A deeper, root-cause approach to healing
I’m Nikki Santangelo, FDNP, and I’m passionate about helping women get real answers. Through functional lab testing and a deeper root-cause approach to healing, I work with clients to uncover hidden imbalances and build a plan that finally makes them feel heard, supported, and understood – guiding you toward clarity, balance, and true healing.

Conventional lab work often comes back “normal,” even when you don’t feel normal. This is because standard reference ranges are based on the average population – including people who are already unwell. In functional health, we assess labs using optimal ranges, giving us a clearer picture of your body’s early imbalances long before they become symptoms or diagnosed conditions.
As a Functional Diagnostic Nutrition Practitioner (FDNP), I specialize in interpreting labs through this functional lens. My goal is to help you identify hidden stressors, uncover the “why” behind your symptoms, and build a personalized plan that supports true healing – not just symptom management.
What Functional Labs Can Reveal
Functional testing provides deeper insights than conventional labs alone. These tests help uncover imbalances in:
- Digestion and absorption
- Gut pathogens, bacterial overgrowths, and microbiome diversity
- Hormone production, metabolism, and circadian patterns
- Nutrient and mineral status
- Detoxification capacity
- Blood sugar and metabolic markers
- Inflammation and immune function
- Food reactions and hidden sensitivities
This data allows us to create a targeted, root-cause strategy rather than guessing.
