Does taking fiber make you gassy?

According to expert insight, adding more fiber into your diet may trigger flatulence. This gas occurs when bacteria in the intestines process certain foods that are not digested by your gastrointestinal system when they pass into the colon.

Which fiber supplement does not cause gas?

Citrucel (methylcellulose) is mainly insoluble fibers that are nonfermentable, so it’s less likely to contribute to bloating and gas. Psyllium husk (Metamucil and Konsyl) is rich in both soluble and insoluble fiber. Generally, fiber supplements with mainly insoluble fiber may be a better option for constipation.
