For me and many others in the know, I am a major supporter for using a probiotic regardless of your overall health. Since there are a multitude of good things about using this supplement. Nevertheless you really need to be careful which you adopt given that a large amount of these are awful quality. The best one will certainly have multiple strains of healthy bacteria. And in case you can find one which is stable at room temps, then that is a perk.
