Konjac glucomannan comes from the root of the konjac plant and is one of the most viscous dietary fibers known — it isn't digested by the small intestine at all.

In BrainLive, it's the first of three fermentable fibers, working alongside resistant pea starch and baobab fiber rather than standing alone.
In this formula: Konjac Glucomannan is one of five named actives — see the full mechanism on our how it works page.
