If you’ve struggled with stress, anxiety, or other emotional issues, it’s likely no surprise to hear that mental health is intrinsically tied to our digestive health.

What is zuPOO?

zuPOO is an all-natural supplement for gut health. This colon cleanser flushes your gut of waste and toxins, eliminating up to 20 pounds of fecal buildup and reducing stomach bloat. It can also:

  • Benefit short-term weight loss
  • Help restore natural microbiome
  • Enhance mental and physical health

Christopher Walker founded UMZU – the company that manufactures zuPOO – in 2015 after achieving personal success in treating the effects of a pituitary tumor he developed while a neuroscience student at Duke University. Walker’s published findings led others to push him into developing all-natural hormone-balancing treatments.

Since its founding, UMZU has expanded across the health and wellness market. Today, it offers an array of all-natural, scientifically backed supplements for:

  • Gut health
  • Energy
  • Weight-loss support
  • Bone health
  • Improved mood and focus

Does zuPOO work?

The science backs up zuPOO’s ingredients, and we found the product to be effective without the bloating, gas, and discomfort we’ve experienced with other colon cleansers.

zuPOO contains powerful, all-natural laxatives that help purge the body of accumulated waste and toxins. In fact, it’s effective enough that we recommend those taking it have constant bathroom access during the cleansing period. zuPOO is most effective when combined with a healthy lifestyle, including diet, exercise, and proper hydration.

Keep in mind: zuPOO is intended for short-term use. Taking this supplement beyond the recommended 15-day regimen is inadvisable due to potential side effects, including liver toxicity.

How zuPOO works

When you prepare to use an all-natural colon cleanser like zuPOO, you should know what to expect and plan your circumstances upon those expectations. You’ll want ready access to a restroom because you’ll need it for the next two weeks. For instance, those with highly focused, face-to-face jobs like teaching might want to plan their colon cleanse during summer break.

zuPOO contains several botanicals and all-natural compounds that work together to purge your digestive tract of unwanted waste and toxins. These scientifically backed ingredients include:

Cascara sagrada

Cascara sagrada is a derivative from the dried bark of a species of buckthorn tree native to western North America. It contains natural compounds called anthraquinones. They have several therapeutic uses, including the treatment of constipation, cancer, multiple sclerosis, and arthritis. Cascara sagrada is a natural laxative used historically by Native American people that you can find today on many pharmacy shelves for digestive health. However, you should note that long-term use of cascara sagrada is not advised in high doses, as this can lead to liver toxicity. Medical researchers do not recommend its usage if you are pregnant or nursing.

Senna leaf

Senna leaf is another common herbal laxative found in over-the-counter supplements. While researchers consider senna safe in recommended dosages for limited periods, it can lead to liver injury in excess. However, liver injury cases are rare and reverse themselves upon discontinued use.

Fennel seed powder

Fennel seed has a long history as a traditional medicinal treatment for reproductive, endocrine, respiratory, and digestive ailments. This herbal plant shows promise in scientific studies for its antiviral, anti-inflammatory, and anti-tumor properties, among other benefits.

Burdock root powder

Burdock is an antioxidant and anti-inflammatory botanical with a history of treating hepatitis, gout, and hypertension. Burdock extracts contain the natural dietary fiber inulin, which helps promote healthy digestion.

Bentonite clay

Researchers and scientists have published thousands of studies on bentonite clay’s benefits and potential treatments. This natural clay can benefit the body’s detoxification, relieve skin irritation, and help in treating diarrhea, constipation, colitis, and irritable bowel syndrome (IBS).

Buckthorn bark powder

Buckthorn is a rich source of anthraquinones and a similar laxative to cascara sagrada. It may help treat various health conditions, including cancer, constipation, skin disorders, and hemorrhoids.

Aloe leaf extract

Clinical trials demonstrate the safety and efficacy of aloe vera leaf for the short-term treatment of irritable bowel syndrome (IBS). This common house plant has centuries-long use in traditional Indian medicine for treating infections and digestive issues like constipation. Today, scientists and researchers continue studying aloe vera’s therapeutic uses for diabetes, metastatic cancer, ulcers, and surgical wounds.

Slippery elm extract

Slippery elm, a prebiotic with use dating back centuries as a therapeutic in Ayurvedic medicine, boasts several health benefits, from improving gastrointestinal health to reducing inflammation.

Milk thistle

Milk thistle is a common ingredient in wellness supplements supporting digestive and liver health. Some studies have shown milk thistle to be helpful in the treatment of diabetes, but more research is needed in determining its efficacy in this use.

Cayenne pepper extract

Capsaicin, the primary component of cayenne pepper, shows the potential to promote metabolic and vascular health and prevent and heal gastric ulcers.

How to take zuPOO

When you begin your zuPOO regimen, you’ll take two capsules daily over 15 days. UMZU recommends taking zuPOO at bedtime with a full glass of water. Over the next two weeks, you’ll want to maintain a high water intake daily to prevent dehydration through excessive excrement.

Within the first 48 hours of taking zuPOO, you may experience bloat and discomfort as your body prepares to expel waste. And this is where having a nearby restroom at all times is essential. Some consumers expel waste over eight times daily during the cleanse period.

Once your regimen is complete, you should feel lighter and relieved of bloat, gut discomfort, and constipation. While UMZU recommends performing a zuPOO cleanse every 90 days, we feel this is somewhat excessive and potentially unsafe. We suggest consulting with your doctor or dietician if you continue using zuPOO beyond the occasional colon cleanse.

Is zuPOO safe?

zuPOO is safe when used as directed for the 15-day regimen. Some of the most important factors to consider with zuPOO are the impacts of its ingredients and how they might interact with any current or long-term medications you may take. For instance, several of zuPOO’s main ingredients, including cascara sagrada, can cause liver problems with extended use. Those taking medications or with chronic medical conditions should consult their doctor before use.

UMZU does not recommend this product for those who are pregnant or nursing, and it is unsuitable for children. If you have a history of eating disorders or dietary supplement abuse, avoid zuPOO.

This product is intended to assist with healthy digestion, not long-term weight management. While weight loss may be a short-term benefit, laxatives should not be used for long-term weight loss or as a “quick fix” solution. Doing so is harmful to your body.


Like all supplements from UMZU, you can purchase zuPOO as a single purchase or sign up for a subscription membership which takes 15% off all orders. zuPOO is also sold in UMZU’s Gut Health Bundle, combining this supplement with Floracil50 and zuACV to replenish your digestive system with prebiotics and probiotics for healthy gut maintenance in the long term.

UMZU provides free shipping on any order over $99.

Is zuPOO a good value?

zuPOO is among the higher-end all-natural laxative supplements in terms of price. However, as this is not a product intended for everyday long-term use, we found its primary value in its scientifically backed ingredients and transparency.

For instance, Gaia Herbs sells a Natural Laxative for $19.99, which shares some (but not all) ingredients with zuPOO. Its primary components include organic senna leaf and aloe juice powder, but it lacks the potent cascara sagrada that zuPOO has. Puritan’s Pride sells low-cost Herbal Laxative Tablets for just $8.99, but it is less transparent in its ingredients and provides little scientific research to back them up.

Ultimately, we found zuPOO to be a good value and a cost-effective choice for an all-natural supplement with a blend of potent botanical laxatives. We trust the UMZU brand and recommend enrolling in its subscription plan for the Digestive Health Bundle for the savings that it offers.

Quality: How well does the company deliver its core service(s) to the customer? For testing services, does the company adhere to the latest and most advanced testing technologies and achieve a very high degree of accuracy? For non-testing telemedical or teletherapy services, is the quality of the service high enough that we would recommend it to loved ones without hesitation? If not, why not? For health products, does the product or device meet a high level of safety? Is it manufactured with high-quality standards? Has it – or have its ingredients – been subjected to studies that confirm effectiveness?

User-friendly: How intuitive and convenient is the service or product? Does the device, program, app, or website achieve a good degree of user-friendliness for its customers?

Value: Are you getting your money’s worth? Are there any hidden costs or charges? Does the company offer discounts?

Privacy: If health data is stored, will your data be stored securely? Are payments secure? Does a company market your information?

Customer support: Particularly in situations where ‘one size fits all’ doesn’t make sense, how well does the company help make the service or product ideal for you or address your individual needs?
