7 Aug 2012 --- The Food Standards Agency is advising people not to consume products containing the substance DMAA (1,3-dimethylamylamine), after a number of people across the world have reported adverse reactions linked to products containing DMAA.

The FSA is aware that products containing DMAA are being sold in the UK as pre-workout sports supplements and as so-called fat burning food supplements.

DMAA is a stimulant, for which a safe level for human consumption has not been established. Products containing DMAA have been withdrawn in various countries across the European Union and around the world. DMAA has been linked with high blood pressure, nausea, cerebral haemorrhage, stroke and death.

Where DMAA is present in a product it may be listed on the packaging as:

 - 1,3-dimethylamylamine
 - DMAA
 - geranium extract
 - geranamine
 - methylhexanamine
 - 4-methylhexane-2-amine

The FSA is working closely with enforcement authorities to ensure that food supplements containing DMAA are not on sale in shops. Consumers are also advised not to buy online any food supplements or products containing DMAA. If you have consumed products containing DMAA and you feel unwell, please contact your GP.
