Nutritional supplements and vitamin sales continue to expand in the United States with increasing growth in both brick and mortar stores and online outlets. Regulation and oversite of these dietary supplements is limited, and it falls on the manufacturer to evaluate the safety and labeling of their products.  In this study, microwave-induced plasma atomic emission spectroscopy (MP-AES) and X-ray fluorescence (XRF) spectroscopy was used to analyze a range of commercially available nutritional mineral supplements.  Comparison of the advertised concentrations is made along with comparison of the multi-elemental quantification instrumental techniques of MP-AES and XRF spectroscopy.<br/>
