SFI Health Therbiotic Probiotics (Formerly Klaire Labs)
Ther-Biotic has been a gold standard in professional-grade probiotic support for decades. Now under the SFI Health name (formerly Klaire Labs), these formulas deliver the same trusted, clinical-strength strains to support a healthy microbiome.
What sets Ther-Biotic apart is its proprietary InTactic® acid-proof delivery technology. This ensures that live, active organisms survive the harsh stomach acid and safely reach your lower gastrointestinal tract, where they can go to work.
