Question

What is the recommended usage percentage or dosage for Konjac glucomannan (Konjac Gum) when used either as a dietary supplement or as a thickener/gelling agent in formulations?

Answer

Konjac Glucomannan (Konjac Gum) is primarily used as a dietary fiber supplement for weight management and digestive health. The usage percentage is typically expressed as a daily dosage for consumption, not a percentage in a formulation.

Recommended Daily Dosage (for Dietary Supplement Use):

  • For Weight Loss/Appetite Control: The typical recommended dosage is 1 to 4 grams per day, usually divided into 1-gram doses taken 30 minutes to 1 hour before main meals.
  • Important Safety Note: It is crucial to consume Konjac Glucomannan with at least 240 ml (8 oz) of water per gram of powder to prevent choking or blockage, as it expands significantly in the stomach.

  • If Konjac Glucomannan is used as a thickener or gelling agent in food or cosmetic formulations, the usage percentage would vary widely depending on the desired viscosity, typically ranging from 0.1% to 1.0% or more.*
