Ortho Biotic by Ortho Molecular Products

If you’re looking for a probiotic for bloating and irregularity after travel, antibiotics, or high-stress weeks, this fits. The 20 billion CFU multi‑strain blend plus 2 billion CFU Saccharomyces boulardii (a beneficial yeast) is a good daily pick for loose stools, post-antibiotic recovery, and gut-immune support when you catch frequent colds. It’s also reasonable if your Comprehensive Stool Analysis shows low Lactobacillus/Bifidobacterium, or if low Ferritin or Vitamin B12 suggests absorption could be better.

The bacterial strains help crowd out gas-producing microbes and reinforce the mucus barrier, which is why many notice less bloating within 1 to 2 weeks. Saccharomyces boulardii survives stomach acid and typical antibiotics, so it can reduce antibiotic-associated diarrhea and the risk of recurrent C. difficile. Together they produce short-chain fatty acids (fuel for colon cells) and nudge the immune system toward tolerance, which often shows up as steadier stools and fewer urgent trips to the bathroom.

Take 1 capsule daily, any time, with or without food. During antibiotics, keep the probiotic but separate doses by 2–3 hours for best survival; continue for at least 1–2 weeks after the last antibiotic dose. Most people see changes in regularity and bloating within 7–14 days, with steadier benefits by 4 weeks. If you’re highly sensitive, start every other day for a week, then move to daily.

Avoid if you are immunocompromised, have a central venous catheter, or are critically ill, because probiotics and S. boulardii can rarely cause bloodstream infections in these settings. Skip while taking antifungals like fluconazole or nystatin, which inactivate S. boulardii. Yeast allergy is a no-go. If severe bloating worsens, consider evaluation for SIBO and check Calprotectin to rule out active gut inflammation before continuing.
