Glucomannan is a dietary fiber that dissolves in water and comes from the root of the konjac plant, or Amorphophallus konjac. As with most dietary fiber, glucomannan is an effective bulk-forming laxative, meaning that it stimulates the passing of larger, solider stool which can move through the colon smoothly and is easier to eject.
Early research and double-blind studies have demonstrated glucomannan’s efficacy in easing constipation. Constipated patients who take glucomannan can expect a bowel movement in as little as 12 hours. Studies have also indicated that glucomannan may be effective in treating diverticular disease of the colon. Glucomannan helped bout 30-50% of research subjects.
Glucomannan works in a similar way to other water-soluble fibers. It is able to attach itself to bile acids in the gastrointestinal system and move them out of the body in the form of excrement. This makes the body convert other cholesterol into bile acids, which can lower cholesterol and reduce the amount of other fats in the blood.
Glucomannan could be effective as a weight loss aid because it takes up space in the stomach, which then simulates the sensation of being full.

It has been asked by millions of people “If you eat a healthy diet, do you need to take vitamins?” Not very long ago, the common answer from most experts and professionals would have been an emphatic "no". However, today there's quite a bit of evidence that taking a daily multivitamin makes good sense for most adults.

Given the popularity and availability of “high potency” amino acids, antioxidants, enzymes and herbs, it might seem like dietary supplements could replace food as a source of the nutrients the body requires. However, this is not the case.
