Effects of Berry Anthocyanins on Cognitive Performance, Vascular Function and Cardiometabolic Risk Markers: A Systematic Review of Randomized Placebo-Controlled Intervention Studies in Humans

This systematic review evaluated the effects of berry anthocyanins—compounds found in fruits like blueberries and blackcurrants—on cognitive performance, vascular health, and cardiometabolic risk. Results showed improvements in memory and some enhancements in attention, psychomotor speed, and executive function. Vascular measures, such as endothelial function and blood pressure, also improved, suggesting a link between vascular health and cognitive benefits. These findings are significant for reducing age-related cognitive decline and improving cardiovascular health.

Include anthocyanin-rich berries (e.g., blueberries, blackcurrants) in your diet, aiming for fresh or minimally processed options to support memory and vascular health. While results show potential, further research is needed to confirm optimal dosages and long-term effects, especially for those without preexisting health risks.
