Quick Answer: This framework merges OneDayMD's I-PREVENT Cancer Protocol with Dr. Paul Marik and Dr. Justus Hope's ROOT Protocol into a single five-layer system. Layer 1 is diet, metabolic health, and lifestyle — the original I-PREVENT foundation. Layers 2–3 are food-derived nutraceuticals (EGCG, curcumin, vitamin D3, omega-3, berberine, sulforaphane, vitamin C, magnesium, zinc, garlic, melatonin, and more), graded from strongest human-trial evidence to broader supporting data. Layer 4 is an optional Aged Garlic Extract upgrade. Layer 5 is Root 9 — the prescription drugs celecoxib, ivermectin, and mebendazole — which both authors scope strictly to people with confirmed hereditary cancer syndromes under specialist supervision, not general use.

An estimated 40–50% of cancer cases may be attributable to potentially modifiable risk factors , although the exact proportion varies by population, cancer type, and methodology. Certain supplements—including vitamin D, curcumin, and omega-3 fatty acids —have shown promising findings in specific settings, but the evidence is considerably less consistent than fo...
