As science continues to delve deeper, it only further validates what our formulators knew all along—that the key to well-being often lies in the natural world around us.
Get Ready for the Breakthrough That Will Redefine Your Digestive Health!
Are you feeling bloated, fatigued, or simply not at your best? These signs may not just be a fluke. They could be the warning signs of a gut in desperate need of a detox. Just as our homes, cars, and gadgets need regular maintenance to perform optimally, so does the intricate ecosystem of your gut. The toll of processed foods, environmental pollutants, and stress can disrupt the delicate balance in your digestive system, leading to a host of health issues. That's why a thorough cleanse is not a luxury—it's a necessity.
If your gut has been on the receiving end of a toxic beatdown, leaving you feeling sluggish, bloated, or out of whack, Internal Klenz Kit™ is the key to a new beginning.
First, help your body flush out toxins, backed-up waste, and unwelcome elements from your colon, then add a healthy dose of good bacteria (probiotics) to your gut, and feed the probiotics with powerful prebiotics (food for probiotics) ensuring they flourish and enhance your overall health.
Ordinary cleanses may not do the trick, and many generic probiotics are not powerful enough to get the job done. Our researchers developed Internal Sweep® - a powerful Dual-Action Colon Cleanse & Prebiotic formula… Gut Mate® - a super-strain probiotic formula that adds 20 DNA-verified probiotics to your gut... KlenzTea™ - a game changing detox tea that targets not just one, but every essential detox pathway in your body.
Finally, turn your gut into a probiotic paradise with ParaNix.
"It's like a detox spa for your gut microbiome, sweeping away any unwelcome elements and setting the stage for beneficial microorganisms to thrive again."
What Makes Internal Klenz Kit™ Exceptional?
Unlike those over-hyped colon cleanses that only scratch the surface, our cutting-edge formula delves deep into all 4 digestive zones
Revolutionize your digestive health by realizing that....
Most Colon Cleanses Target the Wrong End, Ignoring the True Source of Digestive troubles.
Click here to ...Read more
Prepare to be shocked as we unveil the harsh reality behind majority of colon cleanses and detoxes flooding the market. They place excessive emphasis on the colon while disregarding other essential players in your digestive system. Even those pricey options, costing a small fortune, often lack critical ingredients and rob you of the digestive comfort and confidence you deserve.
The Uncomfortable Truth:
By the Time Digestive Waste Reaches the Colon, Digestion is Virtually Done!
Allow us to divulge the inherent flaw in most colon cleanses. The real predicament with most colon cleanses lies in the fact that, by the time your digestive waste reaches the colon, digestion is virtually done! Sadly, many are unaware of this crucial truth, and the implications can be severe. A neglected digestive system can lead to a myriad of health issues, including gas, bloating, sluggishness, brain fog, and even skin problems.
Did you know that the real magic of digestion includes not just 1, or 2, but 4 digestive zones...Read more
Most people consume their food without giving a second thought to what happens next. But here’s the inside scoop: There’s a backstage crew working 24/7 to turn that steak dinner or vegetable stir-fry into energy and nutrition for your body.
Zone 1: Stomach - The Ultimate Food Processor and a Master Chemist ...Read more
In zone 1, your stomach kickstarts the entire digestive process. Your stomach isn’t just a bag that holds food; it is a muscle-packed powerhouse vigorously churning and grinding each morsel you eat into a velvety-smooth pulp. It also releases a powerful mix of gastric acid and digestive enzymes, further breaking down the food to optimize it for next stages of digestion. This resulting semi-fluid mixture is known as 'chyme'."
A well-functioning stomach prepares food for optimal nutrient extraction downstream. The better your stomach performs, the smoother the next stages will be. Ignoring this zone can mean leaving precious nutrients on the table and missing out on peak performance.
Ginger, dandelion root, papaya, apple cider vinegar, pineapple, lemon, bitter fruits are believed to stimulate the secretion of these juices or support digestion in general. Highlighted herbs are among the 70 ingredients that make up the Internal Klenz formula.
Unlocking Nature’s Secret: How Stomach Acid Powers Up Your Protein Digestion...Read more
Pepsinogen is an inactive enzyme, produced by the stomach, becomes active when exposed to hydrochloric acid (HCL), transforming it into pepsin, which breaks down proteins. Lack of adequate pepsinogen and HCL in the stomach can lead to impaired protein digestion and other digestive complications.
Neglecting Zone 1 Can Be the Beginning of Your Digestive Downfall, as Poor Stomach Health Sets the Stage for Inefficient Digestion
Zone 2: The Hard Work of Digesting Proteins and Fats...Read more
In zone 2, your liver, gallbladder, and pancreas kick into action. When chyme enters your intestines, your liver and pancreas kick into action by delivering BILE and enzymes to break down and metabolize food. Without bile and enzymes, you may experience poor digestion.
Milk thistle, dandelion, turmeric, artichoke, burdock root, peppermint, Oregon grape root, beetroot, bitter Melon, and goldenseal are believed to support liver and pancreas. Highlighted herbs are among the 70 ingredients that make up the Internal Klenz formula.
Liver: It’s Not Just to Hold Down Liquor, Like a Pirate on Payday: It’s The Star Quarterback of Your Digestive System ... Read more
When it comes to digesting food and delivering energy to our bodies, not all nutrients are created equal. Take simple carbs and sugars, for instance. These uncomplicated molecules zoom straight into our bloodstream. They‘re the fast track to energy, no frills, no fuss. Your body barely lifts a finger to digest simple carbs and sugars.
On the other hand, proteins and fats are more complex molecules that require our bodies to roll up their sleeves and get to work. They require extra steps, more time, and more energy. When you consume these nutrients, your liver and pancreas step in, doing the heavy lifting.
The Right Tools Make All the Difference
Liver produces bile, a golden-green fluid that emulsifies fats, breaking them down into smaller droplets, making it easier for the body to digest them. Think of bile as the scissors, slicing up the bulky packages so they‘re easier to handle. When you‘re indulging in a fatty meal, your liver sends bile straight to your small intestine. But, between meals, it diverts bile to the gallbladder, nature‘s reserve tank, for your next meal.
Pancreas: The Unsung Hero of Protein Digestion
Then there‘s the pancreas, quietly churning out digestive enzymes, the magic workers. They diligently pick apart proteins, turning them into the building blocks of life - amino acids. Only then can these molecules enter the bloodstream and be whisked away to the cells that need them.
So here‘s the deal: think of these 3 as the ultimate digestive dream team. The liver‘s crafting the all-important bile. The gallbladder‘s waiting in the wings, ready to release it on cue. And the pancreas? It‘s there, making sure no food goes unprocessed. Together, they‘re ensuring every delicious morsel you eat gets the VIP treatment, transforming them into nutrients your body craves.
What If Your Liver and Pancreas Took a Day Off?
The Shocking Truth Behind Empty Calories vs. Powerhouse Nutrients!
Proteins and fats would struggle to break down into smaller, more digestible forms. It‘s like trying to stuff a whole pizza in your mouth all at once. Your body can‘t properly digest and absorb them. Leaving proteins and fats to wander through your intestines and potentially lead to all sorts of unpleasantness like bloating, occasional diarrhea, and nutrient deficiencies. In a nutshell, it‘s a mess you don‘t want to deal with!
On the other hand, carbs and sugars are effortlessly digested; your body hardly breaks a sweat to process them.
The Result? You Are Left With Empty Calories, Instead of Essential Nutrients!
Zone 3: The Small Intestine - Where Digestion’s Hard Work Finally Pays Off
In zone 3, millions of finger-like projections in the small intestine, called villi, efficiently absorb nutrients into your bloodstream. Sluggish digestion can take up to 60 long, uncomfortable hours. By the time digestive waste reaches your colon, it's often too late. How long this waste sits in your colon can be a sign of how well Zones 1-3 have done their job. When digestion is incomplete, the waste can stagnate, making it harder for your muscles to push it out. No one wants to accumulate waste and toxins in their body any longer than necessary!
Processed Foods: The Silent Destroyer of Your Digestive Health, One Bite at a Time... Read more
Our modern diet with highly-processed foods with high sugar, high carb, and low fiber contain very few or no digestive enzymes which can make it harder for your body to digest your food. The longer the waste sits in the body, the more toxins it releases. Slow-moving waste may produce gas that can make you feel occasionally bloated and very uncomfortable. These gases may smell so bad that they are genuinely unbearable. Rotten eggs, strong metallic odors, sewer gas—they’re all disgusting.
Then, your body is sounding the alarm, begging for assistance! It’s time to listen and answer its call with utmost urgency. Reboot, revitalize, and reinforce all 4 digestive zones.
That sign is your body is sending out an urgent plea for help. It's a crucial moment to heed the call and act swiftly. Give your digestive system the restart it deserves. It's time to rejuvenate and strengthen your body's four essential digestive areas.

Our products have been formulated with a comprehensive blend of 15 prebiotic fibers, including citrus pectin, inulin, and FOS. This diversification ensures that a wide range of beneficial bacteria in your gut get the nourishment they need.

How Long Should You Cleanse? Understanding the Optimal Duration for Maximum Benefits
Many cleanses last only a few days to a few weeks, which is often insufficient for achieving meaningful digestive health benefits, potentially leading to wasted time and money for many.
Addressing years of dietary missteps, accumulated toxins, and a skewed microbiome can take time.That's why naturopathic doctors recommend a minimum of 30 days—and ideally 60 to 90 days—to experience a thorough internal cleansing.
Bottom line: Don’t Be Fooled by “Quick” Cleanses!
“What amazed me about this cleanse program is that it covers everything and does it thoroughly and correctly for 60 days and not some 3 to 14 day product in a bottle. ” ¤ - Posted by Tom B

Great experience overall
Tried this for a few weeks and had a great experience. Unfortunately when the products arrived, the specific tea bags were expiring less than 1 month later. I used them anyways and was fine but would hope for better in the future if I were to ever use this again.

Internal Cleanse Program
Currently in the middle of a 60 day fast. It cleared up my problem with sneezing and runny sinuses every time I went outside. Being from the country I never had these issues growing up.

It is so easy to take and really works! I am a real person, and I am so excited to have healthy intestinal waste for the first time ever! My colon is so healthy that there's no odor when I use the bathroom, and it's enjoyable now, instead of uncomfortable! Also, the parasites come out effortlessly!
