Summary

Research shows that resveratrol is able to induce vasodilation (and therefore blood flow) by interacting with nitric oxide (NO). Research also shows that acute administration of metabolic substrates, like oxygen and glucose, can enhance aspects of cognitive performance in young, healthy humans. The aim of this investigation was to determine if the consumption of resveratrol could modulate cerebral blood flow and if this in turn could influence cognitive performance by increasing access to blood borne metabolic fuel. Results showed that compared to placebo, after consuming 500mg pure trans-resveratrol, levels of total haemoglobin were significantly higher in the frontal cortex of young, healthy participants during cognitive task completion. Cognitive performance was not effected.

Interventions

DIETARY_SUPPLEMENT

Trans- resveratrol

All 24 participants who completed the study took part in 3 conditions; receiving either 250mg resveratrol, 500mg resveratrol or placebo on separate days (with a 48hr-14day wash out period between each treatment) with the order dictated by a latin square. Treatment was administered in capsule form and in a double blind manner.

OTHER

Placebo (silica)

All 24 participants who completed the study took part in 3 conditions; receiving either 250mg resveratrol, 500mg resveratrol or placebo on separate days (with a 48hr-14day wash out period between each treatment) with the order dictated by a latin square. Treatment was administered in capsule form and in a double blind manner.
