Baking soda, or sodium bicarbonate, helps heartburn, according to Mayo Clinic. The dosage for adults and adolescents is 1/2 teaspoon in 1 cup of water every 2 hours. Children should take the solution only under a doctor's supervision.
Baking soda reduces stomach acidity and keeps the acid from entering the esophagus, Healthline explains.
This is also a natural process. Sodium bicarbonate made in the pancreas helps the body deal with stomach acid.
Common side effects of using baking soda as an antacid are gas, nausea, thirst, headache and cramps, states Healthline. Baking soda should not be consumed by people on low-sodium diets. It also interacts with many medications, such as aspirin, barbiturates, diuretics, ampicillin and iron supplements, WebMD warns.
