This certified organic fiber blend provides the perfect balance of bulking and sweeping that nature intended. Insoluble fiber is responsible for sweeping the bowel clean and speeding the passage of waste from the body, while soluble fiber absorbs wastes and toxins. Other fibers that are primarily soluble, like psyllium, can actually dehydrate the colon and cause constipation. And because Organic Triple Fiber is rich with flax. it provides lignans, important antioxidants and phytonutrients that are not found in psyllium.
