Most fiber just passes through—ours goes to work. Our Prebiotic Fiber Complex is a 5-in-1 blend of clinically studied resistant starches and fibers that delivers 7g of dietary fiber in every unflavored scoop. Unlike basic soluble or insoluble fiber, this blend ferments slowly in your gut, producing butyrate and other short-chain fatty acids that feed the beneficial bacteria which help strengthen your gut and support a healthy microbiome. That same slow fermentation is what helps keep you fuller longer, curb appetite, and support satiety between meals. We combine 5,000mg of NuFiber Resistant Dextrin, 1,250mg of Solnul Resistant Potato Starch, 1,250mg of Oat Extract (70% beta glucans), 500mg of Green Banana Powder, and 500mg of Acacia Fiber for complete prebiotic coverage. Unflavored and easy to mix, it stirs into water, juice, or a smoothie. Each 9oz (255g) jar provides 30 servings, crafted in our own GMP & FDA-registered facility in the USA and 3rd-party tested for purity.
