Glucomannan is commonly used as a food additive for its thickening properties and as a
supplement for weight loss, blood sugar control, and cholesterol management.
Key Properties:
Water Absorption: Glucomannan can absorb up to 50 times its weight in water, making it
highly effective at creating a feeling of fullness.
Low Calorie: It is very low in calories, which makes it popular in low-calorie and weight-loss
diets.
Digestive Health: As a fiber, it helps promote bowel regularity and is often used to treat
constipation.
Cholesterol and Blood Sugar Control: It may help lower cholesterol levels and slow the
absorption of sugar, which can benefit people with diabetes.
Food Industry: In the food industry, it’s used as a thickener in products like noodles (shirataki
noodles), tofu, and as a gelling agent in desserts.
If you're considering using glucomannan, it's important to drink plenty of water with it to
avoid the risk of choking or intestinal blockage, as it expands in the digestive tract.
Glucomannan can be purchased at various locations, including:
Health Food Stores: Many health food stores or specialty grocery stores carry glucomannan in powder, capsule, or supplement form.
Pharmacies: Some large chain pharmacies may stock glucomannan supplements in the dietary supplement section.
Online Retailers: Websites like Amazon, iHerb, and Vitacost offer a variety of glucomannan
products, including powders, capsules, and shirataki noodles.
Supermarkets: Some larger supermarkets, especially those with a focus on health foods, may
carry glucomannan products, particularly shirataki noodles.
Asian Markets: Since glucomannan is derived from konjac, it is commonly used in Asian cuisine.
You can find glucomannan products like konjac jelly or shirataki noodles at Asian grocery stores.
When purchasing glucomannan, it's important to read the product label to ensure you're
getting a pure product, especially if you're looking for it as a dietary supplement.
