Potato Resistant Starch, dosed at 100mg here, is a type of starch that resists breakdown in the small intestine, behaving more like dietary fiber than the starches your body typically absorbs quickly.
Because it survives digestion largely intact, it reaches the colon where, like inulin, it becomes a fuel source for beneficial bacteria.
Resistant starch is also studied for its effect on post-meal blood sugar response, since less of it converts to glucose compared to fully digestible starches.
Where it sits in the formula: one of three ingredients in SodaTide, alongside Chicory Root Inulin, Probiotic Blend.
