CAROLEAN™: Why this ingredient works and what the science says

Functional plant-based ingredients and their scientific background?

If you have ever reached for food not because you were actually hungry, but because you felt like you couldn't stop thinking about it, you are not alone. Appetite is not just a matter of willpower. Digestion, the feeling of satiety, and hormonal signals that the body sends to the brain also play a major role.

That is precisely why we have included CAROLEAN™ in the Slim GLP-1 Shake. It is a patented combination of plant-based ingredients based on the principle of viscous fiber, which works with the natural feeling of fullness after a meal.

It is not an aggressive stimulant or a "miracle fat burner." CAROLEAN™ works differently. It helps create a longer feeling of satiety and slow down digestion through a natural physical mechanism that has been the subject of long-term scientific research.

What is CAROLEAN™?

CAROLEAN™ is a patented combination of two plant-based ingredients:

Locust bean gum — a fiber extracted from the seeds of the carob tree (Ceratonia siliqua). In the food industry, it is used as a natural thickener and a source of soluble fiber.

Prickly pear (Opuntia ficus-indica) — a plant traditionally used in Mediterranean and Latin American cultures, which is currently being studied in connection with metabolism and weight regulation.

Combining these two ingredients creates a viscous mixture that, upon contact with liquid, changes the consistency of the stomach contents, thereby influencing the feeling of fullness after eating.

How CAROLEAN™ works in the body

After mixing with liquid, CAROLEAN™ creates a thicker gel-like structure in the stomach. This slows down the passage of food through the digestive tract and extends the feeling of satiety after a meal.

The rate of gastric emptying has a fundamental impact on how long the feeling of fullness lasts after eating. The slower the stomach processes food, the longer the sensation of satiety can persist.

Research focused on viscous fibers shows that the texture and density of food can influence overall energy intake as well as the subjective feeling of hunger. Furthermore, studies tracking locust bean gum specifically have described a slowing of gastric emptying in healthy volunteers.

The feeling of stomach fullness is also related to hormonal signaling in the body. A longer feeling of fullness is associated, for example, with lower production of the hormone ghrelin, which is often referred to as the hunger hormone.

Conversely, hormones such as peptide YY (PYY) are linked to satiety signals and the regulation of food intake. These mechanisms have long been the subject of research in the field of metabolism and appetite control.

At the same time, viscous fibers can slow down the contact of nutrients with the intestinal mucosa, contributing to a more gradual absorption of carbohydrates and fats and a more stable course of digestion after a meal.

What research says about CAROLEAN™ ingredients

It is important to mention that available studies relate to the individual ingredients or the general mechanism of viscous fibers, not to the Slim GLP-1 Shake product as a whole.

Research focusing on food viscosity confirms that a thicker food consistency can influence the feeling of fullness and subsequent energy intake. Additionally, studies observing locust bean gum have shown a slowdown in stomach emptying after a meal.

Research into hormones like ghrelin or PYY describes their important role in regulating appetite and the feeling of satiety after eating.

At the same time, review studies focusing on Opuntia ficus-indica examine its potential relationship to metabolism and weight regulation, especially in conjunction with dietary and lifestyle adjustments.

Why we chose CAROLEAN™

When formulating the Slim GLP-1 Shake, we were looking for an ingredient that is based on the natural principle of fiber, has a documented mechanism of action, and is suitable for daily use.

CAROLEAN™ caught our attention precisely because it works with the natural feeling of satiety and the physical properties of fiber, rather than on the principle of aggressive stimulation of the organism.

This is not an extreme solution or a short-term fix. It is a well-thought-out part of the formula designed to help create greater comfort when managing appetite throughout the day.

Summary

CAROLEAN™ is not a medicine or a substitute for a varied diet. It is a functional fiber designed to help create a longer feeling of satiety and support comfort after eating.
