Rating (out of 5): 3

DHA (docosahexaenoic acid) is an omega-3 fatty acid abundantly found in the brain and is essential for normal neurological function. Scientific interest in DHA for supporting cerebral circulation and cognitive health is based on both mechanistic and epidemiological evidence. DHA is incorporated into neuronal membranes, where it contributes to membrane fluidity, modulates signal transduction, and may reduce neuroinflammation. Several observational studies have associated higher dietary intake or blood levels of DHA with a reduced risk of cognitive decline and improved cerebral blood flow. Furthermore, animal studies suggest that DHA supplementation can enhance endothelial function and promote vasodilation, potentially improving cerebral perfusion. Some small clinical trials have reported that DHA supplementation increases cerebral blood flow in older adults, though results are not entirely consistent and large-scale randomized controlled trials are lacking.

Overall, there is moderate scientific validation (rated 3/5) for the use of DHA to support circulation to the brain, particularly in the context of maintaining cognitive function and possibly reducing the risk of neurodegenerative diseases. However, while the mechanisms are plausible and some data are promising, more robust clinical trials are needed to conclusively determine its efficacy for improving cerebral circulation specifically. Thus, DHA is used with a reasonable scientific rationale, though it should not be considered a primary treatment for cerebrovascular insufficiency without further evidence.
