Liz Earle joins Tim Gray to break down why perimenopause often starts in your late 30s, the real difference between bioidentical and synthetic HRT, and why mitochondrial health is the master key to ageing well.They explore why mitochondria run the show at a cellular level, why the separation of oral and medical care has cost women decades of unnecessary suffering, and why the three inputs your mitochondria need most have been free all along.

In this episode, we explore:

➡︎ Why mitochondria are the master key to ageing Liz explains why everything from energy production to DNA repair, hormone signalling and immune function runs through the mitochondria, and why looking after them is the most foundational thing you can do for longevity.
➡︎ The difference between body identical and synthetic hormones Liz breaks down why bioidentical or body identical hormones fit the cell receptor like a key in a lock, why synthetic hormones do not, and why virtually all modern HRT is now body identical and available on the NHS.
➡︎ Why perimenopause starts much earlier than most women think Tim and Liz discuss how perimenopause can begin in the late 30s, why symptoms are so easily misattributed to life stress, and why blood tests alone are an unreliable way to diagnose it.
➡︎ The three ancestral inputs mitochondria actually need Liz shares how light, living water, and grounded connection to the earth were the original mitochondrial inputs for human health, and why disconnecting from all three is quietly driving modern disease.
➡︎ Why the electric light bulb was one of the most destructive things to happen to human health Tim and Liz discuss how artificial light at night disrupted circadian rhythm, hormonal signalling, and cellular repair in ways we are only now beginning to understand.
➡︎ What 40 years in the wellness space changed her mind about Liz reflects on moving from pro-supplement to anti-supplement and back again, and why food-sourced, highly researched, mitochondria-specific supplements are now her focus.Liz Earle is a bestselling author, broadcaster, and one of the most trusted voices in UK wellness. With over 40 years of research and writing across nutrition, hormones, longevity, and skincare, she has consistently been ahead of the curve on topics from gut health and bioidentical hormones to mitochondrial health and ancestral living. Her latest book, How to Age, brings together the science of thriving in your second half.

A huge thank you to Zenos for sponsoring this episode. 

I have been using CellZen by Zenos as part of my cellular longevity stack because energy is not just about sleep, stress, or how busy your schedule is. It starts in your cells, especially the mitochondria that produce the energy your body runs on. As we age, mitochondrial function can slow down and cellular waste can build up, which is why CellZen brings together six of the compounds longevity research keeps coming back to: Urolithin A, NAC, Spermidine, Fisetin, MitoPrime® and Ergothioneine. It is designed to support mitochondrial function, cellular repair, antioxidant protection, and healthy ageing in one formula instead of taking multiple separate supplements.

Tim Gray speaks with Stephen Manderson, known as Professor Green, about mental health, gut health, stress, sleep, fatherhood, men's emotional avoidance, and what it actually costs the body to keep functioning while falling apart inside.

They explore why the gut and the mind cannot be separated, why men find their way to therapy only when things are already critical, and why the most regulated thing Stephen does for his own health is show up honestly for his son.

In this episode, we explore:

➡︎ Why survival mode can feel completely normal Stephen shares how growing up with pyloric stenosis, OCD, IBS, anxiety, and an unstable home environment meant stress was his baseline from birth, and how long it took to recognise that.

➡︎ How the gut and mental health create a self-perpetuating loop Tim and Stephen discuss how antibiotics, microbiome disruption, serotonin production, and psychological stress all compound each other in ways conventional medicine still tends to separate.

➡︎ Why men only seek help at crisis point Stephen reflects on his work with the British Association of Counselling and Psychotherapy and the research showing 70% of men won't seek therapy unless they are already at breaking point, and why that timing makes everything harder.

➡︎ How seemingly healthy behaviours can be avoidance Stephen explains how exercise, biohacking, and constant doing can all become sophisticated ways of not sitting with how you actually feel.

➡︎ Why safe relationships can feel boring to a dysregulated nervous system Tim and Stephen discuss how growing up with chaos means calm can feel unfamiliar, and how that shapes the partners and dynamics people unconsciously seek out.

➡︎ What fatherhood taught Stephen about emotional regulation Stephen shares how watching himself about to repeat patterns he never had modelled became the most powerful motivation to actually do the inner work.Stephen Manderson, known as Professor Green, is a BRIT Award nominated rapper, documentary maker, author, and mental health advocate. He has spoken openly about his father's suicide, his own struggles with anxiety, ADHD, autism, and complex health conditions, and has become one of the most honest voices in the conversation around men's mental health in the UK.

Tim Gray speaks with Francesca Tighinean, known online as Francesca Psychology, about connection, loneliness, dating, attraction, attachment styles, childhood wounds, and emotional safety.They explore why social connection is one of the most overlooked pillars of longevity, why safe relationships can feel boring to a nervous system used to chaos, and how to tell the difference between real love and an old pattern being activated.

In this episode, we explore:

➡︎Why connection may be one of the biggest drivers of longevity
Francesca explains why deep human connection is not just emotional, but central to health, fulfilment, resilience, and long-term wellbeing.

➡︎Why loneliness is not always about being alone
Tim and Francesca discuss why someone can be surrounded by people and still feel deeply lonely if they do not feel truly known.

➡︎How childhood wounds shape adult attraction
Francesca explains why people are often drawn to what feels familiar, even when that familiar pattern is unhealthy, unavailable, or emotionally unsafe.

➡︎Why butterflies can sometimes be anxiety
They explore why intensity, obsession, and urgency can be signs of an old wound being activated rather than genuine love.

➡︎Why safe love can feel boring
Francesca explains why a calm, steady partner may not create the same dopamine spike as a hot and cold relationship, and why that can be a green flag.

➡︎How relationships can become part of healing
Francesca and Tim discuss corrective emotional experiences, attachment, conflict, repair, and why many wounds that happen in relationships can only be fully healed in connection.

Your own biology, working the way it was designed to. Head to stemregen.co and use code TIMBIOHACKER for an exclusive discount.

Tim Gray speaks with Vishen Lakhiani, founder of Mindvalley, about why community, human connection, AI, meditation, and emotional wellbeing may be key drivers of health, longevity, and performance.They explore loneliness, HRV, social connection, the future of work, and why the people around you can shape your health more than you realise.


In this episode, we explore:
➡︎ Why community may be one of the most overlooked longevity tools
Vishen explains why human connection has such a powerful relationship with wellbeing, happiness, productivity, and resilience.

➡︎ The five levels of community
From competitive environments to mission led collaboration, Vishen breaks down how different types of culture shape human behaviour.

➡︎ Why your competitors can become your allies
Vishen and Tim discuss why the real enemy in health is not other events, brands, or leaders, but poor health itself.

➡︎ The loneliness lesson that changed Vishen’s life
After divorce and the pandemic, Vishen rebuilt his life around intentional friendship, hosting, and community.

➡︎ How AI could change the future of work
Vishen explains why AI may reduce work dramatically and why founders should start using that time for health, learning, and connection.

➡︎ Why emotional wellbeing affects performance
From team culture to positive emotion, Vishen shares why the people around you can raise or lower your state.

Dr Victoria Sampson is a biological dentist, researcher, and founder of Oralis. Her work focuses on the oral microbiome, preventative dentistry, and the connection between the mouth and systemic health.


In this episode, we explore:
 ➡︎ Why the mouth is not separate from the rest of the body
The mouth is a gateway to systemic health, and what happens there can have far-reaching consequences well beyond your teeth and gums.

➡︎ How gum disease and oral bacteria may be linked to wider health risks
The bacteria in your mouth don't stay there, and emerging research is drawing connections between oral pathogens and conditions throughout the body.

➡︎ Why bleeding gums are not normal and should not be ignored
Bleeding when you brush is a sign of inflammation, not just a dental inconvenience, and it deserves attention, not acceptance.

➡︎ How mouthwash may be disrupting your oral microbiome
That daily rinse could be wiping out the beneficial bacteria your mouth needs to stay in balance.

➡︎ What oral dysbiosis is and why it matters
When the microbial ecosystem in your mouth falls out of balance, the effects can ripple through the body in ways most people never trace back to their oral health.

➡︎ Why dentistry and medicine have been separated for so long
The split is more historical than biological, and it may be costing us more than we realise.

➡︎ The truth about fluoride, hydroxyapatite, SLS, and toothpaste ingredients
What's actually in your toothpaste, what the research says, and why the conversation is more nuanced than most people think.

➡︎ How saliva and oral microbiome testing could transform preventative health
The diagnostic tools already exist. The question is why they aren't being used more widely.

➡︎ Why optimising your body while ignoring your mouth may be a major mistake
Oral health isn't the finishing touch on a wellness routine. For many people, it may be the missing foundation.

If this episode makes one thing clear, it’s that perimenopause isn’t the beginning of decline, it’s an opportunity to take your health back with the right information and tools.


Dr. Mariza Snyder is a practitioner, author, and leading voice in women’s hormone health, with over 17 years of experience helping women navigate perimenopause and beyond. Through her widely popular podcast Energized with Dr. Mariza and her latest book The Perimenopause Revolution, she’s built a global platform dedicated to empowering women with science-backed strategies for metabolic health, hormonal balance, and long-term vitality.


Her mission is simple but powerful: to help women become the healers in their own homes through practical, accessible solutions rooted in nutrition, lifestyle, and plant-based support.


In this episode, we explore:➡︎ Why perimenopause symptoms are often misunderstood
Sleep issues, weight resistance, brain fog, and fatigue aren’t random, they’re signals of shifting hormones that can be supported, not ignored.

➡︎ The connection between hormones and metabolism
Estrogen, insulin sensitivity, and cortisol all play a critical role in how the body stores fat, uses energy, and responds to stress during midlife.

➡︎ Why women feel dismissed in traditional healthcare
Many are told their symptoms are “normal,” leaving them without real solutions, when in reality, targeted lifestyle and nutrition changes can be transformative.

➡︎ The power of nutrition and lifestyle as medicine
From blood sugar balance to anti-inflammatory foods and daily habits, small consistent inputs can dramatically shift hormonal health.

➡︎ Breaking the cycle of fatigue and burnout
Energy isn’t just about sleep, it’s about supporting the body at a cellular and hormonal level.

➡︎ Becoming your own health advocate
Understanding your body empowers you to ask better questions, seek better care, and take ownership of your long-term wellbeing.
This episode is a reminder that midlife isn’t something to survive through, it’s a phase to optimize, where the right strategies can help you feel stronger, sharper, and more energized than ever before.

This episode arrives as a reminder that many chronic health issues aren’t random, they’re the result of a body overwhelmed by toxins it can’t properly eliminate.


Dr. Christopher Shade is a chemist, researcher, and founder of Quicksilver Scientific®, specializing in mercury toxicity, environmental pollutants, and the body’s detoxification systems. With a deep background in analytical chemistry and glutathione biology, he has pioneered advanced methods for identifying and removing toxic burdens that disrupt cellular function, immune health, and neurological balance.


Through his work, Dr. Shade has developed cutting-edge diagnostics and delivery systems designed to support the body’s natural detox pathways, helping patients from all walks of life, from high performers to those with chronic illness, restore balance and resilience.


In this episode, we explore:


➡︎ Why mercury and environmental toxins are more common than you think
From seafood to air pollution to mold exposure, toxic load is a modern reality impacting energy, brain function, and immune health.


➡︎ The critical role of glutathione in detoxification
Often called the body’s master antioxidant, glutathione is central to binding and removing toxins, yet many people are depleted or unable to recycle it effectively.


➡︎ Why detox isn’t just about “removing toxins”
True detoxification is a complex, multi-phase process involving mobilization, binding, and elimination, doing it incorrectly can make symptoms worse.


➡︎ The link between toxins, inflammation, and chronic disease
Neuroinflammation, immune dysregulation, and mitochondrial dysfunction are often downstream effects of unresolved toxic burden.


➡︎ Advanced delivery systems and why they matter
How bioavailability and absorption determine whether supplements actually reach cells and support meaningful detoxification.


➡︎ Rethinking modern health through the lens of toxic load
Many unexplained symptoms, from fatigue to brain fog, may be rooted in environmental exposures that are rarely addressed in conventional care.


This episode is a deep dive into a powerful idea: healing isn’t just about adding more, it’s about removing what doesn’t belong and restoring the body’s ability to function the way it was designed to.

If this episode makes one thing clear, it’s that the symptoms many women face in midlife aren’t random, they’re signals that the body needs a new strategy.
Cynthia Thurlow is a board-certified nurse practitioner with over 25 years of clinical experience, specializing in functional nutrition and women’s health. After decades in emergency and cardiology medicine, she shifted her focus to root-cause healing, driven both by her patients’ struggles and her own personal health crisis. Today, she is a leading voice in perimenopause and menopause, helping women understand their hormones, optimize their nutrition, and reclaim their energy.

Through her podcast, books, and supplement line, Cynthia provides practical, research-backed strategies to help women navigate midlife with confidence and clarity.


In this episode, we explore:


➡︎ Why perimenopause symptoms feel so overwhelming
Sleep disruption, weight gain, fatigue, and cravings are often driven by hormonal shifts, not a lack of discipline.


➡︎ The role of nutrition in hormone balance
Food isn’t just fuel, it’s one of the most powerful tools for stabilizing blood sugar, reducing inflammation, and supporting metabolic health.


➡︎ Intermittent fasting for women
When used correctly, fasting can be a powerful tool but it must be adapted to hormonal changes and individual stress levels.


➡︎ The connection between stress, energy, and metabolism
Chronic stress and poor recovery can worsen hormonal imbalances, making fat loss and energy optimization more difficult.


➡︎ Why root-cause medicine matters
Treating symptoms without addressing underlying imbalances keeps women stuck in cycles of frustration and burnout.


➡︎ Turning adversity into purpose
Cynthia’s own health scare became the catalyst for her mission to educate and empower women to take control of their health before crisis hits.


This episode is a reminder that midlife isn’t the beginning of decline, it’s an opportunity to better understand your body, adjust your strategy, and step into a stronger, more energized version of yourself.

If this episode makes one thing clear, it’s that your genetics may set the stage, but your daily inputs determine how the story unfolds.


Gary Brecka is a human biologist, mortality researcher turned biohacker, and founder of The Ultimate Human. After spending years in the life insurance industry studying human biomarkers to predict mortality risk, Gary gained a unique perspective on the patterns that shorten or extend human life. Today, he applies that knowledge to help people optimize their biology, improve energy and cognitive performance, and dramatically extend their healthspan.


Through his work with The Ultimate Human platform and podcast, Gary shares practical, science-backed strategies designed to help people take control of their biology and unlock the vitality that already exists within them.


In this episode, we explore:


➡︎ Why biomarkers reveal the future of your health
Small signals in blood chemistry and physiology can predict disease risk years, sometimes decades before symptoms appear.


➡︎ The shift from sickness care to health optimization
Modern medicine often waits for disease to show up, while biohacking focuses on adjusting inputs early to change the trajectory entirely.


➡︎ Why genetics are not destiny
Gene expression is heavily influenced by lifestyle factors such as nutrition, sleep, stress, and environmental inputs.


➡︎ The power of understanding your own biology
When people learn how their body actually works, they gain the ability to make smarter decisions about health, energy, and longevity.


➡︎ Biohacking as a framework for modern living
From optimizing nutrition and recovery to managing stress and performance, small targeted interventions can create massive long-term impact.


➡︎ The mission behind The Ultimate Human
Gary’s work is centered on helping people realize that the energy, clarity, and vitality they’re searching for isn’t outside of them, it’s already built into their biology.


This episode is a reminder that longevity isn’t about chasing extreme interventions, it’s about understanding your body, adjusting the inputs, and giving your biology the conditions it needs to thrive.

If this episode makes one thing clear, it’s that many of our mental health struggles aren’t personal failures, they're chemistry mismatches in a world our brains weren’t designed for.


Tj Power is a neuroscientist, founder of the DOSE Lab, and bestselling author of The DOSE Effect, whose work explores how dopamine, oxytocin, serotonin, and endorphins shape our mood, motivation, connection, and resilience. After studying and lecturing at the University of Exeter, Tj recognized a growing crisis: digitally driven lifestyles were dysregulating brain chemistry at scale especially in young people.


That realization led him to create the DOSE® framework, a practical, science-backed system designed to help people rebalance their neurochemistry and thrive in the modern world.


In this episode, we explore:


➡︎ Why digital life is hijacking dopamine
Constant notifications, scrolling, and overstimulation create artificial dopamine spikes and leave us anxious, distracted, and unmotivated in real life.


➡︎ The power of oxytocin in a disconnected world
Human connection, eye contact, and shared experience regulate stress and restore emotional safety yet they’re increasingly replaced by screens.


➡︎ How serotonin builds confidence and status stability
Purpose, contribution, sunlight, and movement naturally elevate mood and self-worth without chasing validation online.


➡︎ Endorphins as nature’s stress buffer
Physical challenge, cold exposure, laughter, and effort trigger powerful biochemical shifts that build resilience.


➡︎ Rebalancing brain chemistry through simple daily habits
The DOSE framework translates complex neuroscience into small, actionable rituals that restore focus, mood, and performance.


➡︎ Why modern mental health strategies must address environment, not just emotion
We can’t meditate our way out of a chemically dysregulated lifestyle - we must change the inputs shaping our brains.


This episode is a reminder that thriving in the digital age isn’t about rejecting technology, it’s about understanding your brain chemistry well enough to work with it, not against it.
