Expertise · clarity · boundaries

About Siff Frost

Functional medicine meets real-life implementation — with a calm, structured process built for people who want clarity, not guessing.

Background

I’m a Functional Medicine Practitioner and Naturopathic Doctor (MSc.) with a specialization in gut health and the microbiome. I’m also trained in herbodietics and homeopathy, certified as a Nutritionist, and educated as a Nurse Assistant.

That combination gives me one advantage: I can translate complex data into a clear next step — without drowning you in theory.

Works best for
  • Complex gut patterns + fatigue / brain fog
  • Hormone + stress-load patterns (peri/menopause, thyroid-related)
  • Inflammation, immune patterns, stubborn weight
  • People who want structure, not “try this” advice

How I work

I don’t do generic protocols. I work with a paid, structured process that protects your time and your nervous system: first we select the right test, then I interpret results systemically and give you a clear direction.

  • GI-MAP — microbiome, pathogens, inflammation markers
  • DUTCH — hormone metabolites + stress markers
  • Organic Acids — metabolism patterns + nutrient pathways

What you get

Not more information — clarity. You’ll know what matters, what doesn’t, and what to prioritize first.

  • Context: results explained in plain language
  • Priority: what to address first (and what to ignore)
  • Direction: next steps that are realistic to implement

How I Work

No guessing. No generic protocols. We start with a short intake to select the right test — then I interpret your results systemically and give you a clear direction.

The process
1

15-minute intake & test selection

A short call to understand your main pattern and select the most relevant functional test — so you don’t waste money on the wrong data.

2

Lab testing (ordered after the call)

GI-MAP, DUTCH or Organic Acids — chosen for your case. Results typically arrive in ~2–3 weeks.

3

60-minute results review

Interpretation + priorities + next steps. You leave with clarity and a realistic direction — not a generic template.

Why it works
  • Systemic clarity: we connect gut, hormones, stress response and metabolism
  • Precision: we choose the right data first
  • Boundaries: paid, structured process — no “free calls”, no guesswork
Who this is for
  • Persistent gut issues (bloating, IBS patterns, reflux, dysbiosis)
  • Hormone shifts (peri/menopause, PMS, thyroid-related patterns)
  • Low energy, brain fog, sleep issues
  • Stubborn weight + inflammation patterns
A note on tools

When appropriate, I may integrate evidence-based supplements and natural tools (herbs / essential oils). Everything is selected to fit your data and your tolerance — not trends.
