What is Bowel Guard?

Bowel Guard is a nutritional supplement marketed towards people with digestive issues. If you struggle with bloating, diarrhea, gas, and other digestive issues, then Bowel Guard can purportedly help.

The supplement also claims to help your body handle specific types of foods. If you struggle with dairy products, protein-rich meals, fatty meals, and gluten, for example, then Bowel Guard may be able to help.

To achieve these benefits, Bowel Guard contains a single strain of probiotic bacteria mixed with digestive enzymes like lipase, lactase, and protease.

By taking Bowel Guard daily, you can purportedly help your body digest foods and break down ingredients. The supplement can also help maintain digestive regularity, making it easier for you to poop more frequently – and enjoy higher quality poops.

Bowel Guard is exclusively available through, where it’s marketed through a dramatic sales page. That sales page describes Bowel Guard as “a revolutionary product” specially formulated by a former runner who dealt with extreme digestive issues – but was able to solve those issues with Bowel Guard.

Bowel Guard is made by a Scranton, Pennsylvania-based company named Peak Biome Inc.

How Does Bowel Guard Work?

Bowel Guard claims to eliminate diarrhea, gas and bloating using a range of digestive support ingredients.

Although Bowel Guard makes dramatic claims about the uniqueness of the formula, the ingredients list shows Bowel Guard is similar to other digestive support formulas. It contains probiotic bacteria, digestive enzymes, and other ingredients that could help with digestion in various ways.

Your body needs digestive enzymes to break down certain foods. Your body uses specific enzymes for specific foods. It uses protease, for example, to break down protein. If your body has improper levels of protease, then you may struggle to break down a protein-rich meal.

Similarly, your body needs digestive enzymes like lactase to break down the lactose in dairy. Some people have naturally lower levels of lactase, which can contribute to lactose intolerance.

If you feel bloated after a certain meal, or if you struggle with diarrhea and indigestion after eating dairy or protein-rich foods, then it’s possible a digestive enzyme supplement can help.

Bowel Guard contains seven different digestive enzymes and 3 billion colony forming units (CFUs) of probiotic bacteria. While other digestive support supplements contain multiple strains of probiotic bacteria, Bowel Guard contains just one strain (Saccharomyces boulardii).

Key digestive enzymes in Bowel Guard include lipase, lactase, peptidase, cellulase, protease, amylase, and invertase.

Some of the advertised benefits of Bowel Guard include:

  • Give you firmer poops
  • Digest fat-rich, protein-rich, or dairy-rich meals without issues
  • Promote the growth of healthy gut bacteria
  • Help with weight loss
  • Promote better energy levels

Digestive enzymes help your body extract nutrients, calories, vitamins, minerals, and other ingredients from the foods you eat. When your body has the right digestive enzymes, it can boost your energy after a meal. Your body no longer struggles to digest meals. You can easily and quickly digest foods without issue.

Bowel Guard Ingredients

Bowel Guard contains a range of probiotics and digestive enzymes targeting different health and wellness goals. We’ll explain each probiotic and digestive enzyme below because each ingredient has a different targeted effect.

3 Billion CFUs of Probiotic Bacteria: Bowel Guard contains 3 billion colony forming units (CFUs) of a probiotic strain named Saccharomyces boulardii. Peak Biome claims S. boulardii “is one of the most powerful probiotics we know of” and is “FDA-approved” and used by doctors to give patients “perfectly firm poops.” The company also cites a study showing S. boulardii has been used for 30 years to treat travelers’ diarrhea, antibiotic-related diarrhea, and other issues. Peak Biome also claims this probiotic can support a healthy immune system, reinforce your intestinal barrier, improve carb digestion, and reduce gut inflammation, among other benefits.

Lipase: Lipase is a digestive enzyme that helps your body digest and breaks down fats. Peak Biome claims it “melts fatty acids like a hot knife through butter,” giving you perfectly firm poops even when eating greasy foods. Lipase can also enhance the absorption of vitamins D, K, E, and A while delivering less gas and bloating after meals.

Lactase: Lactase is a digestive enzyme that helps your body break down lactose. A lack of the lactase enzyme contributes to lactose intolerance. Some people can’t consume dairy because they don’t have enough lactase. Bowel Guard contains lactase to help your body break down the lactose proteins in milk and other dairy products.

Peptidase with DPP: Peptidase helps your body break down gluten. Peak Biome claims many people with gluten sensitivities are not actually gluten-intolerant: they simply need more peptidase. The dipeptidyl peptidase IV (DPP-IV) in Bowel Guard could help your body break down gluten.

Cellulase: Cellulase helps break down dietary fiber, including the cellulose inside green vegetables. The cell walls of vegetables and plants are made from cellulose, and the cellulase enzyme helps your body break down these cell walls.

Protease: Protease is an enzyme that helps your body break down proteins. If you ever feel bloated after a protein-rich meal (or after a protein shake), then your body could lack enough protease.

Amylase: Amylase helps your body break down starches and carbohydrates into simpler sugars, including the sugars that give your body energy.

Invertase: The last digestive enzyme in Bowel Guard is called invertase. It helps your body turn ordinary sugar (sucrose) into glucose and fructose, helping energize your cells.

Scientific Evidence for Bowel Guard

Peak Biome has not run any studies or clinical trials on Bowel Guard to prove it works as advertised. However, the company cites dozens of third party studies performed on the individual ingredients within Bowel Guard, including studies showing the digestive enzymes and probiotics in Bowel Guard could work as advertised to support digestion.

Peak Biome cites this 2010 study, for example, showing that Saccharomyces boulardii is linked with anti-inflammatory effects. Researchers described S. boulardii as “a well-studied probiotic” that “can be effective inflammatory gastrointestinal diseases” like inflammatory bowel disease, diarrhea, and general digestive inflammation.

Similarly, this 2010 review study analyzed evidence of S. boulardii and found it to be a safe and effective probiotic strain. Researchers cited dozens of studies performed between the 1970s and 2000s and found that S. boulardii was “significantly efficacious and safe in 84%” of trials. In other words, S. boulardii is a proven and powerful strain of probiotic bacteria.

The digestive enzymes in Bowel Guard are well-studied and linked with various benefits. As this 2008 study showed, for example, protease is a multifunctional enzyme in life and disease, linked with a range of benefits and functions throughout the body.

Similarly, this 2018 study analyzed the effectiveness of lactose intolerance supplements like lactase enzymes. Researchers concluded that you could manage lactose intolerance through lactase supplements. After analyzing the available evidence, researchers found a significant connection between lactase supplementation and reduced symptoms of lactose intolerance.

Overall, the ingredients in Bowel Guard should work as advertised to boost digestion, support more regular bowel movements, and help your body break down foods and ingredients.
