Popular brain supplement could have an unexpected downside, researchers warn

A new study suggests that EPA, a key omega-3 in fish oil, may hinder brain self-repair after injury. Mice fed EPA showed impaired cognitive function and increased toxic tau protein buildup, a marker for brain degeneration. These findings, observed in human CTE tissue, raise concerns about EPA's role in brain health.
