About Christina
25 years of nursing. A different kind of approach.
Christina Vandersluis · Functional Nutrition Practitioner
Her story
From nursing to functional nutrition
Christina spent 25 years as a Registered Nurse — much of it in emergency and trauma care — where she learned to think quickly, look at the whole picture, and ask better questions.
Over time, she noticed a pattern: women with real, persistent symptoms — fatigue, brain fog, weight changes — repeatedly told their results were normal. The standard system wasn't built to look deeper. Christina was.
That curiosity led her to functional nutrition — a discipline that treats the body as an interconnected system, not a set of isolated lab values. She now brings that clinical and nutritional lens to women navigating thyroid concerns, perimenopause, and the gap between 'normal' results and how they actually feel.
Her approach
Collaborative. Educational. Grounded in clinical experience.
She works with your care team — not instead of them
Christina's role is to help you understand your health picture more fully and to support better conversations with your existing physicians and specialists. She ensures your care team in involved by providing collaboration letters.
She asks the questions that often go unasked
After 25 years in clinical nursing, Christina knows how to read between the lines of a lab report. She looks at functional ranges, patterns across systems, and the relationship between thyroid, gut, hormones, and metabolism — not just individual values in isolation.
She meets you where you are
Whether you're newly diagnosed, years into managing a thyroid condition, or simply exhausted and looking for answers — Christina's approach is practical, realistic, and designed to fit your actual life. No overwhelm. No rigid protocols. A starting point that makes sense for you.
She believes you deserve more than 'normal'
Standard reference ranges were designed to identify disease — not to define optimal health. Christina uses functional ranges to identify patterns that standard screening often misses, and to help you understand what your body may actually be communicating.
