Fiber tablets: Good and cheap?

I guess Metamucil, but their stuff to me is not natural and I dislike taking it. I prefer more natural fiber.
Is there any reason your relative has to take a pill? Can she/he drink something, or eat something?
Here’s a drink:http://www.netnutri.com/browse.cfm/4,2942.html Best brand ever.

I’ve found that the cheap generic brands are exactly the same. And also, the powder that you can mix into any drink/liquid works quite nicely too.

They just eat a low-fiber diet and have a hard time working it in. Moreover, a lot of fiber is never a bad thing! Thanks for the advice. I figured the cheap generic stuff is the same.
