The Importance of Gut Microorganisms

By Dr. Russell Blaylock, M.D.

What we have learned over the past several decades is that the microorganisms within the colon (which include bacteria, fungi, and certain viruses — called collectively microbiota), play a major role in virtually every aspect of physiology and ongoing development.

Other functions these organisms perform in the human body include:

  • Reducing inflammation
  • Inhibiting cancer
  • Maintaining immune health
  • Producing important nutrients
  • Playing a role in the manufacture of bile
  • Secreting a number of neurotransmitters
  • Playing a major role in stress adaptation
  • Playing a crucial role in brain health and development

Editor's Note: This Gut Health Secret Is Key to Your Body’s Immune Challenges

The human gut contains trillions of microorganisms, more than 100 times the number of genes as are found in our cells.

In fact, there are thousands of different bacterial species within the colon alone. Recent studies have shown that these microbiota are part of a complex network called the microbiota-gutbrain axis, which also involves the nerves in the walls of the gastrointestinal tract, the autonomic nervous system (sympathetic and parasympathetic systems), the neuroendocrine system (special hormones), and the immune system.

Basically, this axis amounts to a two-way communication link between the brain and the intestines.

The gut bacteria (microbiota) talk to the brain by special chemical messages, and the brain talks back to the gut via the vagus nerve and spinal nerves. There is compelling evidence that the development of the brain is dependent on a healthy assortment of gut microorganisms that colonize a baby’s intestines very soon after birth.

The main sources of these highly beneficial bacteria are in the mother’s birth canal during natural childbirth and by ingesting mother’s milk during breastfeeding.

Babies born by C-section and those that are bottle-fed have a different assortment of gut microbiota. This can affect their development and future health, especially behavioral health.

Another important factor during this early stage of development is exposure of the baby (and later the young child) to antibiotics, which can kill or severely alter these vital organisms.

It appears that after a person’s microbiota is established, the organisms remain fairly stable throughout life.

A New Health Alert for Older Adults From David Brownstein, M.D.

Supporting Your “Second Brain”
Offers New Hope for Better Immune Health,
Stable Mood, and Overall Well-Being

Dear Friend Over 50,

In family practice, I see many older adults on a daily basis.

And one thing is crystal clear.

As you grow older, your immune system just doesn’t work as well as it used to.

Scientists call it “immune senescence.” This process is actually considered a hallmark of the aging process itself.

Unfortunately, it leaves older folks increasingly susceptible to a variety of health concerns.

David Brownstein, M.D. believes holistic medicine will be THE medicine of the 21st century. He is a board-certified family physician and one of the foremost holistic practitioners in America. He teaches other physicians and the public about his success using natural treatments and nutritional therapies. He has had great success in resolving numerous medical disorders, including arthritis, thyroid disease, chronic fatigue, hormone imbalance, diabetes, and many others. Dr. Brownstein is the author of 14 health books, and editor of the popular monthly newsletter Natural Way to Health.

That’s why I’m writing today.

To tell you about a research-proven natural health strategy that offers seniors new hope . . .

With support for better immune function, a more stable mood, improved digestion, and overall well-being.

And it’s all connected to an area of your body you might not expect has anything to do with your immune system.

But before we get into this natural solution, it’s important to know how growing older contributes to immune function decline:

  • First, with increasing age, you have fewer immune T cells. These cells are necessary to recognize and respond to health threats.
  • Second, you accumulate more worn-out memory-type T cells, which have lost their ability to divide and function properly.

    Instead, they release pro-inflammatory molecules. An imbalanced inflammatory response further accelerates immune system decline — and contributes to many other health issues seniors face.

  • Third, older adults face a decrease in natural killer (NK) cell activity, linked to increased risk of adverse health concerns.

But apart from changes to specific cells in your immune system . . .

There’s a key factor associated with the immune decline of aging — and it relates to your gut.

The Immune System and Your “Second Brain”

Did you know you have two brains?

Deep within the walls of your gut lies a network of 100 million nerve cells — more than you have in either your spinal cord or peripheral nervous system.

Scientists call this second brain in your digestive system the enteric nervous system or ENS.

While it can’t balance your checkbook or help you solve a crossword puzzle, your gut’s second brain is extremely powerful.

And these powers extend far beyond merely processing the food you eat.

Here’s why . . .

Scientists have discovered that around 70% to 80% of your immune system is actually located inside your gut.

This immune system in your digestive tract is designed to “fence off” potential threats from gaining entrance to the rest of your body through your circulation.

And the enteric nervous system inside your gut helps to regulate many of your vital immune functions.

So as you can imagine, supporting your gut’s immune system is vital to maintaining health as you age.

Providing this support means taking care of the defenders that live there.

The “Soldiers” in Your Gut

Your gut is home to about 100 trillion bacteria. So many of them, they weigh 2 or 3 pounds!

And because so many living organisms make a home there, many scientists now consider your gut to be an organ of sorts. They call it the microbial organ — or microbiome.

You’ve probably heard about the beneficial bacteria in your gut — your defending “soldiers.”

For you to remain optimally healthy, about 85% of the bacteria in your gut should be comprised of friendly bacteria, such as Lactobacillus or Bifidobacteria.

The remaining 15% are different kinds of non-beneficial microbes, but their minority status helps keep them in check.

Unfortunately, in many people — especially older folks — this ratio becomes skewed. The non-beneficial bacteria increase in numbers, crowding out your good soldiers.

And since most of your immune system is located in your gut, this does not bode well for your aging immune function.

In fact, research shows that a delicate balance of microbial species is required to maintain healthy immune function. A disturbance in this balance can result in an imbalanced inflammatory response leading to health concerns, even the frailty of old age.

Threats to Your Gut Bacteria

Researchers are becoming more and more aware that microbial balance in the gut becomes increasingly disturbed by the aging process itself.

And not only that . . .

Consider how many toxins we’re exposed to today — especially in our water and food.

More than 80,000 chemicals are currently used in the U.S. today. Most of them have not been adequately tested for their effects on our health. Of course, this includes our gut health.

And there’s the matter of our generally poor diets, low in fiber and high in fat and refined carbohydrates. As a nutritionally-oriented doctor, I consider this a major factor.

These dietary concerns influence the type of gut microbes we have — as well as their ability to function. Because this can negatively modify immune function.

Even certain medications can disrupt the proper balance of your gut microbes. Of particularly importance are medications you know as antibiotics.

Antibiotics and Your Immune Health

According to the Centers for Disease Control and Prevention (the CDC), at least 30% of antibiotic treatments prescribed in the outpatient setting are unnecessary.

Unfortunately, every time a person takes antibiotics, sensitive bacteria are killed. But resistant ones are left to grow and multiply. This means that overuse of antibiotics is a major cause of the epidemic rise in drug-resistant bacteria.

And this antibiotic resistance is of particular concern for older adults, who have a high rate of antibiotic use.

Because antibiotics have a wide range of effects, they also kill off those “friendly” bacteria in the gut, leading to upset in the composition of the intestinal microbes.

Eventually this can lead back to that undesirable imbalanced inflammatory response and immune health concerns.

And if this wasn’t bad enough, what happens in your gut also affects your mood and your overall health.

Your “Second Brain” Influences
Mood and Well‑Being

Contrary to popular opinion, mood changes are not all in your head . . .

Whenever you’ve experienced a “gut feeling” or felt “butterflies in your stomach,” this is your second brain talking to you.

A big part of your emotions are likely influenced by the nerves in your gut, which communicate back and forth with the brain in your skull.

It may surprise you to know that your gut’s enteric nervous system is home to more than 30 neurotransmitters, including serotonin, norepinephrine, epinephrine, and dopamine.

In fact, 95% of your body’s serotonin is found in the bowels.

Serotonin is a chemical responsible for mood control (you’ll often find serotonin regulated by certain antidepressant medications).

Scientists are just beginning to unravel the complexities of the enteric nervous system. They’ve found that the bacteria in your gut may affect not only the gut, but the mind itself.

Emerging research indicates that your gut’s nervous system may influence emotions, response to stress, pain perception, and other aspects of behavior.

According to Johns Hopkins University, the enteric nervous system can trigger big emotional shifts in people coping with digestive health concerns such constipation, bloating, stomach upset, and others.

That’s because irritation in the GI system sends signals to the brain that can trigger these mood changes.

In fact, research suggests that serotonin dysfunction in the GI system can lead to impairments in brain function that involve mood, sleep, and behavior.

This is yet another important reason to keep your gut happy and healthy.

So what’s the best way to do this?

Well, I don’t really recommend commercial yogurts today.

They are loaded with sugar and other additives. Plus, they are often heat processed or pasteurized, which destroys some of their live bacterial cultures.

That’s why I recommend supplementing your diet with probiotics to help balance the bacteria in your gut.

This is especially important for older adults, as you’ve already seen.

Millions of people take probiotics today, but do they really work?

The answer is “yes” — with a caution you’ll see in a moment.

And the science is solid . . .

Multiple clinical trials have found that probiotics can enhance immune function in the elderly.

A 2019 review of research in the Annals of Nutrition and Metabolism also notes that probiotics help regulate the inflammatory process.

The Harvard Health website reports that probiotics can do more than support the health of your digestive tract. They can enhance mood and cognitive function — and decrease stress and anxious feelings.

And a 2017 review in the journal Gut Microbes considers the use of probiotics a sound nutritional strategy for healthy aging.

However . . .

Despite all these great benefits of probiotics, it’s not a smart idea to go down to your drugstore, grocery store, or discount store and pick up a bottle.

The Real Truth About Many Probiotic Supplements

Unfortunately, researchers warn that about half of the probiotic products available today do not contain the bacteria listed on the label.

Even those that do may not have the correct mix of bacterial strains to benefit your health.

And low quality products may not be manufactured in the correct way to help the bacteria survive a trip to the supermarket shelf, no less the harsh trip through your acid-laden GI tract.

For this reason, using a high quality probiotic supplement is the only way to guarantee maximum health benefits.

Consider Only a High Quality Probiotic Supplement

To be honest, I was very frustrated with the low quality, ineffective probiotic solutions I found on the market today.

And seeing the need for more abundant probiotic bacteria in the diets of my patients — especially my older patients . . .

I decided to take matters into my own hands and develop my own own advanced formula. A formula with the best mix of proven probiotic strains, based on my two decades of research and patient treatment.

It’s called BACTIPRO®.

Six Powerful Probiotic Strains in
One Chewable, Tasty Wafer

When it comes to probiotics, there’s no “one size fits all.”

So I used a mixture of six proven beneficial bacterial strains in BACTIPRO.

The variety of strains ensures powerful support for immune health, digestive health, and more.

You’ll find strains from both the Bifidobacteria family and the Lactobacillus family, and here’s why:

The two Bifidobacteria strains in BACTIPRO primarily work in the large intestine to help detoxify your colon and support normal elimination.

And the four included Lactobacillus strains in BACTIPRO primarily work in the small intestine to assist in digestion and absorption of foods, particularly in absorption of vitamins, minerals, and other nutrients your body requires.

And since few people get enough fiber in their diet today . . .

BACTIPRO also includes the breakthrough fiber product Fibersol-2.

With 6 full grams of healthful fiber per daily serving, this helps to support intestinal regularity.

Plus, it provides prebiotics that encourage the growth of even more friendly bacteria.

You can think of prebiotics as “food” to nourish the probiotic microbes.

Plus, in each tasty BACTIPRO wafer, you’ll find a powerful antioxidant blend of 8 fruit-based nutrients, including resveratrol and grape seed extract.

Antioxidants help protect and repair your body’s cells from damage caused by free radicals. It’s particularly important for older individuals to minimize the impact of these free radicals on your body by boosting your antioxidant intake.

BACTIPRO also contains a robust complex of phytonutrients from 26 different fruits and vegetables. These include carotenoids important in immune system health, and flavonoids that help optimize the body’s inflammatory response.

And unlike many cheap and inferior probiotics on the market, BACTIPRO is manufactured under stringent quality controls to ensure the potency and stability of the product and the bacterial strains.

I’m confident in the research behind the ingredients in BACTIPRO — and in the processing and packaging that goes into bringing it directly to you ready to provide you with a source of high-quality probiotic strains.

In fact, I’m so confident that BACTIPRO can help support both your immune and digestive systems, I want to tell you about a special offer I arranged for you.
