Activated Charcoal vs NAC
A side-by-side research comparison of Activated Charcoal and NAC across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Activated Charcoal | NAC |
|---|---|---|
| Full name | Activated Charcoal (Binder) | N-Acetyl Cysteine |
| Category | Detox & Antioxidant | Detox & Antioxidant |
| Status | OTC / Medical device | Dietary supplement / FDA-approved (Mucomyst) |
| Mechanism | Adsorbs toxins via van der Waals forces on its massive activated surface area. Binds mycotoxins (aflatoxin, ochratoxin), bacterial endotoxins (LPS), pesticide residues, and various organic compounds, preventing GI absorption. | Provides cysteine for glutathione synthesis (rate-limiting step). Directly scavenges free radicals via sulfhydryl group. Chelates mercury, lead, and arsenic. Modulates glutamate via system Xc- transporter for neuropsychiatric effects. |
| Molecular weight | 12.01 Da (elemental carbon) | 163.19 Da |
| Half-life | Not absorbed - passes through GI tract | ~5.6 hours |
| Bioavailability | Not absorbed systemically (GI binder only) | ~6-10% oral (poor but effective due to GSH replenishment) |
| Typical dose | 500-1000 mg | 600-1800 mg |
| Frequency | 1-2x daily away from meals/supplements | 1-2x daily |
| Route | Oral capsule or powder | Oral capsule or IV (hospital) |
