Fish oil may hinder brain repair after repeated head injuries, early lab study suggests

Fish oil supplements, long promoted as brain-healthy, may actually harm people who've had repeated mild head injuries. In mouse and cell experiments, researchers found that EPA, an omega-3 fatty acid in fish oil, may interfere with the brain's repair process by weakening blood vessels and disrupting healing. This interference has been linked to protein buildup associated with cognitive decline.

Fish oil may hinder brain repair after repeated head injuries, early study suggests

A new study suggests fish oil supplements may hinder brain recovery after repeated mild head injuries, contrary to their brain-healthy reputation. In mouse and cell experiments, researchers linked EPA from fish oil to weaker brain repair after repeated head impacts. If you take fish oil regularly, talk to your doctor about whether it's right for you.
