What Is Naturopathic Medicine?

Naturopathic medicine is a distinct holistic primary care profession that blends modern medical science with evidence-informed natural therapies. Licensed naturopathic doctors complete doctoral-level training in biomedical sciences, diagnostics, and clinical medicine, along with advanced education in nutrition, botanical medicine, supplements, lifestyle medicine, and physical medicine.

The goal is to move away from medical management of disease and toward restoring balance across interconnected systems, including the immune, endocrine, and nervous systems.

What Is Functional Medicine?

Functional medicine is a systems-based approach that focuses on understanding how physiological networks interact throughout the body. Rather than waiting for structural disease changes to appear on standard laboratory testing, functional medicine often evaluates earlier shifts in physiology that may contribute to symptoms.

It frequently utilizes specialized laboratory testing to assess biochemical patterns and functional imbalances before more advanced tissue changes occur.

This may include evaluating:

• Hormone signaling through DUTCH testing or other functional hormone panels
• Gut integrity and microbiome balance through comprehensive stool analysis or GI-MAP
• Detoxification pathways and liver metabolism
• Immune activation patterns
• Blood sugar regulation
• Nutrient status through cellular micronutrient testing such as SpectraCell
• Chronic inflammation markers

Functional medicine serves as an effective bridge between conventional care and integrative medicine because it uses laboratory data and physiologic assessment to better understand how the physical body is functioning.

At the same time, functional medicine primarily focuses on the biochemical and physiological aspects of health. It does not, by itself, address the mental, emotional, relational, or energetic dimensions of healing.

For this reason, at Whole Systems Healthcare Boulder, functional medicine is practiced within a broader holistic medical framework. When combined with naturopathic and East Asian medicine, functional findings are interpreted within a broader and more integrated framework of health and disease.

This integrative model allows laboratory insight to inform care while ensuring treatment remains personalized, relational, and centered on the whole person.

How I Use Holistic Medicine in My Practice

By Donald Spears, ND, MSOM, LAc

Practicing holistic medicine in Boulder, Colorado is unique.

Many of the patients who walk into my office are already proactive about their health. They eat well. They exercise regularly. They spend time outdoors. They may already have a supplement routine. Some have worked with alternative practitioners. Others have completed extensive conventional or functional lab testing.

They are not uninformed.

And yet, many still feel like something is missing.

They may have lab results. They may have a diagnosis. They may understand pieces of their physiology. But they often lack a cohesive framework that weaves those pieces together into a meaningful and actionable path forward.

This is where naturopathic and functional medicine serve a larger role within holistic medicine.

Functional medicine gives us powerful tools to understand physiology. Advanced laboratory testing can help illuminate hormone signaling, inflammation patterns, metabolic shifts, immune activation, and nutrient status. These insights are valuable.

Naturopathic medicine offers a systems-based foundation guided by an organizing philosophy and therapeutic order. Instead of chasing isolated lab markers, it evaluates how digestion, stress, sleep, and lifestyle interact to shape the whole system. Treatment is layered strategically, supporting foundational physiology before adding complexity.

And holistic medicine goes even further.

Holistic medicine begins with the whole person.

In my practice, I use multiple holistic lenses to understand the patient in front of me. I consider laboratory data, clinical presentation, constitutional tendencies, stress load, emotional patterns, life stage, and environmental exposures. I look for the organizing pattern rather than chasing isolated symptoms.

In Boulder, it is common for patients to have already gathered information. What they often need is integration.

Rather than adding more supplements or more data, my work is often about clarifying direction. It is about identifying what matters most, what is driving the pattern, and how to support the body in a way that creates coherence rather than complexity.

Because true health is not achieved by stacking protocols.

It emerges when the systems of the body are working in relationship.

By grounding functional insights within holistic philosophy, we create treatment plans that are personalized, strategic, and sustainable. The result is not just symptom improvement, but a deeper level of integration that many patients have not experienced before.

Every patient presents with a unique pattern. My role is to understand that pattern clearly and guide the body toward balance using the appropriate combination of naturopathic medicine, functional medicine, and holistic clinical insight.

What to Expect at Your First Visit

• Detailed review of symptoms and health history
• Discussion of previous labs and testing
• Identification of key drivers

Care plans are dynamic and adjusted as your physiology responds.

Frequently Asked Questions

Naturopathic doctors are medically trained primary care providers in select states. In Colorado, naturopathic doctors provide comprehensive integrative care but are not recognized as conventional primary care providers by the state.

Colorado does not grant prescriptive rights to naturopathic doctors. We collaborate with conventional providers when prescription medications are part of your care plan.

Yes. We frequently collaborate with primary care providers, specialists, therapists, and other clinicians.

This depends on the complexity and duration of symptoms. Some patients notice early shifts within weeks, while chronic patterns may require several months of consistent care.
