Root Cause Protocol

Detoxification Support

1. Root Cause Overview

The liver's detoxification system operates in two phases: Phase I (cytochrome P450 enzymes) oxidises toxins into reactive intermediates, and Phase II (conjugation reactions: glucuronidation, sulphation, glutathione conjugation, methylation) renders them water-soluble for excretion. Impaired detoxification leads to accumulation of endogenous metabolites (oestrogen metabolites, ammonia, bile acids) and exogenous toxins (pesticides, heavy metals, mycotoxins, medications). Genetic variants (CYP450, GSTM1, COMT, MTHFR) can significantly impair detox capacity.

2. Common Signs & Symptoms

  • Chemical sensitivities (fragrances, cleaning products, exhaust)
  • Alcohol intolerance or hangover sensitivity
  • Fatigue and brain fog after toxin exposure
  • Elevated liver enzymes (ALT, AST, GGT) on standard labs
  • Hormonal imbalances (oestrogen dominance, PMS)
  • Skin conditions: acne, rashes, jaundice (severe)
  • Nausea, particularly in the morning
  • Dark urine or pale stools
  • Headaches, particularly after chemical exposure
  • Poor medication tolerance (unexpected side effects at low doses)

3. Labs to Consider

STANDARD LABS

CMP, ALT/AST, bilirubin, GGT, albumin, kidney function/eGFR, CBC; toxicant testing only when clinically appropriate.

4. Clinical Priorities

Assess for potential factors increasing total toxic burden or impairing clearance, including environmental exposures, alcohol, medications, constipation, poor bile flow, nutrient insufficiency, and gut dysfunction. When support is indicated, ensure adequate protein intake, B-vitamins, and sulphur-containing nutrients, and consider sequencing detox support so clearance pathways are supported before more aggressive mobilisation strategies. Gut health also matters because the microbiome influences enterohepatic recirculation.

Where to Start: Top 2 Supplements

1st Choice
N-Acetyl Cysteine (NAC) — 600–1,200 mg/day

The most clinically validated hepatoprotective supplement. Directly raises hepatic glutathione — the primary Phase II conjugation agent. Protects against drug-induced liver injury, supports Phase II detox, and is the gold-standard for acetaminophen overdose in emergency medicine.

2nd Choice
Milk Thistle (Silymarin) — 140–420 mg/day

The most evidence-backed botanical hepatoprotective agent. Silymarin stabilises hepatocyte membranes, inhibits toxin uptake, and stimulates liver cell regeneration. Multiple meta-analyses confirm reduction in ALT/AST. Ideal first-line liver support for any detox protocol.

5. Diet Strategy

Emphasise cruciferous vegetables (broccoli, Brussels sprouts, kale) — sulforaphane and indole-3-carbinol powerfully induce Phase II enzymes. Include garlic, onions, and leeks for sulphur-containing compounds. Ensure adequate protein (1.2–1.6 g/kg/day) for amino acid conjugation. Consume beets, artichokes, and dandelion greens for bile flow support. Avoid alcohol, processed foods, and excessive fructose. Hydrate well (2–3 L/day) to support renal toxin excretion.

6. Lifestyle Strategy

Regular sweating (exercise, sauna) supports toxin elimination through skin. Ensure daily bowel movements — constipation allows enterohepatic recirculation of toxins. Minimise environmental toxin exposure: choose organic produce, filter drinking water, use non-toxic personal care and cleaning products. Dry skin brushing and lymphatic massage support lymphatic drainage. Avoid alcohol during active detox protocols.

7. Supplement Strategy

Full supplement list below. See Section 4 (Clinical Priorities) for the recommended Top 2 starting supplements. Add additional supplements based on lab results and clinical response at 4–6 week reassessment.

8. Safety Notes

Never initiate aggressive detox protocols in patients with impaired kidney or liver function — always check eGFR and liver enzymes first. Activated charcoal must be taken 2+ hours away from all medications. Aggressive detox can mobilise stored toxins faster than the body can excrete them — start low and slow. Refer for jaundice, markedly elevated liver enzymes, or suspected toxic hepatitis.
