What Is Glucomannan?

Glucomannan is a dietary fiber used as a standalone supplement or a supplement additive. It is extracted from konjac root; konjac is a well-known and beloved plant in Asia. Konjac root has been used for centuries to treat illness and supplement overall health.

Further, glucomannan pills have proven benefits in both metabolisms- and digestion-related health concerns. This dietary fiber is beneficial for women who frequently suffer from weight gain, dysmenorrhea, high blood sugar, and hemorrhoids.

Konjac root also helps lower blood sugar levels and promotes easier maintenance of blood glucose levels. The best glucomannan supplement, according to us, is that which offers other health benefits as well as weight loss help.

A glucomannan fiber supplement might be the perfect weight-loss aid for individuals interested in slimming down naturally.

In the supplements we have chosen for your consideration today, glucomannan acts in aid of weight loss primarily by emulating a "full" feeling and curbing appetite. Not to mention, glucomannan, as a water-soluble dietary fiber itself, contains very few calories.

Derived from the root of the konjac plant, glucomannan is a dietary fiber whose benefits have been tracked in several independent studies. With its key benefits being the promotion of weight loss and the ability to lower cholesterol levels, this konjac root fiber has been growing in popularity among weight loss enthusiasts.

1. PhenQ- Best Weight Loss Pill Overall, Losing More Than 30 Pounds

Are you looking to lose a large amount of weight in a short time? If you combine a healthy diet with a rigorous workout routine, you might just get there. But for those of you who need a little push, PhenQ is here to save the day.

Why do so many people recommend PhenQ? That's easy. Besides burning fat, this weight-loss dietary supplement works primarily by suppressing appetite, where glucomannan comes in. Once ingested, glucomannan swells in the digestive tract, which causes the user to feel fuller and thereby reduces their appetite.

But arguably, one of our favorite things about PhenQ is that it also boosts energy and mood, which it does with the help of active ingredients such as nopal and caffeine.

The best part? PhenQ is not only wholly backed by clinical trials but these dietary supplements are manufactured in FDA- and GMP-approved facilities. And, because one bottle of PhenQ contains 60 pills, you can easily expect it to last you for an entire month.

What to Expect

  • Facilitates a more manageable weight loss journey by suppressing appetite
  • Boosts mood and energy
  • Allows for quicker weight loss
  • Clinically proven
  • It comes with a 60-day money-back guarantee

How It Works

PhenQ stands out primarily thanks to the proprietary formula α-LACYS Reset®. α-Lacys Reset® promotes healthy metabolism rates by activating your body's thermogenesis and allows you to burn fat more quickly. So, all of that stubborn fat that just refuses to leave your body is directly targeted by PhenQ.

Meanwhile, the nopal cactus in PhenQ enriches the supplement with amino acids and fiber. Furthermore, Chromium picolinate specifically targets cravings for carbs and sugar. And working with glucomannan to keep you feeling full in between meals so you don't feel the urge to start snacking.

PhenQ Ingredients

  • α-LACYS Reset®
  • Capsicum
  • Piperine
  • Niacin

Who PhenQ Is for?

Not everyone responds in the same way to a weight loss journey. For some of us, the process is much more complicated than for others. Whether it's because you have a significant amount of body fat or because your metabolism is lower, PhenQ can be the answer to your problems.

It allows you to shed a larger amount of fat in a short time and keeps you feeling energized and motivated throughout your weight loss journey.

However, it's important to note that breastfeeding and pregnant women, and women under 18 years of age, should avoid taking PhenQ.

Meanwhile, the glucomannan component in konjac root keeps you feeling full, so you don't overeat or give in to snacking temptations. Meanwhile, the grains of paradise burn brown adipose tissue, which usually produces body heat in extreme situations.

4. Phen24 - Best Weight Loss Pill for Combining with Diet

One of the essential components of any effective weight loss plan is a healthy diet.

What makes Phen24 stand out to us, though, is that it is a weight loss pill that is suitable for the needs of both women and men.

What to Expect

This works by giving your body's metabolism time to compensate for the constant fat breakdown that occurs due to the consumption of Phen24.

Once your diet is through, it's recommended to take another break before taking on another short-term diet consisting of healthy components. This will help your body to align with the results of being used to a lower number of calories. After that, your metabolism slowly increases again, which allows for a smoother weight loss process.

Many users of Phen24 also report feeling an increase in energy and strength, which further allows for a smoother weight loss plan that takes less time to show results. The success of Phen24 to many who take it can be attributed to its composition of potent and natural herbal ingredients.

Glucomannan Supplement Buying Guide

Before going out to buy your own set of Glucomannan Supplements for weight loss, there are a few considerations you need to take into account.


We find that the best glucomannan supplements contain entirely natural ingredients. This is the safest option to go for. You'll typically find glucomannan combined in a supplement with caffeine, green coffee, acai berry, seeds of paradise, etc.

Such natural ingredients usually provide myriad health benefits besides promoting weight reduction in tandem with glucomannan.

Before you are taken in by all the benefits of glucomannan and other nutrients present in the supplement, try to ensure that it will suit your body. However, as with any ingredient, too much of a good thing can be harmful, such as caffeine.

For this reason, it's recommended to also check the suggested dosage alongside the full roster of ingredients before confirming a glucomannan supplement.

Supplement Form

Glucomannan products come in different forms, such as capsules, tablets, powder, and gummies. How you're able to incorporate the supplement depends on the form you choose.

The powdered form's most popular option and a close second are capsules. These are very versatile and can be used with almost any meal. Whether you want to add Glucomannan to your pasta or your shake, the powder will blend in with everything.

Tablets and gummies are also good options, but they can be choking hazards if not taken carefully. The supplements tend to expand quickly, so you must always flush them down with plenty of water.

Health Status

Before indulging in any form of supplement regularly, you must always consult your nutritionist or physician. Not everyone's body is the same, and so, to ensure safe use, a thorough check needs to be done.

Fiber supplements tend to cause problems in some people while others seem unaffected. If you're taking other medications, you also need to ensure your supplements aren't conflicting with them.

We would not recommend Glucomannan supplements to women who are pregnant. During pregnancy, fiber absorption is essential for the mother and the baby. The supplements will increase the chances of pregnancy constipation and hemorrhoids, which can be very painful.


It is generally believed that pregnant women should avoid consuming too much fiber. Excessive fiber may lead an expecting mother to experience constipation and flatulence. Long-term constipation issues might cause the formation of hemorrhoids, which can be extremely painful during and after childbirth.

All of this considered, most scrupulous manufacturers of supplements containing glucomannan warn against pregnant women's consumption of their pills. However, studies have shown that the effects of glucomannan fiber on expecting mothers are different.

Most pregnant women who took glucomannan experienced six times as much bowel movement as a fourth of women who faced over six times the bowel movement.

All of this to say, glucomannan has also been used to treat constipation faced by expecting mothers. Still, if you are pregnant, consult with a doctor before using glucomannan to treat constipation.

Vegan Or Not

Glucomannan itself originates in Konjac root, but that does not make every Glucomannan supplement safe for vegans. While most ingredients are taken from natural sources, some supplements might contain gelatin.

It is always a good practice to read the label to identify any ingredients that might not be suitable for your eating habits. Vegan Glucomannan supplements are widely-available, so you won't have to scour the internet to get them.

Side Effects

The effects of glucomannan are typically seen to be relatively safe for most adults. There might be some extreme cases where consuming glucomannan might cause undesirable side effects such as flatulence, bloating, diarrhea, and the presence of soft stools.

All that said, these adverse side effects of glucomannan are thought to be quite rare. Still, if you have pre-existing digestive issues, we suggest cautiously approaching your new glucomannan supplement.


After considering all the health aspects, your budget comes down. Investing in Glucomannan supplements isn't a one-time thing. You will need to continue regular doses for months to get the best results. It should take about a month or two to achieve controlled blood sugar, blood pressure, and cholesterol levels.

Set aside your budget and make a monthly plan to find an effective and affordable supplement.

Frequently Asked Questions

1. Is glucomannan naturally made?

Yes, glucomannan tablets are made entirely from the roots of a konjac plant. This creates a fiber that can be used as a supplement alone or as an additive. As you may know, fiber is an essential part of the human diet.

2. How do glucomannan supplements help?

Glucomannan supplements are made from entirely natural materials. It helps detoxify your body and reduce the chances of diabetes and constipation. It increases the time for the sugar to be absorbed by your body, promoting healthy cholesterol levels in check and allowing for healthy weight management.

Since the supplements are water-soluble, they can make you believe you're full by absorbing water in the gut. This can speed up any weight loss plan and might even reduce blood pressure in the long run.

3. What does glucomannan do in the body?

Like all soluble fibers, glucomannan is a highly absorbent ingredient, forming a gel when it binds with water. Studies of glucomannan have shown that glucomannan, when ingested, absorbs water and draws it into the stomach.

As glucomannan expands in the stomach, this bulky fiber makes you feel fuller. It treats constipation by hastening the process of food digestion in the colon.

Furthermore, glucomannan root also absorbs cholesterol and sugar from the gut. In this way, taking glucomannan might help control sugar levels and help with controlling diabetes. This is why glucomannan is also suggested for obese individuals.

For all of the above reasons, glucomannan is seen as an effective supplement for appetite suppression and creating a feeling of fullness by delaying the process of bowel emptying.

4. Are there any side effects to using glucomannan supplements?

On the whole, Glucomannan supplements have no severe side effects and are believed to be safe for adults. However, doses should be taken as prescribed over a short time if you want benefits other than aid weight loss.

There are instances where people have diarrhea or an upset stomach taking glucomannan, but these are pretty rare. Since the supplements dissolve fast, they can expand before hitting your stomach. Always have it with water or other liquid to prevent yourself from choking.

5. How much glucomannan should I take?

Based on research, the standardized glucomannan supplement dosage is 1g taken a day thrice for weight management and other health benefits.

In whichever form (capsules, powder, or tablets) you take, ensure that it is less than 4 grams of glucomannan per day. This should help boost your weight loss progress, especially alongside a calorie-restricted diet.

For people just starting, start with a lower glucomannan dosage than what you've been recommended to help your body adjust. Once your body has gotten used to the supplements, you can increase your dose.

The general rule is to take glucomannan pills with a good amount of water around 15 minutes to 30 minutes before your next meal (but not longer than an hour). This will help the supplement travel safely to your stomach without expanding mid-way.

6. Is glucomannan suitable for a keto diet?

Glucomannan supplements complement ketogenic diets because they act as catalysts to the weight loss process. Adding these supplements to your diet will increase the amount of cholesterol expelled by your body. As a result, healthy cholesterol levels are ensured. So, taking glucomannan root along with a keto diet is suitable.

7. How long should I take glucomannan?

A safe duration would be around four months for people consuming Glucomannan capsules or powdered glucomannan. We would advise against solid tablets as they can lead to choking.

Final Words

The evidence for glucomannan shows us that it can support weight loss. Furthermore, it can help deal with constipation, fight diabetes and obesity by lowering blood sugar, and even reduce harmful LDL cholesterol levels.

But suppose you're using glucomannan as a weight loss supplement. In that case, however, it's important to note that simply taking the supplements alone will not cause you to lose weight. For that, you must have an effective workout and diet regime in place as well.

And that's it! We hope that our reviews of the best glucomannan pills have helped you find the best glucomannan supplements for you. We wish you good luck with your weight loss plan.
