I take the GNC brand of silica (11g) - one pill a day - and after reading this thread, I am considering bumping that to one pill twice a day. You guys are not helping me here (LOL!!) I have a 2-day vitamin rotation going so that I can minimize my pill-popping. But now, I;m well on my way to consuming everything every day AND bumping the doses up! I even bought a little pill organizer/box to keep me going while I am on the go!! soo soo sad....
