How the Microbiome Quiz Works

The Microbiome Quiz assesses your current gut health behaviors across five categories that research consistently links to microbial diversity and gut-skin axis function: dietary fiber intake, fermented food consumption, plant food variety, probiotic use, and factors that negatively affect microbiome balance (antibiotics, ultra-processed food intake, high stress). Based on your responses, the quiz identifies your strongest areas and the gaps most likely to be limiting your microbiome health.

This is not a stool microbiome analysis — it does not sequence your gut bacteria or provide species-level data. It is a behavioral assessment tool that surfaces actionable patterns. The most clinically meaningful improvement you can make to your microbiome is increasing dietary fiber and plant food variety, which is entirely accessible without specialized testing.

For internal microbiome support alongside dietary changes, Seed DS-01 Daily Synbiotic is one of the more rigorously studied oral synbiotic options, combining clinically validated probiotic strains with a prebiotic outer capsule designed for colon delivery.

Who Should Use This Tool

This quiz is useful for anyone experiencing skin symptoms that may have a systemic inflammatory component — including persistent acne, rosacea flares, dull or reactive skin — and who wants to understand whether gut health behaviors might be contributing. It is also valuable for people who eat a reasonably healthy diet but have never specifically audited for microbiome-relevant factors like plant food diversity or fermented food intake.

The gut-skin axis works on a longer timeline than topical skincare — most people see gradual improvements over weeks to months of consistent dietary change, not overnight transformation. The quiz is best used as a baseline and re-scored after 6–8 weeks of intentional dietary improvement.
