Hormone Testing & Optimization

Hormone testing and balancing is a core clinical specialty at JYZEN, led by Dr. Beth McDougall, M.D., whose integrative practice has centered on hormonal optimization for over two decades. The clinic's hormone panel menu covers male and female sex steroids, adrenal hormones, hormone metabolites, and four-panel comprehensive male and female assessments. Test results inform personalized balancing protocols that may address fatigue, metabolic sluggishness, mood, sleep quality, and body composition concerns associated with suboptimal hormonal function. Hormone evaluation is a foundational component of both the 90-Day Metabolic Reset and the Longevity Program tracks, and is available as a standalone consultation for new clients seeking an initial diagnostic assessment.

Hormone testing and optimization represents one of the clinical pillars at JYZEN's Mill Valley integrative medicine clinic, reflecting the expertise of Chief Medical Officer Dr. Beth McDougall, M.D., who built her 25-year integrative practice substantially around hormonal health as a cornerstone of overall wellbeing and healthy aging. Dr. McDougall's background spans neurodegenerative disease, autoimmune conditions, Lyme disease, and complex chronic illness — contexts in which hormonal dysregulation frequently plays a contributing role that conventional standard-of-care testing misses. JYZEN's hormone panel menu addresses the major axes of the endocrine system that decline, dysregulate, or lose resilience with age and chronic stress. Male sex steroid panels assess total and free testosterone, DHEA-S, estradiol, LH, and FSH — the full picture of androgenic status and gonadotropin feedback, which together reveal whether low androgen levels reflect primary testicular insufficiency, secondary hypothalamic-pituitary signaling, or conversion imbalance. Female sex steroid panels include estradiol, progesterone (timed to cycle phase where applicable), DHEA-S, testosterone (total and free), LH, FSH, and SHBG, enabling characterization of the hormonal environment across perimenopause and post-menopause as well as in younger women with cycle irregularities, mood symptoms, or unexplained fatigue. Adrenal hormone assessment at JYZEN goes beyond a standard cortisol check to evaluate the full diurnal cortisol rhythm — capturing morning peak, afternoon, and evening values — along with DHEA and adrenaline metabolites, providing insight into HPA axis function and resilience that single-point serum cortisol cannot offer. Hormone metabolite panels, typically performed via urine, map the downstream pathways through which estrogens and androgens are broken down, identifying whether metabolism favors protective or less favorable metabolite ratios — a level of nuance that informs intervention strategy and risk assessment beyond standard blood hormone levels. The comprehensive male or female four-panel assessment integrates the above into a complete endocrine picture. Findings are interpreted by Dr. McDougall and the JYZEN clinical team, and translated into a personalized optimization protocol that may include targeted nutraceutical support, lifestyle interventions, or physician-supervised hormone balancing. Hormone testing is a foundational component of the 90-Day Metabolic Reset program and both tracks of the Longevity Program, and is also available to new clients through an initial consultation without requiring program enrollment.
