Due to the high prevalence of use of dietary supplements in the population it has become critical that both food and supplemental sources of nutrients be ascertained as part of dietary intake assessment. In response to this need a dietary supplement assessment module has been added to the Nutrition Data System for Research (NDSR) software. The module is designed for use in conjunction with the software's 24‐hour dietary recall collection features. A demonstration study was conducted to evaluate, among other things, practical considerations in collecting supplement use information using the tiered assessment approach incorporated into the program. Results indicate that it is possible to collect supplement use information in conjunction with both scheduled in‐person 24‐hour dietary recalls and unannounced telephone dietary recalls. However, the time required to collect supplement information varies greatly, from as little as a few minutes for those who use just 1 or 2 common products to as much as 40 minutes for those using many (e.g. 10 or more) products. These results have implications for those designing studies where assessing nutrient intake from both food and supplemental sources is of importance. In particular, consideration may need to be given to how to streamline the process for those using a large numbers of products. Fortunately most supplement users do not fit into this high use category.
