MMS (chlorine dioxide) for autism: why it's dangerous for a child

MMS, or "Miracle Mineral Solution," is sometimes offered to parents as a treatment for autism, on the claim that it "removes parasites" or "toxins" supposedly causing autism. This is the rare case on this list where the research doesn't even need reviewing: MMS is, in effect, a bleaching agent, and that's exactly how health regulators officially describe it.

What this substance actually is

MMS is a solution of sodium chlorite that's mixed with an acid, such as citric acid. The result is chlorine dioxide, a chemical compound used industrially to bleach paper, pulp, and textiles. Children are given this to drink or, in some protocols, as an enema. The US Food and Drug Administration (FDA) issued a specific warning about this product and put it plainly.

The FDA lists documented effects directly: nausea, vomiting, severe diarrhea, signs of serious dehydration, and in some cases, liver problems. No scientific evidence exists for MMS being effective for autism or any other condition, only marketing claims from sellers.

It went to court

In the US, sellers of MMS weren't just warned, they were prosecuted. A federal court found the leaders of an organization that sold MMS as a "miracle cure" (including for autism) guilty of fraud, and they received actual prison sentences. This wasn't treated as ordinary misleading advertising: authorities handled the sale of this substance as the sale of a dangerous and illegal product.

What to do if someone offers you MMS

• Don't give a child MMS in any form, not orally, not as an enema. This applies to any product under similar names: Master Mineral Solution, MMS, Chlorine Dioxide Protocol, Water Purification Solution (WPS).
• The idea of "parasites" or "toxins" causing autism isn't supported by science. It's a marketing explanation, not a medical fact.
• If a child has already been given MMS and has vomiting, diarrhea, or signs of dehydration, seek medical care rather than waiting for it to pass on its own.
• If someone offers you MMS under any name, you can report it to local health authorities, this isn't just an ineffective method, it's an illegal and dangerous product.

What we offer instead

MMS is an extreme, but not the only, example of a method sold to desperate parents on nothing but promises: if you'd like the bigger picture on other alternative methods, we've covered a large scientific review of 19 of them in a separate article: Myths about autism treatment. Unlike MMS, applied behavior analysis (ABA) doesn't interfere with a child's body chemistry, it changes what and how a child learns, and that's been tested in dozens of controlled studies.

You can start with a free thirty-minute consultation, where we'll talk honestly about which of the methods offered to you are backed by research and which aren't.
