MGO 550+ Manuka Honey has a naturally occuring minimum of 100mg/kg methylgyoxal content which is responsible for the remarkable properties in Manuka Honey. Manuka Honey is collected from a plant that is unique to New Zealand – Leptospermum scoparium. The white flowers appear in spring and are much loved by the honey bees. Manuka flowers have a strong, aromatic fragrance and are full of the nectar which provides this dark, creamy honey. Methylglyoxal - the unique compound in Manuka Honey MGO Manuka Honey is labelled based on the minimum Methylglyoxal content (mg/kg) it contains.
