The World Health Organization defines probiotics as “live microorganisms which, when administered in adequate amounts, confer a health benefit to the host.”†4 These microorganisms include both bacteria and yeast-based cells, which interact with the body differently.

Florastor® contains our unique active probiotic strain Saccharomyces boulardii lyo CNCM I-745, the friendly yeast found naturally on the skin of lychees and mangosteens (tropical fruits). Most of the other probiotics you’ll find on the market are bacterial probiotics that are either in pill form or in foods such as yogurt. When compared to bacterial probiotics, Florastor stays active even when taken along with antibiotics, to protect your GI tract especially when you need it most.†3 Visit the About page comparison chart to find out why Florastor is superior.

Florastor is a daily probiotic supplement intended to help promote the body’s own natural intestinal flora.1Anyone’s intestinal flora can become upset and vulnerable—whether from the daily flow of an active lifestyle (travel, stress, diet), disruption from a prescribed antibiotic, or nonspecific digestive issues. Florastor helps maintain peace in your intestinal tract by promoting intestinal balance and harmony.1 Florastor also supports intestinal function, which can result in healthy absorption of essential nutrients and water.†5,6

No, Florastor does not require refrigeration, making it travel-friendly. It is manufactured with a patented lyophilization process, similar to freeze-drying. This allows for storage at room temperature to guarantee an optimal level of living cells. Do not refrigerate Florastor after opening as this could expose the cells to moisture and compromise its three-year shelf life.

Within approximately 30 minutes after ingestion, each Florastor capsule dissolves in the stomach, allowing the yeast cells to help keep your intestinal tract on track. Florastor can only benefit you during days of use. Florastor is naturally eliminated through the digestive tract and is undetectable within five days after last consumption.†8

Florastor is gluten-free and the vegetarian capsule is derived from pine bark. A component of Florastor is sourced from milk for human consumption, however, only the lactose (milk sugar) is extracted. Florastor itself does not include milk proteins or whey. Because Florastor can increase digestive enzymes in healthy individuals, Florastor has been successfully taken by people sensitive to lactose.†5 However, a caution remains for individuals genetically incapable of producing the digestive enzyme, lactase.

Our manufacturing process does not include the risk of exposure or cross-contamination from corn, egg protein, fish, gluten, latex, meat, milk protein, nuts or shellfish. Florastor may contain traces of soy.
