GI: 46. Tested by the University of Sydney.
Jarrah honey is fructose-dominant by composition. That is what produces a measured glycemic index of 46. The number is real. The research is real. Here is the proof.
- 46 Glycemic Index
- TA50+ Analytica NZ Graded
- 100% Batch-Tested
University of Sydney - SUGiRS
The glycemic index of Jarrah Platinum TA50+ was measured by the University of Sydney's Glycemic Index Research Service (SUGiRS) — the institution that developed the glycemic index scale and the accrediting body for low GI certification in Australia. Result: GI 46.
🔒The original SUGiRS test certificate contains proprietary testing methodology and is treated as confidential documentation. It is not published online. However, the result is independently verifiable: the University of Sydney maintains a publicly searchable glycemic index database at glycemicindex.com - search for "Jarrah honey" to find and confirm the GI listing directly.
Analytica NZ - TA Grading
Analytica Laboratories New Zealand is an internationally recognised independent testing laboratory. They independently measured and graded Jarrah Platinum TA50+ for total antimicrobial activity, confirming the TA50+ rating printed on every jar.
Analytica NZ is the same laboratory used to assess antimicrobial strength in some of the world's leading Manuka honey producers. This is a third-party result from a globally credible institution — not an in-house test.
HACCP / SafeFood - Food Safety
HACCP (Hazard Analysis and Critical Control Points) is the internationally recognised food safety management standard. SafeFood certification confirms that Forest Fresh Honey's production, handling, and packaging processes meet the mandatory food safety requirements for export-grade product.
This certification covers the full production chain, from harvest to jar, ensuring every batch meets the same rigorous standard.
ChemCentre - Composition Testing
ChemCentre is a Western Australian government-owned scientific services provider. They independently tested Jarrah Platinum TA50+ for full sugar composition, confirming the fructose-dominant profile that underpins the lower GI value, as well as moisture content and raw chemical composition.
This is the testing that confirms what is actually in the jar, not just what is claimed on the label.
QSI - Quality, Bioactivity & Authenticity
Quality Services International (QSI) conducted independent testing for product quality, bioactivity, and authenticity. Authenticity testing confirms this is genuinely single-origin Western Australian Jarrah honey with no adulteration.
In a category where 1 in 5 commercial honeys has been found to contain undisclosed additions, independent authenticity verification is a meaningful proof point.
BQUAL - Quality Assurance
BQUAL quality assurance certification covers production standards and quality management processes across the Forest Fresh Honey operation. This certification provides independent third-party verification that quality controls are applied consistently across every batch.
Great Taste Award 2024
The Great Taste Award is judged by the Guild of Fine Food in the United Kingdom - one of the most respected food and drink awards in the world. Forest Fresh Honey's Jarrah Platinum TA50+ received recognition at the 2024 awards, evaluated blind by a panel of over 500 food industry experts.
This is a taste and quality endorsement from a world-class international panel, independent of the brand.
Asian Apiculture Association
The Asian Apiculture Association Award recognises excellence in beekeeping practice, honey quality, and industry contribution across the Asia-Pacific region. This recognition reflects the quality of Forest Fresh Honey's harvesting standards and the exceptional bioactivity of Western Australian Jarrah honey.

What Makes Jarrah Honey Different From Every Honey You Have Tried
Why most honey raises blood sugar quickly. Why Jarrah doesn't.
The glycemic index measures how quickly a food raises blood glucose levels. Regular honey typically registers between GI 55 and 65. The reason is straightforward: most honey is glucose-dominant. Glucose absorbs rapidly into the bloodstream.
Jarrah honey is different at the molecular level. Its natural composition is fructose-dominant. Fructose is metabolised differently by the body — it is absorbed more slowly, which is reflected in the independently measured GI value of 46.
This is not a claim. It is a measurement from the University of Sydney.
The University of Sydney tested it. Here is what they found.
The Glycemic Index Research Service (SUGiRS) at the University of Sydney is the institution that developed the glycemic index scale. It is the accrediting body for low GI certification in Australia.
Forest Fresh Honey's Jarrah Platinum TA50+ was tested through SUGiRS. The measured result: GI 46.
Low GI is classified as 55 or below. Jarrah Platinum TA50+ sits at 46. That is not close to the threshold. It is 16% below it.
What the labels don't tell you about honey and glycemic index.
The glycemic index of honey is not printed on most labels. And GI varies significantly across honey types. Research records honey GI values ranging from 32 to 85 depending on variety, origin, and composition.
Most commercial honey has never been tested for GI by an accredited institution. Some honey labelled as "low GI" has no independent test result behind the claim.
Forest Fresh Honey has the SUGiRS test result. The number is 46. Not a range. A number.
The number that changes the conversation.
For people who track nutrition, a GI number is a decision-making tool. Not a promise. Not a health claim. A measurement that lets you make an informed choice.
GI values describe how quickly each food raises blood glucose levels relative to a reference food. Forest Fresh Honey Jarrah Platinum TA50+: GI 46. University of Sydney tested.

GI Reference
For people who thought honey was off the table.
For years, many people managing blood sugar have removed honey from their diets entirely. Usually on the advice of a GP or dietitian who correctly said: regular honey raises blood glucose.
That advice was not wrong. Regular honey does. GI 55 to 65.
But not all honey is the same. And not all honey has been independently tested to prove it. Jarrah honey at GI 46 is a different product. The data exists. The institution that produced it is the University of Sydney.
This is the honey for people who read before they eat.
For People Who Actually Checked The Label.
"The TA50 is a favourite, especially since it's Low GI certified."
"The Jarrah Platinum TA50+ is a very delicious honey. The low GI index is also very beneficial."
"So much nicer than Manuka honey with a caramelised maple syrup flavour and low GI as well. Highly recommended."
"Very pleased with the Jarrah Platinum Honey I ordered - have it on cereal instead of sugar, also on toast."
"Very pleasant communication from the owners, and came with certification reports. Will buy again!"
"Never again will I be buying supermarket honey, with its secret added sugars, again."
Jarrah honey is fructose-dominant by composition. That is what produces a measured glycemic index of 46. The number is real. The research is real. Here is the proof.

What does a glycemic index of 46 actually mean?
What does a glycemic index of 46 actually mean?
The glycemic index measures how quickly a food raises blood glucose levels. A GI of 46 means Jarrah Platinum TA50+ raises blood glucose more slowly than regular honey (GI 55-65) or table sugar (GI 65). Low GI is classified as 55 or below. This is a nutrition content measurement — not a health claim and not medical advice.
How was the GI tested, and by whom?
How was the GI tested, and by whom?
The glycemic index of Jarrah Platinum TA50+ was measured by the University of Sydney's Glycemic Index Research Service (SUGiRS), the institution that developed the GI scale and the accrediting body for low GI certification in Australia. The measured result is GI 46.

GI 46 is a nutrition content measurement. It tells you how quickly the food raises blood glucose relative to a reference food. If you are managing blood glucose under medical supervision, we recommend discussing any dietary changes with your healthcare provider. This product is not intended to diagnose, treat, cure or prevent any disease.
My GP told me to avoid honey. What should I say to them?
My GP told me to avoid honey. What should I say to them?
Your GP was correct about regular honey. Jarrah honey has been independently measured at GI 46 by the University of Sydney. Whether this is appropriate for your specific situation is a question for your healthcare provider.
I have seen low GI on honey labels before and it was not backed by testing. How is this different?
I have seen low GI on honey labels before and it was not backed by testing. How is this different?
The difference is the testing institution. Forest Fresh Honey's GI of 46 was measured by the University of Sydney's Glycemic Index Research Service (SUGiRS), the same institution that developed the glycemic index scale. This is not a self-reported claim. It is a measured result from an accredited testing body with documented methodology.
Why does Jarrah Platinum TA50+ cost more than supermarket honey?
Why does Jarrah Platinum TA50+ cost more than supermarket honey?
Three reasons. Jarrah trees flower irregularly, typically every two to four years, making supply genuinely limited. Every batch is independently graded by Analytica NZ for TA activity and tested by ChemCentre for composition. The glycemic index was measured through the University of Sydney. These are not costs that supermarket honey producers typically carry.
