What is the active ingredient TrimBall-EXP200?

According to one person who posted in Yahoo,

"haven't seen anything anywhere in my search that it causes problems for anyone. It is made from the root of the Konjac plant, and the Japanese make noodles and cakes out of it. The ingredient in Trimball-Exp200 is KGM-E425 (also known as Konjac glucomannan). The only thing is don't take more than recommended (since it works by absorbing stomach fluid and expanding) and you might want to look on the internet for for other companies that make diet capsules out of it because Trimball-Exp 200 looks quite expensive. Put "Konjac glucomannan capsules" into google. Several health food stores come up, as well as other companies you can buy it from off the internet.

I haven't tried it, but I wouldn't be afraid to.

If the main ingredient is indeed Konyac (a kind of glutinous greay root that has 0 cals and is used in Japan widely) then it is much cheaper and tastier to buy the stuff in blocks and eat it when you are hungry.
