Athletic Performance Optimization in Los Angeles

Physician-Led Precision Medicine for Peak Performance, Recovery, and Longevity

Athletic performance is not determined by training alone. Instead, it reflects how efficiently your body produces energy, regulates hormones, recovers from stress, and adapts at a cellular level.

At Advance Health Integrative And Functional Medicine, Dr. Rashel Tahzib provides a physician-led, highly personalized approach to athletic performance optimization. By combining functional, integrative, anti-aging, and regenerative medicine, care is designed to enhance performance while supporting long-term health.

Whether your goal is to improve strength, endurance, recovery, or cognitive performance, this model focuses on identifying and correcting the underlying factors that may be limiting your full potential.

A Comprehensive, Systems-Based Approach to Performance

Optimizing the Body as an Interconnected System

Performance is influenced by multiple systems working together. Therefore, isolated interventions often fail to produce lasting results.

For this reason, care is structured to evaluate and optimize:

  • Hormonal balance and endocrine function
  • Metabolic and mitochondrial efficiency
  • Gut health and nutrient absorption
  • Immune function and inflammation
  • Neurologic and cognitive performance
  • Genetic predispositions and biochemical individuality

As a result, this integrated approach allows for a more precise and effective performance strategy.

Advanced Testing to Identify Limiting Factors

Data-Driven Precision Medicine

In many cases, performance plateaus occur because underlying imbalances have not been identified. Standard testing often overlooks these factors.

Therefore, advanced diagnostics are used to uncover what may be impacting performance, recovery, and resilience.

Genetic and SNP Testing

Genetic and SNP analysis provides insight into how your body functions at a foundational level. Specifically, this testing helps evaluate:

  • Methylation and detoxification pathways
  • Inflammatory and oxidative stress responses
  • Energy production and mitochondrial function
  • Muscle recovery and adaptation patterns
  • Nutrient metabolism and utilization

Consequently, interventions can be tailored to align with your unique biology.

Nutrigenomics and Personalized Nutrition

Nutrition is one of the most powerful tools in performance optimization. However, generalized plans often fall short.

Through nutrigenomic analysis, your nutrition strategy can be aligned with your physiology. This includes:

  • Individual macronutrient needs
  • Micronutrient optimization
  • Identification of inflammatory triggers
  • Improved metabolic flexibility

As a result, nutrition becomes a targeted tool rather than a trial-and-error process.

Hormone Balance And Optimization

Hormones play a central role in performance, recovery, and body composition. When imbalances are present, performance can be significantly affected.

Evaluation may include:

  • Testosterone, estrogen, and progesterone
  • Thyroid function
  • Cortisol and adrenal balance
  • Growth hormone pathways

When appropriate, targeted interventions are implemented to restore balance and support optimal function.

Gut Health and Microbiome Function

Take your health to the next level by optimizing gut health. Your gut is directly linked to nutrient absorption, immune function, and inflammation. Therefore, optimizing gut health is essential for performance.

Assessment may include:

  • Microbiome balance
  • Digestive efficiency
  • Intestinal permeability
  • Inflammatory markers

By addressing these factors, the body is better able to absorb and utilize nutrients effectively.

Immune Optimization and Inflammation Control

Chronic inflammation can impair recovery, reduce endurance, and increase injury risk. In many cases, this is an overlooked contributor to performance limitations.

Accordingly, care focuses on identifying and modulating immune pathways to improve resilience and recovery capacity.

Targeted Therapies for Performance Enhancement

Personalized, Physician-Guided Interventions

Once key drivers are identified, a personalized plan is developed. This ensures that interventions are both strategic and effective.

Targeted Nutrient Optimization

Nutrient therapy is used to support cellular function and energy production. In particular, this may enhance:

  • Mitochondrial performance
  • Muscle recovery and repair
  • Reduction of oxidative stress
  • Metabolic efficiency

Peptide Therapy for Performance and Recovery

When clinically appropriate, peptide therapy may be incorporated as part of a comprehensive plan.

These therapies may support:

  • Muscle recovery and tissue repair
  • Endurance and performance capacity
  • Fat metabolism and body composition

All treatments are carefully selected and supervised within a physician-led model.

Integrating Performance with Longevity

Sustainable, Long-Term Optimization

While short-term gains are important, long-term health must also be considered. Therefore, performance strategies are designed to support longevity as well.

This includes:

  • Cardiometabolic health optimization
  • Hormonal longevity
  • Reduction of chronic disease risk
  • Cognitive performance preservation

Performance Without Compromise

Importantly, this approach prioritizes strategies that enhance performance without negatively impacting long-term health.
