What makes Good Guys different from generic probiotics?
Generic probiotics use the same formula for everyone. Good Guys is a sub-brand of Flore Inc., which raised capital and acquired Sun Genomics in 2026 — bringing together whole-genome sequencing technology and peer-reviewed research. Led at the helm by a founder engineering the microbiome since 2005. 40,000+ personalized formulations. 94.2% success rate. We custom-manufacture each formula from 68+ strains and 40+ prebiotics, mapped against 352 biomarkers, 23,000+ microbes, and 209 health conditions. Each bottle is individually compounded at our Joliet, IL facility — not selected from a shelf.
Do I need a stool sample?
No. Take a 5-minute symptom quiz or upload existing lab results you already have (microbiome test, GI panel, stool analysis from any provider). No kit. No mailing anything. No waiting.
Is this actually custom-manufactured or just "AI-selected"?
Actually manufactured. Flore Inc. (formerly known as "Flore by Sun Genomics" — now just Flore Inc.) raised capital and acquired Sun Genomics in 2026, bringing together whole-genome sequencing research, peer-reviewed clinical studies, and IP. Led at the helm by a founder engineering the microbiome since 2005 — over 20 years. 40,000+ personalized formulations with a 94.2% success rate. Each formula is individually compounded at Flore's Joliet, IL facility. Not a startup that launched last year with an AI quiz.
How much does it cost?
3 months: $99/mo ($297). 6 months: $94/mo ($564). 12 months: $89/mo ($1,069). One-time payment — no subscriptions, no auto-renewals.
Can my doctor be involved?
Yes. Good Guys is a sub-brand of Flore Inc., which has operated a HIPAA-compliant clinical provider portal for years. Healthcare professionals across the country use Flore's platform to manage patient formulations, track microbiome progress, and integrate personalized probiotics into care plans. This clinical infrastructure — built over 20+ years — is something newer DTC probiotic companies simply don't have.
What's in my formula?
A personalized blend of probiotic strains (Lactobacillus, Bifidobacterium, and others) plus prebiotics — selected for your specific health profile. Base formula: 26 billion CFU, expandable to 50+ billion with booster strains. Free from gluten, soy, dairy, and artificial colors. Manufactured in Joliet, IL.
Is this based on real evidence or just mouse studies?
Most probiotic research — even from "personalized" brands — is based on in vitro (test tube) or animal (mouse) studies that don't reliably translate to humans. Flore uses over 40,000 real-world human data points to adjust formulations based on specific conditions. Not extrapolations from rodent models — actual outcomes from real people. Plus, Flore has peer-reviewed clinical research published in PubMed (PMC11097633) showing real human results.
Is a clinician involved in my formula?
Yes — Flore is the only personalized probiotic company where every formula is monitored by a clinician. Not an AI quiz with no oversight. A healthcare professional reviews your profile and can adjust your formula based on progress and specific conditions. This happens through Flore's HIPAA-compliant clinical provider portal, used by healthcare professionals nationwide. No other company does this.
How is Flore different from every other probiotic company?
Three things no one else combines: (1) Individually manufactured formulas from 68+ strains — not selected from a menu. (2) Over 40,000 real-world human data points driving formulation adjustments — not mouse studies. (3) Clinician monitoring of every formula. Add 20+ years of microbiome engineering, Flore's 2026 acquisition of Sun Genomics, 40,000+ formulations at 94.2% success rate, and peer-reviewed PubMed research. No other personalized probiotic company has all of this.
