What Microbiome Testing Reveals About Your Body
Author: Dr. Kolin Durrant, Integrative Care Director, Doctor of Acupuncture & Chinese Medicine
In the last decade, microbiome testing has evolved from a wellness trend into one of the most powerful diagnostic tools in holistic healthcare. By examining the diverse population of microorganisms that live in your digestive tract, this testing provides insight that extends far beyond digestion. It reveals how your body is functioning at the cellular level and helps uncover the root causes of imbalances affecting energy, immunity, metabolism, and long-term vitality.
At Saffron & Sage, we use microbiome testing to transform data into personalized care. Instead of chasing surface-level symptoms, we look beneath the surface to understand the mechanisms driving your health concerns. With this insight, we empower our members to take ownership of their wellbeing through informed, natural interventions.
The Gut: A Mirror of Your Internal Health
Your gut microbiome is a dynamic ecosystem composed of trillions of microorganisms that interact with nearly every organ system. When this ecosystem is in harmony, your body tends to function smoothly. When disrupted, however, the effects may show up as fatigue, inflammation, poor nutrient absorption, or mood fluctuations, often well before a formal diagnosis is ever made.
Microbiome testing offers a snapshot of this inner environment. It allows practitioners to assess how effectively your gut bacteria are supporting digestion, producing vitamins, regulating immune responses, and contributing to metabolic function. These results form the foundation of a personalized plan for healing, prevention, and optimization.
What Microbiome Testing Can Tell You
Microbiome testing does not simply measure the presence of bacteria. It decodes biological activity that shapes every system in the body. Here are six key insights this testing can provide:
1. Metabolic Efficiency
Your microbiome directly influences how efficiently your body converts food into energy. Beneficial microbes help break down complex carbohydrates, generate short-chain fatty acids (SCFAs), and support blood sugar regulation. When these species are diminished, the result may be blood sugar instability, energy crashes, or difficulty maintaining a healthy weight.
A 2021 review in Nature Medicine found that individuals with higher gut microbial diversity had better metabolic health and lower risks of obesity and heart disease (Nature Medicine – Gut Microbiome and Metabolic Health).
By identifying the dominant species in your gut, testing can reveal whether your metabolism is functioning efficiently or whether targeted nutrition and lifestyle adjustments are needed to restore balance.
2. Inflammatory Activity
Low-grade inflammation often originates in the gut. When harmful bacteria outnumber beneficial ones, they can compromise the gut lining and overstimulate the immune system. This process may lead to joint pain, digestive bloating, skin issues, or mental fog—often without clear origin.
Microbiome testing pinpoints markers of gut-based inflammation and highlights species known to provoke immune reactivity. With this information, practitioners can introduce anti-inflammatory foods, targeted probiotics, and herbal therapies that help resolve inflammation at its source.
3. Nutrient Absorption and Vitamin Production
Beyond digestion, your microbiome plays a central role in nutrient metabolism. Specific bacteria help produce vitamins like B12, folate, and vitamin K, and others break down fibers to enhance nutrient absorption. If your gut is out of balance, even the most nutrient-rich diet may not be absorbed properly.
Testing helps clarify whether your body is producing and absorbing nutrients as it should. It guides practitioners in designing protocols that include therapeutic foods, digestive support, and supplementation to optimize nourishment.
4. Stress and Mood Regulation
The gut and brain are in constant communication. This gut-brain axis involves specific bacteria that help produce neurotransmitters like serotonin and GABA, both of which regulate mood, sleep, and stress resilience.
When these microbial populations are disrupted, individuals may experience increased anxiety, poor sleep, or heightened emotional reactivity. A 2022 study in Nature Reviews Neuroscience affirmed the connection between microbial diversity and emotional regulation, suggesting that gut bacteria can shape the stress response (Nature Reviews Neuroscience – Gut Microbiota and the Brain).
Microbiome testing can uncover patterns that explain the mental-emotional experience, allowing for integrative therapies that support both neurologic and digestive health.
5. Immune System Regulation
Roughly 70 percent of the immune system is housed in the gut. This makes microbial balance critical for maintaining immune tolerance, defending against pathogens, and minimizing autoimmunity.
Testing can reveal whether the immune system is being triggered unnecessarily or failing to respond adequately. Practitioners use this information to recommend immune-supportive strategies such as fermented foods, probiotic strains, and gut-rebuilding nutrients that reinforce resilience from within.
6. Detoxification and Hormonal Balance
Certain gut bacteria assist with detoxification by breaking down toxins and facilitating their excretion. Others help metabolize hormones like estrogen and cortisol, playing a vital role in maintaining endocrine balance.
When these microbial allies are compromised, toxins and hormones may recirculate through the body, leading to fatigue, acne, bloating, mood swings, or irregular cycles. Testing offers clues about whether your detox pathways are clear or congested, and whether your hormonal metabolism is functioning optimally.
Practitioners can then support liver function, promote regular elimination, and use botanicals to reestablish hormone clearance and stability.
How Practitioners Use This Data
At Saffron & Sage, microbiome testing is a tool for transformation, not just diagnosis. The results are interpreted through the lens of integrative care and used to build a customized plan that may include:
Nutritional therapy to support bacterial diversity and nutrient absorption.
Herbal and probiotic protocols to reduce inflammation and rebuild gut lining integrity.
Energy work or mindfulness therapy to address gut-brain imbalance and reduce stress reactivity.
Lifestyle and sleep guidance to reinforce the body’s natural healing cycles.
Each protocol is rooted in the unique data of your body, ensuring that care is both personalized and sustainable.
A Deeper Look Into Preventive Health
One of the most powerful benefits of microbiome testing is its ability to detect imbalances before symptoms escalate. Subtle shifts in microbial populations often precede more serious metabolic or autoimmune conditions.
The National Institutes of Health Human Microbiome Project confirmed that certain microbiome patterns are predictive of disease resilience. By addressing microbial imbalance early, individuals can prevent the development of chronic conditions such as metabolic syndrome, inflammatory bowel disorders, or autoimmune dysfunction.
This is the essence of integrative care: identifying root causes early and treating the body as a whole.
What Your Gut Is Trying to Tell You
Your microbiome sends messages through your digestion, energy levels, emotional state, and immune response. Testing helps translate those messages into clear, actionable information. It allows us to move beyond symptoms and into a deeper understanding of what your body is truly asking for.
At Saffron & Sage, our team uses microbiome testing to bring data and intuition together, offering a path toward vitality, resilience, and true healing.
