Glucomannan is a soluble, bulk-forming fiber derived from Konjac Root (Amorphophallus konjac). 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. 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.

Suggested Use

As a dietary supplement, take 1/2 level teaspoon (2 g) daily with at least 8 oz of water 30 - 45 minutes before a meal.

good for in shakes

Posted by iHerb Customer on Aug 09, 2017 | Verified Purchase

This powder is good for shakes for the rest, the capsules are better. Maybe iHerb can offer a combination.

Thanks for your feedback!

The powder works and results are visible in my case after some weeks. Next time I will try the capsules instead because they are easier to ingest but overall the sense of hunger is calmed for some hours. All in all I'm satisfied

Thanks for your feedback!

Better than psyllium husks

Posted by iHerb Customer on Jun 21, 2017 | Verified Purchase

One month ago I switched from using psyllium husks as my source of water soluble fibre, to using this powdered konjac root (Glucomannan). Very hard to find in the powdered form. Much easier to drink when mixed with water (compared to psyllium husks) and more pleasant. Weight has continued to drop while eating same diet and I feel great. We have dabbled in other uses as well. Thickens up watery dishes well and fun to add to milk etc. My wife is Japanese and misses some Japanese foods such as konyakku noodles, so we may try making konjac noodles with it.

Thanks for your feedback!

I owe a significant share of my success to Glucomannan. I strongly recommend this product!

I've been using this soluble fiber supplement for a little over one months now and through it, have been able to lower my A1c and lipids/cholesterol/ triglycerides. It's totally tasteless and isn't gritty. I put the suggested dose, 1/2 teaspoon, in my low-fat smoothie every morning. I've lost 7kg using it over a 20 day period. t still controls my hunger and helps fiber wise with any eating habits.There are a ton of articles and medical abstracts about this special Konjac root fiber, just search it's name. I also reduced my lipids almost by half and I did it all without ANY drugs or scrips !! I owe a significant share of my success to Glucomannan. I strongly recommend this product!
