Reported Mechanism (Provisional)

Mechanism of Action

Blueberry anthocyanins activate the Nrf2 pathway, increasing antioxidant enzyme production and reducing oxidative stress. These compounds also inhibit NF-κB signaling, decreasing inflammatory cytokine production. Additionally, anthocyanins improve nitric oxide bioavailability, enhancing endothelial function and blood vessel health.

Clinical Narrative (Provisional)

A 12-week randomized controlled trial with 134 participants showed blueberry supplementation (150g daily) reduced systolic blood pressure by 4-6 mmHg. Cognitive studies with 168 older adults demonstrated improved memory performance after 12 weeks of anthocyanin supplementation (387mg daily). However, most studies use whole blueberries rather than standardized extracts, making dosage recommendations challenging.
