Postdoctoral Vacancy: Research Chemist/Phytochemical Scientist Join our NIH-funded study of dietary supplements! This project supports theDietary Supplement Ingredient Database (DSID; (https://dsid.od.nih.gov/), a database for information on analytically verified dietary supplementcontent. The DSID website provides online calculators converting labeled levels into analytically derived estimates of ingredients in dietarysupplement products sold in the US. Funded by the National Institutes of Health (NIH) for over 15 years, the DSID project has a team that includes achemist, biologists, IT analysts and statisticians. The research is based on fundamental principles of public health, nutrition and analytical chemistry.For multivitamin/mineral and omega-3 fatty acid studies, dietary supplement samples are purchased according to statistically developed samplingplans for products representative of the US market. The products are sent to contracted laboratories for the analysis of ingredient content. Botanicaldietary supplements, including green tea, turmeric and cranberry products have been analyzed in smaller studies. In addition to determining how theanalytical content of supplements compares to label claims, we also assess the performance quality of dietary supplements using United States Pharmacopeia protocols for disintegration and dissolution testing.
