Review of Xtend-Life Kiwi-Klenz

Xtend-Life Kwi-Klenz is a popular supplement but is it the best probiotic supplement on the market today? Is it even a probiotics supplement? This review will cover all aspects of the product including raw ingredients, quality control standards, guarantee and more.

Xtend-Life Kiwi-Klenz is a digestive supplement that helps to improve the digestive processes but is it the best probiotic supplement? It is an all-natural digestive aid supplement that is made in pharmaceutical-quality facilities, which facilities are in fact, cGMP (current Good Manufacturing Practices) compliant facilities.

As of July 13th, 2024, it is considered to be one of the best digestive products on the market. (Or is it? That’s what Xtend-Life says anyway.)

The digestive supplement, according to Xtend-Life its New Zealand-based manufacturer, may help to correct digestive problems and serve as a mild intestinal cleansing agent.

This is a new product for its manufacturer. It was introduced to the global market June 2011. Xtend-Life’s marketing material says that it is a one-of-a-kind supplement that has applicability to any age.

That is debatable but good digestion is not common. In fact, most have problems with good digestion and don’t even know it.

Seeking to Develop the Best Probiotic Supplement?

Xtend-Life says they conduct their own in-house clinical research and testing. Regarding customer interest specifically, they created their own survey research project using Likert-scale questions. According to the company’s internal research, those test subjects who used it the longest expressed the greatest satisfaction with Kiwi-Klenz. Those who didn’t have long familiarity or usage of the product seemed positive but not as enthusiastic as the long-term users.

With all of its product line, and certainly with this product, Xtend-Life conducted significant research before it was introduced to the market. However, they also conducted post-intro research as well.

Raw Product Material Sourcing So As to Create the Best Probiotic Supplement on the Market

As with their entire product line, Xtend-Life says that this product is crafted with quality raw elements that receive  pharmaceutical-grade certification with all raw product material tested at separate, third-party, cGMP-compliant laboratories  like Alkemists Laboratories in southern California, USA.

Moreover, as with all their products, Xtend-Life also produces what’s called a Certificate of Analysis (COA) is created and internally filed for record keeping purposes with each batch of raw ingredients. This testing and confirmation confirms not just the nutritional potency but also the purity of each batch’s raw ingredients.

Again, as with all of their products, the Kiwi-Klenz product is created in Xtend-Life’s  cGMP-compliant facilities, which is the highest standard possible for quality and product purity. This is the same standards pharmaceutical drug companies adhere to as required by law. This is uncommon as most supplement companies outsource the product creation. Xtend-Life owns their own manufacturing facilities that meet FDA requirements and they’ve done this so as to ensure product quality.

Xtend-Life is justifiably proud of this. However, this certification and commitment to quality is one of the reason why Xtend-Life’s products are more expensive as they are made with such exacting quality

Is Xtend-Life Kiwi-Klenz the Best Probiotic Supplement?

It’s doubtful. Believe it or not, your mouth is the first step in the digestion process. There, foods are broken down and masticated with saliva. Your stomach is the second step in the digestive process. Next, nutrients are released in the duodenum (the upper intestine) with the stomach coupled with the intestinal tract is the sewage system of your body. Norman W. Walker, D.Sc., Ph.D. (1979) in his book, Colon Health: The Key to Vibrant Health, says, “…the colon is the body’s sewage system” (p. 9).

This product is what’s called a “pre-biotic” agent. What it does is essentially inhibit bad intestinal bacterial growth. The benefit to you and me is that that everything you eat is broken down, digested  better assimilated. Another natural consequence is that you have more energy for less food eaten. And, of course, a more efficient digestive system. That is why it can be called a probiotic supplement although that is an attendant benefit.

According to the company, there are other health benefits that Kiwi-Klenz provides. According to my research, the manufacturer says the product, “includes the kiwifruit enzymes, phenolics and soluble fiber, which are all critical components for good intestinal health.”

Let’s get more specific. The company says that this product is designed to work with the four disparate but related elements relating to digestion and assimilation health. This digestive product, they say, improves the digestion of proteins through the action of enzymes. Again, the natural end result is improved assimilation.

The natural byproduct or causal effect is that one will then get less stomach upset as more of the food stuffs eaten will be broken down properly. Also, it should be mentioned that Kiwi-Klenz also has some soluble fiber, which is vital to health intestinal and colon function. That said, it is not a colon cleansing supplement like the Blessed Herbs or Colonix product. I can tell you from experience that it is not as robust as psyllium seed or husks. It can certainly help, though.

While it’s not an anti-virus or anti-viral supplement, it will, Xtend-Life asserts, inhibit the growth of bad bacteria or pathogens, which result in disease.

The end result of this product is that it assists, restores, and facilitates optimal assimilation. Essentially, your entire digestive system, from the “processing plant” of the stomach to the assimilation work of the intestines and the discharge and assimilation of the large colon, will all perform better; your overall health will be improved as well as the digestive and intestinal systems will efficiently work the way they were supposed to.

Xtend-Life says that when you add their other supplements to Kiwi-Klenz, they will perform better and enhance assimilation of those products as well. In that way it is among, perhaps, the best probiotic supplement products on the market today.

The Xtend-Life Kiwi-Klenz Ingredients

This is a simply designed supplement without a lot of ingredients. The ingredients of Kiwi-Klenz are kiwi-fruit extract and kiwi-fruit powder. For those who want to avoid collagen-based gelatin capsules, they will also be happy to hear that It’s encapsulated in vegetarian capsules with two minor fillers.

As mentioned earlier in this article, these ingredients are certified pharmaceutical-grade pure by independent, third-party laboratories such as Alkemists Laboratories in Costa Mesa, California, USA, and by Cawthorn Institute and AsureQuality in New Zealand.

How Much Does Xtend-Life Kiwi-Klenz Cost?

One bottle of Kiwi-Klenz has 60 capsules and sells for $35.50 USD (United States Dollar). This is a month’s supply. For orders totaling $60 USD, you get free shipping anywhere in the world. For orders that don’t hit the $60 threshold, Xtend-Life charges a flat $6.50 fee for worldwide shipping. Either way, it’s a good deal with the shipping.

Is There a Product Guarantee?

365 day guarantee graphic

Xtend-Life offers an astonishing full one-year, product-satisfaction guarantee on all their products, the Kiwi-Klenz product included. If you’re not happy with it, you can get either a monetary refund or a product replacement. One-year guarantees are rare but especially rare for supplement companies. Their guarantee used to be six months but they increased it to a full year about two years ago as of this writing.

However…the company has been known to engage in dishonest business practices and it is by no means a certainty that they would adhere to the fulfillment of this guarantee. It is great marketing hype but dubious in actual practice given the company’s dishonest predilections.

Consumer Reviews

Kiwi-Klenz is still a new offering, but it has still received some superb customer feedback. Here are a few testimonials taken from Xtend-Life’s website.

Thought I would give some feedback on Kwi-Klenz. I have been using it for over a month now and must admit it is probably the only supplement I have taken where the effects of taking it are so noticeable. After a week my digestion had improved 100 fold, but the most amazing effect was my sugar cravings disappeared and appetite reduced markedly. I find when I eat, I get full quicker. I recommended it to a workmate who reported the same effect to me. Possibly the best weight loss supplement out there! I never send reviews in, but had to for this, as everything it says it will do, it has. And it is affordable. Thanks for a great supplement!

I started taking one capsule of Digesten-K (now called Kwi-Klenz) and found things were not moving as I had hoped, but after increasing to two capsules thing really started moving ! After a nasty Sunday, running to the toilet all day things settled down and I felt great. After having a very stressful year I had let myself get very run down, not eating or exercising as I should. My system was so clogged up with rubbish I needed help. I feel this product did help me. I am exercising again and do not eat as much as before I started taking Digesten-K, I also find I am eating healthy food. I have cut down to one capsule a day, but seriously considering going back to two. I think my skin is better and I am not heading to the toilet more than twice a day.

I’m very impressed by all your products. When I tried Kiwi-Klenz, the most accurate thing I could say about it was that it removed uncomfortable stomach pains for me. Not that I have severe problems. I felt “cleaner” or just stronger after eating. I didn’t feel as naturally tired. It definitely seems to help with my digestion and I think you for that.

Any Customer Complaints?

A good review must also must discuss the negative. In a survey conducted internally, which I’ve previously referenced, 7.8% either found the product dis-satisfactory or very dis-satisfactory.

The remaining 92.2% is dispersed as follows: 33.5% found it neutral, 35% were satisfied and 23.7% were very satisfied.

Satisfaction with Kiwi-Klenz was 3.7 out of 5 the longer it was used. These survey findings were compiled both prior to its launch in June 2011 and up until early November 2011.

It seems to be a good product overall and could still be “getting its legs.”

Based on the statistics provided to me by Xtend-Life itself, it is actually one of their better selling products. It is currently their fifth most popular supplement product sold as of this writing (late September, 2013).

One thing I’ve noticed is that it does help produce a good bowel movement the next morning. It’s certainly easier to take than some of the other similar products on the market. However, that said, it is not a colon cleansing agent per se. What it is is a supplement that will help people make better use of the food they eat from a digestive standpoint. It really is more of a probiotic supplement than anything else, but clearly it has multiple capabilities.

Furthermore, the product should not be thought of as a competitor to Blessed Herbs herbal colon cleanse product or the Colonix product either. Both of those are “heavy duty” colon cleansing agents that are designed for that purpose alone.

So, yes, Kwi-Klenz should be thought of as a digestive or pro-biotic aid. In that realm, it seems to perform quite well.

Where Can I Get More Information?

You can get more product information at their website by clicking on the bottle graphic below. There, you’ll find clinical studies and other information that seems to be quite comprehensive.

Where Can I Buy It?

Xtend-Life Kiwi-KlenzYou can buy Kwi-Klenz here as of July 13th, 2024.

Whether it’s the best probiotic supplement or not is up to you to decide but this does appear to be a quality digestion supplement. “Appear” is the key word as Xtend-Life is dishonest in its business operations — something I’ve personally experienced at quite a cost to myself.

Nevertheless, I hope this review of the Xtend-Life Kiwi-Klenz product has been helpful to you.
