MGO, or methylglyoxal, is a natural compound found in various foods, particularly in honey, especially Manuka honey. It is known for its antibacterial properties and is often studied for its potential health benefits. MGO levels can vary significantly depending on the source and processing of the honey. In addition to its presence in honey, MGO is also produced in the body as a byproduct of metabolism. While it has some beneficial effects, high levels of MGO can be harmful and are associated with certain health issues. Research continues to explore its role in both food and human health.
