Yes, I use just the ground flax seeds, or if I'm out, I have FibreSmart, which is made with flax, as a standby until I get some more flax seeds. I take up to 2 tablespoons. I'm IBS-A so I really have to be careful with how much. Lately though I've been trying Benefibre but I tend to feel C with it. It might be because I'm not taking enough.
