Description

Summary

The objective of this project is to evaluate the postprandial serum and plasma vitamin and mineral levels in healthy adult men and women between 18 and 32 years of age, following a single intake of a multivitamin and mineral supplement processed in two different ways.

Official Title

Patterns of Plasma Vitamins and Minerals Following Intake of a Multivitamin/ Mineral Formula Produced by Two Different Manufacturing Processes

Details

Serum or plasma levels of five vitamins and four minerals will be measured at baseline, and 1, 2, 4, and 6 hours after the intake of a multivitamin/mineral supplement processed by two different methods. The two methods involve using either conventional isolated vitamins and minerals blended together to provide approximately 100% of the Daily Value, or using the same amount of vitamins and minerals that have first been processing into liposomal forms before blending. Participants are required to come for two study visits which are 5 to 7 days apart. Health screening will also be done at Study Visit 1. The order of supplement assignment will be randomized, performed in a double-blind manner.
