Difference in purpose

InnerBuddies is built to connect your stool results to day-to-day choices, using a platform that combines microbiome testing with a 3-day food diary. Second Genome is primarily oriented around microbiome profiling and providing a detailed report, which users can interpret and then discuss with a clinician if needed.
Difference in measurement

InnerBuddies uses both 16S DNA sequencing and Shotgun Metagenomics as part of its Gut Health Operating System, supporting comparisons over time. Second Genome also uses DNA-based sequencing to characterize your microbiome, but the exact method mix and what’s emphasized can differ by product and reporting approach.
Difference in Actionability

InnerBuddies translates results into specific, personalized nutrition changes (including individual foods with daily dosage) and personalized probiotics/prebiotics based on scientifically validated strains. Second Genome can provide insights that are useful for tracking and interpretation, but the level of food-item dosing detail may not be as closely tied to a structured multi-day food diary experience.
Difference in Access

InnerBuddies is designed to be easier for consumers to understand, with guidance that aims to be directly usable. Second Genome may be more data-heavy and may feel more “report-first,” which can be ideal if you prefer to explore your results with less coaching-style translation.

Choose InnerBuddies if

Choose InnerBuddies if you want a gut microbiome test that turns findings into a practical plan you can follow. It’s a strong fit when you prefer consumer-friendly explanations and want personalized nutrition guidance linked to your own 3-day food diary—down to individual foods and daily dosages. It’s also suitable if you want supplement recommendations (probiotics and prebiotics) based on scientifically validated strains. If you’re in Europe and prefer a direct-to-consumer workflow, InnerBuddies is designed around that audience and experience.
Choose Second Genome if

Choose Second Genome if you’re primarily looking for detailed microbiome profiling and a structured report that you can interpret or share with a clinician. It can be a good option when you want microbiome insights more than a highly prescription-like nutrition dosing plan. If your priority is longitudinal microbiome comparison and you’re comfortable working with microbiome data, a report-oriented approach may fit well. Availability and EU data/privacy fit should be checked for your location and current offerings.
