I've had significant recovery from candida with Primal Defense probiotic and homeostatic soil organism product. I took acidophilous for years and all it did was keep me from getting worse. The Primal Defense has really turned the tide. It worked best when I took an ever-increasing dose up to 12 tablets per day.
I suppose it woule be most effective taken between flushes, so as not to flush out the new probiotic colonies before they are fully established.
