Clinical study data
The whole point
Most gut supplements are powders you'll forget by Tuesday.
95% of Americans don't get enough fiber, and the gritty powders don't help. So we made a gummy you'll actually want to take, with slow-fermenting acacia fiber, probiotics, collagen and electrolytes in one. Here's why sensitive stomachs keep coming back.
02
FODMAP
Low-FODMAP & proud
Low/no FODMAP and well-tolerated by many people with IBS, even at higher doses, so sensitive stomachs have a gentler daily option.
