Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
One tablet of multivitamin and mineral supplement to be consumed with a standard breakfast meal on one morning. Subjects will be fasted overnight prior to the intervention. The tablet will be consumed in full in the presence of the researchers to confirm compliance, to be ingested within 20 minutes. No additionally food or drink will be consumed during the 4 hour intervention. The multivitamin and mineral tablet to be consumed is Centrum Advance.
