I mentioned that Florastor was a good probiotic but I should mention that it contains good yeast and does not contain Bifidus or other things that some probiotics do. Although it's suppose to help certain ailments like leaky Gut if a you are taking other things like digestive enzymes, or goldenseal, Primadolphilus, or another probiotic, MMS or other products you may want to continue taking them. You can take it while taking antibiotics (which is not recommended to do for other regular probiotics.) But if you are looking to cure Leaky Gut with just Florastor and a multiple vitamin that may not be a good idea since a multiple vitamin cannot work on the gut and Florastor is a good yeast probiotic . And since digestive enzymes and other things are recommended that also play a good role in healing the gut. But Florastor has helped others who have taken it for other bowel disorders and infections in the digestive system.
