Study Summary

This study will examine whether the amount and type of fat, mono-unsaturated fat (MUFA) vs. poly-unsaturated fat (PUFA), in a meal affects the absorption of vitamin D, which is taken after that meal. The study hypothesis is that vitamin D3 absorption will be greater when fat is present vs. absent in the meal. A secondary hypothesis is that vitamin D3 absorption will be greater in the presence of a meal with a high MUFA/PUFA compared with a low MUFA/PUFA ratio.
