About Us

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.
