Introduction: One Science, Two Audiences In microbiome science, the same sequencing methods (16S rDNA, shotgun metagenomics) can feed very different end products. Consumers seek clear, actionable insights to support wellness and behavior change, while healthcare professionals require detailed, validated data to inform diagnosis and treatment. This article explains why reports must be tailored to each audience and how that affects language, visuals, recommendations, and follow-up. What tests measure Most gut microbiome tests report microbial composition (which taxa are present and their relative abundance), diversity metrics, potential pathogenic overgrowth, inferred functional capabilities (e.g., short-chain fatty acid production), and—especially in consumer products—personalized lifestyle suggestions. Why output differs 1) Language and context - Consumers benefit from plain language and context that prevents alarm: simple labels ("beneficial bacteria"), short explanations, and clear disclaimers help avoid misinterpretation. - Clinicians need full taxonomic names, methodological details, and literature references so findings can be interpreted against clinical thresholds and integrated with other diagnostics. 2) Visual design and data density - Consumer reports are graphic-forward (bar charts, traffic-light indicators, single composite scores) to support comprehension and behavior change. - Professional reports provide raw tables (OTU/ASV), diversity indices (Shannon, Simpson), PCA plots, and pathway overlays so clinicians can perform secondary analyses or correlate microbiome features with lab markers. 3) Actionable recommendations - For consumers: practical, low-risk suggestions such as increasing fiber variety or adding fermented foods, framed as general wellness strategies. - For clinicians: targeted interventions (specific probiotic strains, dietary patterns like increasing resistant starch, monitoring for H2S overproduction) accompanied by evidence citations and suggested follow-up testing. 4) Legal, safety, and ethical considerations Consumer-facing outputs must avoid diagnostic claims and reduce the risk of unnecessary medical interventions. Conversely, professional reports may include diagnostic support when delivered in a clinical context and accompanied by methodological transparency. Dual-tier ecosystems Modern platforms increasingly offer dual-tier models: a consumer tier that emphasizes engagement, recipes, and habit-building tools, and a professional tier that supplies clinical-grade sequencing, EMR integration, longitudinal tracking, and functional pathway analyses. This approach preserves scientific rigor while maximizing appropriate use by each audience. Example and integration A consumer might receive a concise recommendation to "add fermented foods and diversify fiber sources," while their clinician sees a detailed note about low Faecalibacterium prausnitzii abundance and suggestions to monitor inflammatory markers. These complementary outputs reduce misinterpretation and better support both behavior change and clinical decision-making.

Clear consumer-facing interpretation and robust professional reporting are complementary components of responsible microbiome services.
