Fish oil's EPA may hamper brain repair after repeated head injuries
A study, largely in mice, suggests long-term EPA from fish oil can destabilize brain blood vessel walls and block repair signals after repeated mild head injuries, while promoting tau buildup. Researchers caution that the findings may not directly translate to humans and that fish oil’s effects are context-dependent, underscoring the need for more research on its risks and benefits especially for those at risk of brain trauma.
