Omega-3 Fatty Acids (DHA/EPA) for Cerebrovascular Health
B Good Evidence At least one randomized trial supports this, with mostly consistent results.DHA supports vascular endothelial function and may help reduce neuroinflammation. In CAD patients, 3.36 g/day supplementation was associated with slowed cognitive aging equivalent to approximately 2.5 years.
The Bottom Line
DHA supports vascular endothelial function and may help reduce neuroinflammation. In CAD patients, 3.36 g/day supplementation was associated with slowed cognitive aging equivalent to approximately 2.5 years.
