Supporting your
microbiome.

Our microbial bacteria play a complex and essential role in how the body functions day to day.
The question is, are your daily habits supporting them?

What is the
microbiome?

Your microbiome is the collection of trillions of microorganisms living in and on your body, with the largest community in your gut. They play an active role in how your body functions day to day.

Building a microbiome-supporting routine isn’t always straightforward. Consistency with fibre-rich, minimally processed foods and fermented options tends to have the greatest impact over time.

How your gut communicates with your body

Your gut is constantly communicating with the rest of your body, influencing how different systems function.

Neural pathway

The gut and brain communicate via the nervous system, primarily through the vagus nerve, influencing stress, digestion, and internal balance.

Metabolic pathway

Compounds produced by gut bacteria enter the bloodstream and circulate throughout the body, influencing how different systems function.

Immune pathway

The microbiome interacts closely with the immune system, helping regulate its response and support gut barrier integrity.

What fuels your microbiome?

Your microbiome relies on more than one input. Prebiotics feed bacteria, probiotics introduce live cultures, and postbiotics are what they produce. Together, they support how your gut functions.

Prebiotics

Prebiotics are fibres that feed the beneficial bacteria already in your gut, helping them grow and stay active. Found in foods like onions, garlic, and whole grains.

They help to:
• Support beneficial bacteria
•Maintain balance in the gut

Probiotics

Probiotics are live bacteria that add to the existing population in your gut. Commonly found in fermented foods like yoghurt, kefir, sauerkraut and kimchi.

Their role is to:
• Introduce beneficial strains
• Support microbial diversity

Postbiotics

Postbiotics are the compounds produced when bacteria break down nutrients. These include substances like short-chain fatty acids involved in normal gut function.

They contribute to:
• The gut environment
• The activity of beneficial bacteria

Postbiotics

Isn't my diet
sufficient?

In an ideal world, your diet would cover everything your gut needs. In reality, maintaining that level of consistency every day isn’t always easy.
Maintaining optimal gut-supportive nutrition consistently through diet alone can be difficult.
A well-designed synbiotic and personalised nutritional support can help support your routine long term.

Potential Adjustment Effects:


Most of what you will notice are positive changes to your metabolism, immune system, energy, skin and overall wellbeing.
So don't panic if your body goes through an adjustment period as it adapts to our formulation.

Bright yellow wee: Totally harmless and normal for many, happens for the same reason as Berocca. This is due to our high vitamin B2 (riboflavin) content. Like all B vitamins, any excess is naturally excreted once your body has absorbed what it needs.

Digestive changes/bloating: No cause for concern. Our formula is potent and comprehensive — your body may take time to adjust to our live cultures, fibres, enzymes and micronutrients. Reducing your dose temporarily may help.

Mild digestive sensitivity: Some individuals may experience mild discomfort when first starting. This typically resolves quickly. Simply halve your dose until you have adjusted.Changes in digestive patterns: Temporary changes in frequency or consistency can occur as your system adapts.

Allergen information:

Contains: Gluten (Wheat).
