how much metformin a day?

Answer 1

Whatever your doctor recommends for you.

For some people, 500 mg per day is enough but the dosage can be as high as 2,000 mg per day.  It is usually taken in two to four doses.  Usually before meals.

It is a prescription - so you need a doctor's advice to get it and take it.
