US Patent 11304971 Metformin compositions and methods for treatment of diabetes

The invention provides compositions and methods to treat diabetes with improved formulations in which metformin is combined with at least three antioxidants that contain a stabilizing heteroatom adjacent to a saturated carbon and which help maintain a balance between antioxidant and pro-oxidant properties. The antioxidants include at least the combination of taurine, citrulline and methylcobalamin, and optionally include melatonin. The composition provides management of blood glucose levels comparable to metformin in the same dose without antioxidants, without the phenomenon of undermining metformin performance that is commonly observed in the presence of co-administered antioxidants.
