Metformin and berberine are great regulators. They won’t cure but will keep u happy. Metformin is officially a prescription drug BUT according to Life Extension.com (which is by far the leading science-based magazine and supplement maker in the world) have hundreds of pages and reference hundreds of studies demonstrating the health producing and life extending properties of metformin even though this Rx competes with their products!!
