What it looks at
- Symptoms count less than circumstances. Fatigue fits almost everything; heavy periods, a vegan diet or long-term omeprazole say much more.
- A nutrient appears only when at least one symptom and at least one risk factor point to it.
- The result is a list of tests to discuss, with their pitfalls, never a diagnosis and never a dose.
