Scan bran definitely do work to keep you regular. I eat just one a day, sometimes two. And it works a treat. I usually have my HexA of cheese on top. But even if I don't have anything to put on it, I'll dunk it in my cup of tea just to get it down. It doesn't taste great like that, but the important thing for me is to get it in my system. I definitely notice a difference when I don't have them.
