John Travis has more than 20 years of experience as an analytical chemist specializing in the analysis of dietary supplements. As Senior Research Scientist at global public health organization NSF International, Travis analyses hundreds of dietary supplement products each year for various contaminants, emerging drugs and harmful compounds.
Utilizing techniques ranging from gas chromatography to high-performance liquid chromatography to mass spectrometry, John has developed and validated analytical methods for numerous marker compounds and trace contaminants. He is an active member of the Association of Analytical Communities (AOAC), participating on expert review panels for Carotene and Lutein, and is a member of the AOAC stakeholder panel for Dietary Supplements.

Travis is also a subject matter expert on athletic banned substances and was instrumental in the development of the screening methods used for the NSF International Certified for Sport® program, which now screens products for more than 230 banned substances on the World Anti-Doping Agency, National Football League, Major League Baseball and National Collegiate Athletic Association lists. Travis is currently involved with the analysis of pharmaceutical agents and illicit drugs, stimulants and other prohibited substances as both adulterants and contaminants in dietary supplements and functional foods, co-authoring scientific papers on ingredients of concern including stimulants drugs DMAA, DEPEA and DMBA found in dietary supplements.

The work of John Travis and the laboratory staff at NSF International are essential to NSF''s Dietary Supplement and Certified for Sport® Certification programs, which help consumers and retailers identify safer supplements that have been analytically tested to confirm the label contents and verify that they are free of harmful drugs and many other contaminants.
