Unlike most fiber supplements, UniFiber® is an insoluble fiber – similar to the types of fiber found in nuts and whole grains. Insoluble fiber does not require water to do its job, so it does not cause gas or bloating associated with many other fiber supplements. UniFiber® adds bulk to your stool which helps food pass more quickly through the stomach and intestines. Also, since UniFiber® is an ultra-fine, grit-free, tasteless powder, it can be added to your favorite recipe without changing the flavor.
