While the benefits of omega-3 fatty acids have been known for decades, particularly in reducing cardiovascular disease risk, there has been scientific uncertainty about whether fish oil supplementation might increase LDL (sometimes called "bad") cholesterol.
An article set for publication in the Journal of Clinical Lipidology (available online now) suggests that worry might be unnecessary. The authors, based on this study of almost 10,000, mostly male, participants, conclude that "initiating fish oil supplement use did not increase LDL-C."
