GLP Peptiva™ – The Science

GLP Peptiva™ offers a science-led approach to supporting appetite regulation and post-meal glucose balance. As awareness of GLP-1 continues to grow, more people are recognising the important role appetite hormones play in hunger, fullness and the body’s response to food.

The rise of GLP-1 medications has transformed the way we think about appetite, weight management and metabolic health.¹ While these medications have brought incretin biology into the spotlight, they have also sparked wider interest in understanding how the body’s natural appetite regulation pathways work.

For many adults, maintaining control over hunger, cravings and energy levels can feel like a daily challenge. With 66% of adults in England now living with overweight or obesity,² there is growing interest in understanding the biological factors that influence appetite, weight management and metabolic health.

Appetite regulation is influenced by a complex network of biological signals that help determine when we feel hungry, when we feel satisfied and how our bodies respond to food after a meal.³

At Regulate Health, we believe these natural processes shouldn’t be overridden — they should be supported.

That’s why we’ve chosen clinically studied ingredients backed by human research and designed to work alongside your body’s own biological pathways. Rather than relying on gimmicks or quick fixes, our approach focuses on supporting the hormones and metabolic processes involved in appetite regulation, glucose balance and overall metabolic wellbeing.

At the heart of GLP Peptiva™ is Nextida® GC, a patented and clinically studied collagen peptide composition specifically developed to support appetite regulation and metabolic health.

Unlike traditional collagen supplements, which are primarily associated with skin, hair or joint health, Nextida® GC has been researched for its ability to support the body’s natural response to food.

What makes Nextida® GC unique is its clinically studied ability to support the body’s natural incretin response following a meal. Incretins are natural hormones released by the gut after eating that help regulate hunger, fullness and the body’s response to food.

In a placebo-controlled human clinical trial, participants consumed Nextida® GC before a carbohydrate-rich meal. Researchers observed significant improvements across several key markers involved in appetite regulation, glucose metabolism and insulin response.⁴

The study demonstrated that Nextida® GC increased the secretion of both GLP-1 (Glucagon-Like Peptide-1) and GIP (Glucose-Dependent Insulinotropic Polypeptide), two important incretin hormones involved in appetite regulation, satiety and glucose metabolism.

Together, these findings suggest that Nextida® GC works alongside the body's natural biological pathways to support a healthier metabolic response to food.

One of the most significant findings from the clinical study was an increase in GLP-1 secretion following supplementation with Nextida® GC.

GLP-1 is a naturally occurring hormone released by the gut after eating and is one of the body’s key regulators of appetite and satiety. It helps communicate feelings of fullness to the brain and plays an important role in regulating appetite, insulin secretion and blood glucose levels.⁵

Compared with placebo, participants consuming Nextida® GC experienced approximately 25% greater GLP-1 secretion following a meal.

This finding is particularly important because GLP-1 sits at the beginning of a chain of physiological events involved in appetite regulation, insulin secretion and blood glucose control.

Many people struggle with persistent hunger, cravings or feeling unsatisfied after meals. By supporting the body’s natural GLP-1 response, Nextida® GC may help strengthen the biological signals involved in fullness and appetite regulation.⁵

Gastric emptying refers to the rate at which food leaves the stomach and moves into the small intestine.

This process plays an important role in appetite regulation and blood glucose control. When food leaves the stomach more gradually, nutrients are delivered to the intestine at a slower rate, helping the body respond more steadily following a meal.

In the clinical study, participants consuming 10 g of Nextida® GC experienced gastric emptying that was approximately 37.2 minutes slower than those receiving placebo.

Slower gastric emptying is one of the ways the body naturally helps regulate appetite and post-meal glucose responses. It is also one of the physiological actions associated with GLP-1 following food intake.⁵

While individual responses will vary, slower gastric emptying may help support:

• Feeling fuller for longer after meals.
• Improved satisfaction following eating.
• A steadier release of nutrients into the bloodstream.
• A more gradual post-meal glucose response.

While GLP-1 often receives most of the attention, it is only part of the story.

The clinical study also demonstrated an increase in GIP, another important incretin hormone released following a meal.

Working alongside GLP-1, GIP helps coordinate the body’s metabolic response to food and plays an important role in healthy glucose and insulin regulation.⁶

Compared with placebo, participants consuming Nextida® GC experienced approximately 60% greater GIP secretion.

The fact that Nextida® GC supports both GLP-1 and GIP suggests that it works across multiple interconnected pathways involved in appetite regulation, glucose metabolism and insulin function, rather than targeting a single mechanism alone.⁶

Every time we eat carbohydrates, our blood glucose levels naturally rise. This is a normal and healthy physiological response to food.⁷

However, for some people, these rises can be larger and more rapid than ideal, resulting in what is commonly referred to as a “post-meal glucose spike” — a rapid rise in blood glucose following a meal.

According to Diabetes UK, more than 12 million people in the UK are currently living with either diabetes or prediabetes,⁸ highlighting growing concerns around glucose regulation and metabolic health.

Large fluctuations in blood glucose are often followed by a rapid decline, sometimes referred to as a “glucose crash”. Research suggests these dips may be associated with increased hunger and a greater likelihood of eating sooner after a meal.⁹

In the clinical study, participants consuming Nextida® GC experienced approximately 42% lower post-meal glucose spikes compared with placebo.

A healthier post-meal glucose response may help support:

• More stable energy levels throughout the day.
• Reduced energy dips following meals.
• Healthy appetite regulation.
• A more balanced response to food.

Potential benefits are based on observed relationships between glucose regulation, appetite and subsequent food intake.⁹

Insulin is a hormone produced by the pancreas that helps move glucose from the bloodstream into cells, where it can be used for energy.

Following a meal, GLP-1 and GIP work together to help coordinate the body’s insulin response, ensuring glucose is managed efficiently.

Researchers observed improvements in insulin response following supplementation with Nextida® GC.⁴

Interestingly, the research suggests that by supporting the release of GLP-1 and GIP before blood glucose levels begin to rise significantly, the body may be better prepared to manage incoming nutrients following a meal.

Together with the observed increases in GLP-1 and GIP and the reduction in post-meal glucose spikes, these findings suggest that Nextida® GC supports a more balanced physiological response to food.

The clinical research on Nextida® GC demonstrates more than a single outcome. It reveals a connected sequence of physiological responses that help explain how the ingredient supports appetite regulation and glucose balance.

Together, these findings suggest that Nextida® GC works alongside the body’s natural biological pathways to support a healthier response to food. This integrated response is what makes Nextida® GC unique and forms the foundation of GLP Peptiva™.

Alongside Nextida® GC, GLP Peptiva™ contains chromium, an essential trace mineral that contributes to the maintenance of normal blood glucose levels and normal macronutrient metabolism.¹¹

While Nextida® GC supports the body's natural incretin response, chromium provides complementary nutritional support for healthy glucose metabolism and insulin function.¹⁰

Together, these two ingredients provide targeted support for the body's natural appetite and glucose regulation pathways.

Chromium contributes to:

• The maintenance of normal blood glucose levels*
• Normal macronutrient metabolism*
