I am not sure there is much of a difference in potency, Lannie from the Yeast Connection swears that P73 is the best and I find it is the least unpleasant...but very expensive. I think they are all about equal in effectiveness and they all burn the tongue like crazy. I sometimes put it into a capsule if I don't want to smell like a pizza or dish of spaghetti. And I also give it to my husband that way, he cannot handle the taste at all...and it burns him worse cause he probably has thrush.

There was one that I just hated, it was the worst, it had a gold label and was called Enerex or something like that....hope you don't get that one..... <img src="/ubbthreads/images/graemlins/blush.gif" alt="" />
