Fish oil (dha plus epa) works better than statins at improving hdl cholesterol

Fish Oil (DHA plus EPA) Works Better Than Statins at Improving HDL Cholesterol A study has shown that fish oils are more effective than the statin drug Lipitor in positively affecting the levels of HDL ("good") cholesterol in obese and insulin-resistant people. HDL cholesterol protects against atherosclerosis by removing excess cholesterol from arterial cells, and low HDL levels can t
