Probiotics are like diet
For some they help
Others they do nothing or make them worse
most see improvements when the rectum is involved especially UC that is what VSL#3(now visobiome) was originally studied for.
vsl #3 was bought from the original owner 5 years ago (???)
The new owners changed the plant locations and the “formula “ of the probiotic
But never changed the claims that it was the same as the original version .
The FDA became involved and vsl#3 was stopped in production/sale in the US .
Due to this the original owner from the beginning started a new company visobiome which met all of the claims /studies for the fda with the original formula of probiotics
I know for my kiddo
The original vsl#3 worked
The changed version of vsl#3 (no milk protein present) did nothing
visobiome works for him as well
other probiotics out there have helped him a little but not as much as this stuff
