Gut Microbiome Testing
Understand Your Gut. Personalize Your Nutrition.
Your gut microbiome is the community of microorganisms living throughout your digestive system. These microbes interact with the foods you eat and are connected to digestion, metabolism, immune function, inflammation, and overall health.
Gut microbiome testing can provide a snapshot of your microbial community and help identify patterns that may be useful when developing a personalized nutrition strategy.
Why Your Gut Microbiome Matters
Your gut is home to trillions of microorganisms that interact with each other, your diet, and your body.
A healthy gut microbiome is not simply about having more bacteria. Microbial diversity, balance, and the broader ecosystem all matter.
Your microbiome can be influenced by factors including:
Dietary patterns
Fiber and prebiotic intake
Fermented foods
Lifestyle
Medications
Environment
Individual health history
Understanding these factors can help provide a more complete picture of your overall health.
What Is Gut Microbiome Testing?
Gut microbiome testing analyzes a stool sample to provide information about the microorganisms present in your digestive tract.
Depending on the testing platform, results may provide information about:
Microbial Diversity
An overview of the variety of microorganisms detected in your sample.
Microbial Composition
Information about the types and relative abundance of microorganisms identified.
Gut Health Markers
Depending on the test used, additional markers may provide context about digestive or intestinal health.
Nutrition-Relevant Insights
The results can be considered alongside your diet, symptoms, health history, and goals when developing personalized nutrition recommendations.
Testing Is One Piece of the Bigger Picture
A microbiome test is not a complete picture of your health, and it should not be interpreted in isolation.
Dr. Rosa considers microbiome results alongside your:
Nutrition and dietary patterns
Digestive symptoms and health history
Lifestyle and activity
Health goals
Relevant clinical information
Other testing, when appropriate
This allows the results to become part of a broader, personalized nutrition strategy rather than a list of isolated recommendations.
