Dr. Tennant's 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:

  • Selected key probiotic strains known to safely support optimum human health
  • Highly effective, clinically-proven prebiotics to help further ensure probiotic viability. The selected prebiotics help to develop the hundreds of "good-bacteria" strains already present in the GI tract to help maintain a healthy microbiome balance.
  • A specialized delivery technology to help ensure transport of Dr. Tennant's specially selected probiotic strains through stomach acid and viability once in the GI tract.


Delivery Technology

Did you know that probiotics in most supplements do not survive stomach acid, or that exposure to any moisture “wakes up” probiotics and brings them out of their state of suspended animation? Exposure to moisture can occur while they are in a bottle on a shelf or after the bottle has been opened. In a few short days, they are no longer viable.

Dr. Tennant’s Probiotic Formula utilizes specialized delivery technology designed to keep probiotics alive and deliver them unharmed through stomach acid into the intestines, where they can colonize and provide health and wellness support.

Capsugel® DRcaps™ is a special vegetarian capsule technology that is proven to protect capsule contents through harmful stomach acid. Stomach acid can’t touch the selected probiotic strains in Dr. Tennant’s Probiotic.

The delayed release mechanism of Plus Capsugel® DRcaps™ further ensures that the probiotics get to where they need to go.

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.



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 11 of the most helpful probiotic strains that support human 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.

Many leading experts strongly support the supplementation of prebiotics as perhaps even 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. In fact, in one clinical study there was more than a 10% increase in beneficial Bifido bacteria strains in just 30 days!

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.

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.

As soluble fiber slowly moves through your GI tract, it ferments, creating gases and other byproducts 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.

What Are Prebiotics And Probiotics And How Are They Beneficial?

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. 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.


Probiotics: The Good Bacteria
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 keep 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.

“Bad bacteria,” too, 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, where gut flora work in several ways:
  • 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.

Probiotics: The Gut And Brain Connection
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 like anxiety and depression.


Here are just a few studies illustrating the connection probiotics have between the gut and brain:

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

    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 like mazes.

    Vagus Nerve: The Brain And 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 study 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.

    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.

    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 less instances of depression, anger, hostility, and excessive worry.

    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.
