Glucomannan
Glucomannan is a soluble plant-derived dietary fiber obtained from the tubers of the konjac plant (Amorphophallus konjac). When it comes into contact with water, it absorbs a large amount of liquid, swells, and forms a thick, gel-like mass.

Natural sources of glucomannan
Glucomannan is naturally obtained from the tubers of the konjac plant (Amorphophallus konjac), which contain large amounts of this soluble fiber. In supplements, it comes in capsule or powder form.
Recommended glucomannan dosage
Around 2-4 g of glucomannan per day is typically used, divided into several doses and each taken with plenty of water. The exact dose should be chosen individually, based on diet, tolerance, and the specific product's usage instructions.
Possible side effects of glucomannan and interactions with medications
Glucomannan is generally well tolerated, but larger amounts may cause bloating, gas, abdominal discomfort, or diarrhea. Because of its ability to form a gel in the intestine, it may slow the absorption of certain oral medications, so it's worth leaving a gap of a few hours between taking glucomannan and any medication.
