What is Glucomannan?

Glucomannan is a water-soluble dietary fiber that is extracted from the roots of the elephant’s foot yam plant (Amorphophallus peoniifolius) which is also known as konjac root. Around 40 percent of the elephant foot yam’s dry weight is made up of a glucomannan.

The plant is native to South Asia, Africa, and tropical Pacific Islands. It is widely used in Indian medicine for addressing numerous ailments including amenorrhea, hemorrhoids, indigestion, and inflammation. It is used throughout many Asian countries in regional cuisine. In the United States, glucomannan is available as a dietary supplement and is added to food products such as flour and pasta. It is also used as in food as a thickener and an emulsifier.

Glucomannan is a non-starch polysaccharide. Although it is not very digestible, it does provide several dietary elements. The most important of which is fiber, which can change how other nutrients are absorbed in the GI tract and may help to enhance bowel motility.

Fiber is a very important part of the human diet because it helps digestion, prevents constipation, and cleanses the colon.  When you take a fiber supplement, such as glucomannan, it is not digested by the body but passes through the stomach and the intestines intact.

Uses & Benefits of Glucomannan

Here is a rundown of glucomannan benefits:

Weight loss: Like many dietary fibers, glucomannan is often touted as a weight-loss supplement. This is mainly because of the connection between dietary fiber and satiety. For example, a 2000 study published in the Journal of Nutrition showed that because soluble fiber absorbs water, causing it to bulk up, it easily promotes a feeling of fullness, which in turn, means less food is consumed. Fiber also delays stomach emptying, so the feeling of fullness in prolonged. Glucomannan is thought to be more effective than other soluble fibers because its high viscosity allows it to bulk up more. Soluble fiber such as glucomannan also contains very few calories. Studies have shown that glucomannan feeds friendly microbacteria in the gut and intestines, which promotes the production of butyrate, which is a fatty acid that is thought to lower the risk of weight gain by increasing energy expenditure. More research is needed.

Heart health: A systematic peer review of fourteen clinical studies involving glucomannan revealed that the substance supports heart health in a number of different ways.

  • It lowers total cholesterol.
  • It lowers bad LDL cholesterol.
  • It lowers triglycerides.
  • It lowers fasting blood sugar levels.

This means that glucomannan has the potential to reduce the risk of heart disease. More research is needed.

Prebiotic effects: As mentioned above, glucomannan provides a food source for beneficial intestinal bacteria. The term for this is prebiotic. Beneficial bacteria (probiotics) are essential not only for GI health but also for a healthy immune system. Prebiotics such as glucomannan pass through the upper GI tract undigested because they cannot be fully broken down in the body. However, once glucomannan reaches the colon, the gut microflora begins a process of fermentation and glucomannan is broken down to create new probiotics. A 2008 study, published in the Journal of the American College of Nutrition, showed that glucomannan supplementation boosts the intestinal concentration of probiotics, specifically lactobacilli, and bifidobacteria. Higher populations of intestinal bacteria can have many health benefits including:

  • Improving digestion
  • Strengthening the immune system
  • Lowering the risk of heart disease
  • Maintain healthy cholesterol levels
  • Lowering the incidence of inflammatory and autoimmune reactions

Constipation relief: Several studies have shown glucomannan to be an effective means of addressing constipation without causing side effects.

Diabetes: One way that glucomannan may help with diabetes is by delaying the stomach’s emptying process. This means that sugar is absorbed more gradually, and blood sugar levels are lower after meals. In a 1999 study published in Diabetes Care, participants suffering from diabetes type 2 were treated with a low-fat diet and conventional drug therapy. They were also given biscuits containing glucomannan fiber. The results indicated that glucomannan may improve blood sugar control. More research is needed.

How to Take Glucomannan

Because glucomannan supplements are not regulated by the FDA, there is no standardized glucomannan supplement dosage. The suggested glucomannan dosage is typically lower than other fiber supplements because glucomannan expands much more when it absorbs water (up to 50 times its own weight).

A 2005 study published in Alternative Therapies in Health and Medicine indicates that a glucomannan dosage of 2-4 grams per day is suitable for weight loss in obese individuals. To ease constipation, 3-4 grams per day is usually recommended.

If you have not used glucomannan before, it is best if you start out with one small dose each day; about half a level teaspoon (2 grams). You should be sure to take it with plenty of water, to avoid the risk of choking. You should take it at least 30 minutes before eating.

Glucomannan Side Effects and Precautions

Glucomannan is generally considered safe when taken orally following the manufacturer’s instructions for up to four months. Minor side effects may include:

  • Diarrhea
  • Bloating
  • Flatulence

Glucomannan in solid form may be unsafe if you have difficulty swallowing tablets, because they can cause a blockage in the throat if taken without enough water. You should not take glucomannan pills or powder if you have ever had esophageal narrowing. Glucomannan supplements in any form should never be taken without water as there is a danger you may choke if you attempt to take it dry.

If you suffer from diabetes and you are taking glucomannan, then you should monitor your blood sugar on a regular basis, as glucomannan may lower blood sugar levels. Taking glucomannan along with diabetes medications could make your blood sugar fall too low. Because of glucomannan’s effects on blood sugar, you should stop taking it at least two weeks before a scheduled surgery.

You should avoid taking glucomannan if you are pregnant or breastfeeding.

What to Look for in a Good Glucomannan Supplement

Glucomannan supplements are typically available as capsules or in a powdered form. Most contain between 1-2 grams of konjac root. Powdered glucomannan is often the best choice because it’s the purest form of konjac root and it is vegan-friendly and suitable for people with food sensitivities or allergies. You can easily add a powdered form of glucomannan to your food, drinks or shakes. You can even use it to make your own capsules.

If you are vegetarian or vegan, you will want to avoid capsules made from gelatin. Instead look for caps made from Hydroxypropylmethylcellulose (HPMC). These are made from synthetic substances, and they are vegan-friendly.

The best glucomannan supplements also do not include artificial sweeteners, colors, and preservatives. They do not contain unnecessary fillers such as magnesium stearate. You can easily see if a supplement contains fillers by looking at the listed inactive ingredients.
