Ds was on prescription probiotics when we started with crohns dx around age 7 or 8
It didn’t seem to do anything
So we stopped
A few years later
When nothing seemed to be helping
Gi added again as again
The same prescription brand etc... except the original owner of Vsl switched back to the original formula and called it visobiome
And it works like a charm
I will say though all the studies stated it doesn’t work for crohns but helps UC
Ds uses it to help rectal/sigmoid areas which is similar to UC
