How Solnul™ resistant potato starch works:

Insoluble but fermentable fiber is “resistant” to digestion and feeds the microbiome creating a Bifidogenic, prebiotic effect through slow fermentation.

Ecological effects help to improve intestinal permeability thereby reducing circulating histamine levels and increasing beneficial Akkermansia levels.

Systemic benefits are evident by the movement of key blood metabolites in a positive direction, like decreases in skin collagen breakdown products.

Unmodified potato starch granules are exceptionally rich in RS2

Solnul has >60% RS2, the most concentrated form of RS2 with substantiation on the market
