Query: Kind of hard to tell a difference until you add too much

I couldn't tell any difference from normal until I added too much ... and even then, it didn't accelerate my GI tract much, but it did give me INSANE gas. I'll sometimes toss a very small scoop into the 50g protein shakes I have and won't notice issues like that with small quantities, but I don't know if it helps. It's probably just the placebo effect or wishful thinking making me keep using it to justify the purchase. Eating "real" fiber by just upping the amount of veggies I eat has been the far better result compared to this powder for me. You can't taste it though, and it's fairly innocuous stuff, so if it doesn't give you the winds who knows it might help a little
