Exclusion Criteria: Patient who has participated in other investigational studies within 3 months. Patient took medication and natural health foods known to alter blood lipid profiles within 4 weeks. Patient is taking any medication or food that is prohibited by the study. Patient taking Amiodarone will be excluded from this study (due to long half life of this medication).
