The number of products is so high that it is often daunting for any potential customer to differentiate between the real and the fake. Each supplement claims to be the best, and thus it is natural for you to get confused.
Amidst this, there is a weight loss supplement that has been grabbing eyeballs. It is the Glucomannan weight loss supplement. Here, we would take a candid and honest look at this weight loss supplement.
A natural dietary fiber, Glucomannan is extracted from the roots of the konjac plant, popularly known as elephant yam. 40 percent of this root is made of Glucomannan.
The plant is native to Southeast Asia. Studies show that Glucomannan powder has been used for centuries by the people of these regions both as food and in traditional medicines to cure many diseases.
The famous healthy Japanese Shirataki noodles are made from Glucomannan. In food, Glucomannan flour and powder is used in various recipes as a thickener or gelling agent.
Medically, it was used to cure many diseases like constipation, diabetes, hyperthyroidism, high blood pressure, high cholesterol levels, stomach conditions like dumping syndrome and various other gastrointestinal disorders.
The standout feature of Glucomannan is its extraordinary ability to absorb water. It can absorb more than 50 times its weight of water and transform in jelly.
One can easily ascertain this by adding the contents of the Glucomannan capsule in a glass of water and mix it well. The water will take a gel-like consistency or even turn into a paste.
It is this incredible absorption capacity and viscosity of Glucomannan that is attributed to be the key to its effectivity in promoting wellness and weight loss. This product is available as capsules, powder, and tablets.
Ingredients of Glucomannan supplement
Each capsule of the Glucomannan supplement has about 1.725 gm of Glucomannan. Apart from it, it has other non-active ingredients like the cellulose, silica and magnesium stearate.
All these are extracted from the vegetable source. Finally, the powder is encapsulated in a bovine gelatin capsule. Thus, the supplement is completely vegan and can be easily used by all.
How does Glucomannan work?
It works in the stomach and the intestine by absorbing water and forming a bulky fiber. As this fiber cannot be digested by the body, it has no caloric value attached to it.
This viscous gel-like fiber works on three mechanisms which help you suppress your appetite and help you lose weight. The three mechanisms are:
- Mechanical- The fiber absorbs water and becomes bulky and occupies quite a lot of space in the gut. Consequently, your stomach feels full and satiated and you eat less.
- Hormonal– The fiber also impacts your appetite hormones to reduce your hunger pangs and keep you satiated for a longer
- Transition Time- As the fiber occupies a room in your gut, it slows down the process of absorption of food in the intestine and thus helps you reduce your food intake.
There are various properties of Glucomannan via which it helps you lose weight. The leading properties of the supplement are:
- A natural probiotics
Probiotics are substances that help restore the balance of the good and the harmful bacteria in the gut. Probiotics are substances that act as precursors to probiotics. They cannot be digested by our bodies as such, but the good bacteria present in our gut can easily digest them.
Consequently, they serve as food to these good bacteria and help in their multiplication. Glucomannan passes undigested from upper gastrointestinal tract and reaches the colon where the good bacteria are present.
The good bacteria ferment them to create probiotics. As this gut microflora grows, it shows many health benefits including the strengthening of the immunity system and eventually helps you lose weight.
- Helps in relieving constipation
Glucomannan is a natural laxative. By absorbing plenty of water, it promotes the formation of larger and bulkier stool which is able to pass through the colon in a more effortless manner.
The action is also quite fast since all other bulk-forming laxatives available in the market typically take about twelve to fourteen hours after intake to encourage the bowel movement.
- Helps in managing the cholesterol level
Various studies were conducted on Glucomannan which indicated that it had plenty of beneficial effect on the total cholesterol level of the body. Surprisingly, it does not impact the blood pressure and high-density lipoprotein or the ‘good cholesterol’ in any manner.
However, it helps reduce the level of low-density lipoprotein or ‘bad’ cholesterol as well as the harmful blood fats called triglycerides.
When the Glucomannan fiber expands in the gut, it slows down as well as decrease the absorption of the bad cholesterol which is then flushed out of the body via stool. Thus, it comes across as a natural and drug-free way to reduce the cholesterol level in the body.
- Helps in controlling blood sugar levels
Various scientific studies have been conducted to show the effect of Glucomannan on diabetes. Foremost, it slows down the stomach’s emptying process.
Due to this, the sugar absorption process slows down and becomes more gradual. Thus, you show lower blood sugar levels after meals. However, one needs to be cautious and keep monitoring the blood sugar levels especially if one is on blood sugar lowering drug.
Glucomannan and weight loss

Done right and in a proper manner, it accelerates your pace of weight loss and leaves you leaner and healthier. It may not show an appreciable weight loss if no change is made to your diet or sufficient exercise is not supporting it.
According to a study, when combined with psyllium husk and given to participants, Glucomannan helped reduce about 10 pounds over a span of 16 groups. For comparison, a placebo group was created as well which lost just 1.6 pounds in the same time span.
