A specialist practice, by design

I work with a narrow set of problems —
so I can solve them exceptionally well.

This practice is right for you if

  • You have persistent GI symptoms — bloating, gas, reflux, constipation, diarrhea, abdominal pain — that haven’t resolved with standard care
  • You suspect or have been diagnosed with SIBO, IMO, IBS, dysbiosis, or another microbiome disorder
  • You’ve seen gastroenterologists, tried diets and supplements, and still don’t have durable answers
  • You’re willing to complete functional testing and follow a sequenced, multi-month protocol
  • You are willing and ready to modify your diet and commit to a customized nutrition plan for long-term results
  • You want a clinician who works from data — not a cheerleader with a meal plan

It’s not the right fit if

  • You’re looking for general weight loss or body-composition coaching
  • You want a quick supplement recommendation or a single one-off session
  • You’re resistant to making dietary changes or adhering to a structured nutrition protocol to support your clinical data
  • You’re not ready to invest in testing and a structured clinical program
  • Your primary concern is unrelated to gastrointestinal or microbiome health

If that’s you, I’m happy to point you toward practitioners who focus on exactly those things — just ask when you reach out.

The Analytical Nutrition Method

Five phases. One order.
Because sequence is the difference between healing and flaring.

Most gut protocols fail not because the interventions are wrong, but because they’re done in the wrong order. My method identifies your specific imbalances, then corrects them in the sequence your biology requires.

Phase 01

Comprehensive case analysis

A 75-minute clinical intake covering your full history, diet, prior labs, and symptom timeline. Complex cases deserve real time.

Phase 02

Targeted functional testing

Breath testing, comprehensive stool analysis, and additional labs — selected for your case, never a standard panel.

Phase 03

Sequenced protocol design

Your imbalances, mapped and prioritized. Every intervention placed in the order that compounds results instead of triggering setbacks.

Phase 04

Guided implementation

Structured follow-ups plus direct text and email access to Nicole between sessions. You are never guessing alone.

Phase 05

Reassessment & durability

Retesting where warranted, and a maintenance plan designed so results hold long after the program ends.

“Making changes in the wrong order is rarely effective — and often makes symptoms worse.”

That single insight, drawn from sixteen years of clinical practice, is the foundation of everything this practice does. Sequencing isn’t a detail. It’s the method.

Conditions I specialize in

Deep expertise in the disorders
most practices only dabble in.

SIBO

Small intestinal bacterial overgrowth — hydrogen and hydrogen-sulfide patterns, including relapsing cases.

IMO

Intestinal methanogen overgrowth, the methane-dominant pattern behind stubborn constipation.

Learn more →

IBS

Root-cause workup for IBS-C, IBS-D, and mixed presentations — beyond symptom management.

Learn more →

Dysbiosis

Microbiome imbalance driving bloating, irregularity, skin issues, and systemic inflammation.

Learn more →

Reflux & GERD

Persistent reflux that hasn’t responded to acid suppression — addressed at the cause.

Learn more →

H. pylori

Testing-guided nutritional support before, during, and after eradication.

Learn more →

Histamine intolerance

The gut-histamine connection behind reactive, “random” food symptoms.

Learn more →

Intestinal permeability

“Leaky gut” evaluated with real markers — and restored with a staged protocol.

About Nicole Visnic, CNS®

A clinician’s clinician —
sixteen years in complex GI care.

I spent most of my career inside an Integrative Medical Clinic in Santa Monica, working shoulder-to-shoulder with physicians on the cases nobody else could crack — chronic fatigue, functional gastrointestinal disorders, and stubborn microbiome imbalances. That’s where I learned that lasting results come from analysis, not templates.

I founded Analytical Nutrition to bring that clinic-grade rigor to a private practice: a limited caseload, advanced functional testing, and protocols sequenced to each client’s biology. No generalized gut-health diets. No guesswork.

Working together

Private-pay, by design.

I don’t accept insurance — deliberately. A private-pay practice lets me keep a limited caseload, spend real clinical time on every case, and remain accountable only to your results, not an insurance company’s reimbursement codes.

Programs are structured multi-month clinical engagements that include your comprehensive analysis, protocol design, follow-up consultations, and direct access to me between sessions.

Apply for a consultation

Do you accept insurance?

No — my practice is private-pay by design. It’s what allows a limited caseload, unhurried clinical work, and accountability to your outcome rather than to reimbursement codes. Many clients successfully use HSA/FSA funds; I can provide documentation on request.

What does a program cost?

Programs range from $2,000 to $4,000 and run three to six months depending on case complexity. Functional lab testing is billed separately through the lab. Exact scope and pricing are confirmed after your case review call.

Do we meet in person or virtually?

All consultations are conducted virtually, which lets me work with clients throughout California and nationwide. Sessions are personal, unhurried, and conducted over your preferred platform.

Are supplements included?

Supplements are recommended per-protocol and purchased separately through a professional-grade dispensary at a significant discount — you’ll never be sold a one-size-fits-all stack.

How do I know if this is right for me?

If you have persistent GI or microbiome-related symptoms and you’ve already tried the standard routes without lasting results, you’re likely a strong fit. The application below takes five minutes and tells us both quickly.
