L.R.
I personally have been on them for awhile and love them for my IBS. I recently put my 6 and 2 yr old on Culturelle for kids. They seemed to be getting sick a lot and have read good stuff about probiotics helping with immunity. You can buy them at most drugstores, I bought my at Walgreens. They come in individual packets and you just mix them in a drink, it has no taste. I like it better than kefir and yogurt because it doesn't have any sugar in it and it has a lot more good bacteria in it. The only downside it that it is a bit pricey, it was $26 for 30 packets at Walgreens, but I have been able to find it for like $17-18 at LuckyVitamin.com. Hope it helps.
