The Unspoken Grief Nurses Carry (And How We Begin to Heal)
A Conversation That Hit Deeper Than Expected Last month, during one of our Functional Nursing Membership MeetUps, I sat down with the intention of leading a discussion on how stress and trauma impact our patients. But as I mentally prepared for leading the discussion, something shifted. Instead of staying purely clinical, the topic and conversation became deeply personal. We found ourselves opening up about what it really means to practice as a nurse—the unseen burdens we car

Is Functional Medicine Evidence-Based? What Nurses Should Know
Let’s Clear the Air If you’re a nurse who has ever asked, “Is functional medicine even evidence-based?” you’re not alone—and you’re not wrong to ask. Nurses are trained to think critically, assess data, and practice based on proven interventions. So when we hear terms like "root cause" or "functional approach," it’s completely fair to wonder: Is this grounded in real science or just another wellness trend? Here’s the short answer: Yes, functional medicine is absolutely eviden

Are Food Dyes Harmful? A Functional Nursing Perspective
Food dyes have been making headlines lately, and for good reason. In a move that has been long overdue, Red Dye No. 3 was recently banned from food in the U.S. —yet it had already been prohibited in cosmetics for over 30 years. Let that sink in. The same dye deemed unsafe for lipstick and skincare was still being used in children’s snacks and drinks until now. This raises an important question: If a chemical isn’t safe for our skin, why has it been allowed in our food? As fu

Environmental Biohacking for Nurses: How to Reduce Toxins and Optimize Health
As nurses, we dedicate much of our lives to healing others, but how often do we think about the environment we’re working and living in? Our surroundings—at home, at work, and even in the air we breathe—directly impact our health. We’re exposed to toxins daily, from the disinfectants used in healthcare settings to the air pollution in our neighborhoods. If we want to show up as the healthiest versions of ourselves for our patients and our families, environmental biohacking is

Empowering Holistic Nurses to Approach Vitamin D Deficiency Beyond Outdated Guidelines
Winter in the Pacific Northwest is a time for grey cloud cover and drizzle. A fairly well-known side effect of the season is a common health challenge: vitamin D deficiency. Here in the PNW, the lack of sunlight during the colder months leaves many of us vulnerable to low levels of this essential nutrient. While a sunny winter getaway might feel like a temporary fix (and one of my favorite interventions), it’s not enough to sustain your body’s needs. And it’s not just PNW res

The Real Reason Nurses Feel Burned Out (And How Functional Medicine Can Help)
Why So Many Nurses Feel Stuck in Traditional Healthcare Nursing is often described as a calling—a deep-rooted desire to help, heal, and care for others. But for many nurses, the reality of working in hospitals and clinics doesn’t always align with the vision that first led us into the profession. I remember the weight of long, dizzying overnight shifts, the constant charting, and the endless patient load. Despite pouring everything I had into patient care, I would leave work
