Because of the nature of probiotics, it seems like more then anything else, brand quality, storage, etc are much more important then any other supplement. Of course, it all mattters with any supplement, but my vitamin C will still be equally effective left out of the refrigerator for 6 months whereas probiotics may not be. Does anyone have a good quality probiotic they use? I’m looking for one to treat Candida/yeast overgrowth. Thanks in advance.
