Metformin is a drug fda approved for type 2 diabetes.
Metformin belongs to the class of drugs known as biguanides. It works by helping to restore your body's proper response to the insulin you naturally produce, and by decreasing the amount of sugar that your liver makes and that your stomach/intestines absorb.
Off label it's used for PCOS, non-alchoholic fatty liver, premature puberty and gestational diabetes.
