Medicine That Treats the Whole Person.
Physician-led integrative and functional medicine — combining advanced diagnostic testing with evidence-based therapies to find and fix the root cause of your symptoms.
What Is Integrative Medicine?
Integrative medicine is a patient-centered approach that combines the best of conventional medicine with evidence-based complementary therapies. Rather than managing symptoms in isolation, integrative medicine seeks to understand the underlying imbalances — metabolic, hormonal, nutritional, inflammatory, or environmental — that drive chronic illness and suboptimal health.
At Infusion Center of NJ, Dr. Jeffrey A. Weiss, MD brings over two decades of clinical experience to every integrative consultation. His approach begins with listening — a thorough review of your history, symptoms, lifestyle, and goals — followed by advanced functional lab testing to identify what conventional panels often miss. Treatment is then built around your specific findings, not a generic protocol.
Root-Cause Diagnosis First
Most patients arrive having been told their labs are 'normal' — yet they still feel unwell. Dr. Weiss goes deeper.
Comprehensive Intake
Your first visit is a deep-dive conversation. Dr. Weiss reviews your full medical history, prior lab work, medications, diet, sleep, stress, and symptoms in detail — taking the time that conventional appointments rarely allow.
Advanced Functional Testing
Standard blood panels test for disease. Functional labs test for optimal function. Dr. Weiss orders the tests that reveal micronutrient deficiencies, hormonal imbalances, inflammatory markers, gut dysfunction, toxic burden, and metabolic inefficiencies that standard care overlooks.
Personalized Treatment Plan
Once your results are in, Dr. Weiss presents a clear, prioritized treatment plan — explaining what your labs show, why it matters, and exactly what we will do about it. No guesswork, no generic protocols.
Ongoing Partnership
Integrative medicine is not a one-time visit. Dr. Weiss monitors your progress, adjusts your protocol as your health evolves, and remains your partner in long-term wellness — not just a provider you see when something goes wrong.
Testing That Goes Beyond the Standard Panel
Conventional labs are designed to detect disease. Functional labs are designed to detect dysfunction — the metabolic, hormonal, and nutritional imbalances that cause symptoms long before a diagnosis is warranted. Dr. Weiss uses advanced testing to build a precise picture of your biology.
Integrative Services
A comprehensive suite of diagnostic and therapeutic services — all physician-designed and supervised.
Functional Lab Testing
Advanced panels beyond standard bloodwork — micronutrient levels, organic acids, comprehensive hormone panels, inflammatory markers, gut microbiome analysis, heavy metal testing, and more. We test for optimal function, not just the absence of disease.
Hormone Optimization
Comprehensive evaluation and balancing of thyroid, adrenal, sex hormones (testosterone, estrogen, progesterone), and cortisol. Bioidentical hormone therapy when indicated, guided by detailed lab work and symptom review.
Nutritional Medicine
Personalized nutrition protocols based on your metabolic profile, food sensitivities, and health goals. Therapeutic supplementation guided by functional lab findings — not guesswork.
IV Micronutrient Therapy
Targeted intravenous infusions — vitamin C, Myers' Cocktail, glutathione, NAD+, and custom formulations — to rapidly correct deficiencies and support cellular function at concentrations oral supplements cannot achieve.
Gut Health & Microbiome
Comprehensive stool analysis, SIBO testing, and leaky gut assessment. Therapeutic protocols to restore gut integrity, rebalance the microbiome, and address the gut-immune-brain axis.
Detoxification Support
Physician-supervised protocols to support the body's natural detoxification pathways — addressing toxic burden from heavy metals, environmental chemicals, and metabolic waste that contribute to chronic illness.
Who We Help
Integrative medicine is particularly effective for patients with chronic, complex, or unexplained conditions that have not responded fully to conventional care.
