What Is Glucomannan?

Glucomannan is a water-soluble dietary fiber taken from the roots of konjac plant, also known as elephant yam.

Supplement companies extract the glucomannan and supply it in the form of powders, often contained in easy-to-swallow capsules. It has a long history in Ayurvedic medicine, which is the natural, herbal medicine of the East.

If you’re familiar with Ayurvedic medicine, you’ve likely already encountered wonderful supplements like ashwagandha, rhodiola rosea, and bacopa monnieri. If you’re a fan of those, you will likely be a fan of konjac root extract too.

​Summary: ​​Glucomannan is a water-soluble dietary fiber taken from the roots of konjac plant, also known as elephant yam.

Is It Safe?​

It is considered safe but you should take a few precautions. Glucomannan is a water-soluble fiber that expands to up to 50 times its size when it comes into contact with water.

As such, there is a small risk of it expanding before it enters your stomach if you are not careful.

You really do not want it expanding in your throat because it can cause choking. You can prevent this from happening by ensuring that you take it with 1-2 glasses of water.

Does Glucomannan Work For Weight Loss?​

People of the East have used konjac root for weight loss for centuries. The reason for its use, and now the use of the extracted glucomannan, is due to its water-soluble nature.

Incredible Water-Absorbing Ability

Glucomannan has an incredible water-absorbing ability. Why is this good? Well, a water-soluble dietary fiber as strong as glucomannan makes you feel much fuller after eating less food than normal because it takes much of the space in your stomach.

Feel Fuller for Longer

If you feel fuller after one small meal, you’re going to eat less at the next meal and throughout the day. It also delays how fast your stomach can empty, which also makes you feel fuller for longer.

Reduces Fat and Protein Absorption

In addition to this, glucomannan also reduces fat and protein absorption and also improves the health of the good bacteria in your gut (1, 2).

​Studies have shown a correlation between weight loss and healthy gut bacteria (3).

It Works For Weight Loss

Glucomannan has been around for a while so there are plenty of scientific studies backing up its effectiveness.

Studies have consistently​ shown that regularly ingesting glucomannan ​before a meal improves weight loss more than not ingesting it (4, 5, 6).

It is particularly effective when paired with a weight loss diet, so it is important to ensure you are following one alongside using this.  It will really help to accelerate your fat loss.

One study looked at 176 overweight people who were on a calorie restricted diet.  They assigned half of participants to a placebo and the other half took glucomannan.  3 different glucomannan supplements were tested with varying dosages. 

After 5 weeks, weight loss among those who were​taking glucomannan was significantly greater than those who took the placebo (7).

In addition to the scientific studies, there is also plenty of anecdotal evidence and glucomannan weight loss reviews from happy customers who have lost weight using the supplement.

​Summary: ​When taken regularly before meals, glucomannan can lead to modest weight loss by instigating feelings of fullness and reducing calorie intake.  It is even more effective when paired with a weigth loss diet.​

Other Benefits of Glucomannan

Weight loss is glucomannan’s primary benefit. However, there are a few other reasons why one might wish to supplement their diet with it.

​A systemic review of 14 studies (8) showed that it can:

  • ​Lower total cholesterol and bad LDL cholesterol
  • Improve blood sugar levels
  • Lower risk of heart disease
  • Lower risk of Type 2 Diabetes

It has also been shown as a good treatment for constipation (​​9).

​Glucomannan Side Effects

Side effects include:

  • ​Bloating
  • Flatulence
  • Diarrhea

There is little cause of worry, however, because few people report these side effects.

Glucomannan Dosage​

Remember, just like with many supplements aimed at helping you with weight loss, your optimal glucomannan dosage will vary depending on your weight, age, health condition, and weight loss goals.

Read The Label

Make sure you read the label on your supplement and consult with a doctor if you have any concerns or health conditions. You should also start out with the lowest effective dose and build it up only if your body reacts positively.

Recommended Dosage: 1g Taken Before Meals​

The recommended dosage for weight loss is 1g taken before meals 3 times a day (​10). It’s very important that you take it before eating because otherwise it will not have any effect on weight loss.

Anywhere from 15 minutes to 1 hour before a meal should be sufficient.

​Summary: ​​The recommended dose is 1g taken 3 times per day with water.  Ideally you should take it 15min – 1 hour before eating.  Make sure you have it before your meal, as it will have no effect otherwise.

Pros Of Glucomannan​

  • It’s cheap.
  • There are many glucomannan reviews raving about how great the supplement is and how much it has helped them with weight loss.
  • In addition to the appetite suppressing effects, it’s good to have a product that will help keep your cholesterol and blood sugar levels in check.

Cons Of Glucomannan​

  • While it may work for many people, there are also many people that report it not working. Of course, you must ensure that you follow a proper diet and exercise routine for weight loss but, even then, some reviews have reported glucomannan to be ineffective.
  • It might take some experimentation with different glucomannan brands before you find the one that is right for you.

This brand certainly isn’t for everybody but it’s definitely high quality.

It’s not for everybody because it comes in a powder form rather than in capsules.

It’s also about double the price of the other supplements but you get a pound of powder. I sometimes prefer the raw powder rather than swallowing down more capsules or pills.

I already take a bunch of capsules so it’s good to give my esophagus a rest. I like to mix it in smoothies or yogurt.

PROS – ​2000mg and quality product that is made in the USA and cGMP certified.

CONS – ​Some customers found it not to be as effective as they would have liked.

​Should You Try It?

Looking at the evience, glucomannan is a great addition to the supplement stack of almost anyone looking to lose weight. But, as I always say, this supplement is not going to do the heavy lifting for you.

You still need to make sure that you are following a weight loss diet and exercising regularly.  ​This will ensure you get the most out of supplementing ​too.

However, iIt really will help to make you feel more full so that should make it much easier for you to moderate how much food you eat. It’s up to you from there!
