Depending on who you ask, the same liquid is industrial bleach, a poison, or a treatment. That contradiction has documents behind it — and almost nobody has read them. This site gathers them: 32 claims circulating online, each with its verdict — false, partly true, not supported — and the paper that sustains or refutes it. We are not asking you to believe us. We are asking you to open the source.
| What is claimed | Verdict | Why |
|---|---|---|
| CDS is bleach. | FALSE | Bleach is sodium hypochlorite (NaClO), alkaline and caustic. CDS is chlorine dioxide (ClO₂) dissolved in water: neutral, no sodium. Three different substances, confused daily. |
| The FDA records deaths from drinking it. | NOT SUPPORTED | The FDA public file holds eight reports under “chlorine dioxide”: none with a dose, none with a verified substance, and none is a death. |
| It damages the thyroid and neurodevelopment. | PARTLY: HIGH CONTINUOUS DOSE IN ANIMALS | In monkeys, at 100–200 mg/L in drinking water, a reversible T4 depression was measured. At the protocol concentration there is no data for that effect. |
All 32 are in the full register, each with its source and the query to reproduce it.
The one-line summary: it is proven to be a potent disinfectant and to be tolerated orally at the doses studied; it is not proven to cure any disease. That distinction is the whole site.
| It is | It is not |
|---|---|
| A register of claims with verdicts and primary sources | A shop selling any product |
| An archive that keeps copies of the documents it cites | An opinion blog or a news feed |
| A site that publishes its own corrections | Medical advice: nobody is told what to take |
| A project with declared conflicts of interest | An independent source: the protocol's author funds its upkeep |
Public argument about chlorine dioxide is conducted almost entirely through press releases. The primary documents — the toxicological profile, the environmental risk assessment, the adverse-event database, the judgments — are cited second-hand, if at all. This site puts them in one place, with the figures taken directly from them and the queries written out so that anyone can repeat the check.
