What owners say about Acacia fiber

4/5 Gentle
“Acacia is the other gentle one worth knowing about, it ferments so slowly that even sensitive guts handle it well and it actually feeds Bifidobacterium selectively.”

5/5
“I was recommended heathers tummy fiber and that has been working so much better for me, I believe it’s acacia powder and apparently is much gentler for folks with ibs symptoms (or SIBO in my case)”
