Metformin is a natural supplement that can be used to treat and prevent high levels of blood sugar that is caused by type 2 diabetes. Metformin works to reduce the level of sugar that is released into the blood from the liver. It also works to help the body respond better to insulin.
Metformin can also be used to help women with PCOS (Polycystic Ovary Syndrome) by lowering blood sugar levels and insulin which can then help stimulate ovulation.
