Calocurb works by activating what Plant & Food Research scientists call ‘the bitter brake’. ‘The bitter brake’ occurs when bitter compounds (in this case, a hops flower extract) interact with specific receptors in the gut to send a ‘stop-eating signal’ to the brain.

How Amarasate™ works

Bitter Foods & Fullness

The active ingredient in Calocurb is derived from a rare, New Zealand grown hops flower recognised for its high levels of Alpha acids. We have long known that bitter compounds with high levels of Alpha acids can support a feeling of fullness.

Amarasate™ supports management of appetite, overeating, and hunger so you can feel confident about healthy eating - without feeling jittery.
