Rancho Santa Fe Complementary Medicine

In today’s complex healthcare landscape, more individuals and families in Rancho Santa Fe are seeking a better way to manage their health — one that moves beyond temporary fixes and gets to the root cause of illness. That’s where complementary medicine comes in: a modern, holistic approach that blends the best of conventional care with evidence-based natural therapies to restore balance, enhance vitality, and promote long-term wellness.

Known for its wellness-conscious and high-performing residents, Rancho Santa Fe is a community that values quality, proactive health solutions. Whether it’s hormonal imbalance, chronic fatigue, digestive dysfunction, or simply the desire to age well and stay sharp, locals are turning to providers who offer personalized, preventive, and natural care — not just prescriptions and procedures.

At the Stengler Center for Integrative Medicine, Dr. Mark Stengler, NMD, delivers a care model that’s as unique as it is effective. As a nationally recognized integrative physician, Dr. Stengler combines advanced diagnostics and scientific precision with Christian compassion and individualized attention. Each patient receives a tailored plan designed to support their body’s God-given ability to heal — physically, emotionally, and spiritually.

From busy executives to health-minded families, Rancho Santa Fe patients appreciate Dr. Stengler and his team's ability to deliver targeted, whole-person treatments that respect both modern medicine and natural healing wisdom. If you're seeking more than a quick fix — if you're looking for clarity, balance, and long-term health — the Stengler Center is here to guide your journey.

What Is Complementary Medicine?

Complementary medicine refers to the use of natural, evidence-based therapies alongside conventional medical treatments to support the body’s healing process and improve health outcomes. Rather than replacing traditional medicine, complementary care enhances it — offering a more holistic, personalized approach to wellness.

Clarifying the Terminology

It's common for terms like “complementary,” “alternative,” and “integrative” medicine to be used interchangeably, but there are important differences:

  • Complementary Medicine is used with conventional care. For example, a patient being treated for hypothyroidism might also receive nutrition counseling and herbal support to improve energy and balance.
  • Alternative Medicine is used instead of standard medical care. This approach may exclude modern diagnostics or treatments — which we do not recommend or practice at our clinic.
  • Integrative Medicine combines the best of both worlds — merging modern diagnostic tools and conventional treatment with proven natural therapies, all tailored to the patient’s unique needs. This is the foundation of Dr. Stengler’s approach.

Benefits of Complementary Medicine at the Stengler Center

  • Whole-person care that addresses the physical, emotional, and spiritual aspects of health
  • Focus on prevention, not just symptom management
  • Reduced reliance on medications by supporting the body’s natural healing mechanisms
  • Enhanced quality of life, even in chronic or complex conditions

For those in Rancho Santa Fe who prioritize wellness, longevity, and proactive healthcare, complementary medicine offers a powerful, personalized path to lasting vitality — all delivered with integrity and compassion.

Core Services at the Stengler Center for Rancho Santa Fe Patients

Bioidentical Hormone Replacement Therapy (BHRT)

Hormonal changes are a natural part of aging — but that doesn’t mean you have to live with fatigue, weight gain, irritability, or low libido. At our clinic, we offer Bioidentical Hormone Replacement Therapy (BHRT) as a safe, effective way to restore balance and vitality for both men and women.

For Women:

  • Menopause: hot flashes, night sweats, mood changes
  • Adrenal burnout: fatigue, anxiety, poor stress resilience
  • Emotional and mental imbalance during hormonal shifts

For Men:

  • Low testosterone (Andropause): decreased strength, energy, and drive
  • Mental fog and low motivation
  • Mood swings, poor sleep, and midlife weight gain

Why Choose BHRT at the Stengler Center?

  • Customized dosing based on comprehensive hormone testing
  • Bioidentical compounds that are molecularly identical to your body’s own hormones
  • Ongoing monitoring and support to ensure optimal, safe results

BHRT is one of our most in-demand services for Rancho Santa Fe patients who want to age with clarity, confidence, and energy — without relying on synthetic hormone drugs.

Clinical Nutrition & Targeted Supplementation

Even the most health-conscious individuals can suffer from hidden nutrient deficiencies or suboptimal metabolism. At the Stengler Center, we use functional lab testing to identify nutritional gaps and create personalized nutrition plans that support energy, immunity, and hormone balance.

Foundational Nutrients We Prioritize:

  • Vitamin D: critical for immune and hormonal health
  • Probiotics: essential for gut balance, digestion, and inflammation control
  • Omega-3 fatty acids: vital for heart, brain, and mood regulation

Conditions Supported by Nutritional Protocols:

Every supplement recommendation is backed by clinical evidence and tailored to your lab results — using only medical-grade products with verified purity and potency. This approach allows our Rancho Santa Fe patients to experience real, lasting improvements without the guesswork of over-the-counter supplementation.

IV Nutrient Therapy

For those looking to boost immunity, restore energy, or recover more quickly from illness, IV nutrient therapy offers fast, targeted results. Unlike oral supplements, intravenous delivery ensures that vitamins and minerals go directly into the bloodstream, bypassing the digestive system for maximum absorption and efficiency.

Ideal For:

  • Immune support during cold, flu, or viral seasons
  • Chronic fatigue and burnout, often from high stress or overwork
  • Post-viral recovery, including lingering symptoms after COVID or other infections
  • Athletic performance and recovery

Our Most Popular IV Infusions:

  • High-Dose Vitamin C: An antioxidant powerhouse that supports immunity, collagen formation, and detoxification
  • Myers’ Cocktail: A blend of B vitamins, magnesium, calcium, and Vitamin C — excellent for stress recovery, energy, and mood support

Each IV protocol is administered safely under clinical supervision, based on your personal needs and lab results. For many of our Rancho Santa Fe patients, IV therapy becomes a regular part of their wellness routine.

Digestive Health Optimization

Digestive issues are often the root of broader health problems — from inflammation and fatigue to autoimmune dysfunction and nutrient deficiencies. At the Stengler Center, we offer a thorough, functional approach to digestive health that gets to the source of your symptoms and supports long-term gut healing.

Conditions We Commonly Address:

  • IBS (Irritable Bowel Syndrome)
  • SIBO (Small Intestinal Bacterial Overgrowth)
  • Leaky Gut Syndrome
  • Acid reflux, bloating, and food intolerance

Our Diagnostic Process:

We use advanced testing to assess your gut health in detail:

  • Stool analysis to evaluate digestion, inflammation, infections, and microbiome status
  • SIBO breath testing to identify bacterial imbalances
  • Food sensitivity screening to detect delayed immune reactions that contribute to inflammation

Natural Tools for Gut Healing:

  • Customized healing diets, such as low-FODMAP, gluten-free, or anti-inflammatory protocols
  • High-quality probiotics and digestive enzymes
  • Herbal antimicrobials to gently rebalance the gut microbiome

Our integrative model ensures that every digestive treatment plan is tailored to your body and lifestyle, empowering Rancho Santa Fe patients to reclaim digestive health and overall wellness — naturally.

Adrenal & Thyroid Support

When energy crashes, sleep becomes restless, and motivation fades, the adrenal and thyroid glands are often at the center of the imbalance. Unfortunately, conventional medicine may overlook the early signs of adrenal fatigue or subclinical hypothyroidism — leaving patients frustrated and untreated. At the Stengler Center, we take a comprehensive, functional approach to restoring hormone balance and vitality.

Common Symptoms We Address:

  • Stress-related fatigue and difficulty waking in the morning
  • Brain fog, anxiety, and low mood
  • Unexplained weight gain or cold intolerance
  • Sleep disturbances and hormonal fluctuations
  • Hashimoto’s thyroiditis and other autoimmune thyroid conditions

Our Integrative Approach Includes:

  • Advanced functional labs to evaluate cortisol rhythms, thyroid hormones (TSH, Free T3, Free T4), and thyroid antibodies
  • Personalized nutrient therapy with key cofactors like selenium, iodine (when appropriate), B vitamins, and adaptogenic herbs
  • Lifestyle and spiritual coaching for stress resilience, restful sleep, and emotional support

Rather than relying solely on prescriptions, we use a whole-person strategy to balance these essential systems — supporting thyroid function, adrenal resilience, metabolism, and mental clarity.
