RWDr Ross WalkerCardiologist · Australia

One of Australia's longest-running preventive-medicine media figures, advocating non-invasive cardiac/arterial screening as a longevity tool.

Practising cardiologist (~40 years), Sydney Heart Health Clinic; President, Gut Foundation of Australia. Author of seven preventive-cardiology books.

One of Australia's longest-running preventive-medicine media figures, advocating non-invasive cardiac/arterial screening as a longevity tool.

  1. Get coronary calcium scoring / arterial screening for early cardiovascular risk detection.
  2. Eat omega-3-rich foods (salmon, walnuts); consider turmeric/curcumin for cardiac inflammation.
  3. Consider Ubiquinol (active CoQ10) to support LDL cholesterol, especially alongside statins.
  4. Actively manage stress — chronic cortisol/adrenaline elevation raises cardiac risk.
  5. Maintain strong social/friendship networks, linked to lower heart disease risk.
  6. Exercise at least 30 minutes daily, prioritising cardio.
DKDr Damian KristofChiropractor · Australia

Runs an annual "Blue Zones" trip to Ikaria, Greece, and frames longevity around slowing down, community and purpose rather than optimisation.

Chiropractor, Sandringham VIC; co-host, The Wellness Guys' Show and 100 Not Out (interviews with centenarians on ageing well).

Runs an annual "Blue Zones" trip to Ikaria, Greece, and frames longevity around slowing down, community and purpose rather than optimisation.

  1. Slow down — avoid over-scheduling; take an unhurried approach to meals and daily life.
  2. Prioritise community and a sense of purpose, especially in older age.
  3. Eat seasonally and locally; minimise processed/imported food.
  4. Practice daily gratitude rituals.
  5. Walk ~30 minutes every day.
  6. Address stress across three fronts: physical (exercise), chemical (reduce household toxin exposure), emotional (mindfulness, massage, acupuncture).
DLProf. David Le Couteur, AOResearcher · Australia

One of Australia's most-cited aging researchers — geroscience and the relationship between dietary macronutrient ratios and healthy lifespan.

Professor of Geriatric Medicine, University of Sydney & Concord Repatriation General Hospital; Director, Centre for Education and Research on Ageing. 300+ publications.

One of Australia's most-cited aging researchers — geroscience and the relationship between dietary macronutrient ratios (protein vs. carbohydrate) and healthy lifespan.

No publicised "top tips" list — he's a bench/clinical researcher, not a media personality. His research (e.g. the "Okinawan ratio" of protein to carbohydrate) suggests moderate protein and higher-quality carbohydrates may support healthy aging, but he's on record cautioning that human evidence for turning this into individual dietary advice "isn't clear-cut." Cite his findings, not a personal regimen.
LWA/Prof. Lindsay WuResearcher · Australia

A leading Australian voice on NAD+ biology and its role in aging and fertility decline — the same pathway David Sinclair champions, approached with more caution.

Associate Professor, UNSW Sydney; leads the Wu Group / Laboratory for Ageing Research. NHMRC-funded continuously since 2015.

A leading Australian voice on NAD+ biology and its role in aging and fertility decline — the same pathway underlying David Sinclair's public advocacy, approached with more caution.

No verified public "top tips" content — his commentary (e.g. in The Conversation) is deliberately measured and skeptical of overhyped longevity claims, rather than a personal-advice list. Do not attribute supplement or lifestyle recommendations to him beyond his NAD+ research interest.
MHMarc HermannFounder · Australia

Built Everlab after his father died suddenly of a heart attack in his mid-40s with no warning signs — early biomarker detection plus structured coaching, not supplements.

Founder & CEO, Everlab — Melbourne-based preventive-health platform (clinics in Sydney, Melbourne, Adelaide); raised A$65M in 2026 at ~A$500M valuation. Previously founded Foodspring (sold to Mars, 2019).

Built Everlab after his father died suddenly of a heart attack in his mid-40s with no warning signs — positions the company around early biomarker detection plus structured lifestyle coaching, not supplements.

Primarily a company/founder profile rather than a personal-tips source — his public messaging centres on Everlab's institutional thesis (comprehensive biomarker testing, early detection, fat-loss/muscle-gain coaching), not individual actionable tips. Useful as a competitor/ecosystem reference for this project.
CNDr Christian NefzgerResearcher · Australia

Studies transcriptional/epigenetic shifts across 45+ cell types linking developmental maturation to aging — a headline finding implicates the transcription factor AP-1.

Group Leader, Cellular Reprogramming and Ageing Laboratory, Institute for Molecular Bioscience, University of Queensland.

Studies transcriptional/epigenetic shifts across 45+ cell types linking developmental maturation to aging — a headline finding implicates the transcription factor AP-1.

Pure molecular/cell-biology research, no public "top tips" content. Included only as a research-credibility citation (e.g. "IMB's ageing research group"), not as a source of consumer-facing advice.
NSDr Norman SwanBroadcaster · Australia

Widely described as Australia's most trusted doctor — decades spent translating research for a mass AU audience, careful to separate evidence from wasteful advice.

Physician and broadcaster; long-time host, ABC Radio National's Health Report. Author of So You Want to Live Younger Longer? (2022).

Widely described as Australia's most trusted doctor — decades spent translating research for a mass AU audience, careful to separate evidence-based interventions from wasteful ones.

  1. Focus on food quality and total calorie intake, not fad diets.
  2. Moderate alcohol only; minimise saturated fat; prioritise dietary diversity.
  3. Favour Mediterranean-style eating.
  4. Prioritise sleep quality over duration — waking refreshed matters more than a specific hour count.
  5. Genetics matter less than lifestyle for most people.
  6. Tailor health priorities by decade of life rather than one-size-fits-all advice.

PAPeter Attia, MDPhysician · Global

"Medicine 3.0" — train now for a Centenarian Decathlon against the four chronic-disease killers, instead of waiting to treat disease after it appears.

Founder, Early Medical; author of Outlive (2023); host, The Peter Attia Drive. Stanford MD, Johns Hopkins surgical residency, NCI research fellow.

"Medicine 3.0" — train now for a Centenarian Decathlon against the four chronic-disease killers, instead of waiting to treat disease after it appears.

  1. Train all four pillars: stability, strength, Zone 2 aerobic base, and Zone 5 (VO2 max) work.
  2. Do regular Zone 2 cardio — sustained output kept under roughly 2 mmol/L blood lactate.
  3. Track VO2 max directly; cites moving out of the bottom quartile as linked to ~70% lower all-cause mortality risk.
  4. Prioritise resistance training to protect muscle mass and bone density decades ahead.
  5. Push protein intake above standard RDA levels (exact target varies by his own account — verify before citing a number).
  6. Manage apoB / LDL particle number aggressively, not just total cholesterol.
  7. Discusses rapamycin and metformin as longevity levers, but stops short of blanket-endorsing either.
AHAndrew Huberman, PhDAcademic · Global

Turns neuroscience into specific daily protocols — light, temperature, breath, supplements — for sleep, focus and stress resilience.

Tenured professor, Neurobiology & Ophthalmology, Stanford School of Medicine; host, Huberman Lab podcast.

Turns neuroscience into specific daily protocols — light, temperature, breath, supplements — for sleep, focus and stress resilience.

  1. Get 10–15 minutes of outdoor light within the first hour of waking, no sunglasses, to anchor circadian rhythm.
  2. Delay caffeine 90–120 minutes after waking to work with cortisol/adenosine dynamics.
  3. Use NSDR (non-sleep deep rest), ~10–20 minutes, to recover alertness after poor sleep.
  4. Combine cold exposure (1–3 min) and sauna a few times weekly for resilience and recovery.
  5. Split weekly training: ~3 resistance + 3 cardio sessions (one long Zone 2, one moderate, one HIIT).
  6. Personal stack (his own, not universal): magnesium L-threonate, vitamin D3, EPA omega-3, creatine, apigenin + L-theanine before bed.
  7. Keep the bedroom dark, cool and device-free; avoid bright light in the evening.
DSDavid Sinclair, PhD, AOAcademic · Global — AU-born

Leading academic voice for "aging as a treatable disease," centred on sirtuins, NAD+ decline and an epigenetic theory of aging — popularised NMN and resveratrol.

Professor of Genetics, Harvard Medical School; co-director, Paul F. Glenn Center for Biology of Aging Research. Born and raised in Sydney; dual AU/US citizen. Author of Lifespan (2019).

Leading academic voice for "aging as a treatable disease," centred on sirtuins, NAD+ decline and an epigenetic theory of aging — popularised NMN and resveratrol.

  1. NMN, reportedly ~1 g/day, to raise NAD+ levels.
  2. Resveratrol, reportedly ~1 g/day, taken with a fat source for absorption.
  3. Metformin, reportedly ~800 mg/day (evening) — off-label and scientifically contested.
  4. Vitamin D3 (reportedly 4,000–5,000 IU) and K2 (reportedly 180–360 mcg).
  5. Low-dose aspirin, reportedly ~81 mg/day.
  6. Spermidine, quercetin and fisetin as senolytic/autophagy-supporting compounds.
  7. Intermittent fasting, minimal sugar and red meat, and regular exercise as general lifestyle notes.
RPRhonda Patrick, PhDPhD · Global

A research-literature translator rather than a clinician — sources primary papers closely, and is explicit that her routine is personal, not a prescription.

PhD, biomedical science (mitochondrial metabolism/cancer, St. Jude); postdoc under Bruce Ames (micronutrients, inflammation). Founder, FoundMyFitness.

A research-literature translator rather than a clinician — sources primary papers closely, and is explicit that her routine is personal, not a prescription.

  1. Regular sauna use, citing Finnish cohort studies linking frequency to lower cardiovascular and all-cause mortality.
  2. Creatine monohydrate, ~5 g on light days up to ~10 g/day, higher during travel or sleep loss.
  3. Sulforaphane / broccoli-sprout extract for Nrf2 pathway activation.
  4. Omega-3 fish oil, ~1 g with breakfast and again in the evening.
  5. Vitamin D3 (~2,000 IU) with K2 in the evening; magnesium glycinate (~125 mg) for sleep.
  6. Melatonin, ~3 mg, in the evening.
Among the most scrupulous of this group about sourcing primary literature and flagging evidence strength; states no financial ties to the brands she uses.
VLValter Longo, PhDAcademic · Global

Leading researcher on fasting-mimicking diets and their effects on regeneration and metabolic health, advocating a largely plant-based, moderate-protein diet.

Professor of Gerontology, USC Leonard Davis School; Director, USC Longevity Institute. Author of The Longevity Diet (2018); co-founder, L-Nutra (ProLon).

Leading researcher on fasting-mimicking diets and their effects on regeneration and metabolic health, advocating a largely plant-based, moderate-protein diet.

  1. Largely vegan diet plus fish 2–3×/week (salmon, anchovies, sardines, cod, shellfish).
  2. Moderate protein under 65: ~0.31–0.36 g per lb bodyweight/day; increase somewhat after 65 to counter muscle loss.
  3. Get protein mainly from legumes rather than red meat; ~3 tbsp olive oil and ~1 oz nuts daily.
  4. Confine eating to a ~12-hour window; avoid food in the 3–4 hours before bed.
  5. Periodic 5-day Fasting Mimicking Diet cycles (low-calorie, plant-based, mimics water fasting).
  6. Minimise sugar and saturated fat; maximise whole grains and vegetables.
MWMatthew Walker, PhDAcademic · Global

The most credentialed public voice specifically on sleep — treats sleep as the foundational, most under-rated pillar of long-term health.

Professor of Neuroscience & Psychology, UC Berkeley; director, Center for Human Sleep Science. Author of Why We Sleep (2017).

The most credentialed public voice specifically on sleep — treats sleep as the foundational, most under-rated pillar of long-term health.

  1. Keep a consistent sleep/wake schedule, seven days a week — his single highest-priority tip.
  2. Exercise 30+ minutes most days, but not within 2–3 hours of bedtime.
  3. Cut caffeine and nicotine in the afternoon/evening (caffeine's ~5–6 hr half-life).
  4. Avoid alcohol before bed — it fragments sleep and suppresses REM even as it eases falling asleep.
  5. Get 30+ minutes of morning sunlight; avoid bright/blue light in the evening.
  6. Keep the bedroom cool (~18°C), dark and gadget-free; a hot shower before bed helps trigger sleepiness.
  7. Aim for 7–9 hours nightly, adjusted for individual need.
Among the least commercially entangled on this list — no supplement line under his name.

The most extreme, best-resourced public self-experiment in rejuvenation, with diet, sleep and biomarkers algorithmically tracked toward an explicit goal to "not die."

Founder, Braintree (acquired Venmo, sold to PayPal for $800M). Runs "Project Blueprint" — a self-funded, self-experimentation anti-aging regimen — since 2021. Not a physician or scientist.

The most extreme, best-resourced public self-experiment in rejuvenation, with diet, sleep and biomarkers algorithmically tracked toward an explicit goal to "not die."

  1. Strict sleep schedule: bedtime ~8:30pm, wake ~5am; screens off 60 min before bed; room at 18–21°C.
  2. Time-restricted eating, stopping around noon each day; ~2,250 kcal/day with ~10% caloric restriction.
  3. Signature "Super Veggie" meal: black lentils, broccoli, cauliflower, mushrooms, garlic, ginger, hemp seeds.
  4. ~6 hours/week exercise: 3 strength + 3 cardio sessions, plus mobility work.
  5. Daily dry sauna (~93°C) for 20 minutes, plus red/near-infrared light therapy.
  6. Large supplement/drug stack: creatine (~5–7.5 g), EPA/DHA, collagen peptides, plus repurposed prescription drugs — metformin (cycled), acarbose, and a PCSK9 inhibitor (Repatha) for cholesterol — physician-supervised and disclosed publicly, not general recommendations.
  7. Extensive monitoring: quarterly bloodwork, annual full-body MRI, continuous glucose monitoring.
MHMark Hyman, MDPhysician · Global

Popularised "functional medicine" — root-cause, systems-based diagnosis with heavy emphasis on nutrition and personalised lab testing.

CMO & co-founder, Function Health; senior adviser, Cleveland Clinic Center for Functional Medicine (founder). Author of Food: What the Heck Should I Eat? and others.

Popularised "functional medicine" — root-cause, systems-based diagnosis with heavy emphasis on nutrition and personalised lab testing.

  1. Minimise sugar and refined carbohydrates first, above all else.
  2. Fill more than half the plate with colourful, non-starchy vegetables at every meal.
  3. Favour healthy fats — omega-3s, olive oil, avocado, fatty fish — over industrial seed oils.
  4. Treat meat as a "condiment" (4–6 oz portions), not the centre of the plate.
  5. Minimise dairy and gluten for most people; choose gluten-free whole grains in modest portions.
  6. Use extensive personal biomarker testing (100+ markers) to individualise nutrition, rather than one-size-fits-all rules.
DBDan BuettnerJournalist · Global

Popularised the idea that longevity comes mostly from lifestyle and environment, distilled from the "Blue Zones" into nine "Power" principles.

National Geographic Fellow; coined "Blue Zones" after a 2004–05 NatGeo research collaboration. Author of the Blue Zones book series. Not a physician or scientist.

Popularised the idea that longevity comes mostly from lifestyle and environment — diet, movement, purpose, social structure — distilled into nine "Power" principles.

  1. Move naturally — build low-intensity activity (gardening, walking, housework) into daily life.
  2. Keep a clear sense of purpose ("ikigai" in Okinawa).
  3. Downshift daily to manage stress — prayer, napping, social time.
  4. "Hara Hachi Bu" — stop eating at about 80% fullness.
  5. "Plant Slant" — build meals around beans and plants; meat only a few times a month.
  6. Belong to a faith-based or other regular community.
  7. Maintain a social circle that reinforces healthy habits.

Reframes skeletal muscle, not fat tissue, as the central organ of long-term metabolic health — "under-muscled" as the more overlooked driver of decline.

Board-certified osteopathic physician; founder, "Muscle-Centric Medicine®"; author of Forever Strong (2023).

Reframes skeletal muscle, not fat tissue, as the central organ of long-term metabolic health — "under-muscled" as the more overlooked driver of decline.

  1. Distribute protein evenly across the day — a commonly cited target of ~30 g per meal.
  2. Prioritise resistance training as the primary form of exercise for healthspan, not just cardio.
  3. Treat skeletal muscle as an endocrine organ central to metabolic health, not an aesthetic concern.
  4. Especially protect protein intake and resistance training during weight loss, to avoid losing muscle with fat.
  5. Favour protein-forward breakfasts over carbohydrate-heavy ones.
Core message is broadly consistent with mainstream exercise/nutrition science; specific figures (e.g. "30g") are her own practical heuristic, not an official guideline.

Supplement & vitamin consensus, plainly counted

Lifestyle habits excluded — this counts only pills and powders. Of the 17 people above, just five publish an explicit personal supplement stack (Huberman, Sinclair, Rhonda Patrick, Ross Walker, Bryan Johnson); everyone else is lifestyle- or food-first, or gives no personal regimen. Ranked by how many of those five independently recommend it.

Vitamin D3 3 / 5
Omega-3 (fish oil) 3 / 5
Huberman, Patrick, Bryan Johnson — Ross Walker recommends omega-3-rich food, not a supplement, so counted separately
Creatine 3 / 5
Vitamin K2 2 / 5
Always paired with D3, by Sinclair and Patrick
Magnesium 2 / 5
Huberman (L-threonate), Patrick (glycinate) — different forms, same mineral

Single-mention, below the consensus bar: CoQ10/Ubiquinol and turmeric/curcumin (Ross Walker only); NMN, resveratrol, and spermidine/quercetin/fisetin (Sinclair only); melatonin and sulforaphane (Patrick only); apigenin and L-theanine (Huberman only); collagen peptides (Bryan Johnson only).

Not a supplement — off-label prescription drugs: metformin is the closest thing to a cross-cutting pick, but it's a prescription drug, not an OTC supplement, and remains scientifically contested for this use — Sinclair and Bryan Johnson both take it personally, and Attia discusses it without endorsing it. Johnson separately takes acarbose and a PCSK9 inhibitor, both physician-supervised and off-label.

Straight answers, sourced

How do you decide who's listed here, and how is it checked?
This page catalogues what named public figures have themselves said, written or published — it is not medical advice, and inclusion here is not an endorsement of any product, supplement or protocol by this platform. Dosages and protocols are self-reported by each person, drawn from their own books, podcasts, interviews and sites, not peer-reviewed clinical guidelines — where a specific figure couldn't be verified, that's noted rather than guessed. This platform has no commercial relationship with anyone listed here. Consult a qualified Australian health professional before acting on anything above. Compiled via web search, 5 September 2026 — verify any figure directly against primary sources before it's used elsewhere.
Does this platform endorse any of these recommendations?
No. This page catalogues what named public figures have said publicly about longevity — it's a factual directory, not medical advice, and being listed isn't an endorsement of a product, supplement or protocol.
Which supplement has the most agreement among these experts?
Of the five people here who publish a personal supplement stack, vitamin D3, omega-3 fish oil and creatine each get three independent recommendations — the highest agreement found. Everything more exotic (NMN, resveratrol, CoQ10) is a single person's pick.
