Abstract
Dietary supplements are typically ingested by customers who already have a well-balanced diet and an awareness of a personal, specific deficiency or fitness goal serving as their reason for doing so. Accordingly, the accuracy of the composition of a supplement on its label is paramount in determining if said tablets are worthwhile for customer use. A method was developed to determine the accuracy of the nutrition facts labels on two different brands of iron and zinc supplements. Samples were prepared via dissolution in nitric acid followed by filtration, dilution and analysis via flame atomic absorption spectroscopy. A standard curve method was used. Results of experimental trials were analyzed against the standard curves developed and results were compared to the manufacturers’ labels.
