Manuka Honey: Origins, Benefits, and Understanding MGO & UMF Ratings

Introduction

Manuka honey is a unique type of honey produced primarily in New Zealand and parts of Australia. It is made by bees that pollinate the Manuka tree (Leptospermum scoparium). This honey is known worldwide for its powerful antibacterial, anti-inflammatory, and healing properties, making it one of the most sought‑after honeys in the world.

Where Manuka Honey Comes From

Manuka trees grow naturally in New Zealand’s untouched forests and coastal regions. The honey is harvested from bees that feed on the Manuka blossoms, which bloom for only a few weeks each year. This short blooming season and the unique chemistry of the plant contribute to Manuka honey’s rarity and high value.

Health Benefits of Manuka Honey

Manuka honey has several scientifically supported health benefits:

• Strong antibacterial and antimicrobial activity  

• Supports wound healing and tissue repair  

• Soothes sore throats and coughs  

• Helps with digestive health and acid reflux  

• Supports immune function  

• May improve skin conditions such as acne and eczema  

• Contains antioxidants that fight inflammation  

• Helps oral health by reducing harmful bacteria  

• Supports gut balance and may help with ulcers

What MGO Means

MGO stands for methylglyoxal, the key antibacterial compound that makes Manuka honey special. The number (e.g., MGO 570, MGO 829, MGO 1200) represents how many milligrams of methylglyoxal are found in every kilogram of honey.  

Higher MGO = stronger antibacterial activity.

Understanding UMF Ratings (16+, 20+, 25+)

UMF stands for Unique Manuka Factor. It is an independent quality rating that measures:

• MGO levels  

• Leptosperin (a signature marker proving authenticity)  

• DHA (a precursor to MGO)  

• Overall purity and potency  

Examples:  

• UMF 16+ ≈ high medicinal strength  

• UMF 20+ ≈ very high medicinal strength  

• UMF 25+ ≈ ultra‑premium medicinal strength  

Both MGO and UMF help confirm the honey’s purity and effectiveness.

Comparing MGO 570 (UMF 16+), MGO 829 (UMF 20+), and MGO 1200 (UMF 25+)

• MGO 570 / UMF 16+: Strong antibacterial strength, suitable for health maintenance, immunity, and moderate healing uses.  

• MGO 829 / UMF 20+: Very high strength; used for stronger immune support, digestive problems, and harsher bacterial infections.  

• MGO 1200 / UMF 25+: Extremely potent; used for medical‑grade healing, severe infections, and therapeutic use.  

Higher grades are typically more expensive and are usually taken in smaller daily amounts due to their potency.
