DigestShield® (formerly GlutenShield) is the world’s first Co-Probiotic™ that contains prebiotics, probiotics, and enzymes. It works by breaking down gluten, dairy, fats, carbohydrates and protein into small pieces for your body to use, shielding against possible effects such as inflammation and discomfort. It also helps to restore proper microflora balance by providing a full complement of beneficial probiotic bacteria. (15)

Just think of taking DigestShield® as a way to provide your body with everything it needs to protect itself from potential “bad actors” commonly found in our modern diet.

Digital man with shield repelling bacteria

DigestShield™ is more than just a way to protect yourself from gluten. It is the all-in-one “digestive powerhouse” that can make digestion of everything you eat better.

Sandwich and Beer DigestShield™ contains a revolutionary blend of enzymes, probiotics and prebiotics to assist with efficient digestion of gluten and other foods.

Let’s say you are having a submarine sandwich and a beer for lunch.

Gluten: DPP-IV and serrapeptase work to break down the gluten found in the bread, beer and processed deli slices. (2, 7)

Lectins: Vegetarian chitosan protects you from the wheat lectins in the bread.(12-13)

Lactose: Lactase can break down the lactose found in cheese and other dairy products. (4)

Phytates: Phytase can break the phytates found in bread and other grains into a form of phosphorus that the body can use. (6)

Cellulose: Cellulase, hemicellulase, and xylanase all break down the indigestible cellulose found in the cell walls of plants like tomatoes, lettuce and onions. (5)

Fats, Carbohydrates and Proteins: Lipase enzymes break down the fats found in the meat, cheese and condiments. Amylase breaks down the carbohydrates in the beer, vegetables and bread. Protease breaks down the protein in the meat, cheese and bread. (8)


The enzymes in our formula break down gluten, dairy, casein, carbohydrates, protein, and fat. Enzymes are biocatalysts that break the bonds of the food we eat into small enough forms for our body to use. There are many different enzymes found in the human body and they all have specific jobs. Our formulation includes a carefully chosen combination of plant-based enzymes to help you get the most from the foods you eat.

Plant-based enzymes, found in the majority of enzyme supplements, originate from plant organisms that produce acid-stable enzymes.These enzymes are purified and characterized which means their pH is well known and easily determined. Most of these enzymes can work in a pH range of 2 to 9 without loss of activity.1  This means our blend of enzymes will survive the harsh acidic environment of your stomach. Here is the line-up of enzymes in DigestShield® and what they do:


Dipeptyl peptidase IV (DPPIV) is a protease class enzyme shown to have hydrolytic capacity for breaking down gluten. This means that DPP-IV can break the toxic protein, gliadin into harmless constituents before an immune response is triggered.2 Humans do produce this enzyme, but often in insufficient quantities required to break down gliadin molecules enough to prevent binding.3 We include DPP-IV to supplement the amount we naturally produce and provide relief from gluten related health issues.


Lactose is a disaccharide found in milk and other dairy products. Each lactose molecule is composed of a galactose molecule and a glucose molecule bound together. The enzyme, lactase, is required to cleave the bond between these two so that the body can use the individual glucose and galactose molecules. However, many people stop producing this enzyme after the age of two. This enzyme deficiency prevents the breakdown of lactose, which can often lead to gas, bloating, and intestinal pain after consuming milk and other dairy products.4 We have included a dose of lactase in DigestShield™ to break this sugar down for use before it causes any problems.

Cellulase, Hemicellulase, and Xylanase

Cellulose is found in the cell walls of all plants and unfortunately, humans lack the necessary enzymes required to break them down. Usually, since the cellulose will pass through the stomach and small intestine intact, the bacteria in the large intestine will ferment it. This allows us to use some of the energy available from cellulose but it can produce a lot of gas in the process, which can lead to bloating or passing gas. cellulase, hemicellulase, and xylanase all break down cellulose before they reach the large intestine.


Phytic acid is the storage form of phosphorus found in many seeds, cereals, and plant oils. When consumed, it has been shown to bind to essential minerals such as iron, zinc, and calcium. The resulting mineral compound is too large to be absorbed and can lead to nutrient deficiencies.6 Bacteria found in the gut of ruminant animals like cows produce phytase but we do not.6 We include phytase to cleave the bonds of phytic acid, releasing the phosphorus in a useable form and preventing it from causing mineral deficiencies.


This is another protease class enzyme that helps break down proteins. It is not naturally found in the human body but as a supplement, serrapeptase has been shown to reduce inflammation.7

Plant-Based Digestive Enzymes

Lipase, protease, and amylase are terms for the general categories of enzymes that break down fats, proteins, and carbohydrates, respectively, into small enough particles for absorption in the gut. We include a full complement of plant-based lipase, protease, and amylase enzymes to help you digest and absorb all of the foods in your diet.8

Prebiotics is the term used to refer to fermentable carbohydrates which stimulate and nourish probiotics and beneficial bacteria strains in the large intestine. They serve as a substrate and food for the good bacterial colonies there.9 DigestShield® contains a proprietary mixture of prebiotics and herbs chosen to support the probiotics included in our formula.

Chitosan Oligosaccharide

Chitosan Oligosaccharide in our formula serves the dual purpose of both prebiotic and lectin decoy. Plant lectins are anti-nutrient proteins found in many foods we eat including grains such as wheat. Lectins bind to cells in our digestive tract because of the sugar coating, or glycocalyx that surrounds each cell. Different lectins have been shown to have different attraction to specific sugars.10 Wheat lectin, known as wheat germ agglutinin (WGA), has been demonstrated to have a sugar-binding attraction to N-acetyl-D-glucosamine, meaning it will bind to that sugar whenever possible.11

Chitosan is a natural source of N-acetyl-D-glucosamine. By substantially including it in the DigestShield® formula, we are providing a decoy to which the dangerous lectins in your diet can bind. This means that instead of binding to your gut wall and causing damage, the lectin can bind to our chitosan and be harmlessly carried out of your body during a bowel movement.12-13

Our mushroom derived chitosan is the first ultra-low molecular weight (3000 Dalton) product of its type in the world. Most sources of N-acetyl-D-glucosamine are derived from shrimp and crab shells. Our chitosan is derived from the cell wall of the oyster mushroom. Additionally, the chitosan in DigestShield® is several orders of magnitude smaller (on a molecular scale, not a dosage scale) than any other on the market. This is referred to as Ultra Low Molecular Weight (ULMW) and provides a much greater binding potential. It addresses harmful wheat lectins, potato lectins, lectins found in nightshade vegetables, and is capable of binding lipids in the diet to reduce absorption.

Fructooligosaccharides (FOS)

Short-chain FOS serves as a substrate for gut bacteria and is metabolized to short-chain fatty acids. This can lead to lowering the pH in the gut environment and promote calcium absorption.13

Alfalfa Powder

Alfalfa is a rich natural source of prebiotics that can promote the growth of beneficial bacteria.14

Probiotics are live bacteria and yeast that are beneficial to health. Though we do not yet have complete understanding of the full scope of the mechanism that these organisms exert on human health, researchers have studied many strains and found them to have beneficial effects.15
