This has not been an active thread for awhile, but I thought I would add my two cents for anyone it may help.
I've used/tested/researched probiotics for 10 or 11 years. I started in the health food stores, but over the years I've found that the best and most consistent results come from the pharmaceutical grade probiotics like Align.
The health food store brands, particularly the refrigerated products, are not consistent. You can go to the store and see the probiotics in the cooler, but you don't see that it spent a couple of weeks in warehouses and unrefrigerated trucks getting to the store.
