MMS stands for a variety of product names, most commonly Miracle Mineral Solution.
MMS typically describes a solution containing the chemical sodium chlorite, which at high strengths is used as a bleach.
The term Chlorine Dioxide Solution (CDS) is also used to refer to sodium chlorite solutions. Weaker solutions have also been marketed as Aerobic Oxygen.
Sodium chlorite does have approved uses in some countries as a surface cleaner for areas used for food preparation.
It can sometimes be described as food grade but this should not be taken to imply that it is safe for consumption. It is also frequently marketed as a water purification chemical.
The aim of both products is to release chlorine dioxide gas, which is sometimes claimed to have a purifying effect when it takes place inside the body.
Danger to health
Sodium chlorite products vary in concentration, specific dosage and method of ingestion.
With products of weaker strength, any health impact from consuming these products is likely to be gastrointestinal irritation.
For stronger products, the effects can be severe nausea, vomiting and diarrhoea, potentially leading to dehydration and reduced blood pressure.
If the solution is diluted less than instructed, it could cause damage to the gut and red blood cells, potentially resulting in respiratory failure.

Legal status of sodium chlorite
Sodium chlorite is not an authorised food additive in the UK. Advertising this product as suitable for this purpose contravenes retained Regulation 1333/2008, as amended by The Food Additives, Flavourings, Enzymes and Extraction Solvents (Amendment etc.) (EU Exit) Regulations 2019.
If the product is added, for example, to a glass of water to purify it, it would need to be listed as an authorised additive.
If it is intended to be consumed by drinking, the product may be classed as an ‘unsafe food’ as defined under retained Regulation 178/2002, as amended by The General Food Law (Amendment etc.) (EU Exit) Regulations 2019. Food business operators are obliged to remove unsafe food from the market. Food can still be classed as having been placed on the market if it is offered for free or in return for a donation. This is sometimes the case with sodium chlorite solutions such as MMS.
