The Miracle-Mineral-Supplement does not kill of good bacteria, so you can actually take probiotics and Miracle-Mineral-Supplement at the same time. Since probiotics do not take any toll on the body or tax the system (Not that I know of anyhow) I think you would probably tolerate them well at the same time.
However, if you increase the Miracle-Mineral-Supplement and end up with diarrhea, then you will just end up getting rid of your probiotics too without getting benefit from that dose.
Anyhow, just wanted to let you know that they can be taken concurrently if you want.
