I was on a site the other night that sells kefir,,but they talk about lots of things,anyway,they said you should NOT take kombucha and kefir at the same time,,like just use one or the other,but didnt go on to explian why,I realize I wouldnt probably want to eat kefir and wash it down with kombucha,but I usually use both each day,and havent died or anything so what do you all think?
