i know that kefir contains 10 probiotic-living cultures. how can i be sure which one would be the best for me? i actually just read another of your replies recommending this same probiotic jarrodophilis. do you know by chance, if they happen to contain any gelatin in the capsule? or any preservatives? also--as a C, do you notice a big difference in your BMs? idont mean to be forward--i would LOVE relief from my gas/bloating. those 2 in-combination *i think* is what causes my C!! those 2 things really stress me out alot. anyways thanks again for the reply! get back when you can--bye
