SpectraFiber™ combines purified and whole food plant concentrates containing a broad-spectrum of natural soluble fiber components with wide-ranging actions. SpectraFiber™ can be used to 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.
