How MERILOG Works

MERILOG regulates glucose metabolism by lowering blood glucose levels through the stimulation of peripheral glucose uptake in skeletal muscle and fat. It further controls blood sugar by inhibiting the production of glucose within the liver. Beyond glucose regulation, the drug inhibits the breakdown of fats and proteins while simultaneously enhancing protein synthesis.
