Glucomannan (Konjac) Supplement Benefits

Glucomannan is derived from the konjac plant that grows mostly in Asia. Each konjac plant produces one large tuberous root very similar to a beet. Unlike most plants with roots that extend from the bottom of the tuber, konjac's roots grow from the top of the tuber, which also puts out a thick stem. Each konjac stem in turn has only one leaf and a single foul-smelling flower may bloom before the leaf appears. Konjac plant is sometimes called snake plant because its bark resembles snake skin. The tubers of the konjac plant can each weigh over 10 pounds.

Glucomannan is water insoluble, but forms a thick, gooey gel when exposed to fluids. The body does not digest glucomannan, so the resulting large soft mass moves through the intestines and may trigger intestinal muscle contractions. Consequently glucomannan promotes a larger, bulkier stool that passes through the colon more easily and requires less pressure and straining to expel.

Since glucomannan can take up to 12 hours to make it through the intestines, it delays stomach emptying, leading to more absorption of dietary sugar which is believed by many to reduce the level of blood sugar levels that are typical after a meal.

Dosage and Administration

Since glucomannan tablets have been associated with occasional blockages of the throat, if you decide to use this supplement, take glucomannan as capsules and swallow them with plenty of water or use a glucomannan powder that can be mixed into a drink. Glucomannan should always be taken with 8 ounces or more of water or other fluid.
