Berringa's 100% Australian Manuka Honey is an ultra-high strength, antibacterial manuka honey with a Methylglyoxal (MGO) reading of 900+. It contains natural enzymes and antioxidants and has a pre-biotic effect to boost immunity. It can be added to foods or drinks, but is more often taken by itself, orally or topically. This honey is unique to Australia and sourced from the Leptospermum polygalifolium bush, which grows in a variety of coastal habitats along the north coast of NSW, and Southern Queensland. The Methylglyoxal (MGO) readings of these manuka honeys, measures their antibacterial and antimicrobial activity. Research has shown that honeys with a strength over 100MGO can be used therapeutically. Antibacterial activity measurement of Manuka honey: UMF vs MGO Manuka honey comes packaged with antibacterial activity measurement labelled on the jar. In this case it is MGO 900+. These numbers can be confusing, because there are different measurement systems in use! MGO (or methylglyoxal) is a globally recognised measure of antibacterial activity. Berringa uses this proven measurement methodology to grade and verify the actual MGO activity levels for each batch using independent testing at NATA accredited laboratories. UMF (unique manuka factor) is another system of measurement for antibacterial activity. While most countries use MGO as the standard measurement, UMF is usually associated with some Manuka honey products from New Zealand. Not suitable for infants under 12 months
