Researchers from Rutgers University discovered that adults who took metformin, a widely used generic medication for Type 2 diabetes, while exercising saw smaller improvements in blood sugar control, blood vessel function, and aerobic fitness than those who exercised without the drug.
Published last month in *The Journal of Clinical Endocrinology & Metabolism*, the findings add to growing evidence that although both metformin and exercise improve blood sugar control and heart health, combining them may dull some of exercise’s benefits.
