Something Fishy about Fish Oil

Monthly Newsletter

Manufacturers of fish oil supplements claim that their products can help prevent and manage heart disease, as well as protect your brain, your joints, and even your mood. But are fish oil supplements really safe to take, or can they have a negative effect on prostate cancers? Dr. Danoff reviews some recent research and gives his personal recommendation in this month’s newsletter.

Something Fishy about Fish Oil

The medical community is in the midst of a fierce debate over whether fish oil supplements are more likely to decrease or increase the risk and severity of prostate cancer. Studies in 2011 and 2013 found a higher incidence of prostate cancer among men who consumed omega-3 fatty acids, but a 2016 experimentfound that fish oil hindered the growth of prostate tumors in mice. These conflicting results have raised new questions about the safety of fish oil supplements.
