Fish oil may be hurting your brain, new study finds

3 hours ago

Fish oil, often promoted as brain-protective, may impair recovery in individuals with repeated mild head injuries.
A key omega-3 fatty acid, EPA, is linked to weakened blood vessel repair, disrupted healing signals, and harmful protein buildup.
The study found EPA, but not DHA, reduces repair capacity in brain cells and is associated with cognitive decline in animal models.
In human CTE brain tissue, patterns of disrupted fatty acid balance and vascular instability align with EPA-related vulnerabilities.
Researchers caution against universal conclusions, emphasizing context-dependent effects and the need for precision nutrition approaches.
The findings highlight the importance of understanding long-term omega-3 supplement effects, especially for those with brain injury risks.
