Manuka Honey MGO 600+ | NPA 16+

Methyglyoxal (MGO)

MGO strength refers to the independently lab-verified methylglyoxal (mg/kg) in our Manuka honey. Higher MGO is associated with stronger antibacterial activity.

What it is, and why it matters

MGO600+ is a high-MGO pure, raw and potent authentic Australian Manuka Honey. Manuka nectar is naturally rich in DHA (dihydroxyacetone), which slowly converts to MGO (methylglyoxal) as the honey matures. We store every batch under controlled temperatures, then release it when the DHA:MGO balance delivers great flavour and a reliably lab-verified MGO level. Research shows that the more MGO a Manuka honey contains, the stronger its non-peroxide (NPA) antibacterial activity when used or consumed.

What the ‘+’ means

The + is a minimum. MGO600+ means the honey contains at least 600 mg/kg of methylglyoxal. Batches typically test 5% or more above that figure.

Take one teaspoon, morning and/or evening, allowing it to sit in the mouth before swallowing. Alternatively, dilute in warm (not hot) water or a little vinegar and consume as preferred. Manuka honey has been the subject of extensive research over many years; use according to your needs and consult a healthcare professional for individual guidance.

Who chooses 600+

Manuka buyers who want stronger MGO, this is the one to always have at home - a trusted provenance, and certified laboratory testing.

Taste & aroma

Bold, deep amber, pronounced resin and spice, and a satisfying, lingering Manuka finish.

Australian Manuka

Gather By honey is sourced from healthy honeybees foraging on biodiverse Australian Leptospermum plants, grown in partnership with Australian farmers and Traditional Owners to produce naturally pure, raw and potent Manuka honey.

Authenticity & assurance

Every jar is independently MGO-tested, track-and-trace enabled, and packed in Ballina, NSW under HACCP/B-QUAL systems. We’re an award-winning Australian producer, and a COA is available on request.

Each batch independently tested & verified

Australian researchers from University of Sunshine Coast (USC) including teams studying the chemistry of Leptospermum honeys have mapped markers that help authenticate and profile Manuka. The USC provides independently verified evidence of each batch of honey that is released to the public.

AMHA Mark of Authenticity — why it matters

Gather By is a founding member of the Australian Manuka Honey Association (AMHA). This Mark of Authenticity means the honey was produced in Australia from Leptospermum, and independently tested by an approved lab for the key markers of authentic Australian Manuka. The Mark also requires traceability through the supply chain. In short: it’s your quick way to trust what’s in the jar and to compare strength by a verified MGO number.

All our honey is dispatched from our warehouse runny and fresh, however, crystallisation can happen eventually to pure and raw honey.

There are things you can do to prevent or prolong this process though, which includes storing the honey out of direct sunlight, between 10 - 22°C, and keeping the lid tight to avoid moisture getting in.

Because we avoid excessive heat, some jars may crystallise naturally over time. Many customers love the creamy texture; if you prefer it runny, stand the jar in warm (not hot) water and stir gently.

Manuka honey has been studied for decades across laboratory, clinical, and health-system settings.

These describe the research landscape on honey/Manuka across each area.

Wound & skin care (medical-grade dressings)

• Big evidence reviews find that honey dressings can speed healing for partial-thickness burns and some infected post-op wounds. Cochrane+1
• UK summaries on advanced/antimicrobial dressings (includes honey) discuss where they may fit in chronic wound care. NICE+1

Sore throat & cough (URTI self-care)

• UK NICE lists honey as a first-line self-care option for acute cough in people over 1 year, based on trials showing small symptom improvements. NICE
• A BMJ Evidence-Based Medicine meta-analysis reports honey improved URTI symptoms versus usual care; a Cochrane review supports benefit for children’s acute cough. BMJ Evidence-Based Medicine+1

Oral health (plaque/gingivitis)

• A pilot RCT using a chewable Manuka found reductions in plaque and gingival bleeding vs control over 21 days. ハイマート
• A randomised field trial in schoolchildren showed Manuka-based mouthwash reduced plaque and gingival scores Europe PMC

Gut health (prebiotic)

• Dr Patricia L. Conway led an Australian (RIRDC/AgriFutures) report concluding some Australian honeys show prebiotic properties—supporting beneficial gut microbes. AgriFutures Australia
• Conway co-authored overviews highlighting prebiotic potential (lab, animal and early human work) and pathways for future clinical studies. APIMONDIA+1

Immunity (immunomodulation)

• Reviews summarise immunomodulatory and anti-inflammatory effects of honey/bee-product polyphenols; human evidence exists but is heterogeneous and protocol-dependent. MDPI+1

Energy / exercise fueling

• In a randomised crossover cycling trial, honey gel performed similarly to dextrose for a 64-km time-trial. Europe PMC
• Narrative/systematic reviews conclude honey can serve as a viable carbohydrate source in some endurance protocols. ScienceDirect

Strep & MRSA:

• Manuka has lab-demonstrated activity against Streptococcus pyogenes and MRSA, including biofilms. In healthcare, sterile medical-grade honey dressings are used for certain wounds. Europe PMC+2Wounds UK+2

Hospitals use sterile, regulated medical-grade honey dressings supported by clinical evidence and device approvals. Our jars are food: independently MGO-tested and batch-traceable, but not intended to treat diseases or replace medical care.

Important: Not suitable for infants under 12 months

Honey can naturally contain spores of Clostridium botulinum. Infants under 12 months do not yet have mature gut defences to prevent these spores from germinating and producing toxin (infant botulism). Heating or pasteurising honey does not reliably eliminate spores, so please avoid giving honey—or foods containing honey—to babies under one year. From 12 months onward, honey is generally safe for healthy children and adults.

Allergen information
