I've been taking probiotics off and on for a couple of decades, once I found out how brutal antibiotics are on intestinal flora and our bodies in general. I've tried almost every brand and type out there, and usually come back to Zahler, who are reliable and offer good value.
I always prefer to get my probiotics from living, whole food sources---yogurt, miso and other fermented foods are the best sources I've found. But sometimes you need supplemental pills, especially when traveling, and especially in areas with bad water. That's where these pills shine; they're solid tablets, and unlike most probiotics, which come in caps, these don't have to be refrigerated after opening.
Love this product! I used to use align probiotic and it never really worked for me and still had digestion problems. But BioDophilus helped improve that and I don't feel discomfort anymore. Highly highly recommend this! Cleared up all my stomach pains and problems.
