Yes I use it regularly. But I don’t have IBS, Crohns, or any other GI disorder. I use it to periodically populate my gut. So to answer “am I satisfied” is difficult. I don’t notice a difference with or without it, because none of us are consciously aware of our gut micro biome. I could say “well I haven’t been sick in years”, but who knows what else contributes to that.
Nowadays I just eat kimchi and kraut and hope for the best.
