Kiwi Superfoods Kiwifruit Extract: Prebiotic + Enzyme Formula brings together two complementary NZ-grown kiwifruit ingredients in a single daily supplement - Livaux® gold kiwifruit powder and OxiFend green kiwifruit enzyme extract. Together they deliver prebiotic fibre, digestive enzymes, polyphenols, and natural vitamin C to support gut health from two distinct angles: the microbial and the mechanical.

Gluten free, suitable for vegetarians, and made in New Zealand.

Benefits

Gut microbiome support - Livaux® gold kiwifruit powder is clinically shown to increase Faecalibacterium prausnitzii (F. prau), a keystone beneficial gut bacterium, by over 100% within 28 days, supporting a healthier, more balanced microbiome
Digestive enzyme support - OxiFend green kiwifruit extract provides actinidin, a proteolytic enzyme unique to kiwifruit that is highly active at stomach pH, helping break down proteins from meat, dairy, soy, and gluten-containing foods - unlike bromelain or papain, which are largely inactive at stomach acid levels
Bloating, comfort, and regularity - clinical studies show Livaux® reduces bloating, abdominal discomfort, and gas-producing bacteria, while kiwifruit fibre and pectin support healthy bowel transit and laxation
Butyrate production and gut lining support - as F. prau feeds on kiwifruit pectin it produces butyrate, a short-chain fatty acid that fuels the gut lining, strengthens the intestinal barrier, and helps reduce inflammation
Immune and antioxidant support - a healthy gut microbiome plays a central role in immune resilience, while 41 unique bioactive phenolic compounds in Livaux® plus natural vitamin C from kiwifruit provide broad antioxidant protection
FODMAP friendly, gluten free, vegetarian-suitable, and made in New Zealand

More Information

Kiwi Superfoods Kiwifruit Extract: Prebiotic + Enzyme Formula is built around a genuinely unique combination of two NZ-grown kiwifruit ingredients that work together to support different but complementary aspects of digestive health.

Livaux® is the lead ingredient - a gold kiwifruit powder that has won multiple NutraIngredients Prebiotic of the Year awards across the USA, Europe, and Asia. Produced from non-GMO NZ gold kiwifruit using a gentle freeze-dry process, Livaux® delivers the fruit's full natural bioactive matrix: complex fibre, pectin, polyphenols, and vitamins C and E. Two human clinical studies have demonstrated that Livaux® significantly increases F. prausnitzii abundance - in one trial approximately doubling F. prau relative abundance within 28 days. Participants also reported improvements in digestive comfort, laxation, and quality of life. F. prausnitzii is one of the most important beneficial bacteria in the human gut - it has anti-inflammatory properties, supports immune function, and is a major producer of butyrate, the short-chain fatty acid that fuels the cells lining the colon. Low levels of F. prau have been associated with inflammatory bowel disease, IBS, obesity, type 2 diabetes, and certain neurological conditions.

OxiFend green kiwifruit enzyme extract provides actinidin - a cysteine protease enzyme unique to kiwifruit that is highly active at stomach acid pH (1.5–3.5). Unlike common digestive enzyme supplements such as bromelain and papain, which require a much higher pH to function, actinidin gets to work exactly where protein digestion begins. Research has shown that actinidin significantly increases the digestion rate of dairy, meat, and soy proteins. OxiFend also contributes soluble fibre and polyphenols that further support the growth of beneficial gut bacteria including Lactobacillus acidophilus and Bifidobacterium bifidum.

New Zealand kiwifruit benefits from the country's clean environment, mineral-rich soils, and high UV exposure - producing fruit with significantly higher levels of polyphenolic compounds than kiwifruit grown elsewhere in the world. Each bottle provides 30 servings at two capsules per day. Gluten free, vegetarian-suitable, and made in New Zealand

FAQ

What are Livaux® and OxiFend and why are both included?
Livaux® is a clinically studied gold kiwifruit powder that works as a prebiotic - feeding and increasing beneficial gut bacteria, particularly F. prausnitzii. OxiFend is a green kiwifruit enzyme extract that provides actinidin, a digestive enzyme unique to kiwifruit that helps break down dietary proteins. Together they address both the microbial side of gut health (bacteria balance) and the mechanical side (protein digestion), making this a more comprehensive formula than a standard prebiotic or enzyme supplement alone.

What is F. prausnitzii and why does it matter?
F. prausnitzii (F. prau) is considered one of the most important beneficial bacteria in the human gut. It produces butyrate - a short-chain fatty acid that fuels the cells lining the colon and plays a central role in gut and systemic health - and has anti-inflammatory and immune-supporting properties. Low levels of F. prau have been linked to a range of conditions including IBS, inflammatory bowel disease, obesity, and type 2 diabetes. Livaux® is one of the only ingredients clinically shown to specifically and significantly increase F. prau abundance.

What is actinidin and how is it different from other digestive enzymes?
Actinidin is a proteolytic enzyme found naturally in kiwifruit that helps break down dietary proteins. What makes it distinctive is that it is highly active at stomach acid pH (1.5–3.5) - the pH at which protein digestion begins. Common enzyme supplements like bromelain (from pineapple) and papain (from papaya) require a much higher pH to function, meaning they are largely inactive in the stomach. Actinidin works right where it is needed most.

What is butyrate and why is it important?
Butyrate is a short-chain fatty acid produced when beneficial gut bacteria - including F. prausnitzii - ferment prebiotic fibre. It is the primary fuel source for the cells lining the colon, helps strengthen the intestinal barrier, and plays an important role in reducing gut inflammation. Supporting butyrate production through prebiotic nutrition is one of the most evidence-backed approaches to improving gut health.

Is this product suitable for people with IBS or FODMAP sensitivity?
Yes. The slow fermentation profile of kiwifruit pectin makes Livaux® well tolerated, including for those with IBS or FODMAP sensitivity. The formula is classified as FODMAP friendly.

Does this product contain vitamin C?
Yes. Kiwifruit is one of the richest natural sources of vitamin C, and both the gold and green kiwifruit ingredients in this formula contribute natural vitamin C alongside their prebiotic and enzyme activity.

Is this product gluten free and vegetarian?
Yes. Kiwi Superfoods Kiwifruit Extract is gluten free and suitable for vegetarians. It is encapsulated in a vegetarian capsule and contains no animal-derived ingredients.

How long does one bottle last?
Each bottle contains 60 capsules at two capsules per day - providing 30 servings, a one-month supply.

Where is this product made?
Kiwifruit Extract: Prebiotic + Enzyme Formula is a product of New Zealand, made by Kiwi Superfoods in Albany, Auckland.
