The aim of this study is to determine the effect of wheat germ oil (WGO) compared with groundnut oil (GNO) and mixed micelles (control) on lutein bioavailability and bioactivity in mice. The choice of carrier lipid is critical to achieve an enhanced bioavailability of lutein. ⋯ The increased lutein bioavailability in the WGO group compared with the other two groups may be attributed to the polar lipids and intestinal lipase activity found in this study. The results imply a new insight into the application of WGO for improving lutein bioavailability.
