ProSol™ Colon Fiber™ combines the ingredients oat fiber, apple pectin, flaxseed and prune fiber to promote regularity. High in soluble fiber, oat fiber functions as a prebiotic and can help regulate blood glucose levels, remove toxins and lower cholesterol levels. Apple pectin, also a prebiotic, helps clean metals and chemical toxins from the intestinal tract. Along with large quantities of soluble and insoluble fiber, flaxseed contains a rich source of omega-3 essential fatty acids. Finally, prune fiber acts as a stool softener while Stevia and natural vanilla provide flavor.
