Feel Better. Function Better. Age Better.

At Longevous Youth Clinic, we look beyond isolated symptoms to understand how hormones, metabolism, nutrition, sleep, stress, lifestyle and medical history may be affecting how you feel. Your care begins with a comprehensive evaluation and an individualized plan designed around your health goals.

When You Know Something Has Changed

Fatigue, weight changes, poor sleep, brain fog, hot flashes, low libido, digestive symptoms, loss of strength and reduced energy can have more than one contributor. Our role is to evaluate the bigger picture, identify modifiable factors and build a practical medical plan for you.

Six Core Programs

Longevous 360™ Functional Medicine

Longevous 360™ is our flagship whole-person program for patients who want a comprehensive view of their health. We evaluate symptoms in context — including medical history, medications, nutrition, activity, sleep, stress, hormonal factors and metabolic health — then build a prioritized plan.

Menopause & Men's Hormone Optimization

Hormonal changes can affect sleep, energy, sexual health, mood, body composition and quality of life. We provide individualized evaluation for women in perimenopause or menopause and for men with symptoms that may warrant hormone assessment.

Metabolic Reset & Medical Weight Management

Metabolic Reset is designed for sustainable weight and metabolic health rather than a medication-only approach. We evaluate the factors influencing weight, appetite, body composition and cardiometabolic risk, then create an individualized plan.

Energy, Stress & Sleep Optimization

Low energy, poor sleep and brain fog are common but nonspecific. This program uses a structured medical assessment to look for modifiable contributors rather than assuming one hormone, vitamin or supplement is responsible.

Healthy Aging & Longevity Assessment

Healthy aging is not a promise to stop aging. It is a proactive approach to preserving function, reducing modifiable risk and supporting quality of life. This program organizes your current health data into a practical longevity strategy.

Gut Health & Inflammation

Digestive symptoms can arise from diet, medications, constipation, food intolerance, functional gastrointestinal disorders and medical conditions that require evaluation. Our approach begins with history and red-flag screening, then uses targeted testing and treatment when appropriate.

What Makes Our Approach Different

Whole-person assessment

Symptoms are considered in the context of medical history, lifestyle and risk factors.

Clinician-led care

Evaluation and treatment decisions are medically supervised.

Targeted testing

Testing is selected for a clinical reason, not automatically ordered as a package.

Integrated planning

Nutrition, movement, sleep and stress strategies can complement conventional medical treatment.

Ongoing follow-up

Progress is reviewed and plans are adjusted when needed.

Testing Based on Your Individual Needs

Depending on your history and symptoms, your evaluation may include conventional laboratory testing and selected specialty testing. Examples may include metabolic markers, thyroid testing, hormone evaluation, nutritional markers, cardiometabolic risk assessment and selected functional testing when clinically appropriate.

Functional & Longevity Medicine From Home

Selected consultations and follow-up visits are available by telemedicine for eligible Florida patients. Telemedicine may be appropriate for functional medicine follow-up, hormone and metabolic care, laboratory review, weight-management follow-up and longevity planning. Some concerns require an in-person examination or testing.

Look as Vibrant as You Feel

For patients who also want aesthetic care, Longevous Youth Clinic offers a separate menu of clinician-guided facial rejuvenation and skin-quality services. Aesthetic treatment is personalized and remains distinct from the six core medical programs.
