Frequently Asked Questions About Glucomannan
Q: What Is Glucomannan?
Glucomannan is a natural, water-soluble dietary fiber usually made from the root of the konjac plant, also known as devil’s tongue, voodoo lily, elephant yam, or snake palm.
Approximately 40% of the plant’s dry weight is made up of glucomannan, and it’s available as a dietary supplement or food additive.
It can also be added to foods like pasta and flour to serve as a natural thickening agent and emulsifier and is believed to offer a variety of health benefits.
Q: What Are The Benefits of Glucomannan?
Glucomannan is traditionally used in Asian cultures to detoxify and reduce asthma symptoms, constipation, high cholesterol, and diabetes.
Due to its exceptional ability to absorb water (approximately 50 times its weight), glucomannan is believed to aid in weight loss as it helps promote a feeling of fullness and reduce appetite.
This can also help slow the absorption of sugar and cholesterol in the gut, which helps reduce cholesterol levels overall.
Glucomannan is also believed to fight certain types of cancer and slow down the aging process, although these claims are not backed by much evidence.
Q: Does Glucomannan Have Any Side Effects?
Overall, glucomannan is well-tolerated and generally considered safe for most adults to consume when taken as prescribed and for a short period.
However, some people may experience bloating, flatulence, stomach upset, and diarrhea, but these are uncommon.
As glucomannan could expand before reaching the stomach, it should always be taken with water or another liquid to prevent choking.
Even though glucomannan supplements are presumed safe to use, it’s always best to speak with your doctor first and check whether it’s safe to use alongside any medications and pre-existing conditions.
Q: How Do I Take Glucomannan Supplements?
Powder, capsules, and tablets are the most common forms of glucomannan supplements, with powder being the most popular.
There is no standardized glucomannan supplement dosage at the time of writing as the FDA does not regulate it.
However, depending on your reasons for taking glucomannan, a standard dose of 1 to 4 grams a day is generally considered sufficient to support weight loss.
If you’re taking glucomannan to ease constipation, most manufacturers recommend between 2 to 4.5 grams per day.
If this is your first time taking glucomannan, then you should start with half of the manufacturer’s recommend serving until you’ve assessed your tolerance.
Glucomannan should be taken with plenty of water to avoid it expanding before reaching your stomach and anywhere from 15 minutes to an hour before a meal.
Do not take glucomannan if you are pregnant or breastfeeding.
Q: Which Glucomannan Supplement Should I Choose?
To ensure quality and safety, you should choose a glucomannan supplement that’s been tested and verified by an independent third party, and that’s free from as many artificial ingredients as possible.
The type of supplements you choose essentially boils down to preference.
However, powdered glucomannan can easily be added to various meals, drinks, or shakes, which makes it super convenient and a preferred choice, in our opinion.
Also, make sure that the brand you choose lists all the individual ingredients, instead of a proprietary blend, on the Supplement Facts label, so you know exactly what you’re getting.
