I use the Benefiber powder mixed with plain water. It's not gritty at all, but it does have an odd aftertaste. Not really bad, just strange. I don't use it for cholesterol; I use it for regularity if I'm having troubles. It works like a charm. I have tried the Benefiber edible orange tablets, which were really, really disgusting.
The only thing with these fiber supplements...DRINK LOTS AND LOTS OF WATER!!! You will get extremely constipated if you don't drown yourself with water. The eight 8oz glasses a day doesn't cover it for me. If I have two glasses of Benefiber, one in the morning, one in the evening (I use two tablespoons in each glass of the fiber, and it's about a 20-oz glass), I need to drink about 120 ounces of water throughout the day. I also make sure to follow the glass of water/Benefiber immediately with another glass the same size of plain water. I have also found a brisk 20 to 30 minute walk in the evening helps to keep "things moving" if you know what I mean.
The way my doc explained it, these fiber supplements add bulk to your stools. You need the water and activity to move that extra bulk along, or else you get constipated
Don't want to trade one problem for another, you know?
