- Gut microbiome support - Livaux® gold kiwifruit powder is clinically shown to increase Faecalibacterium prausnitzii (F. prau) - a keystone beneficial bacterium - by over 100% within 28 days
- Prebiotic fibre - complex kiwifruit pectin feeds and supports the growth of beneficial gut bacteria, slowly fermenting along the entire colon for sustained, gentle support
- Digestive enzyme support - green kiwifruit extract provides actinidin (greater than 16,000 CDU/g), a proteolytic enzyme unique to kiwifruit that helps break down dietary proteins from meat, dairy, soy, and gluten-containing foods - and unlike bromelain or papain, it is highly active at stomach acid pH
- Butyrate production - 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 reduces inflammation
- Bloating and digestive comfort - clinical studies show Livaux® reduces bloating, abdominal discomfort, and gas-producing bacteria
- Bowel regularity - kiwifruit fibre and pectin support healthy transit and have been shown to improve laxation in clinical trials
- Beneficial bacteria growth - green kiwifruit skin fibre and polyphenols have been shown to increase levels of Lactobacillus acidophilus and Bifidobacterium bifidum in the gut
- Immune support - a healthy gut microbiome plays a central role in immune function; supporting beneficial bacteria helps maintain immune resilience
- Antioxidant support - 41 unique bioactive phenolic compounds in Livaux®, plus additional polyphenols from green kiwifruit, provide potent antioxidant activity to help neutralise free radicals
- Natural Vitamin C - kiwifruit is one of the richest natural sources of Vitamin C, supporting immune function and collagen production
- FODMAP friendly - the slow fermentation profile of kiwifruit pectin makes this formula well tolerated, including for those with IBS or FODMAP sensitivity
Kiwifruit Extract - Prebiotic + Enzyme Formula
Kiwifruit Extract - Prebiotic + Enzyme Formula
Kiwifruit is one of nature's most nutrient-dense fruits - and Kiwi Superfoods Kiwifruit Extract: Prebiotic + Enzyme Formula brings together two complementary NZ-grown kiwifruit ingredients to support your gut health from the inside out. Each capsule combines gold kiwifruit powder (Livaux®) with OxiFend green kiwifruit enzyme extract, delivering prebiotic fibre, digestive enzymes, polyphenols, and natural Vitamin C in a single, clean-label supplement.
Livaux® is the world's most awarded prebiotic ingredient - clinically proven to increase beneficial gut bacteria, support digestive comfort, and help restore a healthier gut microbiome. Paired with OxiFend green kiwifruit enzyme extract, naturally rich in actinidin - a powerful digestive enzyme unique to kiwifruit and highly active at stomach pH - this formula supports both the microbial and mechanical sides of healthy digestion.
Product of New Zealand. Gluten free. Suitable for vegetarians.
Key benefits
Why kiwifruit?
Kiwifruit is unique among fruits for the breadth of its digestive benefits. It contains a natural combination of prebiotic fibre, complex pectin, digestive enzymes, polyphenols, and vitamins C and E - all working together in a way that isolated prebiotic supplements simply cannot replicate.
New Zealand kiwifruit in particular benefits from the country's clean environment, mineral-rich soils, and high UV exposure - resulting in fruit with significantly higher levels of polyphenolic compounds than kiwifruit grown anywhere else in the world.
Gold kiwifruit (Livaux®) provides the most complex pectin structure of any commercially available fruit - a matrix that is slowly broken down along the full length of the colon, making it exceptionally well tolerated and effective at supporting beneficial gut bacteria, including the keystone species F. prausnitzii.
Green kiwifruit (OxiFend) contains actinidin, a proteolytic enzyme not found in most other fruits, which is highly active at stomach acid pH (1.5–3.5) - unlike common digestive enzyme supplements such as bromelain or papain, which work at much higher pH levels. This means actinidin gets to work exactly where protein digestion begins. Green kiwifruit is also rich in soluble fibre and polyphenols that further support beneficial gut bacteria growth.
Together, these two NZ-grown kiwifruit ingredients address both the microbial and mechanical aspects of healthy digestion - making this formula a genuinely comprehensive gut health supplement.

The science behind this formula
Livaux® gold kiwifruit powder - the world's most awarded prebiotic
Livaux® has won multiple NutraIngredients "Prebiotic of the Year" awards across the USA, Europe, and Asia. Produced in New Zealand from non-GMO gold kiwifruit using a gentle freeze-dry process, it 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, with participants also reporting improvements in digestive comfort and quality of life. A 600mg per day study found Livaux® raised F. prau numbers, improved laxation, reduced bloating and abdominal discomfort, and decreased gas-producing bacteria while increasing beneficial bacteria. Livaux® contains 41 unique bioactive phenolic compounds across 27 classes - over 355% more phenolic diversity than inulin.
OxiFend green kiwifruit enzyme extract - actinidin and digestive support
This freeze-dried NZ-grown green kiwifruit extract delivers high-potency actinidin enzyme activity - a cysteine protease (EC 3.4.22.14) that is highly active at stomach acid pH (1.5–3.5), unlike common digestive enzymes such as bromelain and papain which require a much higher pH to function. This makes actinidin uniquely effective at supporting protein digestion right where it begins - in the stomach.
Research has shown that actinidin from kiwifruit significantly increases the rate of digestion of dairy, meat, and soy proteins. OxiFend also contributes soluble fibre and polyphenols that support the growth of beneficial gut bacteria, including Lactobacillus acidophilus and Bifidobacterium bifidum.
What are the benefits of F. prausnitzii?
F. prau is one of the most important beneficial bacteria in the human gut. It has anti-inflammatory actions, supports immune function, and is a major producer of butyrate - a short-chain fatty acid that fuels the cells lining the colon and plays a central role in gut and systemic health. Low levels of F. prau have been associated with inflammatory bowel disease, IBS, obesity, type 2 diabetes, and certain neurological conditions. Supporting F. prau through targeted prebiotic nutrition is one of the most evidence-backed approaches to improving gut health.
