Ther-Biotic Senior Formula by Klaire Labs/SFI Health is a multi-strain probiotic specifically formulated to support the shifting gut microbiome needs of older adults. It delivers a blend of Lactobacillus and Bifidobacterium strains in a hypoallergenic capsule, designed to support digestive balance, regularity, and immune function.
Why It's Worth Considering: Klaire Labs is a practitioner-trusted brand known for rigorous strain identity verification and excipient-free formulation, this formula emphasizes Bifidobacterium species that tend to decline with age.
Adults: 1 capsule daily with food or as directed by a healthcare professional. Children: As directed by healthcare professional.
| Feature | Multi-Strain (this) | Spore-Based | Saccharomyces | Single-Strain |
|---|---|---|---|---|
| Survivability | Moderate (refrigerate) | Excellent (shelf-stable) | Excellent (yeast-based) | Moderate |
| Best For | General gut health | Antibiotic recovery | Diarrhea, C. diff | Targeted conditions |
| CFU Range | 10-100 billion | 2-5 billion (potent) | 5-10 billion | 1-50 billion |
| Research | Extensive | Growing | Strong (S. boulardii) | Strain-specific |
For general health maintenance, 10-20 billion CFU is sufficient. For therapeutic use (post-antibiotics, IBS, immune support), 50-100 billion CFU is recommended. More important than CFU count is strain diversity and survivability, a 5 billion spore-based probiotic may be more effective than a 100 billion conventional strain that doesn't survive stomach acid.
Take with food or within 30 minutes of eating. Food buffers stomach acid and increases probiotic survival by up to 100x. A small amount of fat in the meal further improves survival. Exception: spore-based probiotics (Bacillus strains) are acid-resistant and can be taken anytime.
Yes, temporary bloating, gas, or changes in bowel habits during the first 3-7 days is common and actually a positive sign. This 'die-off' reaction occurs as beneficial bacteria displace harmful organisms. If symptoms persist beyond 2 weeks, reduce the dose by half and gradually increase.
It depends on the strain. Most Lactobacillus and Bifidobacterium strains require refrigeration for viability. Spore-based probiotics (Bacillus) and Saccharomyces boulardii are shelf-stable. Check the label, if it says 'viable at time of manufacture' rather than 'at time of expiration,' refrigerate.
Yes, in fact, it's strongly recommended. Take the probiotic 2-3 hours apart from the antibiotic dose (so the antibiotic doesn't kill the probiotic). Saccharomyces boulardii is particularly resistant to antibiotics. Continue probiotics for at least 2-4 weeks after completing the antibiotic course.
For acute use (post-antibiotics, traveler's diarrhea), 4-8 weeks minimum. For chronic conditions (IBS, immune support), ongoing daily use is recommended. Probiotics don't permanently colonize, they exert benefits while you take them and for a limited time after stopping. Think of them as a daily maintenance supplement, not a one-time fix.
