Sodium bicarbonate is a salt that breaks down to form sodium and
bicarbonate in water. This makes a solution alkaline, meaning it's able to
neutralize acid. Sodium bicarbonate's ability to neutralize acid helps
treat conditions related to high acidity in bodily fluids, such as
indigestion, which is caused by too much acid in the stomach. People
commonly use sodium bicarbonate for indigestion. It is also used for
stomach ulcers, athletic performance, kidney damage, dental plaque, tooth
discoloration, and many other conditions, but there is no good scientific
evidence to support many of these uses.
