Most of us seem to know that dietary fiber is an important part of our diet, but few of us understand how fiber contributes to good health, how much is enough of it, and which is the best supplement to choose.  The answers are complicated by the fact that there are different kinds of fiber (some of which aren’t technically "fibers" at all), broadly grouped into two subcategories — soluble and insoluble.  Both are indigestible, in that they pass through the stomach and small intestine undigested, but soluble fibers undergo fermentation in the colon, creating byproducts that have significant health benefits. Fiber therapy can help with constipation and diarrhea, diverticulitis, IBS and weight management.  Diets low in fat and high in fiber can help lower cholesterol and may help prevent colo-rectal cancers (there’s mixed evidence here). The American Dietetic Association recommends that you focus on eating plants to increase your fiber intake,
and not worry about which type is which.  But if you’re considering
fiber supplementation therapy, not all fibers are created equal. Which
one is best for you, depends on why you’re taking fiber supplements,
and which of the ancillary benefits might be of use to you. Your own response
and reaction to any fiber supplement may vary depending on the type of fiber in your supplement (psyllium, wheat dextrin, calcium polycarbophil, inulin, acacia), the form in which it comes (powder, caplet, chewable) and the amount you take.  Most fiber supplements are dosage-labeled based on use as a laxative, but for use in controlling IBS or diarrhea, you may need more or less.  Psyllium fiber supplements can claim cardiovascular benefits.  Inulin
can help the absorption of calcium, magnesium and iron while helping
feed the "good" bacteria in your gut. Fiber can also cause gas and bloating, as can the sorbitol used to sweeten some fiber supplements. So start small (and start with a supplement that is pure fiber, without additives or sweetners like sorbitol), and ramp up your dosage slowly, and experiment with the different types and forms of fiber, as well as the time of day you take it if
you’re not seeing any positive benefit after a week.  Personally, I prefer the tasteless additive-free dissolving powders like Benefiber,  FiberSure, and Heather’s Tummy Fiber, but also the convenience of Fiber Choice Chewables and Fibercon Tablets.
