Insumate® is a valuable and specific peptide extracted from bitter melon (Momordica charantia). it was discovered that this patented peptide sequence (mcIRBP-19) can activate insulin receptor activity and directly influence blood glucose regulation. The unique peptides of Insumate® have been decoded and found to be a small molecule peptide composed of 19 amino acids with the molecular weight of 2,162 daltons, endowing it with a high affinity to insulin receptor even after passing through stomach acid.
