Microbiome Testing

Unlocking the Secrets to Longevity and Optimal Health

The gut microbiome is one of the most influential factors in overall health, impacting everything from digestion to immune function, metabolism, and even brain health. Gut biome tests, like those offered by Biohm and other microbiome analysis companies, provide an in-depth look at the bacteria and fungi living in your digestive system. By understanding the composition of your microbiome, you can make targeted adjustments to optimize health and longevity.

What Can a Gut Biome Test Measure?​

A gut test analyzes the microbial landscape of your intestines, identifying key components such as:

  • Microbiome Diversity: The richness of different bacterial and fungal species, crucial for gut resilience.
  • Beneficial Species: Probiotics and commensal bacteria that contribute to digestion, immune function, and inflammation control.
  • Phyla Balance: The relative ratios of dominant bacterial groups (e.g., Firmicutes vs. Bacteroidetes), which impact metabolism and weight regulation.
  • Pathogenic Species: Harmful bacteria and fungi that may contribute to inflammation, infections, or gut dysbiosis.

How Your Gut Health Influences Longevity and Healthspan​

The gut microbiome is a critical regulator of aging and overall vitality. Scientific research has demonstrated strong links between gut diversity, inflammation levels, and chronic disease risk. Here’s how maintaining a balanced microbiome can enhance longevity:

1. Reduced Inflammation and Chronic Disease Prevention​

A well-balanced gut microbiome helps regulate immune responses, preventing chronic inflammation—a known driver of aging and conditions like cardiovascular disease, diabetes, and neurodegeneration. Studies show that individuals with higher gut diversity tend to have lower levels of systemic inflammation, reducing the risk of age-related diseases.

2. Improved Metabolic Health and Weight Regulation​

Certain gut bacteria influence metabolism, insulin sensitivity, and fat storage. A gut test can reveal imbalances in Firmicutes-to-Bacteroidetes ratio, which has been linked to obesity and metabolic disorders. Adjusting the microbiome through diet and prebiotic/probiotic supplementation can support healthier metabolic function.

3. Enhanced Brain Health and Cognitive Function​

The gut-brain axis plays a crucial role in cognitive health. A dysbiotic gut (poor microbial balance) has been linked to increased risks of depression, anxiety, and neurodegenerative diseases like Alzheimer’s. Optimizing gut bacteria through dietary changes can enhance mental clarity, memory, and emotional well-being.

4. Strengthened Immune Function​

Over 70% of the immune system resides in the gut. Beneficial bacteria contribute to immune regulation and pathogen defense. Gut testing can identify imbalances that may weaken immune responses or predispose you to infections and autoimmune conditions.

How to Adjust Your Health Based on Gut Test Results​

After receiving a gut test, personalized recommendations can help you restore balance and improve gut function. Here are some common adjustments:

  • Increase Microbiome Diversity:

    • Eat a variety of fiber-rich foods (vegetables, legumes, whole grains, fermented foods).
    • Rotate probiotics and prebiotics to introduce new beneficial strains.

  • Reduce Harmful Bacteria & Pathogens:

    • Identify and limit trigger foods that may encourage pathogenic overgrowth (e.g., excessive sugar, ultra-processed foods).
    • Incorporate antimicrobial herbs like garlic, oregano, and berberine under professional guidance.

  • Balance Phyla Ratios:

    • Adjust fiber intake to promote beneficial bacteria growth.
    • Introduce resistant starches (e.g., green bananas, cooked and cooled potatoes) to feed good bacteria.

  • Support Gut Barrier Integrity:

    • Consume collagen, bone broth, and L-glutamine to maintain gut lining health.
    • Manage stress levels, as chronic stress can weaken the gut barrier and lead to permeability issues.

Preparing for a Gut Biome Test​

To ensure accurate results, follow these guidelines before testing:

  • Avoid probiotic supplements for at least a week prior to the test.
  • Maintain your usual diet to reflect your natural microbiome state.
  • Follow sample collection instructions carefully to prevent contamination.
