Actazin® Kiwi Fruit: The science behind the benefits of Gut Feel

Meet Actazin® Kiwi Fruit, a scientifically proven functional food to help your Gut Feel its best every day.

Actazin® Kiwi Fruit is Unique 🥝

Kiwi is an amazing source of body loving nutrients including Vitamin C, fibre and antioxidants. It's also a welcome addition to breakfasts, smoothies and healthy recipes - with a naturally sweet flavour and green hue.

Actazin® is a powdered form of green kiwi fruit, exclusively harvested in New Zealand. It is a scientifically proven functional food with some pretty amazing benefits, especially for gut health.

Above and beyond regular kiwis which we know and love, clinical trials have proven Actazin® kiwi fruit to be effective at relieving digestive symptoms, improving gut function and acting as an effective prebiotic.


The Science Behind Actazin® Kiwi Fruit 🔬

We know that lots of foods are great for gut health, but what makes Actazin® special is to know exactly how this works.

Clinical trials and scientific research have been able to demonstrate a number of proven benefits of Actazin®, let's take a look!

1. Regular bowel movements

Actazin® can help to manage one of the most common and debilitating symptoms of poor gut health - constipation.

It is a natural source of fibre, enzymes, polyphenols, vitamins and minerals - all of which support normal bowel function.

Actazin® kiwi fruit fibres also have a unique hydration property, which supports water retention and adds bulk to stools making them much easier to pass.

This makes it a great gentle alternative to harsh laxatives, which can disrupt the gut and turn these symptoms from one extreme to the other!


2. Improves protein digestion

Studies have shown that Actazin® kiwi fruit contains an enzyme named actinidin, which helps to digest protein from food.

This helps to break down dietary protein into amino acids, which are used by the body for growth, repair and digestion. That's super important for everyone, but even better for people who are active and the elderly too.

Better protein digestion can also help to reduce bloating and feelings of being over-full.

3. Effective at a low dose of 600mg

Actazin® is the only green kiwi fruit powder with proven effectiveness at a low dose of 600mg.

The slow fermentation of the fruit means that you can enjoy gentle and comforting digestive health support - without the need to take a high dose supplement.

4. Acts as an effective prebiotic

Dietary fibre found in Actazin®, including kiwifruit pectin, provides a food source for good bacteria in the gut. The more food these gut bacteria get, the healthier the gut microbiome!

Studies have shown that kiwifruit pectin is slowly fermented by gut bacteria along the whole length of the colon - which reduces the excess gas and bloating which are common side effects of other prebiotics.

Actazin® feeds and supports good gut bacteria, increasing their growth and activity for better digestive health, regular bowels and improved immune function.


A daily serving of Actazin® can support a healthy and balanced gut microbiome, at the same time as helping to manage any digestive health issues you may have - in a natural, more gentle way.


Sounds good, does good! 💚

As well as being an amazing functional superfood, we also love Actazin® kiwi fruit for the following reasons.

🌱 100% Natural and certified Organic


🌱 Cold pressed - The whole kiwi fruit is gently processed into a skinless and seedless puree, which is dried and milled so that levels of key nutrients and bioactives are retained


🌱 Sustainably Sourced - Growers can not start picking the kiwi fruit until they get "clearance to pick", to help protect the land and biodiversity


🌱 Great Taste - Harnesses the naturally sweet flavour of New Zealand green kiwi fruit


🌱  FODMAP Friendly - Provides FODMAP friendly complex dietary fibre, which can help to reduce bloating and excessive gas
