommend an H2 blocker or proton pump inhibitor instead.

What to mix with baking soda water for better taste

Plain baking soda water tastes salty and slightly bitter. A squeeze of fresh lemon juice or lime juice makes it more palatable and adds flavor without changing how it works. Some people add a small amount of honey or a splash of apple juice, though adding sugar may slow down how quickly the baking soda reaches your stomach.

Avoid mixing baking soda water with milk or dairy products right away — the combination can cause excessive gas. If you want to add flavor, keep it straightforward: water, baking soda, and citrus juice is the most straightforward approach.

When to see a doctor instead of using baking soda water

If you have heartburn more than twice a week, or if it wakes you at night, baking soda water is a temporary fix, not a solution. Frequent heartburn can signal gastroesophageal reflux disease (GERD), a condition that needs medical treatment. A doctor can prescribe stronger medication and can rule out other causes like ulcers or infections.

If baking soda water does not relieve your symptoms within 30 minutes, or if your heartburn is accompanied by chest pain, difficulty swallowing, or vomiting, seek medical attention. These can be signs of something more serious than straightforward indigestion.

Frequently Asked Questions

Is baking soda water safe to drink every day?

No. Regular daily use can lead to electrolyte imbalances, high blood pressure, and metabolic alkalosis (when your blood becomes too alkaline). Baking soda water is meant for occasional use only. If you need heartburn relief daily, talk to a doctor about other options.

Can I use baking soda water for stomach pain that is not heartburn?

Baking soda water works only on acid-related discomfort. If your pain is from gas, bloating, constipation, or other causes, baking soda will not help and may make it worse. See a doctor to find out what is causing the pain.

How long does baking soda water take to work?

Most people feel relief within 15 to 30 minutes. The effect lasts about an hour before your stomach produces more acid. If you do not feel better within 30 minutes, the discomfort may not be heartburn.

Can I mix baking soda with other antacids?

No. Mixing baking soda with other antacids can cause dangerous electrolyte imbalances and excessive gas. Stick with one antacid at a time, and wait at least two hours before switching to a different one.

What is the difference between baking soda and baking powder?

Baking powder contains baking soda plus acid and other ingredients. Do not use baking powder as a substitute for baking soda in water — it will not work the same way and may cause stomach upset.
