Social Anxiety and the Gut: What Your Microbiome Says About Your Social Fears

If you’ve ever felt your stomach churn before a social event or noticed digestive issues during stressful times, you’re not imagining the connection. New research shows that social anxiety and the gut have a surprisingly deep relationship – one that goes far beyond nervous butterflies.

Scientists now understand that social anxiety may leave an actual biological footprint in your gut microbiome. This groundbreaking discovery opens the door to understanding how caring for your gut might help support your emotional well-being during socially challenging moments.

The Gut-Brain Connection Nobody Talks About

Think of your gut and brain as constant texting buddies – they’re always communicating through what scientists call the gut-brain axis. This communication highway runs both ways, with your gut bacteria playing a surprisingly active role in the conversation.

Your digestive system contains trillions of bacteria that do more than just help digest food. These microscopic organisms produce molecules that influence everything from inflammation to stress responses, and how your brain processes social situations. When your gut microbiome shifts out of balance, it can affect how anxious you feel, especially in social settings.

What the Research Actually Shows

Recent studies reveal something remarkable: adolescents with social anxiety disorder have a distinct microbiome signature that differs from their peers without anxiety. Researchers found specific differences, including:

Higher levels of certain bacteria like Prevotella and Anaeromassillibacillus
Lower levels of beneficial bacteria like Parasutterella
Different metabolic activity in the gut

But here’s where it gets really interesting. When scientists transferred gut bacteria from teens with social anxiety into newborn rats, something unexpected happened. The rats who received the “anxious microbiome” started showing more social fear and wariness, particularly in unfamiliar situations. They became more cautious around other rats they didn’t know, mirroring the social hesitation seen in humans with social anxiety.

This wasn’t just one study either. Multiple research teams have now shown that social anxiety-associated gut bacteria can transfer anxiety-like behaviors between individuals, and even across species. The animals who received microbiota from people with social anxiety also showed changes in brain chemistry, including altered levels of oxytocin (the “bonding hormone”) and increased inflammation markers.

Why Adolescence Matters

Our teenage years represent a critical window for both brain development and microbiome establishment. The brain circuits that handle emotions and social behavior are still forming during adolescence, and your gut bacteria appear to influence this process.

When the gut microbiome shifts during this developmental period, it can affect metabolic signaling that ultimately shapes brain chemistry. This may help explain why social anxiety often first appears during the teen years and why some people seem more vulnerable to developing these fears than others.

What This Means for You (And What It Doesn’t)

Let’s be clear about what this research tells us—and what it doesn’t.

What the Science Shows:

Social anxiety creates measurable changes in gut bacteria composition
These microbiome differences can influence anxiety-like behaviors in animal studies
The gut-brain axis plays a real role in how we experience social situations
Supporting gut health may complement traditional anxiety treatments

What the Science Doesn’t Show:

That “bad bacteria” cause social anxiety by themselves
That you can catch social anxiety from someone else
That probiotics alone will cure social anxiety disorder
That everyone with gut issues has anxiety, or vice versa

Social anxiety remains a complex condition shaped by genetics, life experiences, personality, environment, and biology. Your gut microbiome appears to be one piece of this larger puzzle – an important piece, but still just one factor among many.

The Two-Way Street Between Stress and Your Gut

Here’s something important to understand: stress can change your gut microbiome. When you feel anxious, your body releases stress hormones that affect digestion, gut barrier function, and the balance of bacteria in your intestines. This creates a potential cycle where anxiety changes your gut, and those gut changes may reinforce anxious feelings.

Your gut bacteria communicate with your brain through several pathways:

The vagus nerve, which directly connects your gut to your brain
Immune system signaling, since most of your immune cells live in your digestive tract
Metabolites and neurotransmitter precursors produced by gut bacteria
Inflammatory molecules that can cross into your bloodstream

These pathways help explain why gut health and emotional well-being are so interconnected.

Practical Ways to Support Your Gut-Brain Axis

While we don’t yet have a “probiotic cure” for social anxiety, supporting your gut health makes sense as part of a broader wellness approach. Think of these strategies as tools that work alongside therapy, stress management, and other evidence-based treatments—not replacements for them.

Build a Microbiome-Friendly Plate

Your daily food choices create the environment where your gut bacteria live. Focus on variety and whole foods rather than restriction:

Load up on fiber-rich plant foods like vegetables, fruits, legumes, nuts, seeds, and whole grains. These feed beneficial bacteria and help them produce helpful metabolites.
Cut back on ultra-processed foods that are high in added sugars, refined carbohydrates, and artificial ingredients. These can promote inflammation and unfavorable bacterial shifts.
Embrace healthy fats from sources like olive oil, avocados, and fatty fish, which support both gut health and brain function.

Add Fermented and Prebiotic Foods Naturally

You don’t need expensive supplements to start supporting your gut bacteria:

Fermented foods like yogurt with live cultures, kefir, sauerkraut, kimchi, and kombucha introduce beneficial microbes and bioactive compounds
Natural prebiotics found in onions, garlic, leeks, asparagus, bananas, and oats feed the helpful bacteria already in your gut
Mix and match these foods throughout your week rather than eating the same things daily

Consider Quality Probiotic Support

Research on probiotics for anxiety shows mixed but encouraging results. Studies find that probiotic supplements may help reduce anxiety symptoms, especially when combined with other healthy lifestyle choices.

The key word here is “may” – not all probiotics work the same way, and scientists haven’t yet identified the perfect bacterial strains for social anxiety specifically. What we do know is that multi-strain formulations like EndoMune Advanced Probiotic offer a comprehensive approach by including various beneficial bacteria types.

If you’re considering probiotics for a child or teenager, choose age-appropriate formulations like EndoMune Kids Advanced Chewable Probiotic that are specifically designed for younger digestive systems.

Important note: Probiotics and prebiotics should complement – not replace – professional treatment for social anxiety disorder. Always discuss major supplement changes with a healthcare provider, especially if you’re taking medication or have other health conditions.

Support Your Whole System

Your gut doesn’t exist in isolation. These lifestyle factors all influence both gut health and anxiety levels:

Move your body regularly: exercise increases beneficial gut bacteria diversity and directly reduces anxiety symptoms through multiple pathways
Prioritize quality sleep: poor sleep disrupts gut bacteria and makes anxiety worse, while good sleep supports both
Practice stress management: techniques like deep breathing, mindfulness, or yoga can reduce the stress hormones that negatively affect your gut
Stay socially connected: even small, comfortable social interactions support mental health (and interestingly, social connection may also influence gut bacteria composition)

What Comes Next in Gut-Anxiety Research

The science of social anxiety and the gut is still evolving rapidly. Researchers are working to identify:

Which specific bacterial strains and metabolites are most important for social fear regulation
Whether there are critical windows during childhood and adolescence when gut-focused interventions might be most effective
How dietary changes, probiotics, or other microbiome-targeted treatments might enhance traditional therapy outcomes
Whether microbiome testing could eventually help identify people at higher risk for developing social anxiety

For now, the most practical takeaway is this: caring for your gut health represents a meaningful way to support your overall emotional resilience. This becomes especially valuable during socially demanding life phases like adolescence and young adulthood.

The Bottom Line

Social anxiety and the gut share a deeper connection than most people realize. Recent research reveals that social anxiety leaves a measurable biological footprint in the gut microbiome, and these bacterial communities can influence anxiety-like behaviors through the gut-brain axis.

While we can’t yet say that probiotics “treat” social anxiety disorder, supporting your gut health through diet, lifestyle, and targeted supplements offers a science-backed way to complement traditional anxiety treatments. Think of gut health as one important pillar in a comprehensive approach that also includes therapy, stress management, social support, and healthy daily habits.

The emerging science of the gut-brain connection reminds us that mental and physical health aren’t separate, they’re deeply intertwined. By nurturing the trillions of bacteria living in your digestive system, you’re also supporting the emotional resilience that helps you show up confidently in social situations.

Key Takeaways

Social anxiety creates distinct changes in gut bacteria composition, particularly noticeable during adolescence
Research shows that transferring gut microbes from socially anxious individuals to animals can trigger anxiety-like behaviors
The gut-brain axis connects your microbiome to brain circuits that regulate social fear and emotional responses
Supporting gut health through diet, fermented foods, prebiotics, and quality probiotics may help reduce anxiety symptoms
Gut microbiome support works best as part of comprehensive anxiety care that includes therapy and lifestyle management

The Gut-Brain Connection: How Probiotics Support Mental and Cognitive Health

Digestive Health, Healthy Aging, Mental Health / By Staff Writer

How Probiotics Support Mental and Cognitive Health

When most people hear “probiotics,” they think about digestive health. But did you know your gut does much more than help you digest pizza or salad? Scientists now know that your gut and brain are in constant communication, and the right probiotics can make a big difference for your mood and ability to think clearly—no matter your age.

The Gut-Brain Axis: Your Body’s Secret Communication Superhighway

Your gut and brain are connected by a network called the gut-brain axis. Think of it like a super-fast messaging app between your stomach and mind. The “texts” they send travel through:

Nerves: The vagus nerve runs from your gut up to your brain, passing along important signals from your gut/digestive symptoms to your brain.
Chemicals: Your gut also uses neurotransmitters, like serotonin and dopamine, the brain’s happy messengers, to talk directly to your brain.
Immune Signals: Gut bacteria help control inflammation, which can protect your brain by ensuring the pathways described above maintain their peak performance.

When your gut bacteria, also called your “microbiome,” are healthy, it boosts both your brain and mood. When your microbiome is out of balance, it affects how well you process stress, remember things, or handle anxiety. Clearly, if you’re under stress or suffering from anxiety, it’s important to keep your gut-brain axis as healthy as possible.

How Probiotics Influence Your Mind and Mood

Probiotics are the “good microbes” that live in your gut and come from either probiotic supplements or gut-friendly foods like yogurt and fermented foods like kombucha. Research shows that probiotic bacteria help your mental health by:

Calming Stress: Probiotics can lower stress hormone levels (like cortisol) and send relaxing signals to your brain.
Boosting Mood: By helping your gut make more serotonin, probiotics are shown to help reduce symptoms of depression and anxiety.
Improve Focus and Memory: Recent clinical studies, especially those using multi-strain probiotics, found improved reaction time, sharper thinking, and better executive function by enhancing your brain’s command center for decision-making.

Neuroimaging research (think: brain scans) has shown that taking probiotic supplements doesn’t just help your gut; they actually change how your brain works!

In fact, studies show that people who take probiotics regularly have:

Stronger Connections In Regions of the Brain Linked to Maintaining Focus
Reduced Activity In Areas That Lead to Negative Thoughts Or Feeling Distracted
A Boost In Regions of The Brain That Handle Emotion And Stress

What Does the Latest Science Say?

Recent experiments and meta-analyzes have found that regular probiotic use can:

Decrease Anxiety And Depression Scores on Mental Health Tests
Reduced Physical Stress Responses – Like a Racing Heart When Nervous
Help With Emotional Balance and Sharper Thinking, Even Under Pressure

One review from 2024 used brain scans to show that probiotics increase brain connectivity in networks that help you stay calm and collected, especially when you’re feeling overwhelmed. This means probiotics really help your brain handle stress better.

Myth Busting

There is a lot of misinformation out there about gut health, gut diseases, and probiotics. Especially probiotic supplements. Don’t fall for these common misconceptions:

“Probiotics are Only for Digestion.” This is False! Probiotics Have Direct Impacts on Your Mood And Cognitive Function via the Gut-Brain Axis.
“All Probiotics Are The Same.” Not True. Multi-Strain Probiotics (Using Different Bacteria) Offer The Biggest Mental Benefits According to Recent Peer-Reviewed Studies.
“You’ll Feel Changes Overnight.” This is Another Misconception. Perceptual Mind and Mood Benefits Typically Emerge/Appear After A Few Weeks Of Regular Use.

The Key is regular use. If you take intermittent doses of probiotics, either through eating a healthy diet without processed food or through probiotic supplementation, your results will be reduced.

Simple Definitions

Gut Microbiome: The Collection of Good and Bad Bacteria Living Inside Your Digestive System.
Probiotics: Good Bacteria, Often Found In Healthy Foods, or in Probiotic Supplements, That Help Your Gut and Brain Function Better.
Neurotransmitters: Chemicals Like Serotonin and Dopamine That Pass Signals Between Your Gut and Brain.
Executive Function: Your Brain’s Ability to Plan, Focus, Remember, and Make Decisions.
Serotonin: A Chemical In Your Body Associated With Calmness, Focus, and Well-Being. It Also Plays a Significant Role in Digestive Functions, Appetite, and Sleep.
Dopamine: A Chemical In Your Body Linked to the Brain’s Reward System, Motivation, Pleasure, and Motor Control.

Everyday Tips for a Healthier Gut-Brain Connection

Here’s how to boost your gut-brain health today:

Eat More Fiber-Rich Foods – Veggies, Fruits, and Whole Grains are Your Gut’s Favorite Food and Diets Rich with Fiber Reduce the Need For Probiotic Supplements.
Try a Quality Multi-Strain Probiotic. Products like EndoMune Advanced Probiotics are Formulated Specifically to Support Both Gut and Mental Wellness.
Limit Sugary Drinks and Processed Snacks, Which Feed Bad Bacteria and Hurt Gut Health.
Manage Stress Through Activities You Enjoy – Music, Sports, or Quality Time with Friends Help Your Mind Reduce Stress and Anxiety.
Get Plenty of Sleep. Your Gut And Brain Both Need Rest to Perform at Peak Efficiency.

Key Takeaway: Take Charge of Your Brain—From the Inside Out

With new scientific research showing how important the gut-brain axis is to your mental health and mood, repairing or enhancing your gut health could be the key to thinking faster, feeling better, and staying resilient in tough times – without drugs or other medication. A simple daily addition like a multi-strain probiotic could help unlock both a healthier gut and a happier mind.

The Gut-Brain Axis: How Probiotics Support Mental Health Through Digestive Wellness

Digestive Health, Mental Health, Probiotics / By Staff Writer

Have you ever experienced “butterflies” in your stomach before a big event? Or made an important decision based on a “gut feeling?” These familiar feelings hint at something scientists recently confirmed: your gut and brain are deeply interconnected through what we call the gut-brain axis.

The Gut-Brain Axis isn’t just responsible for digestive issues during times of stress – it may also play a crucial role in your mental well-being. Recent scientific research reveals that our gut biomes influence our mood, anxiety, and cognitive function. That makes sense. No one is happy or at their emotional and cognitive best when their gut is upset.

What Exactly Is the Gut-Brain Axis?

The gut-brain axis is a bidirectional network linking your central nervous system (brain and spinal cord) with your enteric nervous system (the intricate network of neurons lining your gastrointestinal tract).

This network has multiple pathways, including the vagus nerve, hormonal signals, immune system activity, and other neurotransmitters.

One of the most important discoveries about this connection is that approximately 90 percent of your body’s serotonin—a neurotransmitter that regulates mood—is produced in the gut, with specific bacteria playing important roles in its production.

This finding revolutionizes how we understand the relationship between digestive and mental health.

How Your Gut Microbiome Affects Your Brain

The balance of your gut biome appears to impact your brain function through several mechanisms:

Neurotransmitter Production: Gut bacteria produce neurotransmitters like serotonin, GABA, and dopamine that regulate mood, anxiety, and cognitive function.
Inflammation Control: Healthy guts reduce oxidative stress by producing antioxidant enzymes and inhibiting inflammatory responses, which improves neurological function.
Stress Regulation: A healthy microbiome helps regulate the body’s stress response by influencing the hypothalamic-pituitary-adrenal (HPA) axis, which controls cortisol (the body’s primary stress hormone) release.
Immune System Modulation: The gut microbiome plays a vital role in regulating your immune system, which affects inflammation levels throughout the body, including the brain.

When Your Gut Microbiome Is Out of Balance

An imbalance in gut bacteria (dysbiosis) can inhibit this vital gut-brain communication. Recent research has linked dysbiosis to various mental health challenges, including:

Anxiety Disorders
Depression
Stress Sensitivity
Cognitive Impairment
Sleep Disturbances

Scientists from Duke-NUS Medical School recently discovered that specific microbial metabolites—particularly indoles—directly regulate brain activity linked to anxiety, opening exciting possibilities for probiotic-based therapies to improve mental health.

The Probiotic Solution: Restoring Balance for Better Mental Health

Probiotics—beneficial gut microorganisms—offer a promising approach to supporting both gut and mental health. These “good bacteria” can help restore balance to your gut microbiome and strengthen the gut-brain axis.

According to a review published in February 2025, probiotics can regulate gut microbiota, which is vital not only for digestion and metabolism but also for immune function and mental health.

Multiple clinical studies show probiotics’ potential mental health benefits:

Reduced Anxiety and Depression Symptoms: A 2025 randomized, double-blind, placebo-controlled study found that a multi-species probiotic reduced negative mood in healthy volunteers, with effects beginning after just two weeks of daily use.
Improved Stress Resilience: One study found that workers taking a probiotic containing Lactobacillus plantarum experienced significant reductions in self-perceived stress, depression, and overall negative emotions, along with decreased cortisol levels.
Enhanced Cognitive Function: Research has shown that specific probiotics like Lactobacillus rhamnosus are associated with improved cognitive performance, including better mental alertness and focus.
Reduced Rumination: Patients given a multi-strain probiotic experienced significantly fewer ruminative thoughts (repetitive negative thinking) compared to those taking a placebo.

EndoMune Probiotics: Supporting Your Gut-Brain Connection

EndoMune Advanced Probiotic, developed by a board-certified gastroenterologist, promotes digestive health and supports overall wellness, including the vital gut-brain connection.

What makes EndoMune particularly effective for supporting the gut-brain axis?

Multi-Strain Formulation: EndoMune Advanced Probiotic contains 10 strains of beneficial bacteria from the Lactobacillus and Bifidobacterium families, including Lactobacillus rhamnosus referenced above.
Prebiotic Support: EndoMune includes fructo-oligosaccharides (FOS), a natural prebiotic made from plant sugars that feeds beneficial bacteria and enhances their effectiveness. Prebiotics like FOS may help mitigate depressive symptoms and support brain health alongside probiotics.
Scientifically Formulated: The specific bacterial strains in EndoMune were selected based on scientific research into their benefits for both digestive and mental well-being.
Lactobacillus and Bifidobacterium Focus: These generally have shown significant potential in modulating the microbiota-gut-brain axis.

How EndoMune Supports Serotonin Production

Serotonin is often referred to as a “happy hormone” due to its influence on mood and emotional regulation. Scientists estimate that 80-90 percent of the body’s serotonin is produced in the gut. Research published in the medical journal Cell linked the production of serotonin in the gut by enterochromaffin (EC) cells to specific bacteria.

In an experiment with mice, researchers found that EC cells from germ-free animals produced about 60 percent less serotonin compared to normal mice. When gut bacteria from normal mice were transplanted into germ-free mice, their serotonin levels rebounded.

EndoMune’s multi-strain formula helps support the diverse bacterial community necessary for optimal serotonin production, potentially supporting more stable mood regulation naturally.

Beyond Serotonin: Multiple Pathways to Mental Wellbeing

The benefits of probiotics for mental health extend beyond serotonin production. As noted by researchers at University College Cork in Ireland, probiotics (sometimes called “psychobiotics” when referring to their mental health benefits) can produce and deliver neuroactive substances such as gamma-amino butyric acid (GABA) and serotonin, which act on the brain-gut axis.

EndoMune’s comprehensive formula supports multiple pathways that influence mental well-being:

Anti-Inflammatory Effects: Reducing inflammation that can contribute to mood disorders.
Improved Intestinal Barrier Function: Preventing leaky gut that can trigger systemic inflammation.
Enhanced Nutrient Absorption: Supporting optimal brain function through improved nutrition.
Balanced Immune Response: Preventing overactive immune reactions that affect the brain.

How to Incorporate EndoMune into Your Mental Wellness Routine

For optimal gut-brain axis support:

Consistent Daily Use: Take EndoMune Advanced Probiotic daily as directed to maintain a steady presence of beneficial bacteria.
Pair With Prebiotic Foods: Enhance the effectiveness of your probiotic by consuming prebiotic-rich foods like bananas, onions, garlic, asparagus, and whole grains.
Reduce Stress: Even the best probiotics work better when complemented by stress-management practices like meditation, adequate sleep, and regular exercise.
Limit Gut Disruptors: Minimize eating processed foods, excessive alcohol, and unnecessary antibiotics that can disrupt your gut microbiome.
Be Patient: While some people notice improvements in digestion quickly, the mental health benefits of probiotics often develop gradually over several weeks of consistent use.

The Future of Gut-Brain Health Research

The field of gut-brain axis research is expanding rapidly. Scientists are investigating how specific probiotic strains might address various psychological conditions by modulating the hypothalamic-pituitary-adrenal (HPA) axis, directly influencing the immune system, and through the production of neurotransmitters and neurohormones.

Research consistently shows that incorporating prebiotics, probiotics, and symbiotics (combinations of pre- and probiotics) into a healthy diet can lead to improvements in cognitive functions and mood, potentially offering fresh approaches for maintaining brain health as we age.

Key Takeaways: A Holistic Approach to Mental Wellness

The emerging science of the gut-brain axis offers an exciting perspective on mental health, one that acknowledges the profound connection between our digestive system and our emotional well-being. By supporting your gut microbiome with a high-quality, multi-strain probiotic like EndoMune Advanced Probiotic, you’re not just investing in better digestion, you’re potentially supporting your mental health from the inside out.

Remember that probiotics work best as part of a comprehensive approach to wellness that includes a nutritious diet, regular physical activity, stress management, and good sleep hygiene. By addressing both your gut and brain health simultaneously, you may discover a more balanced, resilient state of well-being – naturally without medication.

PTSD, Your Diet and Your Gut

Diet, Digestive Health, Mental Health / By Staff Writer

Summary: The diet you follow and how your gut manages it may determine how you’ll experience post-traumatic stress disorder (PTSD).

It’s hard to imagine a connection between post-traumatic stress disorder (PTSD) and the human gut until you recognize how the gut-brain axis links your brain, gut and emotions.

Unfortunately, many of us only notice our gut-brain axis when those connections are disrupted by many factors, including poor diets that often lead to an array of gut-related health problems that drive inflammation.

The good news: Following a gut-healthy Mediterranean diet can do a lot of good to ease or even prevent PTSD-related symptoms, based on findings featured recently in Nature Mental Health.

Healthy eating for mental health

Researchers at Harvard T.H. Chan School of Public Health and Brigham and Women’s Hospital in Boston teamed up on the report that collected data on 191 women from the Nurses’ Health Study.

These women were assigned to three categories: Probable PTSD, trauma exposure but no PTSD and a control group with no trauma exposure. Patients were evaluated on everything from BMI, diet, age, mental health and PTSD symptoms to multiple stool samples.

When researchers compared the diets women consumed to the number of PTSD symptoms they experienced, that’s where the differences in mental health became very apparent.

Women who consumed standard Western diets high in red and processed meats experienced more PTSD challenges while others who followed healthier Mediterranean diets faced fewer symptoms.

What’s more, scientists identified a specific species of gut bacteria — Eubacterium eligens — whose abundance was positively associated with patients who experienced fewer PTSD problems and ate diets rich in the fruits, healthy fats, vegetables and fish that make up the standard Mediterranean diet.

The major takeaway from this study: If you are experiencing mental health challenges, working on your gut-brain axis connection by eating healthier meals with higher amounts of dietary fiber, incorporating more exercise in your daily routine and getting more sleep matters.

When you’re working long days and you don’t have the time to follow your healthier routines, give your gut some extra protection by taking a probiotic, ideally with multiple strains of beneficial bacteria and a prebiotic that feeds the good bugs in your gut, like EndoMune Advanced Probiotic.

Women: Are You Protecting Your Gut-Brain Axis?

Digestive Health, Mental Health, Women’s Health / By Staff Writer

Women: Are You Protecting Your Gut-Brain Axis?

A healthy and balanced gut microbiome keeps a woman’s gut-brain axis working smoothly and makes a world of difference to her emotional health. Women: are you protecting your gut-brain axis?

Not so long ago, science debated the existence of the gut-brain axis, the connection that links your gut, emotions and brain.

That changed once modern medicine proved that as much as 90 percent of the serotonin (a chemical that governs your emotions) your body produces comes from your gut and specific bacteria play key roles in making it.

Your ability to generate the amount of serotonin your body that keeps your gut-brain axis working as it should and your emotions on an even keel depends on the healthy diversity of bacteria in your gut.

This balance or imbalance of gut bacteria concerning emotional health was the chief finding in a recent study appearing in Psychological Medicine.

The Study

In the first phase of research, scientists from Brigham and Women’s Hospital and Harvard surveyed more than 200 middle-aged women about their feeling over the past 30 days, asking them to report positive and negative emotions along with how well they handled them.

Three months later, women provided stool samples that were analyzed in ways that enabled researchers to find patterns in human health and how their emotions influenced them.

No surprise, women who suppressed their emotions had less diverse gut microbiomes and higher levels of bad bacteria while those who reported happier feelings had lower levels of those specific species.

“This was what you would expect, but it was kind of amazing that we saw it,” says Dr. Laura Kubzansky, a professor in the Chan School’s department of behavioral science at Harvard.

The Solution

There’s a lot a woman can do to give her gut-brain axis a gentle reset in a good direction, starting with making lifestyle changes. For example, eating healthier meals including foods rich in dietary fiber is a great start.

When life gets in the way and you’re on the go, here’s an additional step you should consider: Take a probiotic formulated with multiple strains of lab-tested beneficial bacteria and a prebiotic that feeds the good bacteria in your gut.

If you’re looking for a probiotic that will protect the healthy balance of bacteria in your gut and strengthens the connections in your gut-brain axis, consider the proprietary blend of 10 strains from the Lactobacillus and Bifidobacterium families plus a proven probiotic (FOS) in each daily dose of EndoMune Advanced Probiotic.

Probiotics + An Antidepressant = Gut-Brain Axis Relief

Mental Health / By Staff Writer

Probiotics + An Antidepressant = Gut-Brain Axis Relief

Are you taking an antidepressant to help you better manage your emotions, but finding that drug you’ve been prescribed isn’t working as well as it should?

That’s not unusual at all given that some 60 percent of patients with a major depressive disorder (MDD) experience some issues with first-line medicines, and about a third of patients continue to have problems after more treatments.

This may be a sign that your gut brain axis — the proven connection that links your brain, intestines and emotions — may need some extra help, especially if you’ve been diagnosed with an MDD.

Scientists at King’s College London came to a similar gut-based conclusion after conducting a pilot study that monitored the mental and physical health of MDD patients appearing in JAMA Psychiatry.

Multi-Strain Probiotics To The Rescue

A small group of 46 adult patients (primarily women ages 18-55) completed a trial that compared taking an antidepressant (mainly an SSRI drug) with a multi-strain probiotic or a placebo every day for eight weeks.

Interestingly, both probiotic and placebo groups experienced improvements in their symptoms, but the probiotic enjoyed even better results from week four to the end of the trial.

“The gut-brain axis is a truly fascinating and rapidly evolving area of microbiome research,” says study author Dr. Viktoiya Nikolova. “The findings of this pilot study are an important step forward in our understanding of the role of probiotics in mood and mental health.”

This isn’t the first time we’ve shared how effective multi-strain probiotics can be in relieving symptoms of depression, but it’s among the first to use them alongside antidepressants.

Interestingly, all but one of the strains of beneficial bacteria contained in EndoMune Advanced Probiotic were ingredients contained in the probiotic used in this study.

So, if you’re struggling with a MMD and are concerned it’s not working as it should, consider giving your gut-brain axis a gentle boost with the help of EndoMune.

Sleep Challenges, Sarcopenia and Your Gut

We never get tired of reminding you how much a good night’s sleep can do for your health as a natural way to reboot your body, a lot like your home computer, to repair and restore itself after the stresses of the day.

Staying up too late, following a work schedule that includes 24/7 shift duty or traveling across multiple time zones not only disrupts your body’s natural circadian clock, but it takes away valuable time your body needs to replenish itself.

Over time, these sleep deficits can harm you significantly, leaving you more vulnerable to the cluster of health problems better known as metabolic syndrome.

As you know, the gut plays a major role in your sleep too, and even short-term, drastic changes can harm the balance of gut bacteria you need to maintain good health.

Sleep problems and gut disruptions may also play a key role in worsening sarcopenia, the age-related and progressive loss of strength and muscle mass that often contributes to functional declines especially among seniors, according to a study appearing in the journal Sleep.

Analyzing The Data

A group of European researchers based these conclusions about the links between sarcopenia, gut imbalances and poor sleep based on an analysis of 11 clinical studies conducted with health patients ranging in age from 4-71.

In many ways, sleep problems and gut health issues go hand-in-hand in creating an environment in which sarcopenia emerges as one more serious health challenge.

At the gut level, sleep problems influence an unhealthy balance of gut bacteria that also reduces the structural integrity and functionality of the wall of the gut (which could lead to leaky gut problems).

Bad sleep may also be a trigger for imbalances in gut bacteria that can also create the production of pro-inflammatory chemicals. Even one sleepless night creates an environment that favors anabolic resistance and muscle breakdown.

Muscle Growth and Your Gut

We know this initial review of studies is a toe in the water when it comes to understanding the collision of gut bacteria imbalances, poor sleep and sarcopenia, yet there’s no denying the link between muscles and good gut health is a real one.

Interestingly, another recent review of studies published in the Journal of Cachexia, Sarcopenia and Muscle found a very gut-healthy way to improve muscle mass and muscle strength with the help of probiotics.

In fact, researchers noted significant improvements in global muscle strength among adults older than age 50 after taking a probiotic for at least 12 weeks. Also, among the strains of beneficial bacteria cited in this report included several featured in EndoMune Advanced Probiotic.

There’s still a lot we don’t know about the connections between muscle growth and the gut, but we do know how a healthy gut and a good night’s sleep work hand-in-hand to give your overall health a major boost.

IBS and Your Gut-Brain Axis in Conflict

IBS and Your Gut-Brain Axis in Conflict

A good argument can be made for irritable bowel syndrome (IBS) being not only the most common condition gastroenterologists diagnose — it affects an estimated 15 percent of all Americans — but one of the most challenging ones too.

But familiarity doesn’t guarantee clarity, considering IBS comes in three different subtypes: IBS-D (diarrhea), IBS-C (constipation) and IBS-A (a mix of diarrhea and constipation).

An aspect of IBS that’s rarely explored: its potential impact on your gut-brain axis, the connection that links your brain, intestines and emotions.

So, it should come as no surprise that mental health issues are much more prevalent among IBS patients than those who aren’t, based on an analysis of data conducted by researchers from the University of Missouri.

Mental Health Challenges and IBS

Scientists collected mental health data on more than 1.2 million IBS patients hospitalized in 4,000 U.S. hospitals over a three-year period from a national database, according to the study appearing in the Irish Journal of Medical Science.

More than 800,000 IBS patients in a hospital setting experienced symptoms of anxiety (38 percent overall) or depression (27 percent overall) at rates more than double the norm compared to people without IBS.

Overall, the prevalence of those problems plus bipolar disorder, suicidal attempts/ideation and eating disorders was significantly higher than the general adult population.

This is where the gut-brain axis comes into play, says Dr. Zahid Ijaz Tarar, lead researcher and assistant professor of clinical medicine at the University of Missouri. “Medical professionals need to treat both ends of the axis.”

“I frequently tell my patients who have IBS that, if they have any type of psychologic stress, it will get expressed in some form or another,” says Yezaz Ghouri, senior author and assistant professor of clinical medicine and gastroenterology at the University of Missouri.

Given that at least 90 percent serotonin your body produces is generated in the gut and specific bacteria play key roles in producing it, disruptions from IBS or other gut health issues do matter.

Solutions For Treating IBS and Gut-Brain Axis

If you suffer from IBS and have emotional challenges because your gut-brain axis is out of balance, plenty of good options are available that help out on both fronts.

For example, cleaning up your diet, devoting some time each week to exercise and paying attention to your sleep can do a lot of good.

If managing your stress becomes a challenge, your physician may want to prescribe an antidepressant drug like a selective serotonin reuptake inhibitor (SSRI) like fluvoxamine or an older tricyclic drug like amitriptyline.

You’ll also want to consider taking a probiotic, a proven and effective non-drug solution that helps your gut and brain at the same time. But not just any probiotic will do…

A probiotic formulated with proven strains from the Bifidobacterium and Lactobacillus families, like those contained in EndoMune Advanced Probiotic, can go a long way toward relieving your IBS and rebalancing your gut-brain axis safely and effectively.

How Poor Sleep Affects Your Gut

How Poor Sleep Affects Your Gut

It’s hard to imagine people who are more sleep-deprived and really need their rest the most than those who serve in our military.

Sleep schedules often turn around on a dime from around-the-clock duty cycles to long periods of rest and relaxation, depending on the day and the mission at hand.

Even for those of us who aren’t active duty service men or women or first responders, big shifts to sleep schedules (like shift work) create problems for our circadian clocks that help us regulate many parts of our lives, including our body temperature, the way we digest food and the health of our gut.

Even short-term but drastic changes to sleep patterns can alter the composition of bacteria in the gut, according to a recent study appearing in Scientific Reports.

No Sleep

Nineteen healthy service members between ages 17-45 who had previously followed normal sleep schedules and hadn’t taken antibiotics for three months or probiotics and other supplements for two weeks participated in the trial.

Soldiers were randomly selected for three-day periods of healthy sleep (7-9 hours) or unhealthy sleep (two hours per night) separated by up to a 21-day break (depending on which rest interval came first). Diets were monitored as were periods of exercise and stool samples were taken after each service member woke up for the final day of each three-day sleep period.

It wasn’t surprising that restricted sleep reduced the diversity of bacteria in the gut, but it was the actual amount — an estimated 21 percent over just three days — that grabbed the attention of researchers.

Imagine the harm done to the human gut over much longer periods, especially for first responders in pressure situations that last for weeks on end.

Follow Our Sleep Protocol

Fortunately, there’s lot you can do to ease any challenges with sleep and we address some of the basics in our Sleep 101 feature where we recommend an easy-to-follow protocol (which doesn’t include melatonin).

One additional step you can take that will make a big difference in your sleep: Make sure your diet is rich in prebiotics, foods that contain non-digestible plant fibers and carbohydrates that feed the bacteria in your gut.

If you’re not getting enough prebiotic-rich foods (apples, oats, garlic and onions), skip the melatonin, follow our sleep protocol and be sure to take a prebiotic-rich, multi-strain probiotic like EndoMune Advanced Probiotic.

Enhance Mental Health With Multi-Strain Probiotics, Antidepressants

Modern medicine has really warmed up over the years to acknowledging the existence of the gut-brain axis, the vital connection that links your brain, emotions and intestines.

This relationship has become so familiar and accepted, modern medicine has begun to explore how probiotics may become an important tool in support of standard treatments for major depressive disorder (MDD), better known as depression.

That’s important, considering two-thirds of all patients don’t respond well initially to antidepressants, and nearly 30 percent of treatment-resistant patients experience additional symptoms when receiving specialized treatments.

Scientists at the University of Basel cited those downbeat numbers when sharing the very positive results of their study appearing in Translational Psychiatry that showed how multi-strain probiotics can make a real impact of the mental health of patients grappling with depression.

The Gut-Brain Axis Difference

Forty-seven patients completed the trial that compared mental health scores based on taking a multi-strain probiotic or a placebo in addition to their usual treatments for 31 days.

(Four of the eight strains of bacteria in the multi-strain probiotic used in this study are contained in EndoMune Advanced Probiotic, including ones from the Lactobacillus and Bifidobacterium families.)

Although symptoms of depression decreased among all patients, researchers observed a greater 55 percent improvement among those taking a multi-strain probiotic, not only in mental health scores but maintaining an abundance of good gut bacteria.

What’s more, the beneficial effect of taking a probiotic was observed in a reduction of neural activity in the portion of the brain that influences some motor behaviors and modes of learning known as the putamen.

One caveat to these good positive findings that most would expect: Levels of those health-promoting bacteria dropped four weeks after the end of the study, making scientists wonder if roughly a month was time enough to stabilize a patient’s gut and their gut-brain axis.

Taking a probiotic is a great non-drug solution for treating persistent health problems ranging from depression to irritable bowel syndrome.

The way to get the most out of any probiotic, like EndoMune, is to take it every day, and if you need some tips on taking one, check out our recently updated how-to basics for all age groups and the four good reasons why probiotics make such an important impact on your health.
