Ancient Nutrition SBO Probiotics Men's is a soil-based organism (SBO) probiotic formula designed to support digestive balance, immune function, and overall gut health in men. SBOs are hardy, spore-forming strains that are naturally resistant to heat and stomach acid, allowing them to reach the intestinal tract intact.
Why It's Worth Considering: The SBO delivery format offers stability advantages over conventional strains, and this men's formulation pairs probiotic strains with a prebiotic blend and botanicals relevant to male wellness.

More category questions
How many CFU do I need in a probiotic?
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.
Should I take probiotics with food or on an empty stomach?
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.
Can probiotics cause bloating at first?
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.
Do I need to refrigerate probiotics?
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.
Can I take probiotics with antibiotics?
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.
How long should I take probiotics?
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.
