I've heard some good things about prebiotics and probiotics - for example, here. I also came across this line...
As with any dietary supplement, be aware that probiotic supplements are regulated as foods, not drugs - WebMD
So, here's my question, can you overdose on prebiotics or probiotics? How much would you have to take? I heard they're natural, but still wanted to know, if having more of those natural bacteria a problem at all? Could it depend on the specific type of bacteria?
