Fish oil may impair brain function in people with repeated head injuries

Fish oil supplements, long promoted as brain-healthy, may actually harm people who've had repeated mild head injuries. Researchers found that EPA, an omega-3 fatty acid in fish oil, can 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.
