Why HormoneSynergy® Has Trusted Metagenics® for 25 Years
Founded in 1983, Metagenics® has helped set the standard for functional medicine and integrative nutrition, with a focus on research-driven formulations and practitioner guidance. At HormoneSynergy® Clinic, our approach to Longevity Medicine & Healthspan requires supplements that meet a high bar for quality, consistency, and clinical relevance. Metagenics® has consistently delivered.
Over the decades, our clinical team has relied on Metagenics® to support a wide range of health goals—especially when paired with personalized care and advanced testing strategies. We recommend supplements not because they’re popular, but because they’re chosen to support your physiology, goals, and long-term outcomes.
A Shared Commitment to Practitioner-Guided Care
Metagenics® products are designed to be used with professional support—an approach aligned with Dr. Kathryn Retzler’s 25+ years in integrative and functional medicine. This practitioner-guided philosophy supports smarter personalization for individuals seeking optimized wellness, healthy aging, and metabolic resilience.
At HormoneSynergy® and RetzlerRx®, we offer both trusted Metagenics® formulations and physician-formulated support through our own line: RetzlerRx® physician-formulated supplements. Many people use these together as part of a comprehensive plan.
