I figured it was pretty harmless to throw a teaspoon or two in a glass of water 2-3 times a day, and it would make sure I drink more water.
As an appetite suppressant, I'm not lining up to give it supporting testimony, although that seemed to me to have the best science behind it with the pectin.
I'll try it for a month or so and see if I think it's doing anything. We'll see.
