Anti-Aging and Longevity Medicine in Los Angeles
Anti-aging medicine represents a paradigm shift in healthcare—from treating disease after it develops to detecting, preventing, and reversing age-related decline before it impacts your quality of life. Our approach combines advanced diagnostics, functional medicine principles, and evidence-based interventions to optimize your healthspan and extend your years of vitality.
Dr. Farshid Sam Rahbar is fellowship-trained and board-certified in anti-aging and regenerative medicine. He specializes in applying anti-aging principles specifically to gastrointestinal health, microbiome optimization, and nutritional longevity. Because digestive health is foundational to all aspects of aging, our integrated anti-aging approach addresses the gut-brain-immune axis while optimizing nutrient absorption, hormone balance, and cellular regeneration.

Anti-aging medicine is a clinical science designed to reduce the negative effects of aging through early detection, prevention, and reversal of age-related diseases and disabilities. Rather than accepting decline as inevitable, anti-aging practitioners apply innovative diagnostic and therapeutic tools to maintain optimal function throughout the lifespan.
The foundation of anti-aging medicine includes:
- Early Detection – Identifying disease risk factors and subclinical pathology before symptoms appear
- Prevention – Implementing lifestyle, nutritional, and medical interventions to halt or slow disease progression
- Reversal – Using targeted protocols to actually improve markers of aging and restore physiologic function
- Optimization – Supporting performance, cognition, energy, and wellness beyond simply “not being sick”
Unlike conventional medicine, which primarily addresses symptomatic disease, anti-aging medicine takes a systems-based approach to maintaining health, vitality, and longevity across all domains of human function.
The American Academy of Anti-Aging Medicine
The American Academy of Anti-Aging Medicine (A4M) is a non-profit medical society dedicated to advancing the science of human aging and longevity. Founded on principles of evidence-based medicine, A4M works to:
- Educate physicians and healthcare practitioners about anti-aging medicine principles and applications
- Develop evidence-based tools and techniques for assessing and optimizing biological age
- Establish best practices and clinical guidelines for anti-aging interventions
- Fund and promote high-quality research into aging processes and longevity interventions
- Advocate for anti-aging medicine as a legitimate and essential medical discipline
- Support physicians worldwide who integrate anti-aging principles into their clinical practice
At LA Integrative Gastroenterology & Nutrition, we apply A4M principles specifically to gastrointestinal health, recognizing that a healthy digestive system is the cornerstone of successful aging.
Anti-Aging Strategies We Employ
Our anti-aging approach integrates multiple interventions:
Comprehensive Analytical Assessment – We measure biological markers including inflammatory cytokines, oxidative stress, micronutrient status, microbiome composition, and hormone levels to determine your true biological age independent of chronologic age.
Oxidative Stress Management – We assess your free radical burden and antioxidant capacity, then implement targeted interventions to restore cellular balance and reduce aging acceleration.
Inflammation Control – Chronic inflammation is the primary driver of age-related disease. We identify and address inflammatory triggers through diet, supplementation, and lifestyle modification.
Customized Nutrition – Personalized nutritional protocols optimize nutrient absorption, support cellular regeneration, and reduce disease risk.
Condition Management – Treating existing conditions (SIBO, dysbiosis, malabsorption, food sensitivities) prevents premature aging and supports health optimization.
Advanced Diagnostics – Procedures like colonoscopy, endoscopy, and specialized testing identify early pathology before it progresses to symptomatic disease.
Why Digestive Health Is Critical for Anti-Aging
The gut is often called the “second brain” and the foundation of health. Here’s why optimizing digestive function is essential for successful aging:
Nutrient Absorption – A healthy digestive tract maximizes absorption of essential nutrients required for cellular function, energy production, immune function, and tissue regeneration. Poor digestion leads to deficiencies that accelerate aging.
Microbiome Balance – Your gut bacteria produce short-chain fatty acids, vitamin K, B vitamins, and other compounds essential for immune function, brain health, and metabolic health. Dysbiosis accelerates aging.
Intestinal Integrity – A healthy gut lining prevents “leaky gut,” which drives systemic inflammation and immune dysfunction. Maintaining intestinal barrier function is crucial for longevity.
Detoxification – The gut plays a primary role in detoxifying estrogen, bile acids, and other compounds. Poor detoxification drives disease and aging acceleration.
Your Anti-Aging Consultation
During your initial anti-aging consultation, we will:
Assess Your Health History – Understand your family history, current symptoms, lifestyle factors, and health goals.
Measure Biological Age – Order specialized testing to determine your true biological age and identify specific aging accelerants.
Evaluate Digestive Function – Assess your microbiome, nutrient absorption capacity, gut barrier integrity, and digestive efficiency.
Identify Risk Factors – Reveal subclinical pathology and disease risk factors before symptoms develop.
Create Your Anti-Aging Plan – Develop an individualized protocol addressing your specific aging profile, incorporating nutrition, supplementation, procedural diagnostics, and lifestyle optimization.
Monitor Progress – Track your response with periodic testing and follow-up appointments to ensure your protocol is producing meaningful improvements in your biological age markers.

Request an AppointmentFrequently Asked Questions About Anti-Aging Medicine
Is anti-aging medicine different from preventive medicine?
While preventive medicine focuses on preventing disease, anti-aging medicine goes further by actually optimizing biological function and potentially reversing markers of aging. Preventive medicine might aim to prevent heart disease; anti-aging medicine aims to improve cardiovascular fitness and reverse arterial aging. Anti-aging medicine is more comprehensive and proactive than traditional preventive medicine.
Can aging actually be reversed?
Yes, within limits. While we cannot reverse chronologic age, we can improve biological age markers. Research shows that interventions addressing oxidative stress, inflammation, hormone balance, and nutritional status can reverse some aspects of aging at the cellular and systemic level. Some patients see improvements in energy, cognitive function, skin appearance, and disease markers within weeks to months of starting anti-aging protocols.
What is biological age versus chronologic age?
Chronologic age is how many years you’ve lived. Biological age reflects how old your cells and tissues actually are, based on markers like telomere length, cellular damage, inflammation levels, and functional capacity. Two 60-year-old people can have vastly different biological ages. Anti-aging medicine focuses on measuring and improving biological age.
How does the microbiome affect aging?
Your gut bacteria produce critical compounds including short-chain fatty acids (butyrate), vitamins, and anti-inflammatory metabolites. A healthy microbiome supports immune function, digestion, nutrient absorption, and brain health. Dysbiosis (microbial imbalance) drives inflammation and accelerates aging. Optimizing your microbiome through targeted nutrition and supplementation is one of the most powerful anti-aging interventions available.
What role does nutrition play in anti-aging?
Nutrition is foundational to anti-aging. Specific nutrients (antioxidants, anti-inflammatory compounds, amino acids, minerals) support cellular repair, reduce oxidative stress, and maintain mitochondrial function. Additionally, certain foods and eating patterns (Mediterranean diet, intermittent fasting, plant diversity) have been shown to extend lifespan and improve healthspan. Personalized nutrition optimization is central to our anti-aging approach.
How often do I need to see an anti-aging specialist?
Initially, more frequent visits (every 4-6 weeks) help establish your baseline, implement protocols, and monitor response. Once your protocol is optimized and you’re seeing improvements, many patients transition to quarterly visits for ongoing monitoring and adjustment. Some patients in maintenance mode see their anti-aging specialist 1-2 times annually.
Does anti-aging medicine work for everyone?
Anti-aging medicine produces the best results in people who are committed to making lifestyle changes and following recommended protocols. Those with serious underlying diseases may see slower progress but can still benefit. Success depends on adherence, genetic factors, baseline health status, and willingness to make sustained changes.
