How to Find a Longevity Doctor: What to Look For, What to Ask, and What to Avoid

Why Standard Medicine Falls Short#

Peter Attia calls standard medicine "Medicine 2.0" — a system designed to detect and treat overt disease. When you have a heart attack, Medicine 2.0 is extraordinarily effective. When you have the subclinical dysfunction that will cause a heart attack in 15 years, Medicine 2.0 largely misses it.

The standard annual physical in the US or UK:

• Takes 15–20 minutes
• Orders a basic metabolic panel and lipid screen
• Flags results outside pathological reference ranges
• Provides general dietary advice

What it does not do:

• Measure ApoB or Lp(a) (the lipid markers most predictive of cardiovascular risk)
• Assess insulin resistance (fasting insulin, HOMA-IR) before diabetes develops
• Evaluate functional thyroid status (free T3, reverse T3)
• Assess hormonal health comprehensively
• Discuss exercise physiology, VO₂ max, and training recommendations
• Think about your health trajectory over the next 20 years

A longevity physician — practicing what Attia calls "Medicine 3.0" — does all of these things and more.

What Longevity Medicine Actually Is#

Longevity medicine (also called precision preventive medicine, healthspan medicine, or anti-aging medicine) is characterised by:

1. Earlier intervention: Identifying risk decades before clinical disease. An ApoB of 130 mg/dL in a 40-year-old is not an emergency in Medicine 2.0 terms. In longevity medicine, it triggers immediate intervention — because 20 more years of elevated ApoB produces atherosclerotic burden that cannot be reversed.

2. Quantified assessment: Comprehensive biomarker testing, imaging, and functional testing that goes far beyond standard panels. The longevity physician builds a detailed biological picture of you, not a snapshot of your most abnormal values.

3. Evidence-informed personalization: Reading and applying primary research rather than waiting for clinical guidelines (which lag the evidence by 10–15 years). Longevity physicians are familiar with the TAME trial, the ITP rapamycin data, the Horvath clock literature, and the PREDIMED-Plus trial.

4. Long-term relationship: Rather than 15-minute annual check-ups, longevity medicine involves ongoing partnership — tracking trends, adjusting protocols, and responding to life changes.

5. Integrating all pillars: Exercise physiology, nutrition, sleep medicine, stress management, hormonal health, and pharmacological tools are all within the conversation.

Green Flags: Signs of a Good Longevity Physician#

They order the right tests without being asked:

• ApoB and Lp(a) as standard cardiovascular assessment
• Fasting insulin alongside glucose and HbA1c
• Free T3 and reverse T3 alongside TSH
• Free testosterone (not just total), DHEA-S, IGF-1
• hsCRP and homocysteine

They discuss your 20-year risk, not just current values: A good longevity physician does not look at your LDL of 3.5 mmol/L and say "that's fine." They calculate your lifetime cardiovascular exposure (ApoB × years) and discuss what level is acceptable for your goals.

They engage with exercise science: They discuss VO₂ max, zone 2 training, strength training periodisation, and can interpret your wearable data (HRV, sleep staging). They recommend specific training protocols, not just "try to get more exercise."

They are familiar with longevity-specific interventions: Rapamycin, metformin (in the longevity context), senolytics, epigenetic age testing, the fasting mimicking diet — they know these exist, have an opinion on them, and can discuss the evidence intelligently.

They acknowledge uncertainty: Good longevity physicians say "we don't know" and "the evidence is not definitive but here's my interpretation." They do not overpromise.

They engage with your bloodwork trends, not just snapshots: They track ApoB over 5 years, not just the current value. They notice that your fasting insulin has risen 30% over three years even though it is still "within normal range."

They discuss sleep, stress, and relationships: A longevity physician who does not ask about your sleep quality and social connections is missing major drivers of biological ageing.

Red Flags: Signs to Look Elsewhere#

They rely only on standard reference ranges: "Your TSH is 3.8, that's within normal" — without checking free T3, reverse T3, or discussing symptoms. Normal ranges are designed to detect pathology, not optimise health.

They dismiss your interest in longevity medicine: A physician who tells you that your interest in ApoB, epigenetic age testing, or NAD+ precursors is "not evidence-based" is behind the literature. This does not mean every patient request should be fulfilled uncritically, but a physician who is unfamiliar with the current longevity evidence is not the right partner.

They push supplements without testing: Any physician who recommends supplements without first assessing whether you are deficient is not doing personalised medicine — they are guessing.

They are not curious about your data: If you bring in your Oura sleep data, WHOOP HRV trends, and CGM glucose data and your physician is dismissive or disinterested, find someone else. These data sources provide longitudinal biological information that no clinic visit can replicate.

They do not know the ITP or TAME trial: The Intervention Testing Program and the TAME trial are the most important longevity medicine research programmes in the world. A physician practicing longevity medicine should be familiar with both.

Extreme supplement prescribing without evidence: "IV drips of NAD+ three times a week" or "ozone therapy and high-dose hormone cocktails" without comprehensive baseline testing and rationale — this is the anti-aging industry at its worst. Legitimate longevity medicine is cautious and evidence-grounded.

Where to Find Longevity Physicians#

United States#

Telehealth platforms (accessible nationwide):

• AgelessRx: One of the first telemedicine platforms explicitly for longevity medicine; physicians familiar with rapamycin, metformin, and comprehensive longevity protocols
• Marek Health: Strong in hormone optimisation and performance; telemedicine with physician oversight for comprehensive testing and protocol development
• Lifeforce: Co-founded by Tony Robbins; focuses on hormone optimisation and longevity biomarkers; physician-supervised

In-person clinics:

• Fountain Life (multiple US cities): Full longevity assessment with advanced imaging, comprehensive biomarkers, and ongoing physician partnership
• Human Longevity Inc. (San Diego): The most genomics-forward option; whole-genome sequencing integrated with clinical assessment
• Cleveland Clinic and Mayo Clinic Executive Health: The most credible academic health system option; expensive but unimpeachable quality

Independent physicians:

• Search for physicians with training from A4M (American Academy of Anti-Aging Medicine), IFM (Institute for Functional Medicine), or who use the Medicine 3.0 framework explicitly
• longevity.technology, Peter Attia's community, and biohacking forums often have physician directories

United Kingdom#

• Cleveland Clinic London: The US longevity medicine model transplanted to the UK; expensive
• Mediclinic and The Doctors Clinic Group: Private GP practices that can offer more comprehensive testing than NHS
• Numan / Manual: Telehealth focused on men's health and hormone optimisation
• Omniya Clinic (London): Longevity-focused private medicine

Europe#

• Human Longevity Labs (Austria): Epigenetic age testing and longevity protocols
• Bioniq (available in multiple European cities): Personalised supplement protocol based on comprehensive blood testing
• Private longevity clinics in major European cities increasingly offering comprehensive assessments

What Your First Appointment Should Cover#

A good longevity physician will spend the first appointment in a detailed intake:

Health history:

• Family history (cardiovascular, cancer, neurodegenerative, metabolic disease)
• Personal history including childhood adversity, chronic conditions, medications
• Lifestyle (exercise habits, sleep patterns, diet, stress levels, alcohol and substance use)

Goal setting:

• What does your longevity goal look like? Living to 90 with full physical and cognitive function? Reducing specific disease risk based on family history?
• What interventions are you already using?

Testing plan:

• A comprehensive baseline panel ordered at or after the first appointment
• Functional testing referrals (VO₂ max, DEXA, coronary calcium score if not already done)

Initial assessment:

• A preliminary risk stratification based on family history and existing data
• Identification of the 2–3 most important areas to address first

The Cost Reality#

Longevity medicine is not currently covered by standard health insurance in the US or UK. It is an out-of-pocket expense.

Realistic cost ranges:

• Telehealth consultation: $150–400/session
• Comprehensive annual blood work (direct labs): $200–650
• Physician-supervised protocol with quarterly check-ins: $2,000–5,000/year
• Fountain Life / comprehensive longevity clinic: $15,000–50,000/year
• DIY version (direct lab ordering, self-directed): $500–1,000/year

The DIY approach — ordering your own labs through Ulta Lab Tests or Inside Tracker, reading the primary literature, and supplementing appropriately — is achievable and legitimate. The physician adds: prescription access (rapamycin, hormones, thyroid medication), clinical judgment, accountability, and the ability to investigate abnormal findings appropriately.

If budget is a constraint, the priority order:

1. Comprehensive baseline bloodwork (self-pay, $200–400)
2. Find a GP willing to be a partner (some progressive GPs will engage with this conversation — they exist)
3. Single telehealth consultation with a longevity physician ($200–400) for protocol review and prescription assessment if needed
4. Ongoing self-management with annual comprehensive bloodwork and annual physician check-in
