Digestive Enzyme Formula


It’s well-known that to have a healthy body, one must consume the proper diet.

But one of the key factors in gaining and maintaining health is determined by our body's ability to breakdown, digest and utilize the foods we eat. This process is not only the building blocks used to build, repair, and maintain a healthy body, but our digestive tract is our body’s first line of defense against toxins and disease-causing microorganisms.

Therefore, it is imperative to protect and maintain our digestive system, and the first step is to ensure that our body has the ability to properly begin the digestion process in the stomach.

Digestive enzymes play a crucial role in breaking down the food we eat into smaller, more absorbable components. These enzymes are naturally produced by our bodies, but certain factors such as age, health conditions, and dietary choices can impact their production and effectiveness. Fortunately, supplementing with specific digestive enzymes can help enhance digestion and improve nutrient absorption. In this guide, we will explore the benefits and functions of the enzymes contained in Dr. Tennant's® Digestive Enzyme Formula.  It's a comprehensive list but let's dive in!


  • Embarrassing gas, bloating or digestion discomfort
  • Constipation or diarrhea
  • Sensitivity to dairy and grains
  • Irregular bowel habits or loose stool 
  • Odorous bowel movements

If you have, you would not be alone. Digestive issues are on the rise and our current food sources and consumption of processed foods only contributes to the rising issues.

So where do digestive enzymes come in? Without enzymes, our body is unable to break down food for use. This results in malnutrition and digestive problems which can easily manifest as the symptoms listed above.

When you lack strong digestive enzymes, your body has to work harder to digest the same amount of food as a person with normal enzyme production.


Enzymes are the “Biochemical Activity Assistants” of the body that stimulate processes to occur in all living cells. Without enzymes, life-sustaining processes would slow considerably and even stop.

The human body contains more than 3,000 different enzymes that function in chemical reactions, metabolism, digestion, immune response, and many other cellular processes. Enzymes are considered catalysts of biochemical reactions. Each enzyme in the body has a very specific job to accomplish and rarely has multiple functions. If an enzyme necessary to catalyze a given reaction is deficient or not available, that reaction cannot take place.


Digestive enzymes are the “Biochemical Activity Assistants” that assist in breaking down the food we eat. Food is composed of proteins, fats, carbohydrates, and fibers. Enzymes initiate change on food by breaking down each of these into progressively smaller components until they reach their basic building block form that can be used by the body. The body uses these building blocks to rebuild and heal itself, supply energy and remove toxins.


Let's dive Into each of the 27 powerful enzymes in Dr. Tennant's® Digestive Enzyme Formula.

Pancreatin 10x: Boosting Enzyme Production

Pancreatin is a combination of enzymes produced by the pancreas, including proteases, lipases, and amylases. This supplement can be beneficial for individuals with pancreatic insufficiency, a condition characterized by insufficient production of digestive enzymes. By providing a concentrated source of enzymes, pancreatin aids in the breakdown of proteins, fats, and carbohydrates, improving overall digestion and nutrient absorption.

Full-Spectrum Protein Digestive Blend

Proteases, Papain, Bromelain,

Proteases, such as neutral bacterial protease and peptidase, are enzymes that break down protein into amino acids. Proteases break down protein into progressively smaller units. Eventually, protein is broken down into amino acids, which are the building blocks of proteins that the body easily utilizes.


Dr. Tennant’s® Digestive Enzyme Formula contains protease enzymes that are effective in a wide pH range and even include powerful proteases that address difficult to digest proteins, such as gluten and casein.

Papain and Bromelain: Natural Plant Enzymes

Our full-spectrum protein digestive blend contains Papain and Bromelain. Papain, derived from papaya, and bromelain, extracted from pineapple, are proteolytic enzymes known for their ability to break down proteins. These natural plant enzymes help improve digestion and reduce symptoms of bloating and indigestion. Additionally, papain and bromelain possess anti-inflammatory properties, making them useful for individuals with inflammatory digestive conditions.

Trypsin and Chymotrypsin: Optimizing Protein Breakdown

Trypsin and chymotrypsin are pancreatic enzymes specifically involved in protein digestion. These enzymes work synergistically to break down proteins into smaller peptides. By supplementing with trypsin and chymotrypsin, individuals with compromised pancreatic function or protein digestion issues can enhance their ability to efficiently digest dietary proteins.

Peptidase: Completing the Protein Digestion Process

Peptidase is an enzyme that further breaks down peptides into individual amino acids. This enzyme ensures that protein digestion is completed, allowing for optimal absorption of amino acids in the small intestine. Supplementing with peptidase can be beneficial for individuals with impaired protein digestion or malabsorption issues.

Aspergillopepsin: Assisting with Protein Digestion in Low Stomach Acid Conditions

Aspergillopepsin is a combination of fungal protease enzymes. It is particularly useful for individuals with low stomach acid levels, as it can assist in protein digestion when the natural stomach acid production is insufficient. Aspergillopepsin aids in breaking down proteins and supports proper nutrient absorption.

Alkaline Protease: Balancing pH Levels for Optimal Digestion

Alkaline protease is an enzyme that functions in alkaline environments. It aids in the digestion of proteins in the small intestine, where the pH is higher compared to the acidic environment of the stomach. Supplementing with alkaline protease can be beneficial for individuals with reduced pancreatic enzyme production or those who require additional support for protein digestion.

What Happens if My Body Does Not Breakdown Proteins?

It is very important to break down protein and the incomplete breakdown of proteins can result in the development of food allergies.

Food allergies can develop when food is not broken down completely by our bodies. For example, amino acids are produced when larger protein molecules are broken down. If these larger protein molecules are not broken down completely to amino acids, these partly digested protein molecules can enter the bloodstream and the body sees these substances as foreign, resulting in allergic/adverse reactions.

The incomplete breakdown of proteins can result in the presence of an ammonia smell detected in urine. With incomplete digestion, meat fibers may be present in stool along with a foul odor.

Difficult to digest proteins, such as gluten and casein proteins, can create an opiate peptide excess resulting from these incompletely broken down peptides. This may result in some physical and/or behavioral issues.

Breaking Down Fats, Carbohydrates & Fiber

Carbohydrases: Carbohydrates – Sugars & Starches

Dr. Tennant’s® Digestive Enzyme Formula contains Carbohydrases, such as amylase, lactase, and invertase. These are enzymes that break down carbohydrates and starches.


Incomplete breakdown of carbohydrate-containing foods causes intestinal gas (flatulence), painful cramping, and bloating.

Cellulases and Other Fiber Enzymes: Fiber Foods

Dr. Tennant’s® Digestive Enzyme Formula includes the cellulase enzyme, which helps to break down fiber foods. This enzyme is not naturally produced in the body and, as a result, it must be supplemented orally. Noticeable undigested food fiber in the stools (e.g. undigested vegetable parts) are present without cellulase activity.

Lipases: Fats – Fatty Acids - Facilitating Fat Digestion

Lipase is an enzyme responsible for breaking down dietary fats into fatty acids and glycerol, which are easier for the body to absorb. This enzyme is primarily produced in the pancreas and plays a crucial role in fat digestion and absorption. Supplementing with lipase can be beneficial for individuals with pancreatic insufficiency or conditions that impair fat digestion.

Dr. Tennant’s® Digestive Enzyme Formula contains Lipases. These are enzymes that break down fats and oils. Long-term malabsorption of fat caused by a deficiency of the lipase enzyme results in a deficiency of fatty acids the body needs. Additionally, many vitamins and other nutrients are better absorbed along with fats.


Oily (greasy) stools contribute to a rancid and foul smell of the stool. Tan or gray colored stools are also an indication of fat malabsorption problems, as are foamy stools.

Amylase and Glucoamylase: Carbohydrate Breakdown

Amylase and glucoamylase are enzymes involved in carbohydrate digestion. Amylase helps break down complex carbohydrates into simpler sugars, while glucoamylase further breaks down complex sugars into glucose. By supplementing with amylase and glucoamylase, individuals with carbohydrate digestion issues can improve their ability to break down and absorb carbohydrates effectively.

Lactase: Lactose Intolerance Relief

Lactase is an enzyme specifically designed to break down lactose, the sugar found in dairy products. Individuals with lactose intolerance lack sufficient lactase production, leading to digestive discomfort when consuming dairy. Supplementing with lactase enzymes can help these individuals digest lactose and alleviate symptoms such as bloating, gas, and diarrhea, enabling them to enjoy dairy products more comfortably.

Alpha-Galactosidase: Tackling Complex Carbohydrates

Alpha-galactosidase is an enzyme that targets complex carbohydrates, such as those found in beans, legumes, and cruciferous vegetables. These complex carbs can be difficult to digest, leading to bloating and gas. Supplementing with alpha-galactosidase can help break down these complex carbohydrates, reducing discomfort and promoting better digestion.

Beta-Glucanase: Breaking Down Dietary Fibers

Beta-glucanase is an enzyme that assists in the breakdown of beta-glucans, a type of fiber found in oats, barley, and certain fungi. This enzyme helps break down the beta-glucan structure, allowing for better absorption of nutrients and promoting digestive health. Supplementing with beta-glucanase can be beneficial for individuals with difficulty digesting high-fiber foods.

Cellulase and Hemicellulase: Unlocking Fiber Potential

Cellulase and hemicellulase are enzymes that specifically target plant cell walls, breaking down cellulose and hemicellulose, respectively. These enzymes help unlock the nutritional potential of dietary fiber, promoting better digestion and nutrient absorption. Supplementing with cellulase and hemicellulase can be particularly helpful for individuals on high-fiber diets or those with fiber-related digestive issues.

Xylanase: Digesting Complex Carbohydrates in Grains

Xylanase is an enzyme that targets the complex carbohydrates found in grains, such as wheat, rye, and barley. This enzyme helps break down the structure of these carbohydrates, aiding in their digestion and promoting nutrient absorption. Individuals with gluten sensitivity or difficulty digesting grains may benefit from supplementing with xylanase.

Phytase: Unlocking Nutrients in Seeds and Nuts

Phytase is an enzyme that aids in the digestion of phytic acid, a compound found in seeds, nuts, and grains. Phytic acid can bind to minerals, making them less available for absorption. By supplementing with phytase, individuals can enhance the release of minerals from phytic acid, improving nutrient absorption and utilization.

Invertase: Breaking Down Sucrose

Invertase is an enzyme that breaks down sucrose, a common disaccharide found in table sugar and many sweet foods. This enzyme converts sucrose into its component sugars, glucose and fructose, facilitating their absorption in the small intestine. Individuals with difficulty digesting sucrose may benefit from supplementing with invertase.

Pectinase: Assisting in Fruit Digestion

Pectinase is an enzyme that helps break down pectin, a complex carbohydrate found in fruits. This enzyme aids in the digestion of fruits, allowing for better nutrient extraction and absorption. Individuals with fruit intolerance or difficulty digesting fruits may find pectinase supplementation helpful in improving their digestion.

Diastase: Enhancing Starch Digestion

Diastase, also known as amylase, is an enzyme that specifically targets starches. It helps break down complex starch molecules into simpler sugars for easier absorption. Individuals with starch intolerance or impaired starch digestion can benefit from supplementing with diastase to optimize starch breakdown.

Enzymatic and Digestive Support

Betaine HCl: Supporting Stomach Acid Production

Betaine HCl is a compound that supports the production of stomach acid, a crucial component in the digestion process. Adequate stomach acid is necessary for the activation of digestive enzymes and the breakdown of proteins and other nutrients. Supplementing with betaine HCl can help individuals with low stomach acid levels improve overall digestion and nutrient absorption.

Ox Bile Extract: Enhancing Fat Digestion

Ox bile extract is a supplement derived from the bile of cows. It contains bile acids, which play a vital role in the digestion and absorption of dietary fats. Supplementing with ox bile extract can support fat digestion, particularly in individuals with reduced bile production or those who have had their gallbladder removed.


Enzymes are substances that make life possible and the key to unlocking good health and vitality. Without enzymes, our bodies would not be able to harvest the nutrients from the foods we eat. They are the manual workers that help build and repair the body from proteins, carbohydrates, and fats.

Before we can help you decide, let's share with you the process of how your body works.

The digestion of food takes place in stages: beginning in the mouth, then moving to the stomach, and finally into the small intestine.

At each step, specific enzymes break down different types of food. The final breakdown of the remaining small molecules of food generally occurs in the lower small intestine.


Naturally occurring food enzymes and supplemental enzymes begin the process of digestion earlier in the digestive tract and improve the chances of food being more fully digested.

Raw foods, such as fruits and vegetables, are excellent sources of enzymes, but these enzymes are destroyed when the food is processed, canned, or cooked. Supplementation with digestive enzymes replaces those lost in cooking and enhances the enzymes found in raw foods.

Unfortunately, the modern diet consists of predominantly enzyme-deficient cooked foods

In the absence of supplemental enzymes, the bulk of digestion occurs in the small intestine. The chance of undigested food being absorbed into the body is increased. This absorption can cause immune responses because the body recognizes food particles in a similar manner to how it recognizes invading pathogens, something that is foreign and needs to be acted upon to protect the body from harm.

The chance of undigested food entering the colon is also increased with inadequate levels of digestive enzymes. Incomplete digestion of food allows colon bacteria and fungus to feed, producing gas and toxins that can leave people feeling uncomfortable and even sick.

Proper and complete digestion is essential in maintaining good health because, without digestion, the nutrients you consume from the food you eat won’t be adequately absorbed.

Optimize Your Digestion with Digestive Enzymes

Digestive enzymes also play a key role in gastrointestinal health because they can exert a powerful effect in addressing a full range of commonly recognized gastrointestinal disturbances.


Clinical experience with the use of digestive enzymes has shown that these conditions can be supported by the use of full-spectrum enzyme formulations, such as Dr. Tennant’s® Digestive Enzyme Formula:

  • Intestinal irritation
  • Food allergies and sensitivities
  • Maldigestion and malnutrition
  • Intestinal hyperpermeability
  • Gut dysbiosis
  • Vitamin and mineral deficiencies
  • Poor or impaired wound healing

  • Skin conditions
  • Behavioral problems
  • Intestinal flora imbalances
  • Abnormal growth patterns
  • Improper organ development
  • Immune system impairment leading to frequent illness

    The human body naturally produces digestive enzymes. However, the following situations can leave an individual lacking in necessary enzymes:

    Nutritional deficiency adversely impacting enzymes Enzyme production can decrease with age Cooking of foods destroys naturally occurring enzymes Many situations can cause enzyme deficiency too: Stress can deplete enzymes Illness can inhibit enzyme production Injury can overtax enzyme level. 


    Digestive enzymes have specific jobs and act only on specific types of food substrates. For example, lipase enzymes only digest fats; they do not act on protein or sugar. Sucrase enzymes only digest sugars and do not affect fat or protein. Proteases and peptidases act on protein, casein, and gluten, and other enzymes do not.

    When you are looking for a digestive enzyme supplement, you will want to look for a full-spectrum product. This will help to ensure you have all the enzymes you need. Dr. Tennant’s® Digestive Enzyme Formula provides them at professional strength to ensure we get the most out of taking an enzyme supplement.
