How our digestive
system balance
affects our lives.
The human gut microbiome is a vast community of bacteria, fungi, viruses and other micro-organisms that together influence nutrient absorption, immune function and how we feel day to day.
A balanced intestinal ecosystem with abundant beneficial species and broad microbial diversity helps maintain a robust intestinal barrier, healthy short-chain fatty acid production and protection against harmful microbes.
Lifestyle factors such as diet, stress and poor sleep can disrupt this balance, allowing less-desirable bacteria to thrive, increasing intestinal permeability (“leaky gut”) and contributing to symptoms from feeling generally “off” through to diagnosed conditions.
Imbalances in the gut microbiome and the loss of keystone species have been associated with gastrointestinal disorders, metabolic diseases, neurological conditions and autoimmune illnesses.
THE F.PRAU HERO.
a hero keystone bacterium
for gut health.
Within the microbiome, F. prau stands alongside Lactobacillus and Bifidobacterium as a hero organism that helps to keep the gut environment stable and resilient.
F. prau has anti-inflammatory actions, supports immune homeostasis, influences mucus production and strengthens gut barrier integrity, helping to reduce intestinal permeability and “leaky gut.”
F. prau is also a major producer of butyrate, a short chain fatty acid that fuels colon cells and plays a central role in gut physiology and systemic health.
Butyrate is a key short chain fatty acid that fuels cells lining the large intestine, supports immune regulation and influences metabolic processes.
Low levels of F. prau have been linked TO:
- Gastrointestinal disorders (IBD, including ulcerative colitis and Crohn’s disease, IBS, CRC),
- Metabolic conditions (type 2 diabetes, non-alcoholic fatty liver disease),
- Nervous system diseases (Alzheimer’s, Parkinson’s, major depressive disorder, bipolar disorder, multiple sclerosis),
- Skin disease (atopic dermatitis)4 and respiratory tract infections (including Covid-195,6 and flu (H1N1)7).
“Butyrate, which is
produced by F. prau as it
feeds upon dietary fibre
like kiwifruit pectin,
plays a major role in gut
physiology and our health.”

Synbiotic strength:
25 mg Livaux® per billion CFU.
Livaux® is not only a prebiotic for the resident microbiome; it also acts as a highly efficient food source for added probiotics in synbiotic products.
As little as 25–50 mg of Livaux® per billion CFU is sufficient to support probiotic growth and activity, far lower than the gram-level doses often used with generic inulin or FOS.
This ultra efficient synbiotic dosing means products can:
- Combine probiotics with a small amount of a clinically characterised, whole fruit prebiotic.
- Keep capsule sizes or serving volumes small and palatable.
- Deliver both probiotic and prebiotic benefits from a clean-label, fruit-based ingredient.
Clinical Studies
on Livaux®.
HOW DO gold kiwifruit
bioactives WORK?
Livaux® concentrates the bioactive components of gold kiwifruit that are most relevant to microbiome balance, digestive comfort and immune function.
Key constituents include a blend of insoluble and soluble dietary fibre, complex pectin structures, polyphenols and antioxidant vitamins C and E.
What is dietary fibre
& what does it do?
Kiwifruit fibre and complex pectin
Livaux® concentrates the bioactive components of gold kiwifruit that are most relevant to microbiome balance, digestive comfort and immune function.
Key constituents include a blend of insoluble and soluble dietary fibre, complex pectin structures, polyphenols and antioxidant vitamins C and E.
Dietary fibre: kiwifruit fibre & complex pectin
The dietary fibre in Livaux® combines insoluble hemicellulose and cellulose with soluble pectin.
Insoluble fibre adds bulk and absorbs water, helping to speed transit and relieve constipation, while soluble fibre forms a gel-like matrix that becomes a fermentable substrate for colonic bacteria.
Kiwifruit pectin in Livaux® is one of the most structurally complex fibres found in nature, which means it is broken down slowly along the entire colon.
This slow, sustained fermentation profile makes Livaux® well tolerated and supports reductions in bloating and digestive discomfort, even in sensitive individuals.
F. prau has a particular affinity for the type of pectin found in Livaux®, so as this pectin is gradually fermented, F. prau can preferentially feed and expand without generating the excess gas often seen with rapidly fermentable prebiotics.
How Livaux increases
F. prau & supports
gut balance.
Livaux® is a patented, freeze-dried gold kiwifruit powder concentrate, derived from non-GMO New Zealand fruit, designed specifically to help native F. prau communities flourish.
Two human clinical studies have shown that capsules containing Livaux® significantly increase F. prau abundance, with participants also reporting better digestive comfort and quality of life.
- In functionally constipated adults, Livaux® approximately doubled the relative abundance of F. prau (from 3.4% to 7.0%), with eight out of nine participants experiencing a net increase.
- A more recent 600 mg per day study found that Livaux® raised F. prau numbers, improved laxation, reduced bloating and abdominal discomfort, and decreased gas-producing bacteria while increasing beneficial saccharolytic microbes.
These findings highlight how the whole fruit matrix of Livaux® can help restore microbial balance, support butyrate production and ease common digestive complaints.

What are polyphenols
and what do they do?
Polyphenols are micronutrients that are found in plants, with potent antioxidant and anti-inflammatory properties. When consumed by people, polyphenols protect from cell damage, assist in reducing chronic inflammation, and decrease risk of other disorders.
In a compositional comparison, Livaux® contained 41 unique bioactive phenolic compounds across 27 classes, whereas inulin contained only 9 phenolic compounds across 7 classes.
This represents about 355% more phenolic diversity in Livaux® than inulin, reflecting the complexity only a minimally processed, whole fruit ingredient can provide.
These 41 phenolics act as powerful antioxidants, helping to neutralise reactive oxygen species and support healthy lipid profiles, blood pressure, insulin sensitivity and systemic inflammatory tone.
Polyphenols also engage in a two-way interaction with the microbiota: they can modulate the composition of gut microbes via prebiotic and antimicrobial actions, while gut bacteria metabolise polyphenols into smaller, beneficial compounds.
In Livaux®, this polyphenol–microbiome interplay likely contributes to the favourable environment that allows anaerobic F. prau to thrive.
What are Vitamin C & E
& what do they do?
Livaux® naturally provides vitamins C and E, both of which are well-known antioxidant nutrients.
Together with polyphenols, these vitamins help to mop up reactive oxygen species, support immune function, and reduce inflammation from oxidative stress.
By dampening oxidative stress in the intestinal lumen, Livaux® may further enhance the survival and activity of oxygen-sensitive microbes like F. prau, reinforcing its precision prebiotic effect.

Frequently Asked
Questions with
Dr. Richard B Gearry.
Q: Why is there so much interest in F. prau from the scientific community?
A: As science has been able to delve into the microbiome that inhabits our gut with new advances, it has become clear that some microbes are present more often in healthy people than others, while some microbes are more commonly found associated with disease. Higher concentrations F. prau have consistently been found to be associated with health.
Q: What diseases are associated with low levels of F. prau?
A: Low levels of F. prau have been found in people with inflammatory bowel disease (Crohn’s disease and ulcerative colitis), asthma, obesity and even depression. However, it is not clear whether these associations are cause or effect.
Q: Can you take a probiotic supplement containing F. prau?
A: F. prau is an obligate anaerobe, therefore a probiotic preparation is unlikely to be effective as the preparation may not allow the bacterium to survive. Increasing the concentration of F. prau using a prebiotic just makes more scientific sense.
Q: How can you boost your natural levels of F. prau then, if you can’t supplement with a probiotic?
A: In theory, increasing F. prau could be achieved using a probiotic supplement including F. prau although it has proven technically difficult to achieve this. An alternative that is more likely to succeed is to provide the microbiome with foods that favour the growth of F. prau.
Q: What are the potential beneficial effects of boosting your F. prau levels in the gut?
Higher levels of F. prau are found in healthy individuals when compared to people with a range of illnesses. While this does not mean that F. prau protects people from these illnesses, it would seem that achieving higher levels of F. prau in the microbiome is not a bad aim.
