Probiotic Formula


Probiotic Formula

Dr. Tennant’s® Probiotic Formula is a powerful synbiotic formula.

Yes, you read that correctly – synbiotic (not symbiotic) formula. A synbiotic formula is a formula that combines probiotics and prebiotics. Because they work so much better together—a form of synergy—the term synbiotic is used to describe this biological synergy that can help support a healthier GI system. As you would expect, Dr. Tennant’s® Probiotic Formula takes synbiotic complementary medicine to the next level.

Dr. Tennant’s® Probiotic Formula includes:

  • Our Probiotic Formula provides ELEVEN key strains that are known to safely support a balanced and healthy microbiome and optimum human health.
  • Specialized advanced delivery technology to help ensure transport of Dr. Tennant's eleven specially selected probiotic strains through stomach acid so they maintain their viability once in the GI tract AND shelf stable so you are guarenteed viability of probiotics.
  • Our Probioitc Formula provides THREE highly effective, clinically proven prebiotics to help further ensure probiotic viability. The selected prebiotics help develop the hundreds of "good-bacteria" strains already present in the GI tract to help maintain a healthy microbiome balance.

Dr. Tennant's® Probiotics has 11 strains of probiotics


    2 Challenges with Probiotic Supplements  

    When Dr. Tennant developed his probiotic formula, he had two challenges he needed to deal with.


    Challenge 1 - How Do We Get The Probiotics Past Stomach Acid?


    You can see it everywhere, bottles touting 1 billion to 300 billion CFUs (colony forming units), and given the high numbers, it seems to reason that more is better, right?


    Absolutely not. Unless you have been diagnosed with a specific health issue and are working with a healthcare professional to treat it, studies have shown that most people need about 10-20 million CFUs for daily maintenance of a healthy gut microbiome.


    Now it is tempting to go out and get a probiotic that sits in that recommended range, but there is something you need to understand. 


    Stomach acid kills probiotics. 


    So you may consume 10 or 20 billion, but unless they are protected, when they finally get through your stomach acid, you may only have a few billion. This is why, in the supplement industry, the amount of CFUs has been steadily increasing. We now see 60, 100, and 300+ CFUs. But how much of what you are consuming actually reaches your intestines? In addition, if you already have a sensitive system or are struggling with digestive issues, there is a good chance this may exasperate an issue.


    If you are taking a probiotic, you need to be sure that enough probiotics survive and reach your intestines so they can grow.


    Challenge 2 - Exposure to Heat, Moisture, and Oxygen Kills Probiotics 


    These three things: heat, moisture, and oxygen, can destroy the probiotics you take and this makes handling and storage a real challenge when it comes to making sure any supplemental probiotic is viable when reaches the consumer. 


    If you are taking "live" probiotics, you need to keep them refrigerated. The minute probiotics are exposed to oxygen or any moisture, they “wake up” and begin deteriorating.  


    In addition, exposure to heat can kill "live" probiotics. Even though you purchase your probiotics from a refrigeration unit in the store, you have no idea how they were stored along their journey to you. Exposure to heat, oxygen & moisture can occur while they are in the bottle or on a shelf, and after you have opened the bottle, they begin to deteriorate in your refrigerator, and in a few short days, they are no longer viable.


    So if your probiotics supplement has been exposed to heat, humidity (moisture) or oxygen along their way to you or they are open, and in your refrigerator for too long, they can activate within the pill, only to die (due to lack of nutrients and proper environment).


    Dr. Tennant's probiotics are self stable and are small batch production



    These were two of the challenges Dr. Tennant faced when developing his Probiotic Formula. He wanted not only to make sure his patients were getting a good variety of high-quality probiotics, he also needed them to make it through the stomach acid and to ensure that no matter what they were exposed to, his patience were getting viable probiotics. 


    Solution 1 - Advance Time Delayed Delivery System

    To help your microbiome, we need to make sure the eleven good probiotics strains you are consuming make it to where you need them most, in your intestines.


    Dr. Tennant's® Probiotic Formula utilizes DRcaps®* (Delayed Release Capsules), a specialized delivery technology designed to keep probiotics safe from stomach acid and deliver them unharmed into the intestines, where they can colonize and provide gut health and overall health and wellness support.

    Dr. Tennant's Probiotics has a special capsule that allows it to make it through stomach acid


    *@Capsugel® DRcaps™ is a special vegetarian capsule technology that is not only time delayed but is also clinically proven to protect capsule contents through harmful stomach acid.


    In a qualitative and quantitative study using scintigraphic imaging methods, it was possible to assess the gastrointestinal transit of the Capsugel® DRcaps™ capsules and their release based on the scintigraphic images.


    This delayed-release mechanism of Capsugel® DRcaps™ further ensures that the probiotics get to where they need to go!


    Solution 2 - Shelf Stability - Ensuring Probiotics Are Not Destroyed 

    We know how our probiotics are handled during the manufacturing process and in our warehouse, but once they are shipped and on their way to you, it is impossible to control things such as temperature or other environmental concerns.


    In addition, many of Dr. Tennant's patients are busy professionals who travel, and keeping probiotics refrigerated was difficult.

    So to manage this, Dr. Tennant's probiotics are flash-frozen and then quickly freeze-dried, so they can handle many different environments without being compromised, and vitality is ensured. 



    Dr. Tennant’s® Probiotic Formula is formulated to provide 30 billion CFUs (colony forming units) per serving of extremely robust, highly-resilient microflora probiotic strains with the viability to replenish healthy GI microflora.

    The formula features ELEVEN of the most helpful probiotic strains that support your microbiome health:

  • Lactobacillus acidophilus
  • Bifidobacterium bifidum
  • Bifidobacterium lactis
  • Bifidobacterium longum
  • Lactobacillus bulgaricus
  • Lactobacillus rhamnosus
  • Bifidobacterium animalis lactis
  • Lactobacillus salivarius
  • Lactobacillus casei
  • Bifidobacterium breve
  • Lactobacillus plantarum


    Prebiotics support probiotics and make a significant contribution to the viability of healthy probiotic strains. Prebiotics are basically food for probiotics. Taking prebiotics helps probiotics work more efficiently and stimulates the growth of existing beneficial bacteria in the GI tract.

    Prebiotics in Dr. Tennant's probiotic formula

    Many leading experts strongly support the supplementation of prebiotics as perhaps being more important than supplementing probiotics, because prebiotics provide support to the hundreds of healthy strains already in the GI tract. Supplementing probiotics allows for the introduction of only a small number of strains compared to the hundreds of strains already present in the GI tract that need nourishment to ensure our overall health and wellness.

    Dr. Tennant’s® Probiotic Formula includes a special prebiotic called Propol®A. Propol®A is the highest molecular weight mannan fiber available today. Fibers (specifically plant fibers) are one of the primary foods of “good bacteria.”

    Propol®A's health benefits have been widely studied, and it has proven to be a superior prebiotic.

    A clinical study shows a 10% increase in beneficial Bifido bacteria strains in just 30 days!

    There has been a lot of attention surrounding the use and benefits of taking probiotics and how important they are for our health and well-being. Just like us, these beneficial bacteria need the right food to grow and thrive. This is where prebiotics come in. Think of them as food for intestinal fauna.

    Propol®A has over 60 international clinical studies and 14 safety studies that include claims beyond prebiotic support, such as healthy glucose, lower triglyceride levels and cholesterol management. Not to mention weight loss, and satiety studies, too.

    As soluble fiber slowly moves through your GI tract, it ferments, creating gases and other by-products that act as food for friendly internal organisms. This increased food supply supports improved colonization of these beneficial organisms allowing them to successfully perform all their jobs: transporting nutrients through intestinal linings and fighting off the bad bacteria that comes in with our food.


    Benefits of pre & probiotic


    Bacteria are single-celled microorganisms found everywhere on Earth—in water, soil, plants, and most parts of your body. In fact, bacteria outnumber the other cells in your body by about 10-to-1, and in some recent research, scientist are estimating this to be even higher.

    So if your body is comprised of 1 trillion cells, then there are 10 trillion bacteria in your body. Isn’t that amazing? Your skin and digestive system alone host about 2,000 different kinds of bacteria.

    The idea that bacteria are not all bad—that good bacteria, called probiotics, live in your body and help you maintain health and fight diseases—is an idea that’s just now becoming mainstream in the United States. You can get probiotics along with prebiotics (the fiber that good bacteria eat) from certain foods and from more inclusive probiotic supplements.

    Recent advances in medicine helped to clarify that the relationship between bacteria and humans is mutualistic; that is, both your body and the bacteria in it, benefit from each other. This line of investigation actually started early in the 20th century when Russian scientist Élie Metchnikoff hypothesized that some bacteria may promote health, rather than harm.

    He concluded that fermented milk helped to “seed” the intestine with friendly bacteria, which suppressed the growth of harmful bacteria. He suggested that it’s possible to modify the gut flora by replacing harmful bacteria with useful microorganisms. He would go on to win a Nobel Prize for his work.

    The World Health Organization (WHO) defines probiotics as “live microorganisms, which, when administered in adequate amounts, confer a health benefit on the host.” In other words, probiotics are bacteria that your body needs. Our digestive systems are full of bacteria—good and bad. The “good bacteria” do many things besides keeping our digestive system healthy and efficient. Probiotics help us in many ways, such as supporting our immune systems and synthesizing nutrients like B and K vitamins.

    However, “bad bacteria,” are also are present and can proliferate, especially when not enough “good bacteria” are present to keep them in check. Dysbiosis is the term that describes this unbalanced state.

    Probiotics add “good bacteria” back into your system, which can help restore balance to your body

    Did You Know?

    Between 70% and 90% of your immune system is located in your GI tract, This is where gut flora works in several ways:
    • By producing enzymes and proteins that can kill or inhibit harmful bacteria that cause illness or disease.
    • Crowding out the “bad” bacteria by giving them no space to grab onto.
    • Stimulating the secretion of Immunoglobulin A, an antibody that fights infection.
    Probiotics occur in fermented foods such as yogurts with active cultures. Keep in mind that often we can’t get enough probiotics through foods alone, and a supplement that provides active probiotics with prebiotics can help.

    There is a great deal of evidence that probiotics can do more than just regulate your digestive system. There are findings showing a connection between the bacteria in the digestive system and brain development, as well as a link to mental health issues such as anxiety and depression.

    Below are just a few studies illustrating the connection probiotics have between the gut and brain.

    Sage College in Troy

    Researchers at The Sage Colleges in Troy, New York, found that mice fed a harmless strain of soil bacteria learned a new maze twice as fast as mice who weren’t given the bacteria, and the bacteria-fed mice exhibited fewer signs of anxiety (such as over-grooming and searching).

    Karolinska Institutet in Sweden/Genome Institute of Singapore

      A study conducted by scientists at Karolinska Institutet in Sweden along with the Genome Institute of Singapore indicated that gut bacteria may play a critical role in brain development, and thus influencing behavior in adulthood.

        The researchers compared behavior between mice raised with normal gut bacteria and mice raised with no gut bacteria. The mice with no gut bacteria were more active and exhibited riskier behaviors than the normal mice. When the mice with no gut bacteria were exposed to normal bacteria early in life, their behavior as adults was more similar to that of normal adult mice.

        Exposing the mice with no gut bacteria to normal bacteria as adults had no effect on their behavior, indicating that bacteria play an important role in early brain development. In fact, the researchers identified significant differences in gene expression and signaling pathways between the two groups of mice; these differences involved learning, memory, and motor control.

        Researchers are also investigating the relationship between bacteria in the digestive system and psychological issues such as depression, stress, and anxiety. Medical researchers have long known that stress depresses immune function, but only recently have they linked stress to changes in gut bacteria. Researchers at Ohio State University and Texas Tech University discovered that exposure to stress changes the composition, diversity, and raw numbers of bacteria in the gut.

        This early research indicates that stress or psychological pressure has a significant impact on gut bacteria populations, which in turn affects immune function. This connection may explain why certain diseases, such as inflammatory bowel disease and asthma, often seem to get worse during periods of unusual stress. Brain cells have receptors that receive and respond to chemical signals from other cells.

        Brain&gut impacts

        One of these chemicals, a neurotransmitter called gamma-aminobutyric acid (GABA), inhibits activity in the central nervous system and regulates several physiological and psychological processes in the brain. In individuals who suffer from depression, certain GABA receptor components are decreased. When you suffer from stress or anxiety, certain GABA receptor components are increased.

        Research in Ireland

        To understand how gut bacteria impact brain chemistry, researchers in Ireland fed mice a broth containing a strain of Lactobacillus Rhamnosus that lives naturally in our digestive tract. The researchers then compared the mice’s behavior and brain chemistry to those of mice that were fed plain broth. In the bacteria-fed mice, the GABA receptor components associated with depression were higher, while the receptor components associated with stress and anxiety were lower.

        These results indicate that the bacteria helps maintain normal brain chemistry. In addition, the bacteria-fed mice exhibited much less behavior associated with stress, anxiety, and depression, and levels of stress hormones were significantly lower when the bacteria-fed mice were exposed to stressful situations such as mazes.

        Canadian Research

        Canadian researchers have demonstrated a link between gut bacteria and behavior in mice. By colonizing the digestive tracts of bacteria-free mice with bacteria from mice with different genetic behavioral patterns, they could determine whether the bacteria influenced the mice’s behavior. The mice with no gut bacteria in this experiment typically exhibit passive behavior. The mice with bacteria typically exhibit more active behaviors.

        The results of the experiments showed that the different bacteria compositions changed the mice’s predicted behavior patterns. Mice with passive genetic backgrounds became more active and daring when given the bacteria from active mice, while mice with active backgrounds became more passive when given bacteria from passive mice.

        French Study

        A French study looked at probiotics and their effects on psychological states in humans. In a 30-day trial, 55 healthy men and women were randomly assigned to take either a daily probiotic supplement consisting of two probiotic strains or a placebo.

        Participants filled out questionnaires before and after treatment to assess their mood, stress levels, and coping skills. Researchers also measured stress hormone levels in participants’ urine. Compared with the placebo group, the probiotic group had lower levels of urinary stress hormones, and study participants reported fewer instances of depression, anger, hostility, and excessive worry.

        In Summary: Vagus Nerve & The Brain & Gut Connection

        Figuring out how the brain and gut bacteria communicate is an important task. The vagus nerve connects the brain with the digestive system, and the researchers in the above studies confirmed that the Lactobacillus strain used this same pathway to exchange information with the brain. When researchers cut the vagus nerve in the bacteria-fed mice, the bacteria’s impact was lost; neither the mice’s behavior nor GABA receptor levels changed.

        All of this research indicates that disturbance to the gut bacteria—whether from illness, antibiotics, or other factors—can have a significant impact on behavior and one’s well-being.
