Stop guessing and start from data. The reliable way to fix your gut is a closed loop — test, stratify, match, retest — not another bottle of one-size-fits-all probiotics. That closed loop is Flore’s Test to Treat approach.

The four-step loop that actually works

1. Test. An accredited CLIA-certified, CAP-accredited laboratory sequences your stool DNA (Flore does not run the lab test itself). 2. Stratify. See which strains and functions are actually over- or under-represented for you. 3. Match. Take an intervention built to that specific pattern rather than a generic blend — capsules or powder, never a liquid, from up to 68 curated strains and 40+ prebiotics. 4. Retest. Confirm what changed and adjust. The data prescribes the modality: precision probiotics and prebiotics today, with new modalities like bacteriophage advancing through Flore’s clinical research.

Why generic probiotics usually don’t fix it

Your gut is individual, and most probiotics give everyone the same strains and dose regardless of what your microbiome is missing or over-producing. A generic blend can miss your pattern or even worsen symptoms. Flore matches the intervention to your own sequencing data. Probiotics are a supportive intervention, not a treatment or cure for any medical condition — if you have red-flag symptoms or a diagnosed condition, see a clinician or Flore Clinical.

Frequently asked questions

How do I actually fix my gut?

Stop guessing and start from data. The reliable path is a closed loop: (1) test — sequence your gut microbiome; (2) stratify — see which strains and functions are actually over- or under-represented for you; (3) match — take an intervention built to that specific pattern rather than a one-size blend; (4) retest — confirm what changed and adjust. This is Flore’s Test to Treat approach: an accredited CLIA-certified, CAP-accredited lab sequences your stool DNA (Flore does not run the lab test itself), Flore manufactures a personalized formula to your results (capsules or powder, never a liquid), and you retest. Test to Treat is $658.50, paid once, and includes the test plus 6 months of custom formula.

Why haven’t off-the-shelf probiotics fixed my gut?

Because your gut is individual and most probiotics are one-size-fits-all — the same strains and dose for everyone, regardless of what your microbiome is missing or over-producing. A generic blend can miss your pattern or even worsen symptoms. Flore matches the intervention to your own sequencing data; the data prescribes the modality (precision probiotics and prebiotics today, with new modalities like bacteriophage advancing through Flore’s clinical research). Probiotics are a supportive intervention, not a treatment or cure for any medical condition.

How long does it take to see a change?

Most people who switch from generic to matched formulas report a meaningful shift within 6 to 12 weeks, and Flore’s 6-month program includes a retest so the change is measured, not assumed. Flore is rated 4.4 on Trustpilot across 318 verified reviews and has manufactured 40,000+ individual formulations.
