Manuka Honey MGO Ratings Explained: A New Zealand Buyer's Guide

If you've ever stood in front of a shelf of Manuka honey trying to work out why one jar costs $30 and another costs $90, you're not alone. The numbers on the label — MGO 263, MGO 829, and so on — are the key to understanding what you're actually buying. Here's what they mean, in plain English.

## What Does MGO Mean?

MGO stands for methylglyoxal. It's the natural compound in Manuka honey responsible for its unique antibacterial properties — the thing that sets Manuka apart from ordinary honey.

The number after MGO tells you how much methylglyoxal is in the honey, measured in milligrams per kilogram. So MGO 263 means at least 263mg of methylglyoxal per kilo. MGO 829 means at least 829mg. The higher the number, the more potent the honey — and generally, the higher the price.

## MGO vs UMF: What's the Difference?

You'll also see some Manuka honey graded with a UMF number (Unique Manuka Factor). UMF is a broader certification system that measures several markers, while MGO measures methylglyoxal specifically.

As a rough guide, they line up like this:

- UMF 5+ is roughly MGO 83+
- UMF 10+ is roughly MGO 263+
- UMF 15+ is roughly MGO 514+
- UMF 20+ is roughly MGO 829+

Neither system is "better" — they're just different ways of measuring quality. What matters most is that the rating is genuine and independently verified.

## Which MGO Rating Should You Choose?

It depends on what you want it for:

- **Everyday use** (in tea, on toast, as a daily wellness habit): MGO 263+ is a great all-rounder — potent, affordable, and versatile.
- **Targeted wellness** (immune support, soothing a sore throat, higher potency): MGO 829+ delivers serious strength for when you want maximum benefit.

There's no need to buy the highest number available if you don't need it. A quality MGO 263+ is genuinely effective for most people's day-to-day use.

## The Question Nobody Asks: Is the Number Real?

Here's the part the industry doesn't love talking about. Manuka honey is one of the most counterfeited foods in the world — more is sold globally each year than New Zealand actually produces. That means the number on the label isn't always the number in the jar.

This is why independent lab testing matters more than the rating itself. A jar claiming MGO 800 means nothing without a certificate to back it up.

At Waka Gold, every batch is independently lab tested by Hill Laboratories. Our MGO 263+ tested at 510mg/kg. Our MGO 829+ tested at 881mg/kg. In other words, our honey doesn't just meet the label — it exceeds it. And we can prove it, because the certificate says so.

## How to Buy Manuka Honey With Confidence

When you're choosing Manuka honey, look for three things:

1. A clear MGO or UMF rating on the label
2. Evidence of independent lab testing (not just the brand's word)
3. Genuine New Zealand origin

Get those three right and you'll never overpay for a number that isn't real.
