SpectraFiber™ combines purified and whole food plant concentrates containing a broad spectrum of natural soluble fiber components having wide-ranging actions with prebiotic effects supporting a healthy gut microbiota. SpectraFiber™ can help boost soluble fiber intake in a concentrated, easy-to-take capsule form. Unlike many common bulk fiber supplements, SpectraFiber™ contains no bran, cereal grains, or psyllium seed that some individuals find irritating to the GI tissues or may need to avoid due to allergic reactions.
