Glucomannan is a soluble, bulk-forming fiber derived from the konjac root (Amorphophallus konjac).&ampnbsp; Clinical studies have demonstrated that Glucomannan can provide temporary relief of constipation and may help to maintain serum lipid levels already within the healthy range.&ampnbsp; In addition, because Glucomannan helps to promote satiety (feeling of fullness), it can be an effective addition to a weight management plan that includes a healthy diet and exercise program.*
