I think you’ll hear mixed reviews. I think most agree Vsl3 is the best but it’s super expensive and some insurances don’t cover it (most of them!). Some docs recommend certain ones, other docs say anything is fine. 

One of my docs suggested Floristor and that’s worked well for me. My dads doc suggested Citrucel or something like that bc it has a certain number of microbes. If you do some research online you’ll find a suggested number that you’re supposed to hit- like 10 billion or something like that. I can’t remember the exact number but you catch my drift.

Some of them have to be refrigerated and some don’t. I like the kind that don’t bc then I can put it in my pill box with my other vitamins. It’s just easier for me to remember to take it that way. 

Good luck with your chocie! 

I take sporolac powder sometimes when I have to go out . Expect that I just take lactifiber 2tsp daily. Though I have VSL3# too but I dont really see anything extra for those extra bucks it costs me so i've stopped buying anymore of it.
