- Mechanism of Action
- Multidentate coordination with stable metal complexes; facilitates renal excretion
- Antioxidant buffering; indirect support of Phase II detox pathways
- Endogenous induction claimed; oral bioavailability unproven
- Pharmaceutical chelators have verifiable mechanism; peptide protocols conflate antioxidant support with chelation
- Clinical Evidence
- FDA-approved for lead poisoning; provoked urine testing standard
- Limited to oxidative stress reduction; no consistent reduction in blood metal levels
- No human trials demonstrating metal excretion from supplementation
- DMSA/EDTA backed by decades of clinical use; peptide evidence is mostly in vitro
- Blood-Brain Barrier Penetration
- DMSA crosses BBB; can chelate intracellular neural mercury
- Glutathione does not cross BBB in significant concentrations
- Metallothionein molecular weight too high for BBB transport
- Only lipophilic chelators access CNS metal stores
- Provoked Urine Testing
- Standard diagnostic. Measurable metal excretion post-dose
- Rarely included in protocols; when tested, results inconsistent
- Not part of standard protocol
- Lack of provoked testing in peptide protocols is a red flag
- Cost per 30-Day Course
- $180–$320 (prescription required)
- $60–$150 (OTC supplements)
- $90–$200 (specialty formulations)
- Lower cost doesn't validate efficacy. Peptides are cheaper because they're unregulated
- Regulatory Oversight
- FDA-approved drugs; batch testing, purity standards
- Dietary supplement. No pre-market approval, variable purity
- Dietary supplement. No standardised dosing or purity verification
- Pharmaceutical oversight ensures consistency; supplement market has zero pre-market validation
