Dr. Tennant’s® Microbiome Support


Like You, thousands of others have found this page because they have searched far and wide on a Quest for Improved health.

But for many, the Diets and Mounds of Dietary Supplements that were started with high hopes of success, provided little to no benefit in the end!

Please take a moment to answer these 6 questions:
  • Have you ever taken an antibiotic at any time in your life?
  • Have you ever used Splenda, even once?
  • Have you, or do you, consume commercially raised meats, beef, chicken, pork, and dairy products?
  • Do you experience stress on a regular basis?
  • Are you overweight and can’t seem to lose weight no matter what you try?
  • Do you experience overwhelming cravings for foods that do not support a healthy weight?
  • Do you eat grains like wheat, corn, and rice?

If you answered YES to any of these questions, then you’re in the right place.

Our Gut Microbiome is Like a Garden

Did you know that 70% of your ability to fight infection and stay well, basically your immune system, comes from your gut, and is sometimes even refered to as our  2nd brain. The reality is that the gut is a key portion of not only our digestive tract where we process food, but its ability to function impacts our overall health.

The health of your digestive tract affects your mood, food cravings, irritability, brain health, hormone regulation and yes, your immune systems too.


So how healthy is your gut? Or another way to say this is, “How are you feeling?”

Imagine a beautiful garden with lots of vibrant colors and fruits and vegetables. This garden is beautiful, but it takes work: weeding, water, sunlight, attention, and care. When not watered or cared for, the garden quickly changes and becomes overgrown and full of weeds. This is not unlike what happens in our gut. 

Our microbiome requires similar care, attention, and nutrition. Our microbiome needs good food (probiotics), fertilizer (food for the probiotics known as prebiotics), and support (something to get rid the weeds and help detox the gut). When not cared for, dysbiosis can occur (imbalance of bacteria in the gut) and cause additional changes in food cravings, irritability, mood, or stress management.

Now let’s take a closer look at what might affect the overall health of the microbiome.



If you have taken an antibiotic before, you may be surprised to learn just a single round of strong antibiotics can destroy 100% of all the beneficial bacteria in the intestinal tract (aka the “gut”)!

These beneficial bacteria are essential to your health. We are alive and prosper because of the actions of these “good bacteria”. Without them our health suffers. 

Here are some things you may not already know:

  • Beneficial bacteria make up nearly 80% of our immune system!

  • They also help us digest food for energy and they manufacture vitamins and other substances that support our health and wellness.

  • They help with mood management and so many other important functions.

In fact, it can take up to two years for these beneficial bacteria to re-populate and the microbiome to start to function more normally after a round of strong antibiotics.  This is especially true when considering the return of the diversity and balance of organisms.

But keep in mind, the health of our beneficial bacteria is only a part of the whole story.


Use of Splenda and Artificial Sweeteners

If you have ever used Splenda, you may also be surprised that just one packet of Splenda–yes, the artificial sweetener that many people think is the “safe one” –can destroy up to 50% of the beneficial bacteria in the gut!

If you are trying to cut down on sugar–an excellent idea for GI health too–using substitutes like Splenda, Aspartame (Equal), etc. are not a healthy alternative. Try using organic stevia leaf, its extract, or monk fruit instead. You may need to shop the brands to find the one you like, but it is well worth the effort!


Antibiotics Are Everywhere

Many people think, “I haven’t had an antibiotic for years, so I am OK.” Right? Well…

If you eat commercially raised meats like beef, chicken, pork and use dairy products, you are getting a continuous dose of antibiotics every time you eat these foods. 

In fact, 80% of all antibiotics manufactured in the US go into commercially raised meats and dairy.

This means that these beneficial “good” bacteria are continually exposed to antibiotics. They never stand a chance to maintain levels that are required to support a strong immune system and maintain good health. 

Interestingly, natural casings to make sausage are derived from the GI tract of livestock. The GI tracts of US livestock can often lack integrity because our cattle (like many of us) suffer from “Leaky Gut”. These can’t be used to make casings. Often casings must be imported primarily from Argentina or New Zealand where cattle are more organically raised, and antibiotics are not used.


Chronic Stress

Stress, especially chronic stress, increases intestinal permeability and GI dysfunction. Most of us live in a constant state of stress (fight or flight) and it is so normal that we don’t even realize it or notice it anymore.

Stress turns off normal digestive functions (part of the parasympathetic system) because the body’s resources are hard-wired to support and turn-on “stress-state” activities (sympathetic system) that enable the body to meet the real or perceived dangers in the fight-or-flight stress response. These include an increased heart rate and blood pressure leading to increased blood flow to the skeletal muscles to support running. The GI muscles relax, and digestive enzymes as well as stomach acid aren’t produced.

This fight-or-flight stress worked well for our caveman ancestors who had periodic moments of running for their lives from a Saber Tooth Tiger. They needed all the resources the body could muster for survival and avoid becoming a meal rather than trying to digest last night’s meal. 

Obesity and Overwhelming Food Cravings

Anything that tips the balance of our microbiome to favor “bad bacteria” will result in unhealthy food cravings (sweets, starches, carbohydrates) which can eventually lead to obesity.

Important concept – “Bad” bacteria thrive on sugar, carbs, starches, and fats; however, “Good” bacteria thrive on vegetables, fruit, and fiber.

Did you know “Bad bacteria” send messages to our brain to eat foods they crave which are starchy, sugary, fatty foods that promote their health, not ours? If you experience overwhelming food cravings for sweets, breads, pasta, and fried foods, this could be why. Your microbiome is out-of-balance where “bad” bacteria are in charge.

Stress and antibiotic exposure tip the balance to favor “Bad Bacteria” too.

Shifting the Balance favoring good bacteria can help us maintain a healthy weight. Good bacteria turn off these messages that compel us to eat more food, especially the type of food that makes us gain weight and lead to obesity.

Many people find it easier to manage their weight by eating more foods high in fiber or take a high-quality fiber supplement. Our bodies can’t digest the fiber, but the “good” bacteria can–it is their primary food–and when the fiber is in abundance, their colonies thrive.

Hidden GMOs

If you are like most people, you probably eat bread and corn or consume foods that contain wheat or corn. If you eat processed foods at all, this likely applies to you.

Eating grains – corn, wheat and other GMO crops are laced with round-up

Did you know that when you eat commercially grown grains like wheat and corn you are also likely getting a steady dose of “RoundUp”?

That’s right, the same chemical you can buy at your local home and garden store to kill weeds.

You probably have never imagined drinking “RoundUp” have you? 

Glyphosate–the active ingredient in “RoundUp”–is the choice for weed control used in the farming of wheat and corn, along with other grains and GMO crops.

GMO crops have been modified to withstand treatment with RoundUp, so only the weeds die and not the crop.


Bacteria (our microbiome) and RoundUp

RoundUp kills weeds but also kills bacteria. Bacteria also die because–like plants–they too are affected by RoundUp.

Americans are now getting a steady dose of Round-Up when they consume these crop foods. These residues also affect the beneficial bacteria that are supposed to flourish in our GI tracts and keep us flourishing too. Our bacteria, that comprise our microbiome, are sensitive to RoundUp just like normal (non-GMO) plants.


Intestinal Integrity and RoundUp

Additionally, Glyphosate in RoundUp–like many other toxins–affects the tight junctions that hold the cells in the GI tract together. These tight junctions are found in between cells.

Exposure to Glyphosate not only kills the bacteria in our GI tract, but it also promotes “Leaky Gut” because it weakens the tight junctions that hold the cells in our GI tract together.


Leaky Gut: Is This Really a Problem?

Without the beneficial bacteria, normal mucosal (mucus) lining, and intestinal cell junctions functioning properly, our gut lining begins to fail and leak.

A "Leaky Gut" can allow food particles, toxins, and bad microbes inside our bodies.

Toxins and pathogens travel throughout our body in our blood streams and can wreak havoc.  So why should we care if our epithelial cells lining the GI tract are letting a few undigested proteins, food particles or microbes through?

We should care because intestinal permeability is a major contributing factor to inflammatory diseases, including gastrointestinal problems such as Celiac Disease, Ulcerative Colitis, Crohn’s Disease, Inflammatory Bowel Disease, and Irritable Bowel Syndrome; as well as metabolic diseases, such as obesity, fatty liver disease, diabetes, and cardiovascular diseases.

Did you know most chronic disease is associated with a “toxic, dysfunctional and leaky gut”?

Chronic/Inflammatory diseases and other health concerns related to Leaky Gut include:

  • Diabetes
  • Obesity
  • Heart Disease
  • Weight Management Problems
  • Auto-Immune Conditions and Responses
    in the Thyroid and Joints
  • Celiac Disease, Ulcerative Colitis, Crohn’s Disease, Inflammatory Bowel Disease, Irritable Bowel Syndrome
  • Allergies
  • Cancer
  • Chronic Pain/Inflammation

Autoimmune Disease and Immune Health

Because the gut barrier is a crucial part of the immune system (in fact the majority of your immune system is located in the gut), dysfunction here can cause immune problems including autoimmune disorders.

One major study states: "There is growing evidence that increased intestinal permeability plays a pathogenic role in various autoimmune diseases including Celiac Disease and Type 1 Diabetes… besides genetic and environmental factors, loss of intestinal barrier function is necessary to develop autoimmunity."

  • Visser J1, Rozing J, Sapone A, Lammers K, Fasano A., Tight junctions, intestinal permeability, and autoimmunity: celiac disease and type 1 diabetes paradigms. Ann N Y Acad Sci. 2009 May;1165:195-205. doi: 10.1111/j.1749-6632.2009.04037.x.


The study goes on to explain that intestinal permeability is a trigger for autoimmune disease because when unwanted pathogens and proteins cross the gut barrier, your body mounts an immune attack against them.

This immune reaction can trigger an autoimmune response in people who are already genetically susceptible and in places outside the gut such as joints and the thyroid gland.

  • M C Arrieta, L Bistritz, and J B Meddings; Alterations in intestinal permeability. Gut. 2006 Oct; 55(10): 1512–1520. doi: 10.1136/gut.2005.085373


Leaky gut is also associated with gut flora dysfunction (“good vs bad” bacteria or Microbiome balance). Gut dysbiosis has been linked to many problems from acne to depression to constipation.


Basically, the bottom line is…if your gut isn’t happy, you won’t be happy either.

So, now you know…

Your search for improved health will never end until you improve the health of your gut first!

Fortunately, people are now starting to realize that health truly begins in the gut. Most practitioners would agree this is true and are starting to approach their patients from the standpoint of Healing the Gut First!


Dr. Tennant’s® Microbiome Support

Help Keep your gut barrier healthy!

Dr. Tennant’s® Microbiome Support with its researched and clinically proven ingredients supports these important aspects of GI health:

  • Stronger intestinal barrier support and improved GI cellular tight junction function. Mucosal Barrier support. Increased natural “good bacteria” SCFA production–such as butyrate–and phospholipids to help heal the GI tract.
  • Proven Immune System support and immune modulatory elements for a healthier immune response.
  • A superior group of high-molecular weight, stable prebiotic fibers proven to enhance a natural, healthy Microbiome flora in the GI tract. Fibers also naturally improve detoxification and promote Weight Management by providing a feeling of fullness. Fiber supports a normal Microbiome balance which prevents “bad bacteria” from sending messages to the brain to overeat the wrong foods which further supports weight management.
  • Potent antioxidant and soothing, effective anti-inflammatory support with several powerful ingredients to help reduce inflammation and inflammatory responses throughout the GI tract.
  • Helping to provide relief with more normalized bowel habits, as well as detoxification support in binding, shuttling, and eliminating toxins through the colon.

Introducing Dr. Tennant’s® Microbiome Support’s line-up of comprehensive GI health support “all-star” ingredients. Let’s take a closer look.


Let's Look at some of the ingredients:

Lignite Extract 

Properly extracted Lignite Extract has been shown to provide the redox capacity, electrochemical balance, energetic support, antioxidants, ancient plant material metabolites, and potent detoxification actions that can help restore and support intestinal barrier integrity, tight junction function, and optimum GI Health.

IMMULOX® - Proline-Rich-Polypeptides (PRP) enriched Colostrum

IMMULOX® - Proline-Rich-Polypeptides (PRP) enriched Colostrum providing advanced natural, clinically proven, immune response modulation and immune factor support in the gut.

IMMULOX® Colostrum is a powerful ally to help balance immune system activity and naturally.

Immulox® Colostrum’s Growth Factors also help accelerate the healing and restoration of GI tract tissues damaged by inflammation.

PROPOL A® - Propol/Glucomannan Prebiotic Fiber

Propol A® - Propol/Glucomannan Prebiotic Fiber is a clinically proven, highly-purified, prebiotic fiber with the longest chain, highest molecular weight glucomannan fiber in nature.

Propol A® fiber is also the most stable glucomannan fiber available and PropolA® doesn’t degrade in GI conditions allowing it to provide support for optimal environmental conditions in the GI tract.

Propol A® is clinically proven to support healthy weight management due to its ability to impart satiety and to improve microbiome balance. “Bad bacteria” thrive on sugar and other foods like bread that can be digested into sugar. They actually send messages to our brains that cause overwhelming cravings to eat the foods that make weight management difficult. “Good bacteria” digest Propol A® because their primary food is fiber.  Most people notice a marked decline in food cravings as the microbiome is more balanced and the "good bacteria" prevail.

Propol A® is the best prebiotic available for the thousands upon thousands of “good” probiotic strains that occupy the GI tract and support our overall health and wellness.

In fact, Propol A® has been proven to increase Bifidobacterium colonies by almost 17% in just 30 days (the Bifidobacterium group is a major “good” bacteria group that supports many aspects of human health). Additionally, the study measured changes in markers of “good bacteria” activity such as SCFA production, stress management support and neurotransmitter production.

ResistAid™ - Larch Arabinogalactan Extract

ResistAid™ is Larch Arabinogalactan Extract (Larix occidentalis).  Arabinogalactans are soluble fibers found in many plants but occur in particularly high concentrations in the larch tree.

Arabinogalactans are thought to offer a number of health benefits especially due to the ability to support a healthy and thriving microbiome.

Larch arabinogalactan is thought to stimulate the immune system in part by increasing intestinal levels of native bacteria known to play a key role in immune function and protect against the common cold, influenza, hepatitis C, HIV/AIDS, and other types of viral and bacterial infections. Immune support is three-fold: direct, indirect, and through antioxidant capacity.

In addition, larch arabinogalactan is said to help with the following:

  • Autoimmune disorders
  • Constipation
  • Liver Health
  • Dry Eye Syndrome
  • Immune Support
  • Weight Management
  • High Cholesterol
  • Inflammation


CurQfen® is a Powerful antioxidant and soothing, effective anti-inflammatory support with a patented, Bioavailable formula. 

CurQfen® is different from any curcumin formulated product available today. As many as 95% of curcumin products on the market are not well absorbed by the body and instead pass straight through the GI tract without being absorbed and used by the body,

CurQfen® is a unique and proprietary curcumagalactomannoside, which is an extremely bioavailable form of curcuminoids from the combination of curcumin from turmeric and galactomannans from isolated fenugreek seeds. CurQfen® is the product of a proprietary (patent pending) process of ultrasonic impregnation that infuses, saturates and binds galactomannan fibers with curcumonoid particles to create curcumagalactomannoside material that is very stable and bioavailable.

CurQfen®’s new technology shows a 25-fold increase in the concentration of curcuminoids in animal blood and 12-times the concentration in human blood after 24 hours.

CurQfen® delivers the active “free” curcuminoids into tissues and dramatically improves cell uptake (even through the blood-brain-barrier) compared to unformulated dietary curcuminoids and the best curcumin and piperine combinations or formulated conjugated curcuminoids.

IAM™ (Immune Assist Micron™)

IAM™ is an All–star medicinal mushroom group that is a technologically advanced immune modulation support ingredient.

Research shows IAM™ activates 260 different classes of immune cells, including the NK cells, T-cells, macrophages, and many others.

Each of the six mushroom species–Agaricus blazei Murill, Cordyceps, Shitake, Maitake, Reishi, and Turkey Tail–offers slightly different polysaccharide structures, which activate many more types of immune cells than just simple beta glucans.


Setria® Glutathione is an advanced, specialized form of glutathione that can be supplemented orally and clinically proven to increase cellular levels of glutathione. Glutathione is the most important intracellular antioxidant and toxin cleanser of the GI Tract and throughout the entire body.

Glutathione is recognized as the great protector and our first line of defense to eliminate ingested toxins before they can enter our body through our GI tracts.

Glutathione is also such a powerful antioxidant that without glutathione, each cell would become so ravaged by free radicals that it would disintegrate.

A lack of glutathione would also negatively affect the liver and immune system. By fighting free radicals, glutathione supports the liver so it can carry out its job of detoxifying the blood and the body.

Likewise, preventing toxin absorption and free radical damage in the gut also helps to promote a healthy immune system.

PepZin GI® (Zinc L-Carnosine Complex)

PepZin GI® provides relief of indigestion without suppressing stomach acid and possibly impacting digestive function. It also has been clinically demonstrated to relieve symptoms of indigestion, such as: heartburn, nausea, upset stomach, belching, bloating, inappetence, and diarrhea. It also delivers 20 mg of elemental zinc per serving.

Organic Sunflower Phospholipid Comprehensive Profile

Phospholipids–the backbone of most biological membranes–are essential in repairing and restoring the integrity of existing cell and mitochondrial membranes.  They are also critical support to the body when making new functioning cells and mitochondrial membranes to support the healing processes.

Organic sunflower phospholipids also contain special mitochondrial phospholipids allowing cells to produce more mitochondria per cell. Mitochondria are the cell's energy powerhouses that produce energy for the biochemical processes that must take place in our body to support life, and energetic wellness.

This profile provides an excellent source of organic sunflower phosphatides, which is non-GMO and allergen-free, and can help strengthen the GI/brain connection through repairing cell signaling, restoring cell receptor activity and production of neurotransmitters in the brain and nervous tissue.

The profile includes the following: 

  • Phosphatidyl-choline (PC)
  • Phosphatidyl-ethanolamine (PE)
  • Phosphatidyl-glycerol(PG)
  • Phosphatidyl-inositol (PI)
  • Phosphatidyl-serine (PS)
  • Phosphatidic acid (PA)
  • Digalactosyldiacylglyceride (DGDG)
  • Monoglactosyldiacylglyceride (MGDG)

Sensoril® (Ashwagandha)

This has been in the United States market for more than 12 years with studied efficacy and safety. It is a very effective adaptogen helping to reduce the effects of stress and improve our ability to manage it better.

Stress is a major contributor to poor health, including gut dysfunction. When the gut is dysfunctional, it affects our ENTIRE BODY including our immune function, blood sugar regulation and brain function, among other things!

Organic Amla Fruit is also known as Indian gooseberry, amalaka or amlaki.

A native to India, the amla fruit could be considered one of the most medicinal plants used in Ayurvedic medicine. It is very rich in Vitamin C (30% more than oranges), and contains many minerals, tannins, polyphenols, flavonoids as well as phytochemicals, calcium, phosphorus, iron, carotene and vitamin B complex.

Amla’s vitamin C can neutralize toxic free radicals in the body. As mentioned above, glutathione neutralizes free radicals too; but vitamin C and glutathione perform tasks that cannot be duplicated by the other. Vitamin C “spares” and helps recycle glutathione back to its active form in the tissues, and glutathione converts oxidized dehydroascorbate back into the active form of vitamin C in the tissues. Supplementing vitamin C can help raise levels of active glutathione in the body helping to meet the oxidative stress of our daily lives.

Amla provides powerful antioxidant protection and anti-inflammatory properties.


Quercetin is a potent anti-inflammatory, antioxidant and redox molecule with demonstrated ability in TER (Transepithelial Electrical Resistance) studies to enhance intestinal barrier (tight junction) function through assembly of zonnulin occludens (ZO2), occludin and claudin-13 similar to lignite extract.


Rutin is a bioflavonoid that can help maintain collagen production and reduce mucosal interleukin-1 beta (IL-1B) levels, as well as IL-1A, another cell signaling protein, known to cause auto-inflammatory syndromes. 

Organic Prune Fruit Powder

Organic prunes are rich in antioxidants, fiber, unique phytonutrients and other components with mild laxative effects.

Marshmallow Root

Marshmallow root has been shown to help soothe irritated mucous membranes due to inflammation.

Slippery Elm Bark

Slippery elm bark has been shown to help soothe irritated mucous membranes due to inflammation.

Cat's Claw

Cat's claw is a medicinal plant from the Amazon River basin and has been widely used for inflammatory disorders. Studies have shown cat's claw to suppress TNF-alpha production, a cell signaling protein involved in promoting systemic inflammation 

Qing Dai

Qing dai has a long history in traditional Chinese medicine to treat inflammation, primarily in the stomach and digestive tract, through its powerful antioxidant properties.


Selenium is essential for normal immune function and plays a critical role in gut health.

Polyphenol C®

Polyphenol-C® Whole Vitamin C and all its synergists (non-GMO) provides of  600mg of non-GMO vitamin-C and 100mg of berry polyphenols in each gram. 

Nature delivers vitamin-C to us in the colorful packages of fruits and berries. The deep purples, blues and reds of these fruits comprise their polyphenol components: anthocyanins, proanthocyanidins, bioflavonoids and others.

These compounds enhance the role of vitamin-C and are the most abundant source of antioxidants in our diets. Anthocyanins are the primary active forms found in fresh berries such as blueberries, blackberries, raspberries and strawberries. These compounds also play important roles as immune enhancers, anti-inflammatory activity, cardiovascular support and many other health functions.


BGF-Immune® is a clinically studied, immune support ingredient containing high purity 1,3-Beta-Glucan produced via a unique fermentation process. 1,3-Beta-Glucan supports healthy immune function by working on the cells of the innate immune defense system to mobilize a complex set of immune defense mechanisms.

What About Probiotics? That is a great question!

You may be wondering why probiotics (“good bacteria” supplements) are not included in Dr. Tennant’s® Microbiome Support, the formula focuses on a prebiotic approach instead.

Taking a prebiotic approach with advanced, stable, high-molecular weight, soluble fibers like Propol A® (see details above) and larch arbinogalactin, is proving to enhance the existing colonies of good bacteria and support the entire gut microbiome significantly better and with less chance for distress than with probiotics

The most recent research has shown that probiotics may provide little to no benefit in a dysbiotic, highly oxidative, inflamed gut. Probiotics may even aggravate GI symptoms. Caution should be exercised in people with potential auto-immune GI disease such as Crohn's. 

It is important to regain a more balanced GI environment before probiotic supplements would provide optimal benefit. 


Dr. Tennant’s® Microbiome Support helps detox, cleanse and heal the gut. Its clinically studied ingredients help improve intestinal wall integrity, reducing inflammation and supporting immune system modulation and regularity.
