Most supplement companies lead with marketing. We lead with science. And behind that science is one person more than any other: Dr. Greg Potter.
Greg is Coastline's Chief Science Officer. He's the one who selected our 13 ingredients, set the clinical doses, and designed the morning-and-evening system you hold in your hands. But before he was formulating supplements, he spent over a decade studying how sleep, nutrition, and circadian biology shape human health — and working with some of the most demanding organizations on the planet.
Here's the story of how a British exercise scientist ended up building what we believe is the most evidence-backed longevity supplement system available.
From Loughborough to Leeds: the academic foundation
Greg's path started at Loughborough University — one of the UK's top institutions for sport and exercise science. He earned his BSc in Exercise Science and his MSc in Exercise Physiology there, and between degrees, he took an internship in the sports science and sports medicine department of the Rugby Football Union.
He wasn't just studying performance in a lab. As a coach at Loughborough, Greg trained a sprinter who went on to win four gold medals at the European Championships.
But Greg wanted to understand something deeper than athletic output. He wanted to understand the biological systems that drive health across a lifetime — not just during competition. That led him to the University of Leeds, where he completed his PhD in sleep, nutrition, and metabolic health.
His doctoral research focused on the intersection of circadian rhythms, diet timing, and metabolism — work that would later become the scientific backbone of Coastline's formulation philosophy. The research was featured by the BBC World Service, The Washington Post, Reuters, and TIME Magazine.
What Greg studies (and why it matters to you)
Greg's expertise sits at a unique crossroads: where sleep science meets nutrition science meets chronobiology. Most researchers specialize in one of these. Greg studies how they interact.
His core insight — and the one that shapes everything about Coastline — is that when you do something matters as much as what you do. When you eat. When you exercise. When you take your supplements. Your body doesn't process a molecule of creatine at 7am the same way it processes it at 11pm. Your circadian clock regulates nearly every metabolic pathway in your body.
This is the science behind chrononutrition — an emerging field that Greg has been publishing on since his doctoral work. It's also the reason Coastline isn't a single pill. It's a morning system and an evening system, designed around your body's natural rhythms.
Beyond the lab: real-world applications
What makes Greg unusual among researchers is the range of people he's worked with. Academic scientists often stay in academia. Greg took his knowledge to the field.
He's worked with the United States Naval Special Warfare Command — the umbrella that includes the Navy SEALs — on health and performance optimization. When the people responsible for the most physically and cognitively demanding operations on earth need help optimizing sleep and nutrition, they called Greg.
He serves as a health coach at the London Psychiatry Clinic, where he works with patients on sleep disorders, circadian disruption, and the behavioral science of habit change.
He co-founded Resilient Nutrition, a UK-based company that leverages nutritional science to develop functional foods and supplements.
He sits on the advisory board for Food For The Brain, a charitable foundation focused on the link between nutrition and mental health.
And he's a member of the Translational Research Team at Voloridge Health, working on translating scientific findings into real-world health interventions.
Reason & Wellbeing: making science accessible
One of the things that drew us to Greg was his ability to communicate. A lot of brilliant scientists can't explain their work to a non-specialist. Greg can — and he does, every week.
His YouTube channel, Reason & Wellbeing, features long-form conversations with some of the world's leading researchers in longevity, sleep, exercise, and brain health. Guests have included:
- Prof. Barry Halliwell — the world's leading authority on ergothioneine and antioxidant biology
- Dr. Vijay Yadav — lead researcher of the landmark 2023 taurine and aging study published in Science
- Dr. Darren Candow — a leading expert on creatine's effects beyond muscle, including brain health and bone preservation
- Dr. Rebecca Strawbridge — researcher studying microdose lithium and neuroprotection
- Prof. Steven Austad — one of the foremost biogerontologists in the world
- Dr. Stuart McGill — the world's top spine biomechanics researcher
- Dr. Tommy Wood — a neuroscientist at the University of Washington
As Dr. Wood put it, Greg is "one of those rare scientists" who combines deep research expertise with the ability to make information "easily understandable and actionable."
These aren't casual podcast chats. They're substantive, evidence-based deep dives — many running 60 to 90 minutes — into the mechanisms behind health and aging. And they're a window into the kind of scientific thinking that went into building Coastline.
How Greg formulated Coastline
When Greg came on board as Chief Science Officer, he assembled a team of four experts spanning sleep science, molecular medicine, naturopathic medicine, and clinical practice. Together, they built a formulation philosophy shaped by decades of combined research. A few principles define their approach:
Clinical dosing, not label decoration. Every ingredient in Coastline is dosed at levels shown to be effective in peer-reviewed research. Not "fairy dusted" at trace amounts so we can list more ingredients on the label.
Ingredients with dedicated biological infrastructure. Greg gravitates toward compounds that the body has evolved specific mechanisms to absorb and utilize. Ergothioneine, for example, has its own dedicated transporter (OCTN1) — a strong signal that it plays an essential biological role. The body doesn't build custom transporters for unimportant molecules.
A systems approach, not a single-molecule bet. Aging isn't caused by one thing. It involves 12 identified hallmarks — from mitochondrial dysfunction to genomic instability to cellular senescence. Greg selected 13 ingredients that address multiple hallmarks across every major body system, rather than betting everything on one trendy molecule.
Chronobiology-informed timing. The morning blend and softgels deliver energy-supporting, cognitive, and metabolic ingredients when your body is primed to use them. The evening capsules deliver calming, recovery, and neuroprotective ingredients when your body is preparing for rest and repair. This isn't arbitrary — it's chrononutrition applied to supplementation.
"The 13 ingredients chosen for Coastline are the most scientifically supported, and clinically validated supplements yet to be discovered."

What comes next
Greg continues to research, publish, and host Reason & Wellbeing — and the insights from that work feed directly into how Coastline evolves. Science doesn't stand still, and neither does our formulation philosophy.
Over the coming weeks, we'll be publishing a series of deep dives into the science behind Coastline — drawn directly from Greg's research and his conversations with world-class scientists. Topics will include the emerging research on ergothioneine, what a landmark taurine study means for aging, why your sleep tracker might be misleading you, and what chrononutrition means for your daily routine.
This is the kind of science we built Coastline on. Not marketing claims. Not influencer endorsements. Peer-reviewed research, clinical dosing, and a formulation designed by someone who's spent his career at the intersection of sleep, nutrition, and human performance.
