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)”

4/5 Bloating & gasGentle

“• Gentle Stability: Using a low-fermentation prebiotic like Acacia fiber provides the structure your gut needs to stay regular and "flat" without the painful gas or flares that traditional fibers often cause.”

4/5 Taste & texture

“By using a diverse range of botanical tools, you give your system the structural support it needs to maintain a state of "glide." I use a specific combination of psyllium, acacia, and baobab because these ingredients transform into a slippery, hydrated gel.”
