What Is Metformin?

Metformin is a biguanide medication that primarily works in the liver, muscles, and gut to improve how your body handles glucose and insulin. It’s one of the oldest, safest, and most affordable drugs in the diabetes world — and many people use it off-label at lower doses for metabolic and weight-related goals.

 

How Does Metformin Work?

Metformin helps your body use insulin more efficiently, stops the liver from dumping extra sugar, and gently nudges your metabolism toward fat burning and better energy use — without directly stimulating the nervous system.
