I personally found that there is different qualities of psylluim. I was using one that LOOKED like cream of wheat... you know kind of grainy. It also had a stale smell. This psylluim really clogged me up and it was painful even with one glass a day. If fasct I couldnt take it two days in a row.
I found a different brand. This psyllium was very light and fluffy, not powdery and grainy. It also tasted and smelled sweet. It swelled up and "jelled" up nicely too which the other stuff didnt.
The bad stuff I got from the healthfood store and was called inno-vite yeast busters... the new stuff I bought was from a drug store and I just saw it today in another healthfood store by Swiss Herbal, they make vitamins etc. too..
