Unique Mānuka Factor UMF™ – Quality Certification

The beauty of mānuka honey comes from a complex collection of natural compounds that we call the Unique Mānuka Factors (UMF™) – and you won’t find it anywhere but in authentic New Zealand mānuka honey.

UMF™ is the only quality and rating system that independently certifies the presence and quality of all factors that make New Zealand mānuka honey unique, ensuring you get honey that meets your needs. Check for the UMF™ quality mark on the front of pack when choosing your mānuka honey.

The Unique Mānuka Factor Honey Association (UMFHA) independently tests and certifies every batch from our 150+ members for four key factors that make the all-important UMF™ rating found on every jar of authentic mānuka honey. With the UMF™ rating, you can confidently choose the right option for you when investing in your health and wellness.

New Zealand Mānuka Honey

For almost a thousand years, the mānuka tree has been part of Māori healing traditions in Aotearoa New Zealand. In the last 25 years that researchers have truly begun to understand the benefits of one of the mānuka tree’s greatest gifts: mānuka honey.

The Unique Mānuka Factors in pure New Zealand mānuka honey stem from the unusual structure of the mānuka flower that produces the unique nectar at the heart of New Zealand mānuka honey. Continuing extensive international research is focused on the honey’s benefits, its incredible range of natural components, and understanding New Zealand’s unique mānuka tree and exceptional nectar.

Today, mānuka honey is used and enjoyed around the world for its exceptional natural health food properties.
