DMAA… where to begin?
In April, the FDA issues warning letters against a number of companies alleging that the DMAA in their products is synthetic and not allowed for use in dietary supplements. We then had a couple more studies that failed to find DMAA in geranium, including one study described by many industry observers as the ‘final nail in the DMAA coffin’.
In a classic counter, USPLabs has funded a couple of studies of its own that claim to prove the existence of DMAA in plant material.
The most recent study offered an explanation as to why so many studies have failed to find the controversial ingredient in geranium plant material – it’s only found in geranium from very select sites within China!
The study, published in Analytical Chemistry Insights, claimed: “Until now, none of the samples analyzed have been identical or reported as from the same region.
“Thus, regional environmental variations could explain the presence of 1,3-DMAA in the Changzhou S11, Changzhou March 2012, and Changzhou May 2012 samples and the absence of 1,3-DMAA concentrations in Kunming and Guiyang geranium samples reported here, [and samples reported elsewhere].”
Repetition of the results observed in these Changzhou samples by other laboratories is urgently needed.
