I used it and highly recommend it. Not only took care of yeast without using any antifungals it also got rid of my stubborn sibo in a matter of a few days. It never seemed to lose effectiveness either.
I also think it is a great alternative for those who want to use s. boulardii but do not tolerate it.
I like it because you get the benefits of something like s boulardii but you can also use things that are strictly antifungal with it.
Be sure to take it on an empty stomach.
