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.
