Yes, VSL#3 has their own website. You can either order from there or you can do a search there of local pharmacies that carry it. My local Walgreens got it for us, though they took too many weeks to get it.
I believe VSL has something like 8 strains and 450 billion viable organisms. I have read here, though, that one should take the capsules rather than the powder pouches. I think it was corn starch or some other additive in the pouch version that folks said wasn't so good for Crohnies. The capsules have no corn starch. They ran about
$45 for 60 capsules. The capsules are 1/2 the strength of the powder pouches--225 billion critters in each one. When my son took VSL he only took one capsule a day.
We have used Theralac for nearly a year now. It also has its own website and that's where I order it from--Therabiotics, in Victoria, MN. It has something like 6 strains and 20 billion CFUs (colony forming units) in an acid-proof formulation...or something like that. We used VSL in addition to Theralac a few months ago when my son had to take an antibiotic for a bronchial infection. We had good results with it, too.
Sarita mentioned her bathroom trips were cut in half with VSL. My son reported this, too, and he typically goes only about
3 times a day. He actually wasn't so sure he liked that number cut in half! Go figure!
