Coenzyme Q-10 · 400 mg

CoQ10 has limited support for changes in blood pressure, blood lipids or blood-vessel function in adults with abnormal blood lipids. This serving provides 400 mg of ubiquinone, above that trial’s 120 mg amount, without establishing proportionately greater benefit. The findings concern selected cardiovascular markers and do not establish prevention of heart attacks or strokes or an added cardiovascular benefit from piperine.
