Dr. Grant Tinsley Receives Research Grant


Angela Lumpkin

Dr. Grant Tinsley, an Associate Professor in the Department of Kinesiology & Sport Management, recently received a research grant worth $159,341.00 from Nutraceutical Corporation to study whether a new form of multivitamin leads to improved nutrient absorption.  

Multivitamins are one of the most popular dietary supplement categories, with a large proportion of individuals consuming these products daily. A recent biotechnological advance in nutrient delivery is the packaging of nutrients in spherical lipid structures called liposomes. This feature may allow for enhanced absorption of target nutrients and a greater benefit to the consumer. Dr. Tinsley's study will examine whether packaging a multivitamin formulation in liposomes will improve the absorption of nutrients as compared to a traditional multivitamin preparation. 

For this study, participants will complete two visits in which they will ingest the novel liposomal multivitamin or a traditional multivitamin. Both products will be matched for nutrient content to allow a determination of whether the packaging of these nutrients influences absorption. Blood samples will be taken throughout the visit, and the absorption of major vitamins and minerals will be examined. These include vitamins A, C, D, E, B12, folic acid, magnesium, and iron. Analysis will help determine whether the concentrations and absorption patterns of these nutrients differ between the two multivitamins preparations.  

Ultimately, this research will contribute to product innovation in the dietary supplement industry and may benefit consumers of multivitamin products.
