What Is the Microbiome
and
Why Does It Matter
Your gut microbiome is a community of trillions of bacteria, fungi and other microbes living in your intestines. It plays a critical role in almost every aspect of your health.
Your Gut Is More Than Digestion - It’s Your Inner Ecosystem
Trillions of bacteria in your gut control vital functions.
Modern science shows
Your gut health influences your entire body
from digestion to mental clarity to hormone function
A Healthy Microbiome Helps

Gut Benefits
Strengthen your immune system
70% of immune cells live in your gut. A balanced microbiome
helps regulate your body’s defense system.
Stronger Immunity – Reduced illness &
inflammation
Support mood and brain function
Your gut produces up to 90% of your serotonin—a key mood-regulating neurotransmitter. Gut-brain axis regulates cognition and stress response
Sharper Mind – Enhanced clarity, focus & mental balance
Improve digestion & nutrient absorption
Your gut microbiome helps break down complex foods, synthesize essential vitamins (like B12 and K), and regulate bowel movements. It also affects fat storage, insulin sensitivity, and blood pressure.
Better Digestion – More energy, less bloating & stable metabolism
Maintain healthy weight and metabolism
Specific bacteria help control fat storage, blood sugar, and appetite hormones.
Metabolic Balance – Fat regulation, hunger cues, and energy levels
Clearer skin
Reduced inflammation means lower risk of acne, eczema, and other skin conditions.
Glowing Skin – Less acne, eczema, and dryness
Improve cardiovascular health
A healthy gut microbiome helps regulate cholesterol levels, blood pressure, and blood sugar, all of which are key to heart health. Certain gut bacteria also reduce inflammation, a major factor in heart disease.
Better Heart Health – Blood sugar, blood pressure & cholesterol support
Improve sleep quality
The gut microbiome influences the production of sleep-related hormones like serotonin and melatonin. A balanced gut supports a healthy sleep-wake cycle and helps reduce nighttime restlessness.
Improved Sleep – Deeper rest & better recovery
Support muscle function & recovery
The gut-muscle axis links your microbiome to muscle growth, strength, and repair. Healthy gut bacteria aid in protein digestion, nutrient absorption (like amino acids & magnesium), and inflammation control, all essential for muscle performance and recovery.
Stronger Muscles – Better performance & faster recovery
When Balance Breaks - Signs of an Unhealthy Gut
An imbalanced gut microbiome can disrupt nearly every system in your body—from digestion and immunity to mood and metabolism. Recognizing these warning signs is the first step toward restoring optimal health.
Digestive distress & metabolic imbalance
Bloating, constipation, diarrhea or alternating patterns—often tied to IBS, SIBO, or disrupted gut motility.
Unhealthy gut flora may influence weight gain, insulin resistance, increased cravings, and blood sugar instability.
Cognitive & energy issues
Imbalances may reduce neurotransmitter production and increase inflammation, leading to brain fog, low mood, and chronic fatigue.
Weakened immunity
Poor microbial diversity can impair immune response, increasing susceptibility to infections, allergies, and autoimmune flare-ups.
Nutrient & food issues
Dysbiosis can hinder nutrient absorption (e.g., B12, iron) and trigger food intolerances or sensitivities (e.g., gluten, dairy).
Skin & inflammatory risks
Imbalances may contribute to skin flare-ups, acne, eczema, LPS-related inflammation, SIBO, IBS, leaky gut, or gluten sensitivity.
Sleep & mood disruptions
Altered gut-brain axis function can impact serotonin and melatonin levels, affecting sleep quality, mood regulation, and stress resilience.
What You’ll Discover with the LONGSAL Gut Microbiome Test
This comprehensive report gives you a deep, personalized look inside your gut ecosystem.
Actionable insights, expert-curated strategies and detailed bacterial mapping make it easy to take control of your gut health.
From microbial diversity and immune function to metabolism, mood and inflammation risk, you'll uncover how your microbiome is impacting your overall health and what to do about it.
Microbial Health Overview
Microbial
Diversity Score: Measures how rich and balanced your gut ecosystem
is—high diversity = better resilience and digestion.
Species Richness & Evenness: Learn how many types of bacteria you have and whether they coexist in balance.
Dysbiosis Index: Indicates if your gut is out of balance (dysbiosis) and suggests recovery strategies.
Enterotype Classification: Reveals your dominant gut bacterial group (e.g., Bacteroides), which influences how you metabolize food and absorb nutrients.

Gut–Body Interactions
Gut-Immune
Axis: Evaluates how well your gut bacteria support your immune system
(~70% of immune cells are in your gut).
Inflammatory Potential: Assesses whether harmful bacteria in your gut are likely to cause inflammation via LPS (lipopolysaccharides).
Gut–Skin Axis: Identifies links between your microbiome and conditions like acne, eczema, and psoriasis.
Weight Management Indicators: Shows if your gut flora promotes healthy metabolism or may contribute to weight retention.

Risk Assessments
Leaky
Gut Syndrome: Checks whether your microbiome supports a strong gut
lining to prevent toxins from entering your bloodstream.
IBS and SIBO Tendencies: Evaluates microbial patterns associated with irritable bowel syndrome or small intestinal bacterial overgrowth.
Gluten Sensitivity Potential: Assesses the likelihood that gluten triggers symptoms or inflammation.
