Florastor Probiotics

Florastor is one of the most widely recommended probiotic brands, built around a single well-studied strain: Saccharomyces boulardii CNCM I-745. Unlike bacteria-based probiotics, this beneficial yeast isn't affected by common antibiotics, which is why so many people reach for it during and after a course of antibiotic treatment. Each capsule delivers 250 mg of the strain, the amount used in much of the clinical research behind the product.

Our selection covers the everyday Florastor Daily Probiotic Supplement in both the 50-capsule bottle for regular, ongoing use and the 20-capsule box that's handy for travel or a short-term course. Because the strain is naturally resistant to stomach acid, the capsules don't require refrigeration and can be stored at room temperature — a practical advantage for anyone who wants gut support they can keep in a bag, a desk drawer, or a suitcase.

People typically choose Florastor to help maintain normal digestive balance, support gut flora while taking antibiotics, and ease occasional digestive upset. The standard adult routine is one to two capsules daily, and capsules can be opened and mixed into cool food or drink for those who prefer not to swallow them whole. It's a common pick for travelers concerned about changes in diet and water, and for anyone rebuilding balance after illness.

Florastor is suitable for daily use and is gluten-free, though anyone with a yeast sensitivity or a compromised immune system should check with a clinician first. If you're comparing options, look at the strain, the milligram strength, and the count per package to match the format to how long and how often you plan to take it.
