Is functional medicine misunderstood—or is it being misrepresented?

In this episode of The Functional Nurse Podcast, Brigitte Sager, FNP makes the case that functional medicine has a branding problem—and explains why nurses are uniquely positioned to help fix it.

She defines what functional medicine is supposed to be: root cause care grounded in biochemistry, lifestyle, environment, and systems thinking—not expensive tests, stacks of supplements, or trendy health claims.

Brigitte breaks down three key factors driving the confusion:

1. Overuse of functional lab testing that doesn’t change the plan of care

2. Profiteering around supplements without clear clinical rationale

3. Unlicensed or undertrained individuals using the term "functional medicine"

You’ll also hear her framework for ethical, clear, and patient-centered practice:

• Focus on low-hanging fruit first (sleep, digestion, stress, diet, exposures)

• Use testing only if it changes the clinical plan

• Be crystal clear about why supplements are used, what they’re for, and how long they’re needed

• Frame care as education, partnership, and physiology-based support within nursing scope

Finally, Brigitte explores how nurses can shift the narrative—by using the language of nursing, role modeling results, sharing evidence-based strategies, and choosing accurate, ethical framing like “holistic nursing” when appropriate.

This is a must-listen for nurses, NPs, and nurse educators working to restore trust in functional care and deliver it with clarity, integrity, and clinical rigor.
