RT Journal Article SR Electronic T1 Fish oil supplementation: Evidence for health benefits JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 208 OP 221 VO 71 IS 3 A1 Harris, William S. YR 2004 UL http://www.ccjm.org/content/71/3/208.abstract AB Many health claims for fish oil (which contains omega-3 fatty acids) in conditions from Alzheimer disease to Zellweger syndrome are based on indirect evidence. But the evidence is direct for a benefit in coronary heart disease prevention, and the American Heart Association recently issued guidelines for the intake of omega-3 oils. This article answers a series of questions that health care professionals often ask regarding fish oil, such as what are proper dosages, and are there risks of ingesting pollutants by eating more fish or using supplements?
