Dr. Rachel Erickson, Naturopath, L.Ac.

Confused about the difference between a naturopath and a functional medicine doctor? You’re not alone. Learn how these two holistic health approaches compare—and how to choose the right one for you.

If you’re exploring holistic or integrative approaches to healthcare, you’ve likely come across the terms naturopathic medicine and functional medicine. While they share some core values—like treating the root cause, supporting the body’s natural healing abilities, and using natural therapies—they are not the same.

Let’s break down the key differences so you can make an informed choice about which approach may be best for your health journey.

What Is Naturopathic Medicine?

Naturopathic medicine is a distinct, licensed healthcare profession that blends traditional healing wisdom with modern science. Naturopathic doctors (NDs) are trained in both conventional diagnostics and natural therapies like nutrition, herbal medicine, lifestyle counseling, homeopathy, and physical medicine.

Key Principles of Naturopathic Medicine:

Treat the root cause, not just symptoms
Use the least invasive methods first
Support the body’s innate ability to heal
Treat the whole person—body, mind, and spirit
Focus on prevention and patient education

Naturopathic doctors typically attend a 4-year accredited naturopathic medical school and are licensed in many U.S. states and Canadian provinces.

What Is Functional Medicine?

Functional medicine is a method or framework of practicing medicine that focuses on personalized, systems-based care. Rather than being a distinct medical license, it is an advanced clinical approach used by a variety of providers—often MDs, DOs, NDs, or nurse practitioners—who undergo additional training in functional medicine.

Functional medicine practitioners use a detailed analysis of genetics, environment, lifestyle, and lab work to find the underlying causes of disease. They often use advanced testing and targeted interventions such as nutrition, supplements, and hormone balancing.

Core Concepts in Functional Medicine:

Systems biology: viewing the body as interconnected systems
Personalized care: tailored to the individual’s biochemistry
In-depth lab testing and data-driven analysis
Strong emphasis on lifestyle medicine

Similarities Between Naturopathic and Functional Medicine

Root-cause approach: Both aim to uncover why you're experiencing symptoms, not just suppress them.
Whole-person care: Each takes into account diet, lifestyle, environment, and emotional health.
Use of natural therapies: Both use non-pharmaceutical methods when appropriate, though may include medications if needed.
Patient-centered: Time is spent understanding your full history and building a collaborative relationship.

Which One Should You Choose?

The best approach depends on your needs:

If you're looking for a licensed provider focused on natural therapies, prevention, and lifestyle change, a naturopathic doctor may be a great fit.
If you're seeking a deep dive into lab work, hormones, and personalized protocols—especially for complex, chronic conditions—a functional medicine practitioner could offer what you need.

In many cases, these approaches work beautifully together, and some providers are trained in both!

Final Thoughts

Both naturopathic and functional medicine aim to put the patient at the center and prioritize long-term healing over quick fixes. Understanding their unique backgrounds and strengths can help you feel more confident about choosing a provider who aligns with your health goals.
