Solnul™ Information

Solnul® is a naturally occurring resistant potato starch classified as RS2, an often overlooked but essential category of dietary fiber that is insoluble but fermentable. The human microbiome evolved to thrive on resistant starch, a foundational fuel consumed through starchy whole foods. Modern processing, preservation, and cooking practices have steadily reduced resistant starch in the human diet. Potatoes, long consumed across cultures, are nature’s richest source of RS2. Solnul® is a whole-food, well-tolerated, patented, Upcycled Certified®, FODMAP Friendly prebiotic containing 63% fiber. It’s been clinically validated through multiple research methods to support the microbiome. Solnul® is your microbiome’s favorite food. Only 5% of Americans meet the recommended daily intake of fiber, yet 64% are actively trying to consume more. This gap reflects rising gut‑health awareness, compounded by social media, and its links to regularity, immunity, and metabolic health. Traditional fibers often compromise taste, texture, or tolerability, or fail to deliver meaningful health benefits. Quality of fiber matters more than quantity. Resistant starch is the unsung hero of fiber - insoluble yet fully fermentable. Solnul® is the only branded resistant starch offering superior sensory performance, excellent tolerability, and research to support improved regularity, gut barrier function, nutrient absorption and metabolic health. Solnul® works by feeding the microbiome through slow, targeted fermentation. As an insoluble but fermentable prebiotic fiber, it selectively increases beneficial bacteria such as Bifidobacterium and Akkermansia while optimizing a healthy microbial balance in the GI tract. This ecological shift contributes to improved gut barrier function, normal metabolic function, and more efficient nutrient absorption. Human clinical research has shown that Solnul® also influences circulating blood metabolites, including reductions in histamine and free fatty aci
