About

Xentra Health is a specialist supplement development house dedicated to creating science-based, neuroendocrinology-driven formulations focused on:

  • Appetite regulation

  • Weight management

  • Cognitive performance

  • Metabolic health

Xentra Health was founded on a simple but transformative belief:
 lasting appetite control begins with understanding the biology behind hunger, cravings, satiety, and mood.

  • Not through stimulants.

  • Not through fads.

  • Not through synthetic hormone-mimicking GLP-1 drugs or injectable treatments.

But through neuroendocrinology — the real hormonal and neurological signals that shape how we eat, feel, and function every day.

Xentra Health exists to bring this level of science into everyday life, transforming advanced appetite research into accessible, practical solutions.

What makes Xentra Health different:

  • Science-first formulation guided by validated research

  • Expert-led development with world-class specialists

  • GMP manufacturing in the UK/EU

  • EFSA-compliant standards

  • Transparent formulation (no hidden blends)

  • Continuous R&D and innovation

Where Scientific Insight Meets Real-World Solutions

At the centre of Xentra Health is our scientific partnership with Dr. Juliana Maynard, PhD, one of the UK’s leading Neuroendocrinologists. Her groundbreaking PhD thesis on appetite regulation and obesity management laid the foundations for the Maynard Formula™, the scientific backbone of Xentra Health’s innovation pipeline — including the World’s First Clinically Inspired Appetite Regulation Supplement Drink.

 

Her research spans:

  • Ghrelin and hunger signalling

  • Satiety-driving gut and nutrient pathways

  • Neurochemical reward circuits

  • Mood–appetite interactions

  • Leptin and orexigenic signalling

  • Fibre-driven satiety and gastric emptying dynamics

This depth of scientific oversight ensures every Xentra Health formulation is clinically rational, mechanistically validated, and aligned with human biology — built to support rather than override the body’s natural systems.

The Maynard Formula™ represents years of specialised research and integrates:

  • Gut-derived peptide science

  • Fibre + flavour satiety engineering

  • Neurotransmitter optimisation

  • Slow-release gastric modulation

  • Reward-circuit recalibration for reduced emotional eating

This multi-pathway approach powers Grehlin-X®, and the next generation of Xentra Health’s advanced formulations.

Xentra Health’s product is guided by three principles:

1. Scientifically Grounded

Ingredients are chosen for mechanistic evidence, human research, and clinical rationale — not trends.

2. Real-Life Usability

Once-daily sachets, clean flavours, instant mixing, and letterbox-friendly packs support everyday consistency.

3. Results You Can Feel

Appetite regulation, satiety, craving reduction, mood support, and metabolic balance — aligned for maximum impact.

 

 

 

 

Science-led appetite support, built around human biology

Xentra Health is a specialist supplement development company focused on creating science-based, neuroendocrinology-driven formulations designed to support appetite regulation, cravings, satiety, mood, and metabolic balance.

  • Our Approach

    Built on biology, not trends

    Xentra Health was founded on a simple belief: lasting appetite support begins with understanding the biological systems that influence hunger, cravings, fullness, mood, and behaviour. Rather than relying on stimulants, quick fixes, or restrictive approaches, Xentra Health focuses on the real hormonal and neurological pathways involved in appetite regulation and metabolic balance.

    Our formulations are developed around neuroendocrine science, translating advanced research into practical, accessible daily support designed to work with the body’s natural systems rather than override them.

Turning advanced research into practical support

Appetite is regulated by a complex communication network between the gut and the brain. Hormones, neurotransmitters, reward pathways, digestive signalling, and behavioural responses all influence how we experience hunger, cravings, fullness, and energy balance.

Xentra Health exists to bring this level of scientific understanding into everyday life through formulations designed around consistency, usability, and real-world routines.

This philosophy led to the development of The Maynard Formula™, the scientific framework that powers Ghrelin-X® and future Xentra Health innovations.

A multi-pathway approach to appetite regulation

The Maynard Formula™

Gut–Brain Communication

The gut and brain are constantly exchanging signals that influence appetite, satiety, cravings, and food-related behaviour. Supporting healthy gut–brain communication forms a central part of the Maynard Formula™ approach.

Satiety & Fullness Signalling

The formulation strategy behind Ghrelin-X® includes ingredients selected to support fullness signalling and appetite balance, helping meals feel more satisfying and supporting more consistent eating patterns throughout the day.

Mood & Reward Pathways

Cravings are influenced not only by physical hunger, but also by emotional and neurological reward pathways. The Maynard Formula™ was developed to support pathways associated with mood balance, reward signalling, and behavioural appetite responses.

Metabolic Balance

Metabolic health is closely connected to appetite regulation, hormonal signalling, and energy balance. Xentra Health formulations are designed around a multi-disciplinary, science-backed approach to supporting these interconnected systems.

Guided by Scientific Expertise

Developed with Dr Juliana Maynard, PhD

At the centre of Xentra Health is its scientific partnership with Dr Juliana Maynard, PhD, a UK neuroendocrinologist whose research focuses on appetite regulation, obesity management, hormonal signalling, and neuroendocrine pathways.
