Florastor is a yeast based probiotic supplement, with the main ingredient saccharomyces boulardii lyo. The product contains lyophilized Saccharomyces boulardii, hence the name. The lyophilisation makes the yeast last longer, and less susceptible to temperature changes. The shelf life of Florastor is better in consequence.
Flostator is great to prevent stomach and intestinal problems assosiated with antibiotics. Florastor can be taken with antibiotics, maintaining efficiency, unlike bacteria based probiotic supplements.
