konjac fiber supplement glucomannan root benefits healthy
What is glucomannan/konjac?
Glucomannan, or konjac as it is sometimes known, is a natural, water-soluble fibre derived from the roots of a south-east Asian plant called the elephant yam.
It has been traditionally used by the Chinese to detoxify and ease symptoms of asthma, and is still used to make noodles and tofu.
It is often used as a bulking agent in foods, appearing as E425 on food labels. It’s also available as capsules and powder, and is added to some diet foods such as pastas and noodles.
What does glucomannan do in the body?
As with any fibre, glucomannan can help you feel more satisfied after eating, but what makes it interesting to scientists is that glucomannan has extraordinary water absorption capacities – it’s able to absorb up to 50 times its own weight in water!
Summary
- Glucomannan is a natural fibre sourced from elephant yam roots
- It’s used to bulk up foods and is also a popular ingredient in diet foods like noodles and pasta
- It can absorb 50x its own weight in water in your stomach – which is why it can help you feel fuller for longer

5 benefits of glucomannan
Now you know what glucomannan is, here are the top 5 potential glucomannan benefits.
It may help you maintain your weight
Like all soluble fibres, glucomannan is highly absorbent, binding to water to form a gel. This helps:
- Create a sensation of fullness that can reduce appetite
- Delay stomach emptying, keeping you feeling fuller for longer
- Break down carbohydrates more slowly, stabilising post-meal blood sugar levels
- Decrease fat absorption
A 2005 study by Norway’s University of Tromso reported that dieters who took glucomannan lost more weight than those taking other high-fibre supplements.
However, a 2013 study in Journal of Obesity found it had no effect on weight.
It may support gut health
As a viscous dietary fibre, glucomannan is the favourite food for certain friendly bacteria in our guts.
A 2010 laboratory study by the University of Reading found that it helped encourage healthy levels of gut bacteria populations, for example bifidobacterium, but more research on humans is still needed.
And like all fibres, glucomannan can reduce constipation by increasing bulk, and speeding up food transit time through the colon.
It can lower cholesterol levels
According to a 2008 review of evidence in The American Journal of Clinical Nutrition, glucomannan can reduce levels of total cholesterol and cause a drop in ‘bad’ LDL cholesterol, too.
Researchers suggested that glucomannan has this effect by altering both the way cholesterol is produced in the liver and how fats in the body are stored or used for energy.
It could help relieve constipation
Consuming glucomannan when you’re feeling constipated could help to ‘get things moving’ in your gut and help you find relief.
This is thought to be because more fibre in general will help relieve constipation – and glucomannan is an excellent source of that!
One study on 31 children found that supplementing glucomannan was beneficial for treating chronic constipation with no significant side effects. Significantly fewer children complained of abdominal pain, too.
Another study with pregnant women suggested that supplementing glucomannan could help improve their constipation symptoms. The participants reported that taking glucomannan improved consistency and frequency of stools.
It could support healthy skin
Glucomannan could help to keep your skin hydrated and healthy.
This is thought to be because glucomannan is a natural probiotic that can act as fuel for our skin’s microbiome and help keep it balanced.
There is limited research on its efficacy, but one 2013 study found that glucomannan may help to improve overall skin health, as well as potentially helping to soothe acne symptoms.
Summary
- Glucomannan is not just a supplement to help you maintain your weight, people also use it to support their gut health, cholesterol levels, healthy skin, as well as constipation relief
