available science on safe levels of caffeine consumption in foods, beverages, and dietary supplements and to identify data gaps. See Box 1-1 for a detailed list of specific workshop objectives. Workshop participants included scientists with expertise in food safety, nutrition, pharmacology, psychology, toxicology, and related disciplines; medical professionals with pediatric and adult patient experience in cardiology, neurology, and psychiatry; public health professionals; food industry representatives; regulatory experts; and consumer advocates.

The information presented in this workshop summary reflects only what was spoken or visually presented (on slides) during the workshop. Although this workshop summary covers a range of subject matter, it should not be construed as a comprehensive review of the subject matter. Nor should any of the information, opinions, or conclusions expressed here be construed as reflecting consensus on the part of the IOM, the Food and Nutrition Board, the Board on Health Sciences Policy, the workshop planning committee, or any group. The purpose of the workshop was to engage in a dialogue about the safety of caffeine in food and dietary supplements, including, but not limited to, caffeinated beverage products, and to identify data gaps, not to reach consensus on any issue or to make recommendations. All the opinions, interpretations, and suggestions for future research summarized in this document reflect the opinions of individual workshop participants.

Equally important, although much of the workshop discussion revolved around the science of the safety of caffeine in energy drink beverages, the intended scope of the workshop discussion extended across all foods and beverages, as well as dietary supplements, and included coffee, tea, carbonated soft drinks, and numerous other types of products. Also, as the planning committee chair Lynn Goldman emphasized in her welcoming remarks, the workshop was intended to cover only the assessment of potential health risks associated with caffeine exposure (i.e., risk assessment), not the management of those risks (i.e., risk management).
