Does more fiber always help with GLP-1 constipation?

Fiber is often discussed when people are trying to manage constipation on a GLP-1. It can help, but adding a large amount all at once may be uncomfortable when you already feel full quickly.

Psyllium and some other fiber supplements may support regularity. Increasing the amount too quickly, especially without enough fluid, can also mean more bloating, gas or harder stools.

If you use a fiber supplement while taking a GLP-1, what type and amount have you found easiest to tolerate?
