Resveratrol for Cerebrovascular Health
CResearch suggests resveratrol may improve cerebral blood flow through nitric oxide-mediated vasodilation and activation of neuroprotective SIRT1 pathways. Bioavailability remains a key challenge.
The Bottom Line
Research suggests resveratrol may improve cerebral blood flow through nitric oxide-mediated vasodilation and activation of neuroprotective SIRT1 pathways. Bioavailability remains a key challenge.
