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
CMP, ALT/AST, bilirubin, GGT, albumin, kidney function/eGFR, CBC; toxicant testing only when clinically appropriate.
Choose the lab option based on what you want to assess within this root cause.

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
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.
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.
| Supplement | Dosage | Indication | Evidence | Key Results | Example |
|---|---|---|---|---|---|
| Milk Thistle (Silymarin) [1] Mild GI upset; rare allergic reactions in ragweed-sensitive patients | 140–420 mg silymarin/day in divided doses | Hepatoprotection; Phase I/II enzyme modulation; antioxidant liver support | Systematic review and meta-analysis | Significantly reduced ALT and AST in liver disease; hepatoprotective against toxin-induced damage | Thorne Siliphos (Phytosome form) |
| N-Acetyl Cysteine (NAC) [2] Nausea at high doses; avoid in active peptic ulcer disease | 600–1,800 mg/day in divided doses | Glutathione precursor; Phase II glutathione conjugation support; hepatoprotection | Clinical trials and systematic review | Increased hepatic glutathione; protective against acetaminophen and other drug-induced liver injury | Thorne NAC |
| Curcumin (phytosome or CurcuWIN®) [3] Mild GI upset; avoid in gallstone disease or bile duct obstruction | 500–1,000 mg/day | Phase II enzyme induction (NRF2 pathway); hepatoprotection; anti-inflammatory | Human RCT (NAFLD) | Significant reduction in liver fat content and BMI in NAFLD; reduced ALT/AST; NRF2 activation | Nutricology CurcuWIN 500 |
| Alpha-Lipoic Acid (ALA) [4] Mild GI upset; hypoglycaemia risk in diabetics | 300–600 mg/day | Cofactor for mitochondrial dehydrogenases; glutathione regeneration; heavy metal chelation support | Animal and human studies | Increased hepatic glutathione; improved antioxidant enzyme activity; reduced oxidative liver damage | Klaire Labs Alpha Lipoic Acid |
| Sulforaphane (from broccoli sprout extract) [5] GI discomfort at high doses; sulphur odour in urine/sweat | 10–30 mg/day (standardised sulforaphane) | NRF2 pathway activation; Phase II enzyme induction (GSTM1, NQO1, HO-1); cancer prevention | RCT and mechanistic studies | Potent NRF2 activator; significantly induced Phase II detox enzymes; reduced aflatoxin-DNA adducts | Thorne Crucera-SGS |
| Calcium D-Glucarate [6] Generally well tolerated; mild GI adjustment | 500–1,500 mg/day | Inhibits beta-glucuronidase; supports glucuronidation (Phase II); oestrogen detoxification | Animal and mechanistic studies | Reduced beta-glucuronidase activity; decreased circulating oestrogen metabolites; cancer-preventive in animal models | Pure Encapsulations Calcium D-Glucarate |
| Activated Charcoal (short-term binder) [7] Constipation; black stools; binds medications — must be taken 2+ hours away from all drugs and supplements | 1–2 g away from meals and medications | Toxin binding in GI tract; mycotoxin and chemical adsorption | Clinical and mechanistic evidence | Effective binder of mycotoxins, heavy metals, and chemical toxins in GI tract; reduced systemic absorption | Bulletproof Coconut Charcoal |
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.
