Glucomannan, the primary fiber in konjac root, is one of the most water-absorbent dietary fibers known — it can expand many times its dry weight when it meets liquid in the stomach.

That expansion is the mechanism behind its reputation for supporting satiety and making portion control feel more manageable.

It's worth taking LipoJaro with a full glass of water for this ingredient specifically, since fiber of this type works best with adequate hydration.

Where it sits in the formula: one of 11 dosed ingredients on the LipoJaro label, alongside Vitamin B2 (Riboflavin), Mangosteen Powder, Prickly Pear Extract 4:1, Cinnamon Bark Extract 10:1.
