Glucomannan (Konjac Root)

Many individuals trying to lose weight recognize the benefit of adding more fiber to their diet. Fiber acts within the stomach and intestines to help you feel fuller for longer and to help the body process and eliminate food more efficiently. A lesser known but incredibly effective fiber source that is increasing in popularity is Glucomannan.

What is Glucomannan Powder?

Glucomannan, also known as Konjac Root, is a fibrous sugar that comes from the Konjac Plant found largely in tropical East Asia [1]. It has been widely used for hundreds of years as both a supplement and in certain foods as a thickener or gelling agent. Like other types of fiber, Konjac Root works in the stomach and intestines by absorbing water. In fact, Glucomannan is able to expand to up to seventeen times its original volume when placed in water [3].

Glucomannan Benefits

As with other fibers, Glucomannan's ability to expand significantly to absorb fluid makes it a great tool for suppressing appetite, as this expansion fills up the stomach, and sends a signal to the body that it no longer needs food [1, 2, 3]. For this reason, many people choose to supplement Glucomannan in attempts to promote weight loss. One study even showed significant weight loss in patients who had recently suffered from heart related complications [3]. Konjac Root is also commonly used to ease constipation, aid in controlling blood sugar levels, reduce the levels of lipids in the blood, and address thyroid complications [1].

Glucomannan Dosage

Glucomannan has been safely used for years by many individuals for a multitude of purposes [3]. The typically recommended dosage for Glucomannan is 2 grams taken 1-2 times per day, approximately 30-45 minutes before a meal. The benefit of using Konjac Root as a fiber supplement is that it requires a significantly smaller dose to achieve the same effects as other fiber supplements would [3]. When used appropriately, there are no toxicity concerns with this supplement. However, interactions with certain medications have occurred so it is best to consult your physician prior to use [1].
