Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Fatty acids, particularly omega-3 polyunsaturated fatty acids (such as EPA and DHA), have been studied for their potential benefits in supporting cerebral circulation and brain health. Several scientific studies suggest that omega-3 fatty acids may support endothelial function, reduce vascular inflammation, and improve blood flow, including to the brain. Research indicates that omega-3 supplementation can enhance cerebral perfusion, possibly by reducing blood viscosity and improving vessel elasticity. Some clinical trials have shown positive associations between higher omega-3 intake and improved cognitive function, which may be partly mediated by better cerebral blood flow.

However, while there is moderate scientific support for the general vascular benefits of fatty acids, evidence specifically linking "fatty acid (unspecified)" to improved brain circulation is less robust. Most data refer specifically to omega-3 fatty acids from fish oil or certain plant sources, rather than generic or unspecified fatty acids. The strength of evidence for fatty acids other than omega-3s is limited. Additionally, while some studies have found improvement in surrogate markers of cerebral blood flow, large-scale clinical trials demonstrating significant clinical outcomes (such as reduced incidence of stroke or dementia) are still lacking or inconclusive.

In summary, there is moderate scientific evidence, mostly pertaining to omega-3 fatty acids, that supports the use of these fatty acids to benefit cerebral circulation, though further research is needed to clarify the effects and mechanisms.
