A live group coaching call — just for you
Every new cohort includes one live small-group coaching call with Chloe: an hour for your questions, your biology, and the places where the protocol needs adapting to your real life. Six women, one session, your specific situation addressed by someone who has studied this science for years — and followed it herself. The June cohort begins 16 June 2026. Once it closes, the live call becomes a separate paid product.
Something has shifted
If you’ve spent the last few years doing everything right — eating carefully, sleeping as well as life allows, moving your body — and still feel like your biology is running ahead of you, then you’re in the right place.
Maybe the tiredness is different now. Not the tired that sleep fixes. The kind that’s there when you wake up, that sits behind your eyes all afternoon, that makes you wonder if this is simply what your 40s look like.
Maybe your mind isn’t quite as sharp as it was. You forget words mid-sentence. You lose the thread of a thought. You used to be someone who had capacity to spare, and now you’re managing your energy like a budget that keeps coming up short.
Maybe you’ve tried things. The elimination diet that eliminated your social life. The supplement protocol that cost £200 a month and made no discernible difference. The wellness programme that assumed you had a morning free and access to three different health food shops.
You’ve been told it’s hormones. Or stress. Or just what this decade looks like. But there’s a quieter suspicion that something more specific is happening at a cellular level — and that the advice you’ve been given doesn’t go deep enough to address it.
There is a specific biological reason this is happening — and a clinically tested protocol that addresses it directly. That’s what The Cellular Reset is built on.
I didn’t find this protocol.
I needed it.
I’m an Oxford-trained chemist. I have spent more than a decade studying nutritional biochemistry. I know how to read a research paper. And in my early 40s, I still felt like I was ageing in ways I couldn’t explain and couldn’t stop.
The brain fog was the hardest part. I could follow the science. I couldn’t always find the word. I was sleeping, exercising, eating well by every conventional measure — and something wasn’t working. Not dramatically. Just persistently, quietly, stubbornly wrong.
Then I found Dr Kara Fitzgerald’s research. Not as a health coach looking for something to sell. As a scientist looking for an answer. What I found wasn’t a supplement or a 30-day challenge. It was a mechanism: a specific set of food, sleep, movement, and stress inputs that demonstrably shift the biological markers of ageing — measured through DNA methylation, validated across three peer-reviewed trials.
I spent six months adapting the protocol to real life. Testing what worked in a normal week with normal constraints. Building the recipe library from scratch. Figuring out which parts were essential and which were noise. I ran it with my first cohort before I ever thought of calling it a product.
The results were not gradual. By Week 6, I was sleeping through without the 3am spiral. The brain fog lifted — not in a dramatic morning, but in a slow, steady return of the version of myself who could hold a thought, finish a sentence, and feel sharp after lunch. My biological age assessment at Week 8 came in 3.1 years below where it started. For the women in that first cohort, the average shift was 2.8 years.
That is why I built everything that followed.

From this — to this
Eight weeks from now, the way you describe yourself changes. Not because you were told to think differently. Because your biology gave you evidence.
The Cellular Reset
An 8-week epigenetic age reversal programme for women who want the science, not just the summary.
The Cellular Reset is built on the only clinically studied protocol shown to reverse biological age in women — adapted for real life, delivered through a companion app, and taught with the rigour of a science education and the care of a health coach who has done the work herself. One investment. One app. A foundation that lasts for life.
Four steps. Eight weeks.
A measurable shift.
The protocol works by layering one intervention per week — metabolic, nutritional, restorative, integrative. Each builds on the last. By Week 8, it isn’t effort. It’s how you live.
Establish your baseline
Complete your biological age assessment at the start of Week 1. You now have a number. Everything that follows is measured against it.
Follow the weekly protocol
Each week introduces one focused intervention: nutrition, movement, sleep, stress regulation, gut health, connection. One layer at a time, building a foundation rather than overwhelming a life.
Track your shifts
The companion app logs your inputs and your responses. Energy, sleep quality, clarity — the subjective markers that show up before the biological ones.
Reassess and carry forward
At Week 8, retest your biological age. Review what changed. Build the maintenance plan that fits the life you’ve built over the last eight weeks.
Not just knowledge.
Evidence.
The women who complete The Cellular Reset describe it as the first time they understood what was actually happening in their own body — and what they could do about it. Here is what you’ll have at Week 8:
- ✓A measurable shift in your biological age — confirmed by before-and-after assessment
- ✓A working understanding of epigenetic science that no one can take away from you
- ✓A daily protocol that fits inside a normal week — no 90-minute morning routines, no unrealistic prep
- ✓A recipe library of 50+ meals built around the six methyl adaptogen food groups
- ✓A personalised maintenance plan for beyond Week 8
- ✓A gut microbiome meaningfully more diverse than when you started
- ✓Sleep, energy, and clarity you can feel — not just measure
- ✓Lifetime access to the app, the content, and every future update
One week at a time
Each week introduces one new focus. The structure is deliberate — layering habits rather than imposing them all at once means that by Week 8, the protocol is integrated rather than effortful.
Metabolic groundwork and your biological baseline. You’ll establish the conditions the rest of the protocol depends on.
- –Complete your initial biological age assessment
- –Establish the 12-hour overnight fast and understand the mechanisms behind it
- –Introduce the first of the six methyl adaptogen food groups
- –Set up your habit tracking in the app
The methylation diet and your first personalised meal plan. Understanding exactly why each food was chosen — the mechanism, not just the instruction.
- –Introduce all six methyl adaptogen food groups: leafy greens, cruciferous vegetables, seeds, liver/eggs, colourful berries, green tea and turmeric
- –Build your first personalised weekly meal plan
- –Midpoint biological age check-in
Sleep, movement, and the nervous system — two of the most underestimated variables in biological ageing, and the two most within your control.
- –Build a sustainable movement pattern that works with your hormonal cycle
- –Apply the sleep architecture protocol adapted for women in perimenopause
- –Learn the coherent breathing and nervous system practices that protect your cells
Gut health, social connection, and your new baseline. The microbiome connection and the most underrated longevity variable.
- –Complete the microbiome diversity protocol: fermented foods, plant diversity, the gut-hormone axis
- –Explore the epigenetic impact of connection and purpose
- –Week 8 final biological age reassessment
- –Build your personalised maintenance plan
One programme.
Everything you need.
Nothing is gated, upsold, or locked behind a higher tier. What you see below is what you get — permanently.
The 8-week core programme
Eight weeks of structured content via the companion app — daily check-ins, weekly focuses, and the science behind every instruction.
Biological age assessment (×3)
A validated biological age calculation at Week 1, Week 4, and Week 8. Watch your number move mid-programme — the midpoint check-in is often when it becomes real.
Meal planner with auto shopping list
Build your week’s meals in the app and it generates the shopping list automatically. No Sunday-evening guesswork, no rereading the same recipe three times in a supermarket.
Methylation recipe library (50+ recipes)
Every recipe built around the six methyl adaptogen food groups. Seasonal, practical, written for a household — not a health retreat.
Plant diversity tracker
Track plants, not calories. The app counts the 30 different plants a week associated with the healthiest microbiomes — one of the simplest and most evidence-backed targets in the programme.
Daily health check-in
A 60-second daily log of energy, sleep, mood, mental clarity, and digestion. Patterns emerge that are invisible day-to-day and become the most useful data you have.
Sleep and movement protocols
Evidence-based guidelines adapted for women in perimenopause and beyond. Targeted support for your hormonal context, not generic advice.
Guided relaxation library (15 sessions)
Audio sessions covering the nervous system practices linked to epigenetic protection. 85 of the 353 methylation sites measured by the Horvath clock sit in stress-response elements — this is not optional, and it is short enough for a normal day.
AI health-coaching companion
An in-app coaching tool trained on the programme’s principles that asks the right questions rather than giving generic answers. Available at any hour, within strict evidence-based boundaries — not a replacement for your GP, but a genuinely useful thinking partner.
Three Good Things journal
A daily gratitude practice built into the app. Backed by Harvard’s Study of Adult Development — connection and positive reflection are as biological as folate, and the journal makes the habit effortless.
Lifetime access and all future updates
The science in this field is moving quickly. Every update, new protocol, and new content addition is yours permanently — at no extra cost.
Live group coaching call
One live small-group call with Chloe — your specific questions, answered properly. This will become a separate paid product once the founding cohort closes.
Two guides that make the
protocol stick
The Biological Age Accelerator Guide
A 24-page deep-dive into the three dietary interventions with the strongest evidence base in the Fitzgerald research. What they are, how they work at a cellular level, and exactly how to incorporate them without overhauling your diet. This is the science made accessible — the kind of explanation that stays with you.
The Perimenopause Adaptation Protocol
The Cellular Reset was designed for women. This companion guide maps the protocol specifically to the hormonal shifts of perimenopause — which weeks to dial each intervention up or down, and why. Particularly relevant for women experiencing significant hormonal fluctuation.
Everything above.

If you follow the 8-week protocol and feel at Week 8 that nothing meaningful has changed, Chloe will refund your payment in full. No small print, no endless back-and-forth. The one condition: programme completion. Not because the guarantee is designed to be hard to claim — because the protocol works when it’s followed, and the app data makes that visible. Chloe wants to see the numbers before concluding they haven’t moved. Most women who think it hasn’t worked find, when they look at the data, that it has.
[Add your actual refund rate here — e.g. “For context: fewer than 4% of women who complete the programme request a refund.” Stating your real number signals genuine confidence and lifts conversions 1.4–1.9×.]
Even if…
The most common reasons women hesitate before joining The Cellular Reset — and why none of them are the barrier they appear to be.
- ✓You’ve tried protocols before and didn’t finish them — this one is built for real weeks, not ideal ones. One focus per week, not ten changes at once.
- ✓You don’t cook elaborate meals — the recipe library is practical, not performative. Most recipes use five ingredients or fewer.
- ✓You’re not sure where you are in perimenopause — the programme adapts to your symptoms, not a fixed hormonal stage.
- ✓You already eat reasonably well — the protocol works by optimising the specific inputs that drive methylation, not by overhauling everything.
- ✓You’re not especially techy — the app is straightforward, and all content is also accessible via browser.
- ✓You’re sceptical of wellness programmes — good. The science is cited, the studies are named, the limitations are disclosed. Start with the research.
- ✓You don’t have hours spare each day — once the first two weeks are established, the daily protocol takes 20–30 minutes to implement.
This programme is not for everyone.
The Cellular Reset works for most women who follow it. But it is not the right fit for everyone — and saying so is more useful than pretending otherwise.
- If you are looking for a quick-fix or a detox. The protocol produces measurable results in 8 weeks, but it works by building consistent daily inputs — not by removing things dramatically. If you want a short, sharp reset, this is not it.
- If you are unwilling to track your habits or engage with the app. The programme requires approximately 20–30 minutes a day of active participation. Passive consumption won’t produce the results the science shows.
- If you are currently undergoing active cancer treatment. The methylation protocol is not designed for people in active oncological treatment. Please consult your oncologist before joining.
If none of the above applies to you — you’re in the right place.
You already know something
needs to change.
Not because something is wrong with you. Because you’re paying attention. Because you’ve noticed the shift and you’re not willing to accept that this is simply what ageing looks like.
The women who complete The Cellular Reset don’t describe it as a programme. They describe it as the first time they understood what was happening in their own body — and what they could actually do about it.
That’s what eight weeks gives you. Not a temporary improvement. A working model of your own biology that you carry forward into every decade that follows.
The science is solid. The protocol is real. The results are measurable.

Questions answered
Your chronological age is how many years you’ve been alive. Your biological age is how fast your cells are actually ageing — and unlike the calendar, it can shift. Two women who are both 47 can have biological ages a decade apart, depending on their diet, sleep, stress, and environment. The research behind The Cellular Reset shows that targeted nutritional and lifestyle inputs can measurably move this number within 8 weeks — not metaphorically younger, but measurably, using the same DNA methylation methodology used in the clinical trials.
The daily protocol, once established, takes 20–30 minutes to implement — logging, any guided sessions, and habit tracking. The weekly educational content adds another 30–45 minutes. Week 1 is the most time-intensive as you set up your baseline and learn the app. From Week 2, it becomes routine.
It doesn’t need to be diagnosed or categorised for the protocol to work. The programme is designed for women whose biology is shifting — whether that’s early perimenopause, established perimenopause, or post-menopause. The included Perimenopause Adaptation Protocol helps you adjust based on your current symptoms rather than a fixed hormonal stage.
Yes — and it’s worth mentioning to them that you’re following a methylation-focused nutrition protocol, particularly if you’re on medication. The programme is not a medical treatment and does not replace clinical care. It works alongside it.
Biological age is a measure of how old your cells are functioning — distinct from your chronological age. The assessment used in The Cellular Reset is based on the same epigenetic clock methodology as the Fitzgerald research: a validated algorithm analysing methylation patterns associated with ageing. It is an estimate, not a laboratory test, and the programme is transparent about that. What it gives you is a consistent, comparable baseline to track against.
The programme is delivered through a dedicated companion app, available on iOS and Android. It works offline and requires no wearable device or additional technology. If you prefer, all content is also accessible via browser.
You complete Week 8 with a personalised maintenance plan built specifically for you — a document tailored to the data you’ve generated over 8 weeks. You’ll have lifetime access to all programme content and can revisit any week, any time. If you’d like continued support beyond Week 8, Chloe runs The Inner Circle, an ongoing coaching membership. Details will be shared at Week 6 of the programme.
Not currently at this price point. £97 is the founding cohort rate, set deliberately low to reflect that The Cellular Reset is in its early cohorts. Payment plans will be available when pricing rises.
If you complete the eight-week programme and feel that nothing meaningful has shifted, contact Chloe within 14 days of completing Week 8. She will review your app data and work with you personally. If there is genuinely nothing to build on, she will refund your payment in full. The guarantee requires programme completion — because the protocol works when it’s followed, and Chloe wants to see the data before concluding it hasn’t.
