Did you know you can use baking soda as a natural remedy for heartburn? For hundreds of years, people have used this product to reduce excess stomach acid, indigestion, and stomach upsets. However, it’s an ingredient that should be used with caution, and in moderate quantities.

Heartburn is a burning sensation that comes from your stomach and then moves toward the throat. Normally, when liquid or solid food enters the stomach, the ring of muscles at the bottom of the esophagus closes. This ring is known as the lower esophageal sphincter.

If it doesn’t close properly, the stomach contents can start to move back up toward the esophagus. This partially digested material can irritate the esophagus, causing heartburn and other symptoms in the upper digestive tract.

To combat this, there are a number of antacid medications available, including Tums, proton pump inhibitors, and over-the-counter medication.

However, some people use baking soda to combat heartburn. But does it actually work? We’ll tell you more below.

Can baking soda be used to combat heartburn?

Baking soda shouldn’t be considered a first-choice treatment for acid reflux. Although it’s attributed with effects as an antacid, its use should be done with moderation, in mild and sporadic cases.

To date, there’s no strong evidence to support the use of this ingredient as a treatment for acid reflux or for digestive problems. However, due to its composition and alkaline pH, it’s said to temporarily neutralize excess acid in the stomach.

In other words, it can be an adjuvant to soothe the sourness that comes from too much or irritating food, but it shouldn’t be an option in case of acid reflux. The latter should be addressed by your physician or gastroenterologist and should be addressed with other treatments.

Furthermore, baking soda may not be suitable for people who suffer from problems such as high blood pressure, liquid retention, or kidney problems. Thus, you should consult with your doctor before you try the baking soda treatment. It should also be accompanied by other preventative measures.

General tips to avoid heartburn

According to a publication in Clinical Gastroenterology and Hepatology, some lifestyle changes can also help to control heartburn. This includes eating a lighter diet, free from foods that irritate the gastric mucosa, such as:

  • Carbonated drinks
  • Fatty or seasoned foods
  • Sauces
  • Alcohol
  • Caffeine
  • Chocolate
  • Citrus fruits
  • Spicy food

Similarly, lifestyle changes such as losing weight, cutting out tobacco, and avoiding eating late at night can help. If possible, you could also try to raise the head of your bed to prevent nighttime heartburn.
