How to avoid Glucomannan supplement side effect

Is there any potential Glucomannan supplement side effect? The reviews will show the answer of taking glucomannan supplement.

In recent decades, glucomannan has been introduced to the United States and European markets as a food additive and dietary supplement. What is glucomannan? It is a beneficial, soluble and fermentable dietary fiber derived from the root of the konjac plant, which is native to Asia.

Fast-forward to present day and scientific studies have revealed that supplementing with konjac glucomannan can significantly lower plasma cholesterol, improve carbohydrate metabolism, encourage bowel movements and promote a healthy colon.

Does it really work?

Studying mechanisms is always interesting, but what we really want to know is if this stuff leads to actual pounds being lost.

Fortunately, we have several randomized controlled trials on glucomannan. These types of studies are the gold standard of scientific experimentation in humans.

In the biggest one, 176 healthy overweight people were randomly assigned to ingest either a supplement with glucomannan or placebo (a dummy pill), while on a calorie-restricted diet


Glucomannan has been investigated for its effects on weight reduction, diabetes, constipation, cholesterol, lung cancer, and atopic diseases, as well as its use as a prebiotic. However, there is a lack of adequately sized quality clinical trials to support these uses.

Special precautions and warnings

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking glucomannan if you are pregnant or breastfeeding. Stay on the safe side and avoid use.

Diabetes: Glucomannan may interfere with blood sugar control. Monitor blood sugar closely if you have diabetes and use glucomannan.

Surgery: Glucomannan might interfere with blood sugar control during and after surgery. Stop using glucomannan at least 2 weeks before a scheduled surgery.

Possible side effects

Glucomannan, like other types of soluble fiber, can cause gastrointestinal side effects when you suddenly increase the amount you consume. These can include bloating, stomach pains, loose stools, flatulence, and diarrhea. While diarrhea can be a side effect, this does not mean glucomannan is effective for treating constipation. A study published in Clinical Nutrition in August 2011 found that glucomannan was not beneficial for treating functional constipation in children.
