A healthy digestive system affects all aspects of our overall wellness. Issues like constipation, diarrhea, bloating, and gas are not only uncomfortable – quite often, they are problems that also impact our mental and emotional health, hormonal balance, and cellular communication. After all, if your gut is not functioning optimally, you can’t properly process the nutrients you’re putting into your body.

What is Floracil50?

Floracil50 is a dietary supplement manufactured by UMZU for digestive health. This extra-strength probiotic formula supplies 50 billion CFUs (colony-forming units) of eight strains of microorganisms that support gut function and, ultimately, your overall mental and physical wellbeing.

Founder Christopher Walker established UMZU in 2015 after achieving personal success in treating the effects of a pituitary gland tumor he developed while studying neuroscience at Duke University. Walker’s published findings led to his eventual development of all-natural hormone-balancing supplements for women and men.

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

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

Does Floracil50 work?

Floracil50 is an effective probiotic supporting healthy digestion and promoting better mental and physical wellness. The Lactobacillus strains in Floracil50 supply your intestines and genitals with beneficial bacteria that may improve gut health, immunity, and hormonal balance.

In our trial of Floracil50, we experienced overall health improvements, including better mental focus, smoother digestion, and boosted energy. We felt many of the advertised positive effects of this supplement and recommend it for most people who want a gentle but impactful daily probiotic boost.

We also recommend consulting with your doctor before starting any new supplement regimen. Some people in particular need to be the most careful. If you take short- or long-term medications or are pregnant or nursing, proceed with caution and talk to your doctor first. Lastly, if you have ongoing issues like chronic diarrhea, constipation, or bloating, turn to your doctor first on your path toward treatment.

How Floracil50 works

Floracil50 supports the immune system and gut health by helping establish a healthy microbiome, an internal bacterial community contributing to digestion and general wellness. By supplying the body with eight strains of microorganisms, Floracil50 helps diversify your gut bacteria and reduces issues like diarrhea, constipation, bloating, and flatulence.

Each bottle of Floracil50 contains a 1-month supply (30 capsules), which you take once daily with a meal. Initially, you may experience minor stomach discomfort as your body adjusts to the new regimen. If your side effects are minimal, they should pass within a couple of days. If you experience ongoing or more severe side effects, discontinue use and consult your doctor.

Below, we’ll look at some of the primary components in Floracil50 and how they work together to improve digestive health.

Lactobacillus casei

Lactobacillus casei are widely studied bacteria based on their health benefits and natural occurrence in foods like fermented fruits and vegetables. Dairy manufacturers employ these types of bacteria in fermenting products like sour cream and yogurt. Recent meta-analyses of L. casei studies have demonstrated its benefits in enhancing immunity, brain function, pathogen resistance, and barrier function. It also demonstrates anti-cancer activities.

Lactobacillus acidophilus

Lactobacillus acidophilus is another widely studied bacteria for treating digestive disorders. Researchers have examined L. acidophilus for use in treating acute, chronic, and antibiotic-associated diarrhea. They’ve concluded that it’s safe to use, even in cases of immunosuppression.

Lactobacillus plantarum

This beneficial bacteria shows promise for promoting gut, brain, and metabolic health and treating obesity, inflammation, irritable bowel syndrome (IBS), diabetes, and psychological disorders.

Bifidobacterium infantis

As its name implies, Bifidobacterium infantis is a more dominant bacteria in children than in adults. B. infantis is associated with trophic, protective, and metabolic functions. According to researchers, this microorganism may provide a biomarker for certain diseases in the future.

Bifidobacterium longum

Bifidobacterium longum shows potential as a preventative and protective treatment for irritable bowel syndrome (IBS). It can improve immunity regulation, reduce inflammation, and alter the gut microbiota structure. Researchers have also investigated B. longum as an anti-obesity treatment, concluding that supplementation decreased body weight in animal studies. However, in human studies, B. longum did not impact BMI or weight ratio.

Lactobacillus reuteri

L. reuteri is a beneficial bacteria found in the gastrointestinal tract, skin, urinary tract, and breast milk. Its antimicrobial activity has demonstrated benefits for the immune system, inflammation relief, and the promotion of T-cell development and function.

Bifidobacterium breve

Scientists have researched Bifidobacterium breve for several reasons, but the most focus has been on using this gut microbe in preventing and treating premature birth complications in infants. This strain has demonstrated beneficial impacts on infant health and may also support the prevention and treatment of pediatric diseases.

Lactobacillus rhamnosus

Lactobacillus rhamnosus is a widely available probiotic strain found in many supplements supporting digestive health and aiding issues like diarrhea or gastrointestinal infections. Like other Lactobacillus strains, it supports immunity, brain and barrier function, pathogen resistance, and cancer prevention and treatment.

Is Floracil50 safe?

The National Institutes of Health (NIH) and other health organizations generally conclude probiotic supplements to be safe in healthy adults. Potential harmful effects typically involve consumers with compromised immune systems or severe illness. Products containing contaminants may present serious health risks.

Floracil50 is considered safe for adults over the age of 18. Consult with your physician before taking this (or any) supplement if you have a medical condition, take medication, or have a history of food or drug allergies. Floracil50 is not recommended for pregnant or nursing women.


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

In the chart below, you’ll see the individual, subscription, and bundle prices for Floracil50 side by side to see what option may be best for you. UMZU provides free shipping on any order over $99.

  One-time purchase Subscription purchase
Floracil50 $44.95 $38.21
Gut Health Bundle $109.85 $93.37

Is Floracil50 a good value?

Floracil50 provides more colony-forming units of diverse probiotic strains than almost any brand on the market. It is barely beat by 1MD Nutrition’s Complete Probiotics Platinum, which boasts 51 billion CFUs per dosage, and that product costs $5 more, at $49.99 per bottle.

Athletic Greens AG1 costs over double the price of Floracil50. While it offers a broader spectrum of botanicals, vitamins, and minerals, it provides just 7.2 billion CFUs of a less diverse probiotic community.

Ultimately, we found UMZU’s Floracil50 to be a great value based not just on its price but on its ingredient transparency, company reputation, and effectiveness. Cheaper products abound on the market shelves, but the quality of Floracil50 justifies a higher price.

How we evaluate health products and services

At Innerbody Research, we customize our evaluation criteria depending on the type and nature of the health-related service or product. But in general, for health products and services, we have five broad areas that we explore in our evaluations, including:

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?
