I've been taking Fiber Choice regularly for about 7 months now. As far as being able to compare them to Citrucel or Metamucil, it really depends on what types of fiber your body responds best to as we're all different. These do okay for me, and I'd taken FiberCon previously and ended up having D after 6 days. It seems that I'm always destined to have slightly more gas than the average individual, and I don't know how much of that is to blame on Fiber Choice itself. I don't know if that helped much.Ashley
