Ever wonder why you get butterflies in your stomach? Or why an impending decision can cause an attack of intestinal cramps? We all “feel it in our gut” when we know something to be true.
Like Siamese twins, the two brains are interconnected. When one gets upset, the other does too.
The gut has a powerful influence on all things brain-related.[i]
So if you are dealing with depression, and not responding to conventional treatment. Anti-depressants like Prozac and Zoloft are not working to alleviate your depression.
You are also likely dealing with abdominal pain, constipation, diarrhea, and bloating. Maybe even Irritable Bowel Syndrome or Celiac Disease. These are all gut-related problems.
Are you starting to see the gut-brain connection? When you address gastrointestinal issues, you’ll often find that depression, anxiety and brain fog are gone too.[ii]
Gut health affects your brain’s function moment-by-moment. And not only the brain. It also governs your overall health, long-term risk for disease, and longevity.

Meet Your Microbiome
Right now, your body is colonized by a multitude of organisms. They outnumber your human cells by a factor of about ten. If you isolated them all, they would fill a half gallon container.
This microbiome of naturally occurring flora occupies your entire body. With the largest concentration in your gut. Even the expression of your genes in individual cells is influenced to some degree by this microflora.
Many doctors are aware of the importance of the microbiome. And do understand the idea of gut microflora. But it’s amazing the number of doctors who have not made the gut-brain connection.
To be fair, 90% of the research on the human microbiome seen in peer-reviewed journals has only been published in the last 5 years.
In modern medicine much of this is brand new information. And you’re getting it here at Nootropics Expert long before the mainstream will see it.
So even though this topic is still in the early stages and what I’d call “frontier science”, I’ll share what we know so far. So you can learn how to:
- heal brain disorders
- put an end to moodiness, anxiety and depression
- boost your immune system and reduce autoimmunity
- improve metabolic disorders like diabetes and obesity
Gut Dysfunction Contributing to Brain Dysfunction
A decade ago, research at Kyushu University in Japan restrained germ-free mice in a tube for an hour. Then they did the same experiment with normal mice.
They measured the stress hormone output of both. And found the germ-free mice showed a much higher level of stress than the normal mice. The mice with no microbiome had a dysfunctional stress response.
This is where it gets interesting. They pretreated the germ-free mice with a bacterium called Bifidobacterium infantis. Then they repeated the same experiment. This time the once germ-free mice showed a similar stress response to normal mice.
The Japanese research team were pioneers. They were the first to show that intestinal microbes could influence stress in the brain. And hinted at the possibility of using a probiotic to help brain function.[iii]
Another research team at McMaster University in Canada again used germ-free mice. They colonized the intestines of germ-free mice with bacteria taken from another mouse. The recipient mice took on the personality of the donor mouse.
Are you starting to see a pattern here?
If the germ-free mouse was once timid, it would become more daring. Or more daring mice would become apprehensive and shy. Showing that microbe interaction with the brain could induce anxiety and mood disorders.[iv]
So if you are dealing with anxiety or depression, this may be your experience too. You could have chronic inflammation, or a depressed immune system.
carefully targeted, strain specific probiotics
is a great way to treat depression.
So how would gut-friendly microbes treat depression?
Your second brain is called the enteric nervous system (ENS). The sheaths of tissue lining your esophagus, stomach, small intestine and colon.
To put this in perspective, your gut contains 100 million nerve cells. Lining your gastrointestinal tract from your esophagus to your rectum.
Everything that ends up in your gut can have an effect. Somewhere in your body. An ongoing battle between good microbes and bad microbes determine who wins. And how you feel.
Research at the University of Cork in Ireland showed a compromised microbiome in mice mimicked human anxiety, depression and even autism.
Studies showed normal behavior could be restored. By treating test subjects with certain strains of benign bacteria.
Most of the experiments have been with mice. But lead researcher John Cryan believes the findings could lead to what he called “psychobiotics” for humans.
Probiotics for the Mind
Cryan defines a psychobiotic as: “a live organism that, when ingested in adequate amounts, produces a health benefit in patients suffering from psychiatric illness.”[v]
John Cryan and his partner Thomas Dinan back up our own experience. For using probiotics in mental health. Bacterial strains like bifidobacterium and lactobacillus affect behavioral changes in animal studies.[vi]
Large-scale placebo-controlled trials in humans are underway. We expect to see markers for anxiety, chronic fatigue, depression greatly reduced. Even anxiety associated with irritable bowel syndrome.
Alzheimer’s disease, Autism, immune disorders, chronic inflammation and Type 2 Diabetes. They’ve all been linked to a dysfunctional microbiome in the gut.
6 Keys to Boosting Your Brain
by Boosting Your Gut
How long does it take to correct a dysfunctional microbiome? Experience shows a significant change in the array of gut bacteria can take place in as little as six days. After starting a new dietary protocol including using the right psychobiotics.
But everyone is different. Your success will depend on the current state of your gut. And how quickly you can fully commit to making changes.
Here are 6 keys to supporting a healthy microbiome. Based on personal experience and the latest science.
What we know about psychobiotics is still in its infancy. So this is what you can do now. And we’ll have more in future issues of Nootropics Expert Breaking News.
Fermented foods provide probiotic bacteria. This method of preserving food is ancient. The Chinese were fermenting cabbage 6,000 years ago.You have many options to choose from including; yogurt (avoid yogurt loaded with sugar, artificial sweeteners and flavors), kefir, Kombucha tea, Tempeh, Kimchi, and sauerkraut. Pickles, pickled fruits and vegetables, and cultured condiments. Even fermented meat, fish and eggs.
Go Low Carb, High-Quality Fat
We are virtually identical to every human that has walked this planet. And for the better part of our history, our ancestors’ diets consisted of wild animals and seasonal fruits and vegetables.Today most people are centered on grains and carbs. Most of which contain gut-blasting, microbiome-damaging gluten. Carbs spike your blood sugar. Which upsets the balance of your gut bacteria. And almost instantly affects your brain.
Take this 2005 report from Boston University on 2,000 healthy people. It showed that those with the highest cholesterol levels performed better on cognitive tests than those with lower levels of cholesterol.[vii]
They contain nature’s best medicine for supporting the health of gut bacteria. They are all plant-based. And plants produce flavonoids to protect themselves from free radicals. These polyphenols are powerful antioxidants. And those benefits are passed on to you.In multiple studies, adding polyphenols to the diet has been shown to significantly reduce oxidative stress. Which in turn reduces the risk for neurological disease. Wine, coffee and chocolate in moderation. And all the tea you want.
Choose Foods Rich in Prebiotics
Prebiotics are fuel for your gut bacteria. And you get them from certain foods. Foods high in prebiotics have been part of our diet since prehistoric times.Prebiotics occur naturally in a variety of foods including: Acacia gum, asparagus, dandelion greens, chicory, Jerusalem artichoke, jicama, garlic, leeks, and onions (raw & cooked). You get the most benefit by eating all the others raw.
Avoid chemicals like chlorine found in tap water. Chlorine is great at killing bacteria. Including all the good bacteria in your gut. When taking probiotics make sure you take them with spring or filtered water for full effect. You don’t want to kill them on the way down.
Psychobiotics: Five Core Species
The number of probiotics available today can be overwhelming. The industry didn’t even exist a couple of decades ago.There are thousands of species of bacteria that make up the human microbiome. But we’ll focus on some major species that have been aggressively studied in both animals and humans.
I’ve simplified our recommendations to five core species that are widely available: Lactobacillus plantarum, Lactobacillus acidophilus, Lactobacillus brevis, Bifidobacterium lactis, and Bifidobacterium longum.
- Lactobacillus plantarum is found in kimchi, sauerkraut, and other cultured vegetables. It reduces gut permeability (leaky gut) which affects nearly every brain disorder. Including ADHD, depression and other brain-development disorders. plantarum is essential for fighting infection, controlling inflammation and bad bacteria.
- Lactobacillus acidophilus is in fermented dairy products including yogurt. It keeps good vs. bad bacteria in check. It curbs yeast infections, helps maintain healthy cholesterol levels, and combats pathogenic microbes. It also makes lactase which is needed to digest milk. And manufactures vitamin K1. Your body needs K1 to make vitamin K2. Without K2, your body can’t clear away calcium deposits. As this plaque accumulates, you have a greatly increased risk of heart disease.
- Lactobacillus brevis is found in sauerkraut and pickles. It boosts your immune system including enhancing killer T cell activity. brevis prevents the effects of certain gut pathogens. And increases levels of the brain growth hormone BDNF.
- Bifidobacterium lactis (also called animalis) comes in fermented milk products like yogurt. It boosts immunity, aids in digestive comfort, and knocks out food-born pathogens like salmonella (which causes diarrhea).
- Bifidobacterium longum is just one of 32 species that belong to the genus bifidobacterium. This is one of the first bugs to colonize at birth. It improves lactose tolerance, prevents diarrhea, food allergies, and the proliferation of pathogens. longum is also known to have antioxidant capabilities, scavenges for free radicals, and enhances brain growth BDNF production. And some studies have shown B. Longum can help reduce cancer by suppressing cancerous growths of the colon.
Choose a probiotic with at least the 5 strains I listed above. A good CFU (Colony Forming Units) target to shoot for is at least 30 billion CFU per capsule.
And don’t skimp on price. Most top probiotics are refrigerated because these are living organism. And if you are buying online, they should be shipped to you in a cold pack.
Try a Probiotic Enema
This won’t be for everyone, but you’d be amazed at how many people have benefited from this at-home procedure. It’s the best way to introduce probiotic bacteria directly into the bowel.
Enemas date back to the ancient Egyptians and Mayans. And are used to flush out the lower bowel by injecting fluid into the rectum.
All you need is an enema bag, 3-6 probiotic capsules (including bifidobacteria), and filtered (chlorine-free) water. Fill the enema bag with lukewarm filtered water. And open and dissolve the probiotic capsules in the water-filled enema bag.
Insert the nozzle tip into your rectum. Holding the bag higher than the nozzle, release the clamp so the water flows into the colon. Try to hold the enema for 30 minutes if possible.
How often this procedure is recommended depends of the needs of the patient. In someone who has had aggressive antibiotic therapy, for example, you could do probiotic enemas as often as three times weekly for 4 – 6 weeks. And then reassess the situation.
