Looking for a natural, effective way to manage your appetite without turning to restrictive diets? Meet Amarasate – a clinically proven, plant-based extract that's changing the game in appetite management.

But what exactly is Amarasate, and why is it the hero ingredient behind Calocurb, a supplement designed to support healthy eating habits? Let's break it down.

From Hops to Hunger Control

You might know hops as a key ingredient in beer, or their long-held place in herbal medicine for their calming and digestive benefits. Now, modern science has uncovered a powerful new use for a particular type of hop and its flower extract: appetite regulation.

After screening more than 900 bitter plants during years of research searching for a natural weight management solution, a team of New Zealand scientists at Plant & Food Research — and in 2014, they found it. A little-known New Zealand hop flower extract was identified as containing bitter compounds capable of activating a feeling of fullness in the body, and Amarasate was born. What makes it special is its ability to activate something called the "bitter brake" — a natural biological mechanism that helps the body manage hunger and promote feelings of fullness in response to eating bitter substances.

How Amarasate Works with Your Body

Amarasate is unique. Through the super-stimulation of the bitter taste receptors in the small and large intestines, Amarasate activates three key satiety hormones: GLP-1 (glucagon-like peptide-1), CCK (cholecystokinin), and PYY (peptide tyrosine tyrosine). This stimulation connects to the brain and reduces cravings by 40%, hunger by 30%, and calorie intake by 18%.1,2

Here's how it helps curb appetite in a natural, science-backed way:

Activates Bitter Taste Receptors in the Gut

Your digestive system is equipped with bitter taste receptors (TAS2Rs) – yes, beyond your tongue! These receptors respond to bitter compounds found in plants like hops and some leafy greens. When Amarasate is released in the upper small intestine, it stimulates TAS2Rs on special enteroendocrine cells there and all down the length of the gut, whose job is to sense the chemical makeup of food. Some of these cells are primed to respond to bitterness, so in response to that stimulation, they release GLP-1, CCK, and PYY.

Triggers Satiety Hormones

When activated by Amarasate's bitter compounds, these cells release satiety hormones that signal the body to stop eating:

  • GLP-1: Slows stomach emptying and increases the feeling of fullness.
  • PYY: Helps reduce hunger and supports portion control.
  • CCK: Slows stomach emptying and raises leptin (another hormone that increases satiety).

Sends a "Stop Eating" Signal to the Brain

The satiety hormones released trigger a feeling of fullness and slow down stomach emptying. Scientists call this stop-eating signal "the bitter brake" — catchy, isn't it? So Amarasate helps you feel satisfied sooner and for longer.

Why Does Bitterness Trigger Fullness?

This response to bitterness is thought to be an evolutionary mechanism designed to help early humans steer clear of potentially dangerous foods, which were often bitter. Think of it as a second line of defence — after taste — against toxic plants, which are often bitter-tasting. Calocurb mimics this natural response to bitterness — without the danger — making it a powerful tool for cutting calorie intake at meals and snacks.

The Science of Delivery: How Amarasate Reaches the Right Place

The bitter brake works best when the bitter compounds are delivered to the part of the gut with the most enteroendocrine cells — the stomach and the lower small intestine.3 However, activation of stomach TAS2Rs can be associated with nausea, vomiting, and even an increase in ghrelin, the major start eating" hormone. (That makes sense from the evolutionary perspective, to help dilute whatever the bitter — potentially toxic — substance might be and also to expel it from the stomach.) So it's important that the Amarasate gets beyond the stomach to the target cells in the small intestine and beyond.

Normal pharmaceutical capsules break down in the stomach, but Calocurb's delayed-release capsule is engineered to dissolve in the duodenum, activating the stop-eating signal and triggering fullness within an hour. Once released from the Calocurb capsule, the Amarasate doesn't dissolve and isn't absorbed; rather, it continues down the length of the gut, activating TAS2Rs all the way, so its effect lasts up to 4 hours. This combination of advanced capsule technology and the bitter brake breakthrough is what makes Calocurb effective.

Amarasate vs. Synthetic Appetite Suppressants

Many appetite control solutions rely on synthetic ingredients or stimulants that can lead to unwanted side effects. Here's how Amarasate compares:

Feature Synthetic Appetite Suppressants Amarasate
Source Synthetic / Lab-created Natural / Derived from hops
Mechanism Super-stimulate "stop eating" hormone receptors and/or alter brain chemistry Works through gut signalling
Side effects Gastrointestinal side effects common (especially with GLP-1 mimics); jittery side effects with stimulants Temporary laxative effect in less than 10% of users when they start Amarasate
Ingredient type Synthetic ingredients or stimulants Plant-based
Hunger regulation Overrides natural hunger signals Supports body's own hunger-regulation processes

With growing awareness around bitter compounds and their role in appetite control, Amarasate is gaining recognition as an innovative, plant-based way to manage hunger — without overriding your body's natural signals.

Frequently Asked Questions

What is Amarasate, and where does it come from?
Amarasate is a patented extract derived from hop flowers grown in New Zealand. It was developed by scientists at Plant & Food Research — part of New Zealand's largest research institute — after screening more than 900 bitter plants to find one with the potential to naturally support appetite regulation.
What is the "bitter brake" and why does it matter?
The bitter brake is the name scientists gave to the body's natural stop-eating signal. It's triggered when bitter compounds — like those in Amarasate — interact with specific receptors on enteroendocrine cells in the gut, causing them to release satiety hormones that tell the brain to stop eating. It's thought to be an evolutionary mechanism that helped early humans avoid potentially toxic bitter plants. Calocurb activates this same response — without the danger.
Why does Calocurb use a special capsule?
Because where the bitter compounds are delivered in the gut matters. It's important to avoid enteroendocrine cells in the stomach and to target those in the small bowel (especially the lower ileum). Normal capsules break down too early. Calocurb's delayed-release capsule is engineered to dissolve specifically in the duodenum, so the bitter brake starts getting activated in exactly the right place.
How is Amarasate different from other appetite supplements?
Most appetite suppressants work by constantly super-stimulating GLP-1 receptors throughout the body (medications like semaglutide or tirzepatide do this because they're mimics of natural GLP-1), altering brain chemistry, or using stimulants — which can cause jitteriness and other unwanted reactions. Amarasate works through gut signalling, activating the body's own hunger-regulation processes rather than overriding them. It's plant-based, contains no synthetic ingredients or stimulants, and works with your body's natural biology rather than against it. Unlike GLP-1 mimics, it doesn't cause continuous (over) stimulation of GLP-1 receptors; instead, its effect lasts for around 4+ hours after taking it.
What's actually in a Calocurb capsule?
Just three natural ingredients: 125 mg of Amarasate hop extract, rosemary oil, and vegetable oil. No fillers, no stimulants, no artificial additives.
Has Amarasate been clinically tested?
Yes. Clinical research has shown that Amarasate can reduce cravings by 40%, hunger by 30%, and calorie intake by 18%. Studies have been conducted in both men and women.4,5,6 Calocurb is the only supplement containing this patented, clinically tested Amarasate formula.
