Fiber Formula contains all-natural fibers and herbs that safely absorb and eliminate toxins and improve colon function. Fiber is effective only when fully dispersed in the colon to adhere to and eliminate toxins and enhance the removal of waste products. Our patent-pending True Dispersion technology ensures the fiber is completely released and dispersed throughout the colon for thorough cleansing.This is a clay-free formula. That's important, since detoxification products containing clay can deplete the body of healthy minerals, and often contain high levels of lead and other toxins.
