TruAge biological age testing and advanced labs show how fast you're aging and which systems need support. Kits ship to your door or get coordinated locally.
Your provider reviews your biological age and organ-system data, then builds a personalized longevity strategy with clear priorities.
We find and address what's driving accelerated aging first, from gut and hormones to inflammation and nutrient gaps.
Your plan may include supplements, prescriptions, hormone support, and peptide or bioregulator pathways when clinically appropriate, with ongoing monitoring.
Quarterly labs, biological age reassessment, and symptom tracking help you protect your progress and keep the plan compounding as your biology changes.
Longevity is not a 30-day reset. It is a compounding process.

Most people do not fail at longevity because they are not disciplined.
Most patients work with us through a structured longevity membership model that includes:
Physician-led care. Root-cause strategy. Long-term optimization
25 years of clinical experience with a focus on hormones, gut health, chronic inflammation, women’s health, and root-cause care.
Christina brings the whole-person lens to longevity care — connecting hormones, gut health, inflammation, nutrient status, stress patterns, and symptoms that standard visits often separate.
Dr. Eric Landi, KICP
Over a decade of clinical experience with advanced functional testing, peptide therapy, metabolic optimization, and data-driven longevity protocols.
Dr. Landi helps guide HFW’s testing-first longevity strategy, peptide sequencing, mitochondrial optimization, bioregulator planning, and measurable outcome tracking.
Medical Director
20+ years in clinical practice with expertise in metabolic support, testosterone optimization, inflammation-related conditions, biological age tracking, and physician-level oversight.
Dr. Maslavi’s longevity philosophy centers on biomarker tracking, hormone and metabolic optimization, inflammation management, mitochondrial support, and proactive long-term care.
Real progress. Real support. No shame.
Jenny Pourakis
My husband has been working for years with Dr. Landi in both chiro and functional medicine. He is so happy with the results and passionate about working with Dr. Landi I had to follow! As a women in peri-menopause I experienced issues with weight gain, low energy and aging. The peptides Dr. Landi custom recommended have been a game changer. His expertise plus amazing bedside manner and caring nature are a rare blend. I highly recommend!

I have been working with Dr Landi for several months now. He is extremely knowledgeable, attentive and responsive. He actually listens which is rare in medicine these days. I’m excited to see what the results are from my protocol in a couple of months. Highly recommend his practice if you’re looking into functional medicine.
Lauren Griffith
Dr. Landi is highly knowledgeable and skilled in the field of functional medicine, but he also possesses a genuine empathy and compassion that is so often lacking in the traditional healthcare system. Dr. Landi connects to each of his patients on a personal level, works with you every step of the way, and makes you feel supported while navigating challenging health obstacles.
Kevin Heckman
I found out about the practice of Functional Dr’e last year and realized this is what I need! Finding Dr Landi so close to home was awesome. We appreciated his candor, knowledge and engaging personality. He exuded caring and interest in me and my situation. I feel he had repeatedly gone the extra mile for me so our collaboration is successful.
Book a free virtual consultation to review your symptoms, health history, longevity goals, prior labs, and whether HFW’s biological age optimization model is the right fit for you.
Your primary care doctor runs standard panels, checks for disease, and manages what’s already broken. We look at the full picture of how your biology is functioning — cellular aging, gut health, hormone metabolism, nutrient status, mitochondrial output — and build an optimization strategy before dysfunction progresses to disease. We test what most doctors don’t know to order.
TruAge + TruHealth is HFW’s biological age assessment pathway.
It helps evaluate biological age, pace of aging, and organ-system health. HFW uses this information to better understand where your body may be aging faster, which systems need support, and how to personalize your longevity strategy.
Chronological age tells us how many years you have lived.
Biological age helps show how your body may be aging internally.
Two people can be the same chronological age but have very different metabolic, inflammatory, immune, hormonal, mitochondrial, and organ-system patterns. That difference changes the strategy.
HFW does not treat longevity as a product.
We use advanced diagnostics, physician oversight, biological age testing, quarterly bloodwork, symptom tracking, root-cause correction, and protocol adjustment over time.
The model is built around long-term optimization, not isolated treatments.
Testing is strongly recommended for longevity care because it gives us the baseline needed to personalize your plan and track progress.
Your provider will help determine which tests make sense based on your symptoms, goals, medical history, risks, budget, and priorities.
The Comprehensive Longevity Workup may include TruAge + TruHealth biological age testing, comprehensive diagnostic bloodwork, genetic testing, physician review, personalized supplement planning, nutrition strategy, lifestyle guidance, and integration into your ongoing care plan.
Exact testing depends on clinical fit and provider recommendation.
Biological age testing may be done at baseline and repeated at strategic intervals depending on your goals, membership plan, budget, and provider recommendation.
Quarterly bloodwork and symptom tracking help monitor progress between deeper longevity assessments.
Longevity optimization is not a 30-day program.
Some patients notice early improvements in energy, sleep, digestion, recovery, focus, or cravings within weeks. Deeper changes in biomarkers, body composition, inflammation, hormones, mitochondrial function, and biological age may take longer.
HFW is built around quarterly optimization because the body needs time, tracking, and adjustment.
Yes, when clinically appropriate.
Peptides may be considered for recovery, mitochondrial support, metabolic function, tissue repair, immune signaling, cognitive support, gut repair, and longevity goals. They are not automatic and are not used without reviewing labs, symptoms, risks, medications, and clinical fit.
Yes, when clinically appropriate.
Bioregulators may be considered for cellular repair, organ-specific resilience, circadian rhythm, immune resilience, vascular health, and biological age optimization. HFW often uses biological age and organ-system data to guide whether bioregulators make sense.
No.
Some patients need gut restoration, hormone optimization, metabolic correction, nutrient repair, inflammation reduction, sleep improvement, or lifestyle changes first.
Peptides and bioregulators are tools. They are not the entire solution.
That is exactly why many patients come to HFW.
Standard labs often look for disease-range abnormalities. They may not fully evaluate biological age, hormone metabolites, cortisol rhythm, gut dysfunction, mitochondrial stress, nutrient depletion, food reactivity, immune patterns, or early metabolic dysfunction.
“Normal” does not always mean optimized.
No.
HFW is not a replacement for emergency care, acute care, cancer screening, urgent symptoms, or your primary care relationship.
We are a proactive, root-cause, longevity-focused partner for patients who want deeper testing, long-term tracking, and a more complete view of their health.
No. HFW is 100% telehealth.
Consultations happen virtually. At-home test kits can be shipped to you, and bloodwork can be coordinated locally when needed.
HFW operates on a cash-pay model. HSA and FSA cards are accepted where applicable, and all major credit and debit cards are accepted.
This model allows more time, deeper testing, ongoing monitoring, and proactive care that is not limited by insurance-based sick-care rules.
