Traditional, valuable Manuka honey The Manuka honey MGO 400+ from Manuka Health in New Zealand is a flower honey that is produced by bees from the nectar of the New Zealand South Sea myrtle. Manuka honey has been traditionally used by the indigenous people of New Zealand for centuries. The special feature compared to other honeys is the certified methylglyoxal content (MGO), a naturally occurring, valuable compound. One kilo of Manuka honey MGO 400+ already contains 400 mg of this scientifically proven ingredient. Manuka Health honey is tested for its natural methylglyoxal content as well as its purity and quality. Manuka honeys are also characterized by a pleasant, slightly bitter taste and a smooth, velvety melting texture. Application: Manuka honey can be enjoyed pure or used in a hot drink, as MGO is largely insensitive to heat.
