 Prebiotic fiber is on sale right now at EnforcedStore.com. So prebiotic fiber, by definition, increases the good bacteria in your gut while decreasing the bad bacteria. Other fibers on the market are not organic. They're bleached and they're modified with all kinds of toxic chemicals to break them down until they have little resemblance to their natural state. Not ours. Not ours. Ours is made with all organic natural fiber sources.
