A long-established oral medication that lowers the glucose your liver makes and improves how your body responds to insulin — supporting metabolic health and weight as part of a broader plan. Prescribed online, shipped from U.S. pharmacies.
Metformin is an oral insulin-sensitizing medication (a biguanide) that lowers the amount of glucose your liver produces and improves how effectively your body uses insulin. Taken daily, it supports metabolic health and can support weight management as part of a broader plan that includes nutrition and activity.

One of the most widely used and well-characterized metabolic medications.
