Microbiome Support


Dr. Tennant’s® Microbiome Support, with its researched and clinically proven ingredients, helps get and keep your gut barrier healthy by supporting 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.
  • Helps to provide relief with more normalized bowel habits, as well as detoxification support in binding, shuttling, and eliminating toxins through the colon.

Let's look at some of them...

Lignite Extract - (Mother Earth Labs' Standardized 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 naturally.

There isn’t a more powerful immune supplement than Colostrum. IMMULOX® is a step above standard Colostrum.

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 it 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 the 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 patients 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


CurQfem® 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 utilized.

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™–Immune Assist Micron™, an all–star medicinal mushroom group, is a technologically advanced immune modulation support ingredient.
Research shows Immune Assist Micron™ 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—offer 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 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® (Zinc L-Carnosine Complex) 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.
An excellent source of Organic, Sunflower, Non-GMO, Allergen-Free Phosphatides that 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.
    • 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 twelve 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, just to name a few!

Organic Amla Fruit - Indian Gooseberry, Amalaka or Amlaki

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 studies (Transepithelial Electrical Resistance) 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 and fiber and 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, a medicinal plant from the Amazon River basin, 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). Each gram of Polyphenol-C® contains 600mg of Non-GMO Vitamin C and 100mg of Berry Polyphenols.

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.


That is a great question!

You may be wondering why Probiotics (“Good Bacteria” supplements) are not included in Dr. Tennant’s® Microbiome Support.

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 patients with potential auto-immune GI disease such as Crohn's. Prebiotics on the other hand can be incredibly beneficial.

It is important to regain a more balanced GI environment to allow probiotic supplements to truly work and provide benefit. Additionally, most supplemented probiotics do not survive through the stomach acid, with the exception of Dr. Tennant’s® Probiotic Formula.
