Probiotic Formula
Dr. Tennant's® Probiotic Formula is designed with:
-
Acid-resistant, time-release capsule technology with Capsugel® DRcaps®, which ensure probiotics are protected from stomach acid and arrive uncompromised in the GI tract.
-
Prebiotics – Highly-effective, clinically-proven prebiotics to help further ensure probiotic viability.
- 30 Billion Probiotic CFUs (colony forming units) in each capsule of well-known probiotic strains.
Dr. Tennant’s® Probiotic formula provides a biological synergy with “good bacteria” (probiotics), “food for the probiotics” (prebiotics) and a protective, delayed-release delivery technology to maximize probiotic effectiveness and support a healthier GI system.
Dr. Tennant’s® Probiotic Formula’s time-release, acid-resistant capsule technology protects the probiotics from early exposure to oxygen, moisture or stomach acid. This allows each capsule’s delivery system to target the gastrointestinal tract and deliver the highest quality ingredients directly where they need to be without compromise.

What is Dr. Tennant’s® Probiotic Formula?
Dr. Tennant’s® Probiotic Formula is a powerful synbiotic formula that combines both probiotics and prebiotics. It supports a healthier gastrointestinal (GI) system by providing a unique blend of probiotics and prebiotics that work together synergistically.
What is a synbiotic formula?
A synbiotic formula combines probiotics and prebiotics to create a biological synergy that supports a balanced and healthy microbiome in the GI system.
What are prebiotics?
Prebiotics are substances that provide nourishment to probiotics, supporting their growth and effectiveness. They help maintain a healthy microbiome by stimulating the growth of beneficial bacteria in the GI tract.
How does Dr. Tennants® Probiotic Formula ensure probiotic viability?
Dr. Tennant’s® Probiotic Formula utilizes advanced delivery technology, including Capsugel® DRcaps® (Delayed-Release Capsules), which protect probiotics from stomach acid and deliver them safely to the intestines for colonization.
Why are high CFUs not always necessary?
Research suggests that for daily maintenance of a healthy gut microbiome, most people need about 10-20 million CFUs (colony forming units). Higher CFUs don't necessarily translate to better results, as stomach acid can diminish their viability.
How do probiotics survive stomach acid?
Stomach acid can kill probiotics, which is why we use the advanced delivery system Capsugel® DRcaps®. These capsules protect probiotics from stomach acid and ensure they reach the intestinal tract.
What probiotic strains are included in the formula?
Dr. Tennant’s® Probiotic Formula includes eleven key probiotic strains, such as Lactobacillus Acidophilus, Bifidobacterium Bifidum, and Lactobacillus Plantarum, known to support a balanced microbiome.
What is Propol®A and why is it used in the formula?
Propol®A is a special prebiotic included in Dr. Tennant’s Probiotic Formula. It's a high-molecular-weight mannan fiber that acts as food for beneficial bacteria, contributing to a healthy microbiome.

Probiotics for Gut Health: A Smarter Way to Heal Your Gut from the Inside Out
You know that feeling when something’s just... off? Maybe it’s the bloating that sneaks in after a “healthy” meal, or the brain fog that lingers like a cloud you can’t quite shake. Maybe it’s your skin breaking out like you’re sixteen again, or the kind of fatigue that no amount of sleep or coffee seems to touch.
You’ve tried eating better. Maybe you’ve even dabbled in cleanses, green powders, or cutting sugar. And yet something still isn’t right. Your body keeps sending signals, subtle and not-so-subtle, that it’s operating out of sync.
Here’s the truth: it’s not just you. And you’re not imagining it. More often than not, what you’re feeling starts in your gut.
Your gut is the foundation of your entire well-being. It’s home to trillions of bacteria that affect everything from your digestion to your immune function, energy levels, and mood. When this microbial ecosystem falls out of balance, the effects ripple throughout your body in ways most of us don’t even realize.
And while probiotics may seem like the obvious answer (cue the crowded supplement aisle and confusing CFU counts), not all probiotics for gut health are created equal. Most never make it to where they need to go. That’s where Dr. Tennant’s® Probiotic Formula comes in: smart, targeted, and backed by science.
It’s time to listen to your gut and actually give it what it needs to thrive.
What Are Probiotics and Why Do They Matter?
Think of probiotics as the friendly, hard-working bacteria that keep your digestive system and your entire body in balance. They help break down food, absorb nutrients, regulate immune response, and even influence your mood and hormones. But modern life? It’s not exactly kind to these tiny allies.
Between antibiotics, stress, aging, and sugar-heavy diets, the beneficial bacteria in your gut can easily get overwhelmed. And when that happens, symptoms start showing up everywhere, not just your stomach.
- Bloating and irregular digestion
- Fatigue and brain fog
- Skin flare-ups
- Weakened immunity
Sound familiar? That’s your gut saying, “Help!”
Not All Probiotic Supplements Are Created Equal
If you’ve ever stood in the supplement aisle, confused by labels promising “50 billion CFUs,” you’re not alone. While the CFU (Colony Forming Units) number is important, higher doesn’t always mean better. Because here’s the kicker: most probiotic supplements don’t even make it to your intestines alive.
Your stomach is designed to break things down, and it does a great job destroying delicate bacteria on contact. If your probiotics aren’t protected, they’re toast.
That’s why Dr. Tennant’s® Probiotic Formula is different. It’s not about throwing more bacteria at the problem. It’s about delivering the right strains, in the right amount, with the right support.
Why Dr. Tennant’s® Probiotics Actually Work
Here’s what sets this formula apart:
1. Delayed-Release, Acid-Resistant Capsules
Did you know that most probiotics die in the stomach? Dr. Tennant’s® Probiotic Formula uses patented Capsugel® DRcaps®, delayed-release, acid-resistant capsules that safely deliver probiotics straight to your intestines, where they’re needed most.
2. Clinically-Studied, Balanced Strains
No random strains. No bloated CFU numbers. Just 11 carefully selected probiotic strains that work synergistically with your body. These strains, like Lactobacillus and Bifidobacterium, are naturally found in the human gut and are backed by research for digestive, immune, and cognitive health.
3. Built-in Prebiotics for Nourishment
Probiotics are only part of the equation. They need food to thrive, and that’s where prebiotics come in. Dr. Tennant’s formula includes a powerful, natural prebiotic trio: inulin, Jerusalem artichoke, and baobab fruit powder. These nourish good bacteria and help them colonize your gut, instead of just passing through.
Probiotics and Aging: Why Your Gut Needs Extra Support Now
Your microbiome isn’t static. It evolves and often declines as you age. The diversity of beneficial bacteria begins to drop, the gut lining weakens, and inflammation creeps in. That’s why older adults often experience more digestive issues, fatigue, constipation, and lowered immunity.
But the good news? Your gut is incredibly responsive to intentional care. With targeted probiotic supplements, the right prebiotics, and a consistent routine, you can help restore balance and vitality at any age.
Buy Probiotics That Deliver Real Results
Let’s recap:
You don’t just need probiotics. You need probiotics that are:
- Delivered safely past stomach acid
- Supported with prebiotics to help them grow
- Made with strains that are naturally compatible with your body
Dr. Tennant’s® Probiotic Formula checks every box. Whether you’re navigating the gut changes of midlife or just trying to feel more like yourself again, this supplement is designed to support real transformation.

I am finishing my existing bottle. I assume it’s necessary to keep it refrigerated. Is that the case? I did leave the bottle unrefrigerated for a week or more. Thanks for your reply. Steuart Chaney
