Difference in purpose

InnerBuddies is designed for consumers who want a broad gut microbiome view plus actionable nutrition and supplement steps. Metametrix is also a stool-based microbiome test, but the emphasis may be more on its specific reporting/interpretation approach rather than diary-driven, food-item-level dosing guidance.
Difference in measurement

InnerBuddies states it uses 16S DNA sequencing and shotgun metagenomics in its Gut Health Operating System, which are established DNA sequencing approaches used in research. For Metametrix, the exact sequencing and reporting scope can vary by product, so the specific method and what it flags (e.g., certain organisms/pathogens) should be checked in the current report details.
Difference in Actionability

InnerBuddies links results to a 3-day food diary and stool samples to generate detailed nutrition guidance, including individual food items with daily dosage. Metametrix typically provides recommendations based on microbiome results, but the level of personalization tied to a food diary and the granularity of dosing guidance may differ.
Difference in Access

InnerBuddies is positioned as consumer-easy and available in Europe direct-to-consumer, which can reduce friction when you’re outside the US. Metametrix may be available in certain regions, but EU availability and the user experience can vary—so confirm shipping, reporting language, and privacy terms for your country.

Choose InnerBuddies if

Choose InnerBuddies if you want a consumer-friendly explanation of your gut microbiome ecosystem and you’re ready to act on it. It’s a good fit if you value detailed, personalized food guidance driven by your own 3-day food diary together with your stool sample results. It also makes sense if you prefer supplement recommendations that focus on scientifically validated probiotic strains and want prebiotic/probiotic suggestions aligned with the data. If you’re in Europe and want direct-to-consumer ordering and an EU-focused experience, it may align well with your needs.
Choose Metametrix if

Choose Metametrix if you’re primarily looking for a microbiome test with Metametrix’s interpretation/reporting style and you’re comfortable following its recommended next steps. It may be suitable if you want to repeat testing to track changes over time and compare broad microbiome patterns using Metametrix’s consistent pipeline. If you’re less focused on diary-driven food-item dosing and more interested in the overall profile and interpretation, Metametrix may match your preferences. Confirm current product scope—especially how it handles organism/pathogen reporting and what nutrition guidance includes.

Final Verdict

InnerBuddies and Metametrix both analyze gut microbiome DNA from stool, but they emphasize different user outcomes.
