It's tough to get enough fiber in one's diet unless you're a really good veggie person. :) The Jesen book says if you're not passing foot long, 1/2 to 1" in diameter stools, you're not getting enough. So right now I'm not getting enough! LOL!

Herbs should be taken at least two together as they work synergistically. If it's a tincture (alcohol), they digest easily, but if in a pill, they should ahve herbs to aid digestion and assimilation.
