San Marcos Complementary Medicine

In today’s fast-paced world, more individuals and families are seeking healthcare that goes beyond managing symptoms — they want lasting, whole-body healing. That’s where complementary medicine comes in.

Complementary medicine refers to evidence-based natural therapies used alongside conventional medical care to support the body’s natural ability to heal. It’s not about choosing one system over another — it’s about combining the best of both. This approach is ideal for those who want to reduce their reliance on medications, address the root cause of their symptoms, and pursue true wellness.

In the heart of North County, the San Marcos community is becoming a vibrant hub for holistic living and preventive health. From young professionals to growing families and active seniors, many are seeking care that aligns with their lifestyle and values. Whether you're navigating fatigue, digestive issues, hormonal changes, or simply want to stay ahead of chronic illness, personalized, natural care is in high demand.

At the Stengler Center for Integrative Medicine, Dr. Mark Stengler offers San Marcos patients a unique model of care that blends:

  • Advanced functional diagnostics
  • Research-based natural treatments
  • And faith-rooted compassion that honors your beliefs and values

Our clinic, conveniently located just a short drive from San Marcos, serves as a trusted resource for individualized health plans tailored to your body, lifestyle, and wellness goals. We offer a peaceful, respectful environment where patients of all ages can find answers, hope, and long-term healing.

If you're in the San Marcos area and ready to move beyond band-aid solutions, discover what true integrative medicine can do for your life.

What Is Complementary Medicine?

Complementary medicine refers to therapies that are used alongside standard medical treatments to enhance healing, support the body’s natural functions, and promote long-term wellness. It bridges the gap between conventional and natural care — allowing patients to benefit from both worlds.

As more people in San Marcos seek personalized, whole-person healthcare, complementary medicine offers a practical, evidence-based approach that fits seamlessly into their existing care plans.

Understanding the Differences:

  • Complementary Medicine = used with conventional care (e.g., clinical nutrition to support a patient with diabetes)
  • Alternative Medicine = used instead of conventional care (not recommended at the Stengler Center)
  • Integrative Medicine = a thoughtful, customized blend of both — the model used by Dr. Mark Stengler

This distinction matters because integrative and complementary care works in partnership with your existing doctors, prescriptions, and diagnoses — offering a safe and supportive path to better health.

Why San Marcos Patients Choose Complementary Medicine:

  • Root-Cause Focus: Rather than masking symptoms, we dig deep to uncover what’s causing your fatigue, hormonal imbalance, digestive trouble, or immune weakness.
  • Less Reliance on Medications: Many patients are able to reduce or avoid medications by supporting the body through nutrition, hormone balance, and lifestyle change.
  • Prevention-Oriented: By identifying risk factors early, we help prevent disease before it starts.
  • Vitality and Longevity: The goal isn’t just avoiding illness — it’s living with strength, clarity, and joy.

Whether you’re managing chronic issues or simply seeking optimal wellness, complementary medicine offers San Marcos residents a smarter, more personalized path to healing.

Bioidentical Hormone Replacement Therapy (BHRT)

Hormonal imbalances can impact every aspect of your life — from mood and energy to sleep, metabolism, and even spiritual well-being. Bioidentical Hormone Replacement Therapy (BHRT) offers a safe, natural way to restore balance without the risks associated with synthetic hormones.

For Women:

  • Perimenopause and Menopause: mood swings, hot flashes, low libido, sleep disruptions
  • Adrenal Fatigue: stress-related burnout, irritability, and energy crashes

For Men:

  • Testosterone Decline: fatigue, brain fog, reduced muscle mass, and loss of motivation
  • Andropause: the male version of menopause, often overlooked but deeply impactful

Why BHRT Works:

  • Uses plant-derived hormones that are biologically identical to those your body produces
  • Personalized dosing based on lab testing and symptom tracking
  • Helps improve energy, mood, mental clarity, libido, and quality of life

BHRT is ideal for San Marcos residents who want to feel like themselves again — with a safe, customized plan grounded in both science and natural medicine.

Clinical Nutrition & Personalized Supplementation

What you feed your body directly affects your energy, hormones, brain function, and immune system. But even a clean diet isn’t always enough in today’s world of stress and nutrient-depleted soil. That’s why we offer functional nutrition plans paired with lab-guided supplementation.

Core Nutrients We Prioritize:

  • Vitamin D – essential for immunity, hormones, and bone health
  • Magnesium – supports sleep, mood, and blood sugar regulation
  • Omega-3s – reduce inflammation and support brain and cardiovascular health
  • Probiotics – strengthen digestion and immunity

Targeted Nutrition Protocols for:

  • Fatigue and burnout
  • Leaky gut and digestive distress
  • Thyroid imbalance and sluggish metabolism
  • Blood sugar swings and early-stage insulin resistance

Using comprehensive lab testing, we identify nutrient deficiencies and build a supplement plan tailored to your body’s needs — not just trends. San Marcos patients appreciate our commitment to high-quality, evidence-based supplements that are safe, effective, and compatible with their values.

IV Nutrient Therapy

When your body is run down — whether from chronic stress, illness, or poor nutrient absorption — oral supplements may not be enough. That’s why many San Marcos patients turn to IV Nutrient Therapy for fast, powerful replenishment.

Unlike pills or powders, IV therapy delivers vitamins and minerals directly into the bloodstream, bypassing digestion for immediate absorption and optimal effectiveness.

Ideal For:

  • Immune system recovery
  • Chronic fatigue and burnout
  • Post-viral recovery, including long COVID or frequent infections

Popular IV Infusions at the Stengler Center:

  • Myers’ Cocktail – A time-tested blend of B vitamins, magnesium, calcium, and Vitamin C for energy, mood, and immune support
  • High-Dose Vitamin C – A potent antioxidant infusion used for immunity, inflammation, and chronic stress recovery

Whether you’re preparing for travel, recovering from illness, or need an energy reboot, IV therapy offers a safe, efficient, and restorative solution — with the oversight of our experienced integrative team.

Digestive Health & Gut Repair

The digestive system plays a central role in nearly every aspect of wellness — from nutrient absorption and hormone regulation to immune strength and brain clarity. At the Stengler Center, we help San Marcos patients uncover and heal the root causes of digestive discomfort through advanced testing and natural therapies.

Conditions We Commonly Address:

Diagnostic Testing Includes:

  • Comprehensive stool analysis to assess gut flora, inflammation, and digestion
  • SIBO breath tests to identify bacterial overgrowth
  • Food sensitivity screening to uncover hidden immune triggers

Our Holistic Gut-Healing Approach:

  • Personalized healing diets to reduce inflammation and restore gut lining integrity
  • Herbal antimicrobials to safely rebalance bacteria and reduce overgrowths
  • High-potency probiotics and enzymes to optimize digestion and nutrient uptake

We don’t just manage symptoms — we guide your body back to digestive harmony with natural, non-invasive care rooted in research and respect for the body’s God-given design.

Adrenal & Thyroid Recovery

In today’s high-stress world, adrenal fatigue and thyroid dysfunction are increasingly common — especially among women and professionals juggling work, family, and life demands. If you’re in the San Marcos area and experiencing persistent fatigue, poor sleep, or mood swings, this may be the missing piece.

At the Stengler Center, we specialize in natural, science-based support for the adrenal-thyroid connection, using advanced testing and gentle, whole-body healing protocols.

Signs You May Benefit:

  • Ongoing fatigue, even after a full night’s sleep
  • Brain fog, irritability, or anxiety
  • Weight gain, dry skin, or hair thinning
  • Diagnosed hypothyroidism or Hashimoto’s thyroiditis

Lab Testing Includes:

  • Cortisol rhythm panels to assess adrenal stress response
  • Thyroid labs: TSH, Free T3, Free T4, reverse T3, and thyroid antibodies
  • Nutrient levels for key cofactors like selenium, iodine, zinc, and vitamin D

Natural Recovery Tools:

  • Adaptogenic herbs (like ashwagandha or rhodiola) to build stress resilience
  • Targeted nutritional support to correct deficiencies and fuel thyroid function
  • Faith-friendly lifestyle strategies that promote rest, prayer, and renewal

Instead of masking symptoms, we help patients rebalance their energy and metabolism naturally — so they can feel restored, motivated, and in control again.
