About

Resveratrol activates SIRT1 and AMPK pathways that support cellular stress resistance and enhances cerebral blood flow through nitric oxide-mediated vasodilation. Clinical evidence suggests it may improve memory and cognitive performance in older adults.

How It Works

Activates SIRT1 and AMPK pathways supporting cellular stress resistance; enhances cerebral blood flow through NO-mediated vasodilation; reduces neuroinflammation and beta-amyloid aggregation.
