Sodium bicarbonate is a mildly alkaline salt widely used as a buffering agent, antacid component, and effervescent agent.

In pharmaceuticals and nutraceuticals, it is used in effervescent tablets, dispersible powders, and antacid formulations to generate CO2 and adjust pH.

In food applications, it serves as a leavening agent in baked goods and a mild cleaning and deodorizing component.

Its good safety profile, water solubility, and reactivity with acids make it a core functional excipient.
