What does it do?

Sodium bicarbonate is used as an antacid ingredient to relieve symptoms of peptic ulcers or heartburn. It helps reduce discomfort caused by excessive stomach acid and aids digestion.

Sodium bicarbonate reacts with the acidic environment in the stomach to neutralize it, thereby reducing the acidity of gastric acid. This helps alleviate pain and discomfort by reducing irritation of the stomach lining.
