Dietary Supplement Label Database (DSLD) This link opens in a new windowDietary Supplement Label Database (DSLD) captures information on dietary supplements' labels and allows the searching, sorting, and filtering capabilities needed by researchers. Its data can be saved and analyzed. It is a significantly larger effort than the current NLM Dietary Supplements Labels Database and already contains 17,000 labels and images of labels. It is expected to grow rapidly over the next three years, eventually covering most of the 55,000 dietary supplement products sold to American consumers.
