Discover Your Inner Health
Personalized Insights from Your Gut Microbiome

The LONGSAL Gut Microbiome Test – Know What Drives Your Health

Your gut is home to trillions of microorganisms that control digestion, immunity, mood, and even skin health.

With the LONGSAL Gut Microbiome Test, you get deep insight into your inner ecosystem—in the comfort of your home.

It’s simple. It’s smart. It’s your body’s untapped intelligence.

The LONGSAL Gut Microbiome Test

is a scientifically validated, an advanced, clinical-grade and DNA-based stool analysis that maps your gut bacteria using Next-Generation Sequencing (NGS), identifying thousands of bacterial species from a stool sample.

It reveals what’s thriving, what’s imbalanced, and how your gut flora impacts your health (what that means for your digestion, immune system, mood, and metabolism) and provides personalized, science-backed nutritional and lifestyle recommendations.

You receive a science-backed report, easy-to-follow tips, and an option to retest and track progress.

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 that your gut health influences your entire body—from digestion to mental clarity to hormone function.

A Healthy Microbiome Helps:

Science-Backed 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

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.

Well-Being & Mental Health

Gut–Brain Axis: Detects imbalances that may affect mood, cognitive function, or stress resilience.
Physical Well-Being Score: Reflects how your gut bacteria support energy levels, recovery, and vitality.

Metabolic Health

Blood Sugar & Insulin Support: Identifies if your bacteria enhance or impair glucose regulation.
Blood Pressure Regulation: Evaluates microbial influence on cardiovascular markers.
Gut–Liver & Gut–Thyroid Axes: Indicates how gut flora affects detox, hormone balance, and metabolic stability.
