Researchers from the University of Texas, Arlington, recently tested and compared a number of DMAA-containing dietary supplements against commercially available geranium extracts, and detected no presence of the controversial substance in the geranium samples. The source of DMAA is a hot button issue as of late, because it could ultimately determine the outcome of a string of class action lawsuits filed against DMAA manufacturers and distributors. According to the U.S. Food & Drug Administration (FDA), DMAA is “not a dietary ingredient and is not, therefore, eligible to be used as an active ingredient in dietary supplements.”

What’s the problem?
July 16, 2012 – For the study, which was titled 1,3-Dimethylamylamine (DMAA) in supplements and geranium products: natural or synthetic?, researchers tested 13 dietary supplements containing DMAA, plus eight commercial geranium extracts. The team was led by Dr. Daniel W. Armstrong, a professor of chemistry at the University of Texas, Arlington.
After examining the geranium samples with performance liquid chromatography and mass spectrometry, Armstrong’s team was unable to identify any DMAA with a limit of detection of 10 parts per billion. The composition of the supplements, which included USPLabs’ best-selling Jack3d and Nutrex Research’s Hemo Rage, was determined by chiral gas chromatography (CG). The researchers ultimately concluded that the stereoisomeric ratios of DMAA in the synthetic standards and in all the commercial supplements were ‘indistinguishable.’
The authors conclude: “It appears unlikely that the DMAA in supplements originates from natural sources such as geranium oils for three reasons:
- The DMAA extracted from these supplement products had diastereomeric ratios that were indistinguishable from the synthetic DMAA standards;
- They are all racemic;
- No DMAA was detected at a level of ≥10 ppb in any of the 8 geranium oil samples.”
Armstrong’s research is important because it strengthens the FDA’s assertion that DMAA is synthetically-derived and does not, in fact, come from the geranium plant. Determining the substance’s source could be key to the outcome of numerous class action lawsuits filed against supplement manufacturers since the FDA sent warning letters to 10 different companies dealing in DMAA in April. If, on the other hand, it is ultimately determined that DMAA is indeed derived from geranium extract, these firms will have the leverage to argue that the ingredient is a lawful dietary ingredient, as it is a synthetic copy of something found in nature that has been in the food supply for years.
However, reliable scientific evidence backing this claim is scant at best. According to a 1996 study conducted by Chinese researchers reportedly using gas chromatography-mass spectrometry (GC-MS) techniques and published in the Journal of Guizhou Institute of Technology (1996, Vol. 25, pp. 82-85), the highly questionable ‘Ping Paper’ found that DMAA is a constituent of geranium oil. But aside from Ping, no other published analysis has backed this claim.
The one remaining hope for DMAA manufacturers now lies with USPLabs, which claims to be in possession of credible scientific research that backs Ping’s findings. While the company is still mysteriously holding back the results of the study, it has already cited the research as proof that the DMAA in their products is legal.
A USPLabs spokeswoman said that a new study in the journal Analytical Chemistry Insights titled ‘Identification and Quantification of Dimethylamylamine in Geranium by Liquid Chromatography Tandem Mass Spectrometry’ would be “released within the week.”
The new research, she claims, “definitively demonstrates the presence of DMAA in geranium.” She added: “We continue to work with the FDA to confirm that DMAA is a nutritional supplement. USPlabs continues to stand by the safety and efficacy of our DMAA products, and our customers worldwide continue to purchase and enjoy them.”
