At the screening visit for subjects taking a statin drug, the study will be described and consent to enroll will be obtained but no bloodwork will be performed. Subjects will be given an encapsulated placebo to take for an 8 week washout period. At the second screening visit, blood will be drawn to ascertain baseline laboratory values as described above for subjects not on a statin drug. The subject will then be scheduled for their first study visit 2 weeks later.
