From what I've read, it is marketed to be used when you have to take antibiotics, so like for two weeks. My naturopathic doctor had me taking one-half a dose each day(although I misunderstood the first week and used a full dose)(he said he suggested one-half because of the cost) for two months, then he says he'll switch me to a pill which I expect to take forever. Some healthy people take probiotics daily just to help digestion.
It's about $35 for seven full doses. It's a powder to mix in water or anything else, comes in refrigerated packets, tastes good.
I also stopped the gluten at the same time, so I can't know for sure what worked, but I am doing great, better than I have in years.
