I use Friendly Flora (and Digest Assure) and I attribute the fact that I did not get sick all winter due to Friendly Flora. Would not be without this product.
My daughter and I both have chronic GI problems, hers have been much more severe than mine this last year, she's been in the hospital and actually was unable to go to school. I started her on both of those, her DR agrees they would be fine(she's on a lot of meds) and her tummy is so much happier. The Friendly Flora is great. We order the ginormous bottles of both and she takes them 3 x a day, one of her meds is an antibiotic so that Friendly Flora has made her feel a LOT better. Anyway, I think they're both much better than anything I found in a drugstore. Read up on his info about Friendly Flora, it's exactly what the GI told us. Many probiotics never make it past the stomache because they aren't the kind of flora that will survive and they need to be with a food source that allows them to get further into the gut.
I was using another Pro Biotic product for years before he introduced his.I have gone back to that one, Less expensive and just as good.My Doctor recommended that one.Now for the Digest Assure, I like his product, but until I know what the TS's are, I can't/won't buy it.
