CATEFERM™
Fermented Matcha Postbiotic Extract
Support your gut, liver, and metabolic health — from the inside out.
Not your average matcha.
You’ve seen matcha in lattes. You’ve read about antioxidants. But CateFerm™ is something entirely different.
This isn’t matcha powder you whisk into water. CateFerm™ is a fermented matcha postbiotic extract — meaning beneficial bacteria have already broken down the catechins, chlorophyll, and polyphenols into their most bioavailable, metabolically active forms before they even reach your gut.
The result is a precision postbiotic ingredient that works where standard matcha supplements simply can’t.

What Makes CateFerm™ Different
Traditional matcha gives you raw catechins (like EGCG). Your digestive system then has to convert these into usable compounds — a process that depends heavily on the health of your existing gut microbiome.
Through controlled bacterial fermentation using food-grade cultures, we’ve transformed premium Japanese matcha into something far more targeted:
• Postbiotic catechin metabolites in immediately recognisable form
• Enhanced polyphenol bioavailability (10–15× greater than standard matcha)
• Prebiotic-like compounds that selectively nourish beneficial gut bacteria
• Bioactive metabolites that support a balanced gut environment
Why Fermentation Changes Everything
Fermentation pre-converts the active compounds in matcha, bypassing the digestive conversion step that many people — especially those with compromised gut function — struggle with. You get the metabolites your cells need, not just the raw materials.

What CateFerm™ Supports
CateFerm™ is formulated to support normal physiological function across several interconnected body systems. It is a food supplement, not a medicine.
✓ Normal liver function and healthy enzyme levels within the normal range
✓ A balanced gut microbiome and healthy microbial diversity
✓ Normal gut barrier integrity and digestive comfort
✓ Healthy inflammatory balance within the normal physiological range
✓ Mitochondrial function and normal energy-yielding metabolism
✓ Normal metabolic processes including healthy blood glucose management
✓ Cognitive clarity and normal mood function
✓ Athletic performance support and normal recovery
✓ Healthy weight management as part of a balanced lifestyle
These statements refer to normal physiological function. CateFerm™ is not intended to diagnose, treat, cure, or prevent any disease. If you have a medical condition, consult your healthcare provider before use.
The Gut-Liver Connection
Your liver and gut are in constant two-way communication via the gut-liver axis. What happens in your gut doesn’t stay in your gut — it directly influences your liver’s workload, your metabolic efficiency, and your systemic inflammatory balance.
CateFerm™ supports this axis through two complementary mechanisms:
1. Direct Polyphenol Activity
• Catechin metabolites that support normal fat metabolism in the liver
• Activation of AMPK pathways — a key regulator of cellular energy balance
• Antioxidant activity supporting normal cellular protection
• Chlorophyll derivatives that support normal liver detoxification pathways
2. Microbiome-Mediated Support
• Fermented polyphenols that reach the colon and selectively nourish beneficial bacteria
• Support for Akkermansia muciniphila, Faecalibacterium prausnitzii, and Roseburia spp.
• Normal gut barrier integrity via increased short-chain fatty acid (butyrate) production
• Reduced systemic burden from gut-derived compounds
Who CateFerm™ Is For
CateFerm™ is designed for health-conscious adults who want precision postbiotic nutrition, not generic antioxidant supplementation. It may be particularly relevant if you:
• Want to actively support liver health as part of a longevity-focused lifestyle
• Are interested in gut microbiome optimisation beyond standard probiotic supplementation
• Have tried probiotics without achieving the results you wanted
• Are focused on metabolic health, energy, and maintaining healthy body composition
• Value mitochondrial optimisation and sustained cognitive clarity
• Are an athlete seeking metabolic efficiency and recovery support
• Have a family history of metabolic or liver-related health concerns
• Want to take a proactive, evidence-informed approach to long-term health
A Note for Those Navigating Complex Health Situations
CateFerm™ is a food supplement, not a treatment. If you are managing a diagnosed health condition, are undergoing medical treatment, or have specific clinical concerns, please consult your healthcare provider or a registered nutritional therapist before starting any new supplement. Our team of qualified practitioners is also available for personalised guidance.

Frequently Asked Questions
How is this different from regular matcha powder?
Regular matcha provides raw catechins that your digestive system must convert into usable metabolites. CateFerm™ delivers those metabolites directly as postbiotics, ensuring bioavailability regardless of your current gut function. It’s also caffeine-free and more targeted in its activity.
Does CateFerm™ contain caffeine?
No. The fermentation process removes caffeine while concentrating the beneficial polyphenol metabolites.
I have a liver or digestive concern. Can I take this?
CateFerm™ is a food supplement designed to support normal physiological function. It is not intended to treat, diagnose, or cure any medical condition. If you have a diagnosed condition, please consult your healthcare provider before starting any new supplement.
How long until I notice a difference?
Microbiome changes typically begin within 4–6 weeks of consistent daily use. Energy and cognitive clarity improvements may be noticed sooner, within 2–3 weeks for some individuals. Consistent, long-term use yields the most meaningful results.
Will this help with weight management?
CateFerm™ is not a weight-loss supplement. However, it supports normal metabolic processes and satiety signalling, which may contribute to healthy weight management as part of a balanced diet and lifestyle.
Can I take this alongside probiotics?
Yes. CateFerm™ works synergistically with probiotics by helping to create a more favourable gut environment for beneficial bacteria to thrive.
Is this suitable for long-term use?
Yes. CateFerm™ is derived from fermented food-grade compounds with an excellent tolerability profile and is designed for continuous daily use.
Is this suitable for vegans?
Yes. CateFerm™ is 100% vegan, non-GMO, and gluten-free.
