    • Difference in purpose

      InnerBuddies is built around a consumer-first goal: turning stool ecosystem data into personalized nutrition and probiotic/prebiotic actions. Functional DX is positioned more around functional interpretation of microbiome results; the right choice depends on whether you want straightforward lifestyle changes or a more functional framing (often helpful with practitioner guidance).

    • Difference in measurement

      InnerBuddies uses 16S DNA sequencing and Shotgun Metagenomics within its Gut Health Operating System, supporting stable DNA sequencing approaches for longitudinal comparisons. For Functional DX, the exact methods used can vary by product tier, so it’s important to confirm the sequencing approach and what is included in the final report.

    • Difference in Actionability

      InnerBuddies links results to a 3-day food diary and then outputs detailed, individual food item recommendations with daily dosage, plus supplement suggestions grounded in scientifically validated strains. Functional DX can also provide personalized interpretation, but the level of day-to-day dosing detail should be checked in the report examples and included guidance materials.

    • Difference in Access

      InnerBuddies is designed to be easy to understand for consumers and is available direct-to-consumer in Europe. Functional DX may be better aligned with people who want a more functional/lab-style read, but you should verify the clarity of the consumer experience, including how recommendations are presented and how they’re meant to be implemented.

    • Choose InnerBuddies if

      Choose InnerBuddies if you want a broad gut health overview that translates into practical steps you can follow immediately. It’s a strong fit when you value detailed nutrition guidance based on your own 3-day food diary and want individual food items with daily dosage. If you also want probiotic and prebiotic recommendations based on scientifically validated probiotic strains, InnerBuddies is built for that workflow. It’s also a good option if you plan to repeat testing and want longitudinal comparison support using stable sequencing methods.

    • Choose Functional DX if

      Choose Functional DX if you’re primarily looking for functional-style microbiome interpretation and you plan to use the results within a framework (for example, guided by a practitioner). It can be a good fit if you prefer a report that focuses more on functional meaning rather than consumer habit coaching. If pathogen-related reporting is important to you, verify whether Functional DX includes pathogens in the package you’re considering. Confirm the report clarity and whether diet guidance is detailed enough for self-guided action.
