                                The average jar of regular honey contains very low or undetectable levels of Methylglyoxal (MGO), but a jar of Manuka honey with a 500 MGO rating indicates a very high concentration of this potent antibacterial compound. This number provides a clear, scientifically-backed measure of the honey's strength and effectiveness for targeted health uses.
