Higher circulating levels of marine omega-3 polyunsaturated fatty acids (EPA and DHA) are associated with a significantly lower risk of total and ischemic stroke, with no increased risk of hemorrhagic stroke.

Aiming for higher blood levels of EPA and DHA (specifically an omega-3 index of 8% or higher) is associated with a lower risk of stroke. This can be achieved through dietary intake of 1-2 seafood meals per week or supplementation with approximately 1000-1600 mg/day of EPA+DHA, depending on your baseline levels.
