If you suspect that you’re not getting enough of it (most of the U.S. population isn’t), supplementation is wise. But not all fiber supplements are created equal. We like the simplicity of SupraFiber from Sunsweet Naturals. It’s made with fiber from whole fruits — prunes, apples, pomegranates, açai — rather than psyllium husk, a common natural ingredient that can be harsh for those with sensitive digestive tracts. $20 at your local natural grocery.
