  • DNA Health: genetics and lifestyle insights
  • Hormone panels: balance, energy, metabolism

  • Chronic digestive disorders & microbiome imbalances
  • Hormonal and metabolic challenges
  • Autoimmune conditions & chronic inflammation
  • Personalized health strategies based on genetics

Mission

As a Holistic Health Coach, Siff unites science, natural medicine, and lifestyle interventions. Her mission is to create deep transformation and lasting health through insight, integration, and individual solutions.

The Siff Frost Method

We don’t guess — we test. Then we design a plan you can live with.

1

Functional Lab Testing

GI-MAP (microbiome), DUTCH hormones, Organic Acids, and targeted blood work reveal patterns across digestion, hormones, detox, and immunity.

2

Personalized Protocols

Biology-matched nutrition, targeted supplements, and natural remedies. Only high-quality products I trust.

3

Real-Life Lifestyle

Sleep, stress, circadian rhythm, movement, and nervous-system regulation — simple habits you can sustain.

Why it works

  • Root-cause clarity: testing shows what to fix first
  • Tailored plan: no generic templates
  • Accountability: check-ins and adjustments until results

Natural tools (when appropriate)

Alongside evidence-based supplements, I may integrate herbs and essential oils for gut, hormones, nervous system, and immunity.

What to expect

  • Weeks 1–2: foundations (sleep, blood sugar, digestion)
  • Weeks 3–8: targeted protocols based on labs
  • Beyond: maintain, fine-tune, build resilience

Who I help

  • Gut issues (IBS, bloating, reflux, dysbiosis)
  • Hormone shifts (peri/menopause, PMS, thyroid)
  • Low energy, brain fog, poor sleep
  • Stubborn weight and inflammation
