Features & Benefits

Kiwi-Klenz - A World First for Complete Digestive Support

Say goodbye to bloating, and hello to a healthy, happy gut. Kiwi-Klenz combines premium green and gold kiwifruit extracts for complete digestive support. With two capsules a day, Kiwi-Klenz increases your bowel regularity and repairs damage in your gut. It even supports a strong immune system.

Healthy Microbiome

Restore your microbiome for a healthy, happy digestive system and wider health benefits such as improved immunity.

Livaux is clinically proven to increase levels of the healthy gut bacteria F.prau. Low levels of F.prau are associated with an array of digestive complaints and health conditions.

Faster Digestion

Say goodbye to that awful feeling of bloating and gas after a meal.

Digesten Kiwifruit Complex significantly increases the rate of digestion of dairy, meat and soy proteins. This effect is due to the enzyme Actinidin that breaks down proteins.

Repair Damage

If stomach cramps, bloating, gas and frequent exhuastion sound familiar, you may have a 'leaky gut'.

When the lining of the digestive system is damaged, for example through poor diet, partially digested food, toxins and bugs can enter our bodies, triggering health problems. L-Glutamine is considered the most important nutrient for healing the gut lining.

Bowel Regularity

Increase your bowel regularity with the unique combination of green and gold kiwifruit.

With constipation, waste and toxins stay in your body for longer and you are forced to strain in order to have a bowel movement. The ingredients in Kiwi-Klenz are clinically proven to have a gentle effect in achieving normal bowel movement.

Kiwi Klenz

Kiwi-Klenz - Your Immunity Sidekick

An estimated 70% of your immune system is located in your gut, which is why looking after gut microflora is so important for good health and your body’s defences against illness.

Kiwi-Klenz works directly and indirectly to support the immune system

  • Contains Livaux®, an extract from gold kiwifruit, which has been clinically shown to reduce cold and flu symptoms in children and older adults.
  • Livaux® also spurs the growth of beneficial bacteria called F.Prau which produces butyrate to help prevent bugs from getting from your digestive system into the rest of your body.
  • Provides specific polyphenols and fibre which help keep pathogenic bacteria in check.
  • Kiwi-Klenz contains added vitamin C and D to give the immune system that extra boost.

Supercharged Kiwifruit in a Capsule

Golden Kiwifruit

Gold Kiwifruit

Livaux® is a multi-award-winning ingredient, most recently being awarded prebiotic of the year at the Nutra Ingredients Asia Awards. It is made from the flesh of 100% New Zealand grown, premium gold kiwifruit.

It’s been shown in clinical studies to support a healthy microbiome by specifically increasing healthy gut bacteria called F.prau. Low levels of F.prau. are associated with serious gut diseases and other health conditions. By restoring healthy levels of F.prau, Livaux® supports a healthy gut and promotes wider health benefits.

Livaux® increases the amount of the short chain fatty acid in the gut called butyrate in the gut. Butyrate serves to maintain the gut barrier and has anti-inflammatory and immune enhancing properties for a healthier gut and healthier you.

Green Kiwifruit

Green Kiwifruit

Digesten® Kiwifruit Complex is made from the skin, flesh and seeds of premium, New Zealand grown green kiwifruit.

It increases the abundance of good bacteria in the gut, including L. acidophilus and L. bifidum. These good bacteria are part of a healthy microbiome that has wide ranging health benefits, including promoting gut health and producing lactic acid which helps fight off harmful bacteria.

Digesten® also aids the digestion of proteins such as milk, beef and tofu so you can say goodbye to that awful feeling of bloat after a meal. It is clinically proven to reduce constipation, keeping waste and toxins from building up in your system.

L glutamine


L-Glutamine is an amino acid, with important roles in the immune system and digestive health. It helps protect against the problems associated with leaky gut (such as inflammation and digestive problems).

Due to its major role in the intestinal system, L-glutamine supports overall immune health by supporting intestinal cells.

Studies have shown that L-glutamine supplements may help improve immune function during infections.

Kiwi-Klenz packs the digestive benefits of six kiwifruit into just two capsules. The kiwifruit in Kiwi-Klenz are 100% New Zealand grown. This means exceptional purity (organic and no GMO), plus higher bioactivity levels than kiwifruit grown elsewhere, due to New Zealand’s higher UV levels.

Prebiotic, Probiotic, Postbiotic – What’s Best for Me?


The fibre in Kiwi-Klenz is a prebiotic. It provides the fuel for good bacteria to grow in your gut. When healthy bacteria thrive, it limits the growth of bad bugs and aids digestion so you get the best from the food you eat.

The Fuel

The Fuel


Probiotics are the good bacteria that live inside your gut. You can also take probiotics in supplement form. Probiotics provide benefits by converting prebiotic fibre, such as the fibre in Kiwi-Klenz, into compounds that have benefits for your health.

Good Bugs



Postbiotics are the bioactive compounds that good bacteria produce when they consume prebiotic fibre, such as that found in Kiwi-Klenz. Postbiotics have lots of health benefits ranging from healthy digestion to healthy immunity.

The Goods



While they sound similar, prebiotics and probiotics play different roles in keeping a healthy digestive system.

So Which is Best?

Both prebiotics and probiotics have important roles to play in our gut health. Prebiotics set up the right environment for healthy bacteria in our digestive systems and allows your body the freedom to create the levels of healthy bacteria in the proportions it needs. In the case of probiotics, you don’t usually know either the types of bacteria you need, or the levels. so it is more of a guess.

That’s why Xtend-Life focus on prebiotics that helps the microbiome feed the good bacteria and suppress the pathogens.

Why did we reformulate Kiwi-Klenz?

With the continual advancement in research and science; we reformulate our products where we believe that it would be beneficial to our customers.

The addition of gold kiwifruit helps to increase the short-chain fatty acids which is found in the gut. This is called Butyrate, which helps prevent bugs from moving out of your digestive system into the rest of your body. 

The other added ingredient is the amino acid L-Glutamine, which plays an important role in supporting your immune system and digestive health.

My bowel/digestive system feels upset when I have taken it?

If you find that taking 2 capsules per day is upsetting your digestive system, reduce the dose to one per day.

Why did the serving size go from 1-2 per day to 2 capsules per day?

For optimum benefit we recommend two capsules per day but if you find one capsule per day is suffice; continue to do so.

Will it upset my stomach if I am already taking the old formula of Kiwi-Klenz?

This is very unlikely, however if you find a change in your digestive/bowel system we recommend reducing your dose to 1 capsule and only taking it every second day for 7-10 days, then increase your dose to 1 every day.

Once your system settles increase the dose to two when your system has adjusted to the new formula.

Can I eliminate my daily probiotic when I start taking Kiwi-Klenz? 

Yes, you can. Probiotics are useful at times – after a course of antibiotics, for example – but are best used on a short-term basis. There is not enough conclusive research about the regular and long-term use of probiotics.  

Kiwi-Klenz is not a probiotic, but rather it is a prebiotic that supports your digestive system to naturally produce its own good bacteria. It also contains phenolics which help to eliminate bad bacteria within your intestinal tract. 

Can I give Kiwi-Klenz to my child? 

Yes, Kiwi-Klenz may be used by children. We recommend following dosage:  

1-5 years old: Begin with a ½ capsule every second day for the first two weeks, then increase to ½ capsule daily if necessary.  

6-12 years old: Begin with one capsule every second day for the first two weeks, then increase to one per day if necessary. 

It’s important to monitor the results and only increase the dose if your child is tolerating the product well. It’s also important to ensure your child has plenty of fluids when taking Kiwi-Klenz. If easier, you can open the capsule and add the contents to unheated food, such as a smoothie, juice or cereal. 

Can Kiwi-Klenz help with IBS? 

Kiwi-Klenz can help those affected by Irritable Bowel Syndrome (IBS). Kiwi-Klenz features soluble fiber, digestive enzymes and prebiotics to help feed the growth of good bacteria and limit the growth of bad bacteria. Regulating the digestive processes may be very useful in lessening the symptoms common to IBS such as bloating, indigestion, wind or constipation. 

Is Kiwi-Klenz useful for 'leaky gut syndrome'? 

Kiwi-Klenz certainly may be of benefit for leaky gut syndrome. Supporting healthy digestion means that the gastrointestinal system is able to focus on daily issues involving the integrity of the intestinal mucosal, to ensure healing and cell regeneration can occur. 

The enzymes in Kiwi-Klenz help to breakdown protein, which is why this product is designed to be taken after a main meal. By improving digestion, it may help to prevent large toxins and microbes from breaching the digestive tract so that they can be safely excreted from the body as intended. 

Can I take Kiwi-Klenz if I’m allergic to kiwifruit? 

No. We suggest that anyone with kiwifruit allergies should avoid Kiwi-Klenz, as this product is extracted from the flesh, seeds and skin of the fresh fruit. There may be other alternative options in our range to help support your digestion such as Total Balance and the Omega 3/DHA Fish Oil.

Can Kiwi-Klenz be used as part of a detox plan? 

Kiwi-Klenz is not designed as a detoxification supplement. The body requires specific vitamins, minerals, amino acids and herbs to support detoxification. However, due to its high soluble fiber content, Kiwi-Klenz may be very helpful in removing built-up toxins or waste in the digestive system. 

Can I use Kiwi-Klenz to help cure my chronic digestive concerns? 

Kiwi-Klenz cannot be considered a 'cure' for chronic digestive conditions – but it may certainly be helpful. In order to treat a particularly troublesome or stubborn digestive concern the daily dose may be increased to 3 capsules per day, taking 1 capsule after each meal, with plenty of water. 

Is there any sugar in Kiwi-Klenz, since it’s made from fruit? 

Yes, there is naturally occurring fructose within Kiwifruit, so of course, this will be within the supplement. There is no added sugar. Fun fact: Kiwi fruit is one of the lower fructose-containing fruit.

    I'm not fond of the smell or taste but other than that it's okay. I haven't decided yet if it's helping with my intestinal issues or not. I've only taken it for 1 month and I always hear you need at least 3 months of taking any medication or supplement to know if it will work for you or not.
