How it works

Most gut don’t need more bacteria-they need address a leaky gut lining. Pouring in probiotics is like filling a leaking bucket.

Our formula works at the root. It seals your gut lining with L-Glutamine and Zinc to stop irritation and bloating at the root while targeting the gut brain axis for more time spent in rest and digest.

Our formula contains proven ingredients to allow your own unique good bacteria to grow naturally, giving you a balanced gut that’s 100% yours.

How to use

Take two capsules in the morning and two at night.

While many brands opt for a single-capsule "convenience dose," the science of the gut requires a more sophisticated approach. Your gut lining turns over ever 72-120hrs.

The FixBIOME Difference: 120 Capsules vs. 30 or 60

Most companies provide 30 or 60 capsules and call it a "month supply" to save on costs. We provide 120 capsules per bottle. We do this because your body deserves the full therapeutic dosage identified in clinical research.
By dosing morning and night, we ensure your gut-brain axis is supported 24/7, matching your body's natural biological rhythms rather than taking the easy way out.

We prioritise your results over our manufacturing costs. You aren't just getting a bottle; you're getting a complete 30-day clinical protocol.

Who it’s for

Anyone wanting to tackle bloating, improve their gut health and regulate their gut brain axis. Suitable for Men and Women.

Most people begin to notice digestive and mood changes within a few days of starting Gut Fix, although this varies between individuals.

Longterm use allows you to strengthen your gut with every cellular turnover cycle leading to a less reactive more resilient gut.

Who can benefit from taking Gut Fix?

Gut Fix suitable for adults looking to support healthy digestive function and mental wellbeing.

It helps relieve gut irregularity, ease abdominal bloating and digestive irritation, reduce bloating, and support the body's gut brain signalling - for improved time spent in rest and digest.

Why is this great value?

Clinical-Grade Selection: We don't just use ingredients that are "supported by evidence"; we select specific botanical extracts and compounds at the exact concentrations shown to be effective in clinical research.

Purity & Bioavailability: A product is only as good as what your body can actually absorb. We prioritize high-stability ingredients and rigorous purity testing to ensure every dose is free from fillers and contaminants that could irritate a sensitive gut.

Targeted Efficacy: Our formulas are engineered for stability. From sourcing to encapsulation, we ensure that the active ingredients remain potent and effective by the time they reach your digestive tract.

Beyond Compliance: We go beyond standard regulatory requirements. Our internal purity and stability benchmarks are significantly stricter because we know our customers have complex digestive needs that require a higher standard of care.

What lab testing do you do?

All our ingredients are third party tested for quality and purity.

Each product is subject to world-class purity and stability testing to ensure the amounts of active ingredients on the label remain active throughout their shelf life.

All FixBIOME® products are made in in a TGA and FDA certified facilities.

Each product is thoroughly tested for heavy metal, contaminant, and microbiological analysis by third party, TGA-registered, ISO/IEC-certified laboratories.

Why does FixBIOME provide 120 capsules while other brands provide 30 or 60?

Most brands prioritize their profit margins by "pixie-dusting" ingredients putting just enough on the label to make a claim, but not enough to make a difference. We do things differently.

  • Clinical-Grade Potency: We don't just use "studied" ingredients; we use the exact concentrations proven to work in human clinical trials. To get that therapeutic dose into your system, you need more capsules.
  • Bio-Availability Over Fillers: A supplement is worthless if your body can't absorb it. We use high-stability, pure extracts—free from the cheap fillers that usually irritate sensitive guts—to ensure the active compounds actually reach your bloodstream.
  • The 24/7 Repair Cycle: Your gut never sleeps. By providing 120 capsules, we allow for a morning and night protocol that maintains "steady-state" levels in your system, supporting your body’s natural cellular turnover and signalling 24 hours a day.

Are these ingredients clinically studied?

Yes. We don't believe in "pixie-dusting" or guesswork. Every active ingredient in Gut Brain Axis has been selected based on rigorous, peer-reviewed clinical research.

We go beyond just using "proven" ingredients; we include them at the exact therapeutic dosages used in those studies to ensure they actually work. By prioritizing clinical-grade extracts and high bioavailability, we ensure that your "second brain" receives the precise support needed to regulate mood, focus, and digestive harmony.

With FixBIOME, you aren't just buying a supplement—you’re investing in a formula backed by human clinical data.

Is it vegan and allergen-free?

Absolutely. Gut Brain Axis is a 100% vegan formula, engineered to be ultra-clean for those with heightened sensitivities. It is strictly free from gluten, dairy, fish, tree nuts, and sulphites. Furthermore, it is formulated to be FODMAP-friendly, ensuring it supports the enteric nervous system without triggering digestive distress.
