Longevity Medicine
Medically reviewed by Dr. Patricia Sitnitsky, M.D. · Last reviewed July 2026
Avita MD offers longevity medicine services at our clinics in Los Altos, Mountain View, and Los Gatos. We use advanced biomarker testing, metabolic evaluation, hormone optimization, and evidence-based interventions to help you extend your healthspan and address the root causes of aging before they lead to disease. On-site phlebotomy and EKG are available at all locations.
We are a physician-owned practice with 12 providers, same-day appointment availability, and more than 890+ five-star Google reviews. We accept Medicare, most major PPO plans, and HMO plans.
What Longevity Medicine Addresses
The diseases that most often shorten or diminish life, including heart disease, cancer, diabetes, and neurodegenerative conditions, do not appear overnight. They develop over decades, driven by processes that are measurable and, in many cases, modifiable. Our work centers on cardiovascular, brain, metabolic, immune, and mitochondrial health, and longevity medicine focuses on these underlying drivers:
- Chronic inflammation: Low-grade inflammation accelerates atherosclerosis, joint degeneration, and cellular damage. We measure hs-CRP, homocysteine, and other inflammatory markers.
- Metabolic dysfunction: Insulin resistance and impaired glucose metabolism are precursors to diabetes, fatty liver disease, and cardiovascular disease. We test fasting insulin, HbA1c, and advanced metabolic markers.
- Hormonal decline: Falling levels of testosterone, estrogen, thyroid hormones, and DHEA affect energy, cognition, body composition, and disease risk.
- Cardiovascular risk: Advanced lipid testing, lipoprotein(a), and cardiac imaging reveal risk that standard cholesterol panels miss.
- Nutrient deficiencies: Low levels of vitamin D, B12, magnesium, and other nutrients impair immune function, energy production, and bone health.
Our Approach
Comprehensive Baseline Testing
Your first visit includes an in-depth health history and an expanded blood panel covering over 60 biomarkers. This is similar to our executive wellness exam and serves as your biological baseline. We test metabolic function, hormones, inflammation including hs-CRP and homocysteine, cardiovascular risk, nutrient status, organ function, and more. We also offer genetic and epigenetic testing through 3x4 Genetics to understand how your biology shapes cardiovascular, brain, metabolic, immune, and mitochondrial health. On-site EKG is available, and we can coordinate advanced imaging through our referral network when indicated.
Trend Analysis and Longitudinal Tracking
A single set of labs is a snapshot. What matters more is the trajectory. We track your biomarkers over months and years, identifying patterns that indicate accelerating risk even when individual numbers still fall within "normal" ranges. A fasting glucose that has risen from 85 to 98 over three years is not yet pre-diabetic, yet it tells a story we can act on.
Personalized Intervention Plan
Based on your results, we build a plan that may include:
- Targeted nutrition and exercise recommendations based on your metabolic profile
- Sleep optimization strategies
- Hormone optimization, including bioidentical hormone replacement therapy (BHRT) and testosterone therapy when labs support it
- NAD+ therapy and IV infusions
- Supplement protocols for documented deficiencies
- Cardiovascular risk reduction through medication, lifestyle, or both
- Referrals for advanced testing or specialist consultation
Regular Reassessment
We schedule follow-up labs at six-month intervals and a comprehensive reassessment annually. This allows us to measure whether interventions are working, adjust your plan, and catch new developments early.
Who Benefits from Longevity Medicine
Longevity medicine is relevant for anyone who wants to be proactive about aging. It is especially valuable if you:
- Have a family history of heart disease, cancer, diabetes, or Alzheimer's disease
- Feel healthy and want to stay that way for decades to come
- Have been told your labs are "normal" and want to dig deeper
- Are interested in optimizing energy, body composition, and cognitive performance
- Want a physician who tracks your data over years, not just episode to episode
Schedule Your Longevity Evaluation

Frequently Asked Questions About Longevity Medicine
What is longevity medicine?
Longevity medicine focuses on extending your healthspan, the number of years you live in good health, not just your lifespan. At Avita MD, this means identifying and addressing the biological processes that drive aging, including inflammation, metabolic dysfunction, hormonal decline, and cellular damage, before they cause disease.
How is longevity medicine different from preventive care?
Standard preventive care screens for diseases that have already developed or are imminent. Longevity medicine at Avita MD goes further by testing deeper biomarkers, tracking trends over time, and intervening at the earliest signs of biological aging. The goal is to prevent the conditions that preventive care typically catches later.
What testing does a longevity evaluation include?
A longevity evaluation at Avita MD typically includes an expanded metabolic panel, advanced lipid analysis, inflammatory markers (hs-CRP, homocysteine), hormone profiling, insulin and glucose metabolism, nutrient levels, thyroid function, and cardiovascular risk markers. We also offer genetic and epigenetic testing through 3x4 Genetics. Depending on your goals, we may also recommend body composition analysis or advanced imaging.
Do you offer genetic and epigenetic testing for longevity?
Yes. Avita MD offers genetic and epigenetic testing through 3x4 Genetics as part of a longevity evaluation. These results reveal how your individual biology influences cardiovascular, brain, metabolic, immune, and mitochondrial health, and they help us build a prevention plan matched to your genetics rather than population averages.
What treatments are available through longevity medicine at Avita MD?
Beyond nutrition, exercise, and supplement protocols, Avita MD offers NAD+ therapy and IV infusions along with hormone optimization, including bioidentical hormone replacement therapy (BHRT) and testosterone therapy when labs support it. Your provider recommends treatments based on your biomarkers and your goals across cardiovascular, brain, metabolic, immune, and mitochondrial health.
Do I need to be sick to benefit from longevity medicine?
No. Most patients who come to Avita MD for longevity medicine feel healthy and want to stay that way. The value is in catching problems years before symptoms appear and making evidence-based changes to slow biological aging.
Does insurance cover longevity medicine?
Many components of a longevity evaluation are covered under preventive care benefits, including annual physicals, blood work, and standard screenings. Some advanced testing may be self-pay. Avita MD will let you know about any out-of-pocket costs before ordering tests.
How often should I have a longevity evaluation?
Most patients at Avita MD do a comprehensive longevity evaluation annually, with targeted follow-up labs every six months. If you are making significant lifestyle or treatment changes, more frequent monitoring helps track progress and adjust your plan.
