Glucomannan Supplements Guide

Even with a healthy diet and exercise routine, losing weight and permanently sustaining the weight loss can be a challenge. There are many weight loss supplements on the market that make grandiose promises but do not fulfill them in the long-run.

Glucomannan is also referred to as Glucomannano or Glucomannane. It is a dietary fiber that has been made from the root of a Konjac plant.

This plant is a Japanese root vegetable made of fiber and water; its root is mostly ground into powder. The Glucomannan supplements are used as medicine and come in forms of powder, capsules, and tablets.

What Are Glucomannan Supplements?

Glucomannan is a naturally-occurring dietary fiber that is frequently used as a weight loss supplement. It is extracted from the konjac plant (otherwise known as Amorphophallus konjac). People in East Asia have been using Glucomannan powder for several thousand years.

It is a highly water-soluble dietary fiber that is taken from the roots of the elephant yam plant and is used as a dietary supplement since it is so low in calories and high in fiber. Glucomannan supplements are now being sold online and in stores and pharmacies.

Glucomannan can be used orally, or you can put the supplements in food. According to this medical article when ingesting Glucomannan orally, it can be used for weight loss, diabetes, constipation, high cholesterol, high blood pressure, dumping syndrome which is a stomach condition, and hyperthyroidism.

The Glucomannan powder form and flour can be used in foods for consumption. The supplement is added to food; it’s used to thicken it.

Proposed Uses of Glucomannan


Did you know that consuming less fiber can lead to your body fighting back, that is through constipation? Glucomannan root ingredient is made from fiber and water. Meaning this supplement is considered to be a natural laxative.

High cholesterol

An analysis of the Glucomannan supplements showed that this supplement had potential beneficial effects on the total amount of cholesterol, the bad cholesterol, triglycerides.

Overactive thyroid

Hyperthyroidism refers to the overactive thyroid. Researchers have discovered that Glucomannan combined with methimazole and propranolol have shown they help in reducing thyroid hormone levels in people with hyperthyroidism in the body.


Some researchers have shown that when taking this supplement orally can help with weight loss. Glucomannan weight loss is possible but only if you lead a generally healthy lifestyle by eating clean and avoiding fattening foods, like fast foods. Konjac’s fiber is ideal because it has a very low-calorie count and it is very high in fiber. After the consumption of konjac powder, it promotes the feeling of being full, and thus, makes the chances of overeating less.


Glucomannan supplements seem to be possibly safe for most adults to take as powder or capsules when they are consumed with a meal. Some adults should beware of solid Glucomannan tablets, as these supplements are known to cause intestinal or throat blockages.

As of right now, there is no research to indicate whether or not Glucomannan supplements are safe for women who are pregnant, trying to become pregnant, or who are breastfeeding. It is best to err on the side of caution and avoid taking these supplements in these cases.

Glucomannan supplements might also interfere with blood sugar control, so diabetics need to carefully monitor their usage of Glucommanan and keep a close eye on their blood sugar levels.

Also, Glucomannan supplements can possibly interfere with blood sugar control during and after surgical procedures. If you are scheduled to undergo surgery, you should stop taking your Glucomannan supplements about two weeks in advance and resume them when your doctor indicates that it is safe to do so.

Always speak with a medical professional or doctor before taking any supplements. Always read the product label for instructions and directions.

Taking Glucomannan Supplements

As with any supplement, you should always consult with your doctor before taking Glucomannan supplements. Doctors can give you their recommendations for brands and dosages, and it is important to always follow recommended dosages.

Generally, Glucomannan supplements are taken orally in capsule or powder form.

You should take these supplements somewhere between 15 minutes and an hour before a meal. Always follow the dosage recommendation from your doctor or from the manufacturing brand you purchase. Doubling-up could potentially lead to unpleasant side effects, such as constipation.

The dosage for adults by mouth differs depending on the ailment. The Glucomannan dosage typically ranges from 2-4.5 grams every day but divided into small doses. The dosage can be used for up to 12 weeks.

The dosage for the children by mouth is a 100 milligram per kilogram and can be taken for up to 12 weeks as well. The doses of 1 gram of this supplement can be taken two times daily for eight weeks for the children that are under six years.

What to Look for in a Good Glucomannan Supplement

Glucomannan can be bought in noodle form (as shirataki noodles), but it seems to be best in capsule or powder form. Some brands sell capsules that contain between 1,000 and 2,000 mg of konjac root.

Powdered Glucomannan is sometimes the best choice since it can come in a totally pure konjac root formula. This is especially optional for vegans, vegetarians, and those with food allergies or sensitivities since powdered konjac root is naturally vegan. Powdered formulas can easily be added to foods and drinks.

It is a good rule of thumb to avoid gelatin capsules if you are vegan or vegetarian; instead, look for capsules made from hydroxyproyl methylcellulose (HPMC), which is a synthetic and vegan-friendly product.

Another reason to try powdered Glucomannan is that you can avoid additives, fillers, and dyes that tend to be used to manufacture capsules. These will generally be listed as inactive ingredients, but research is starting to show that these ingredients can be harmful to some people.

Glucomannan supplements are certainly gaining popularity and reputability and they work best when taken as part of a healthy daily dietary and exercise regimen.

If you are thinking about taking Glucomannan supplements, you should speak with your doctor to find out if these well-regarded weight loss supplements might be right for you. They will not give you an overnight miracle.
