WHO AM I

Hi, I'm Free Dominguez.

CNC, FDNP, a Functional Diagnostic Nutrition Practitioner supporting whole-person health.

I’m a Certified Nutrition Consultant (CNC) and Functional Diagnostic Nutrition Practitioner (FDNP). My work is rooted in curiosity about the body as an interconnected system, and a deep respect for each person’s lived experience, history, and goals.

I focus heavily on gastrointestinal issues, hormone and thyroid health, autoimmunity, metabolic dysfunction, performance and optimization, complex immune cases, and fertility care. Within women’s health, I help navigate the multifactorial landscape of PMOS (formerly “PCOS”) and endometriosis.

I frequently work alongside physicians and specialize in concierge care, supporting chart-topping artists, actors, athletes, and other high-demand professionals.

Through comprehensive lab screenings and detailed lifestyle review, I help clients uncover the hidden stressors driving their symptoms, then partner with them on a clear, evidence-based path forward, always alongside their medical team, never in place of it.

A functional, whole-person approach.

Both conventional medicine and functional nutrition have an important role. Many people, however, get stuck in cycles of symptom management. As a Functional Diagnostic Nutrition Practitioner (FDN), I do not diagnose, treat, or prescribe. My role is to support the whole person and help identify underlying stressors that may be driving symptoms.

The body is an interconnected system made up of several key subsystems: the hormonal system, immune system, detoxification pathways, digestive system (including enzymes and the microbiome), nervous system and stress response, and cellular energy systems. Each person has their own detailed history and lifestyle. While our healthcare system excels at acute care and some preventative measures, it often works in silos, rarely evaluating full thyroid function, estrogen recirculation and hormone metabolism, enzyme function, nutrient absorption, comprehensive gut health, or how the nervous and immune systems may be involved.

Facilitating comprehensive labs (blood, urine, saliva, and stool) alongside detailed medical history and lifestyle review, I look for hidden stressors across multiple systems. This evidence-based, individualized approach helps build something comprehensive for the person to "opt in for self-treatment," as we work together for a period of time. We move beyond quick fixes and trial-and-error, working alongside your medical team, not instead of it.

What is Functional Nutrition?

Functional nutrition connects the dots between food, biochemistry, and symptoms. Lab screenings support how your body actually functions, as opposed to generic guidelines that can leave someone chasing more symptoms with unanswered questions.

True longevity does not come from "chasing longevity" and fads; through actual data, those often put more stress on the body. A guided, systematic, evidence-based approach can deliver real and longstanding results.
