I wouldn't pay that much if it didn't do wonders for me - there is no way! It all depends on what works for you. This is coming from a girl who shops at thrift stores, drives a 99 Ford, makes handmade Christmas presents, and even used to make my own compost for my garden ;).
But what are your ways of getting probiotics? I am sure moofqueen would love any pointers you have. I would be interested too as I am always looking for more ways to get in some good probiotics (kefir and fermented veggies are great, but we all want more variety in our diets!)
