Functional Nutrition

Your Symptoms Aren't a Mystery.
They're a Message.

You've been told your labs are normal. You've tried the diets. You've seen the specialists. But you still don't feel right — and you know something is being missed.

Hackett Health runs the tests conventional medicine skips, finds the patterns, and builds a protocol around your actual biology — not a generic plan.

The Problem

Your Symptoms Have Been Building for Years

Most women who come to us have spent years cycling through the same conversation: "Your labs look fine." "Try eating less." "It's probably stress." Meanwhile, the bloating, fatigue, brain fog, and hormonal chaos keep getting worse.

Standard medicine is designed to diagnose disease — not to find dysfunction before it becomes disease. That's the gap we fill.

Standard Medicine

  • TSH only for thyroid
  • No gut microbiome testing
  • Symptom management
  • "Normal" ranges too broad
  • No root-cause protocol

What We Do

  • Full thyroid panel + antibodies
  • Comprehensive gut testing
  • Root-cause investigation
  • Functional reference ranges
  • Personalized protocol

Our Approach

This Is Not Another Diet

We are not here to hand you a meal plan and send you on your way. Hackett Health is a functional nutrition practice — which means we investigate before we prescribe.

"Every protocol we build starts with data — your labs, your history, your symptoms. Not a template."

Investigation first. No templates. A plan personalized to your results and your life — so the changes you make actually hold.

The Process

How We Work Together

🔬
01

Functional Lab Testing

We order the tests your doctor doesn't run — gut microbiome, full hormone panel, organic acids, mineral analysis — to find what's actually driving your symptoms.

🎯
02

Root-Cause Protocol

Based on your results, we build a personalized protocol: targeted nutrition, therapeutic supplements, lifestyle adjustments — nothing generic.

🤝
03

Ongoing 1:1 Support

You work directly with Jackie and her team throughout your 4-month program. Regular check-ins, lab reviews, and protocol adjustments as your body responds.

The Foundation

The Gut Is the Starting Point

Gut health is the foundation of everything — hormones, thyroid, metabolism, mood, immune function. When the gut is dysregulated, everything downstream is affected. That's why we almost always start there.

Who We Work With

We Are Very Selective

We only take on clients we genuinely believe we can help — and we're honest when we're not the right fit. Our program is intensive, personalized, and requires real commitment. It is not for everyone.

You are a good fit if:

  • You've been dealing with symptoms for months or years and are done with band-aid solutions
  • You're willing to run functional labs and follow a personalized protocol
  • You want to understand your body — not just be handed a prescription
  • You're ready to invest in your health as a priority, not an afterthought
  • You want a practitioner who will actually look at your full picture

COMMON QUESTIONS

What You're Probably Wondering

What is functional nutrition? +
Functional nutrition looks for the root cause of your symptoms instead of just managing them. Rather than treating fatigue, bloating, or hormonal issues in isolation, it investigates how systems like your gut, hormones, and metabolism interact, uses advanced lab testing to find what is actually driving how you feel, and builds a personalized plan around your results.
How is Hackett Health different from a regular dietitian or my doctor? +
Conventional care is built to diagnose and treat disease, and it is essential for that. Hackett Health works alongside it, focusing on the dysfunction that drives symptoms before it becomes a diagnosis. We investigate before we prescribe: running functional lab panels, reading them against optimal ranges, and building a protocol around your specific biology rather than a template.
What conditions do you work with? +
We work with women navigating gut and digestive issues (IBS, SIBO, bloating), hormonal concerns (PCOS, PMS, irregular cycles, fertility), thyroid dysfunction including Hashimoto's, metabolic and blood-sugar issues, disordered eating, and nervous-system symptoms like chronic stress and burnout. If your diagnosis is not listed, the investigative approach is the same.
Do you work with clients virtually? +
Yes. Hackett Health works with clients virtually, so you can do the program from wherever you are.
How long is the program? +
The core program runs four months. You work directly with Jackie and her team throughout, with regular check-ins, lab reviews, and protocol adjustments as your body responds. Root-cause work takes time to do properly, and the length is what makes the results hold.
How much does it cost? +
Because every plan is personalized to your testing and situation, pricing is discussed on your free strategy call rather than listed as a flat number. The call is where you find out what working together would actually involve for you.
Do you take insurance? +
Some clients are able to use insurance for nutrition coaching through Berry Street, and HSA/FSA funds are often eligible. The strategy call is the best place to confirm what applies to you.
