Here's a link to an interesting study which included VSL#3.
Interesting meta analysis showing some promise for probiotics for maintaining remission and VSL#3 for actice UC!
I use Vsl#3 with orange juice whenever I feel off. It does work and tastes like an orange julius!! Also, If you have kids any time they are on antibiotics give this to them with orange juice. It helps keep their colons healthy. Best for prevention vs in a full blown flare up. Catch it fast!
