Citrucel with SmartFiber provides the fiber you want for regularity, but without some of the negative side effects associated with other fiber supplements like a chalky taste or unpredictable trips to the bathroom afterward. That’s because SmartFiber is derived from cellulose, a naturally occurring element that promotes regularity without bloating and gas because it doesn’t ferment in your gut. Other fiber products use psyllium seed husk, which can and does ferment in the large intestine, causing excess gas and related undesirable symptoms. SmartFiber, on the other hand, will not. It is also non-allergenic and gluten-free. Citrucel is available in caplet and powder formulations with a great orange flavor. Citrucel is also available in a sugar-free formula so you don’t have to worry about excess calories either while getting regular.
