Glucomannan – Uses In Weight-Loss Supplements & Side-Effects

Glucomannan is a very beneficial soluble dietary fiber taken out from the roots of Konjac plant. It it is used as an ingredient in various weight loss supplements including Phen24 as it helps in decreasing the cholesterol level in the body as well as aids in weight loss for people suffering from obesity.

People with diabetes have also noticed that it is very helpful in controlling their blood sugar level. It is also very effective in treating constipation and improve bowel movements.

Some studies have found that it can control our appetite and help us to stay lean. The products which contains Glucomannan as an ingredient comes either in the form of tablets or powder.

In some places it is also used for animals. The Japanese and Chinese people have been using supplements containing Glucomannan for a long time now as they believe it to be very safe as well as effective.

 Many of us may not know about soluble fibers. There are two types of dietary fibers which are soluble and insoluble fibers. Both of these fibers are usually found in most of the plants and each of them has a lot of benefits for our health.

Soluble fibers easily get dissolved in water whereas insoluble fibers don’t. These fibers contribute towards proper functioning of our body systems. Soluble fibers get dissolved in water and therefore, it has many digestion enhancing capabilities. 

On the other hand, insoluble attracts water which is very helpful in improving our bowel health. The root of Konjac plant is very rich in soluble fibers and thus, it has got a lot of health benefits for us.

I am going to discuss with you some of the important benefits derived from Glucomannan:

  1. Promotes Weight Loss

    Glucomannan gets dissolved in water and it has the ability to hold our appetite for a longer duration. People usually gain weight because of their strong desire to eat food frequently even if they are not actually hungry.

    Intake of oily snacks and heavy meal increases the level of fat stored in our body which contributes towards weight gains. But Glucomannan makes us feel full for a longer period of time and therefore, we can easily avoid eating heavier meal and snacks. This eventually helps in lowering the amount of fats stored in our body and thus, promotes weight loss.

  1. Lower Cholesterol Level

    When tested on people, it has been found that Glucomannan has ability to reduce the level of total cholesterol in our body. It is very useful for lowering the bad cholesterol level, thereby, storing more of the good cholesterol which is very helpful for the body as the good cholesterol transfers itself into the liver and the liver will convert it into usable energy.

    Whereas if the bad cholesterol level increases, it is more likely to cause heart disease and stroke. Thus, by lowering the bad cholesterol level Glucomannan helps us in having a healthy heart. However, its direct impact on increasing the good cholesterol level is still unknown and is under research.

  1. Control blood glucose

    Glucomannan is not only effective in lowering the bad cholesterol but it can also lower the level of blood glucose. It is very beneficial for people suffering from diabetes as they have higher level of blood glucose.

    This will help the people to control and balance a healthy blood sugar level and it is a well-known fact that having a healthy blood sugar level is essential not only for diabetes patients but for each and every one of us. It also enhances the tolerance capacity of blood glucose.

  1. Lower Blood Pressure Level

    Nowadays, due to irregular and unhealthy food habits many people has to face the problem of high blood pressure level. When the blood pressure level increases to an unhealthy level it can cause many health related issues like your blood vessels get damaged, breathe shortens and you may suffer from severe headache.

    But in the long run it causes heart problems. Glucomannan helps in reducing the blood pressure to a normal level, thereby, reducing the risk associated with high blood pressure.

  1. Improves bowel health

    As people gets older they it is usual to face problems like chronic constipation, adnominal pain, change in bowel habits, gastrointestinal diseases, inflammation, piles and many other problems. Not only in old people this may also happen to young people sometimes depending upon their food habits and daily routine.

    Consuming Glucomannan supplements have been found very effective in improving bowel movements and enhancing bowel health. Thus, it is very useful in preventing us from problems like constipation and gastrointestinal diseases and also helps in treating them.

  1. Aids Hyperthyroidism

    When the production of Thyroxine increases more than required, it stimulates the rate of metabolism abnormally. It causes our weight to reduce unintentionally and increases our heartbeat rate frequently which may lead to nervousness and restlessness. Higher heartbeat rate can also cause serious problems like heart failure.

    Some studies suggest that supplements containing Glucomannan and some other important ingredients help in reduce the higher amount of thyroxin.


So these were some of the main benefits that we can get from Glucomannan. Researchers are continuing their research and studies for gathering more evidence regarding these benefits. 

As this is a soluble fiber, therefore, it easily gets dissolved in water. Some researchers claim that not only the benefits mentioned above but Glucomannan also has the properties that could potentially cure breathing problems like asthma, skin infections and certain types of allergies.

Whether Glucomannan supplements contribute in weight loss or not is a matter of conflict among the people. Some say that they have found evidence that it is helpful for the overweight people as it contributed in fat loss. 

They have found that it can show its effectiveness just by consuming 4 grams of the supplements daily for a period of 8 to 12 weeks while others have been arguing the same. Again it happens to be one of the best choice for treatment of constipation and enhance the functioning of our digestive system.

It is normal to consume 30 grams of Glucomannan daily for this and even pregnant women and minors are unlikely have any harmful side effects when taken for a shorter duration. It is all good for adults to take up to 4 grams of Glucomannan supplements per day up to three months if you want to lower cholesterol level and for a minor maximum of 3 grams per day for two months is enough.

However, it is advisable that you should consult your doctor before taking these supplements because the dosage will depend on several factors of the person like their age, gender, health and also the reason they want to take these supplements and your doctor knows better about you and can prescribe you the appropriate dosage.

 It is very necessary to stick to normal dosage because like any other supplements made of either natural ingredients or artificial ingredients, excessive intake of Glucomannan supplements also has certain side effects and risks associated with it and you may have to face these negative consequences.

Side Effects And Risk Of Glucomannan

The following are some of the potential side effects and risk of Glucomannan supplements:

  1. Diarrhea

    Glucomannan improves the bowel movements. Excessive intake of Glucomannan can increase the bowel movements at an abnormal rate which may cause you diarrhea.
  1. Stomach Upset

    It controls our appetite for a longer duration. If you take it more than required regularly it can negatively affect the natural function of your body’s digestive system. It may cause you problems like heartburn and bitter taste, vomiting, flatulence, hiccups, etc.
  1. Lower Blood Glucose Level

    Glucomannan helps in lowering the blood glucose level from high to normal which is very effective for diabetes patients. But excessive intake of its supplement along with are anti-diabetes supplement may reduce the blood glucose into dangerous level which again is bad for health.

     So the duration and proper dosage by diabetes patients should be confirmed by a doctor before your start the cycle.

  1. Impacts Blood Sugar Control

    Regular consumption of Glucomannan may impact negatively on your body’s natural ability of blood glucose control. It may be very dangerous if you are undergoing any surgery and even during the post- surgery period. Therefore, it is recommended by health authorities its consumption should strictly be avoided at least 14 to 18 days before the date appointed for your surgery.
  1. Other Potential Side Effects

    Though Glucomannan is safe for pregnant women and breastfeeding mothers for shorter period of time, consuming it regularly for a longer duration of time may have negative effects on both the mother and their child.

So these were some of the potential side effects and risks associated with Glucomannan. Studies also say that it should be avoided consuming along with other medicines on the same because the benefits of the other medicines may potentially decrease. Therefore, there should a time gap of at least 60 to 90 minutes in between.
