<qa>  What will subjects be served identical meals at the same timepoints as in the baseline phase?Post-MT CYP profile: Subjects will return to the GCRC for this phase of the study. Subjects will check in the morning prior to a repeat dosing of probe medications. The profiling of CYP3A4, CYP2D6 and CYP1A2 will be performed exactly as described for the baseline phase with the exception that for the first 24 hours subjects will continue their previous schedules of dosing with the MT supplement. The doses of probe drugs will coincide with the 8AM dose of MT so that they will be taken concomitantly. Blood and urine sampling times will be identical. As in the baseline phase, subjects will be in a fasted state for 4 hours following probe drug administration. Additionally, subjects will be served identical meals at the same timepoints as in the baseline phase.
