Weight Loss Supplement?
Often marketed for weight loss and type 2 diabetes, glucomannan (also know as “konjac”) is a root primarily composed of an indigestible fiber – which is why it can have a major laxative effect. While scarfing down this stuff in supplement form (it’s currently available in tablet, capsule or powder forms) may help increase fullness and curb appetite, there are smarter and safer ways to do this.
Because of its inability to be absorbed, it may also reduce the absorption of much-needed fat-soluble vitamins A, D, E and K. When taken in combination with certain herbal supplements and diabetic medications, this supplement may also cause a dangerous drop in blood sugar.
Other safety risks include throat and gastrointestinal obstructions, so people that do choose to take this supplement are cautioned to use it in powdered or capsule form, instead of tablets.
