Due to its swelling properties, glucomannan is often used as a food additive.

Benefits of taking glucomannan supplements

1) Glucomannan and Weight Loss

In a research review published in Alternative Therapies in Health and Medicine in 2005, scientists found that taking glucomannan in doses of two to four grams per day may result in significant weight loss among overweight and obese individuals. According to the review’s authors, glucomannan may help promote weight loss by increasing satiety (the feeling of fullness after eating).

While glucomannan shows promise as a weight loss aid, the review’s authors note that more research is needed to determine the safety and efficacy of taking glucomannan for weight loss.

2) Glucomannan and Cholesterol

Glucomannan may help keep cholesterol in check, suggests a 2008 report published in theAmerican Journal of Clinical Nutrition. After analyzing 14 clinical trials on glucomannan, the report’s authors concluded that glucomannan may lower total cholesterol and LDL (“bad”) cholesterol. In addition, glucomannan appeared to reduce body weight and cut levels of triglycerides (harmful blood fats). However, the report’s authors note that glucomannan does not seem to affect HDL (“good”) cholesterol or blood pressure.

3) Glucomannan and Constipation

Glucomannan may help treat childhood constipation, according to a 2004 study published inPediatrics. The study involved 46 chronically constipated children, each of whom was treated with either glucomannan or a placebo for four weeks. Among the 31 children who completed the study, researchers found that glucomannan was more effective in alleviating constipation. Glucomannan also appeared to reduce abdominal pain.

4) Glucomannan and Rheumatoid Arthritis

Glucomannan may help manage rheumatoid arthritis, according to preliminary research published in Neuro Endocrinology Letters. In tests on rats, the authors of a 2008 study found that certain antioxidants and anti-inflammatory compounds available in glucomannan may be beneficial in the treatment of rheumatoid arthritis.

Dosage for glucomannan

Glucomannan capsules and powders are available in single-serving doses as well as in bulk powder. Daily total doses of 3 to 4g of glucomannan, taken incrementally throughout the day before meals, are effective for weight loss.
