Ecklonia cava exerts its therapeutic effects primarily through its rich content of phlorotannins, particularly dieckol, 6,6′-bieckol, and phlorofucofuroeckol. These marine polyphenols demonstrate potent antioxidant, anti-inflammatory, and neuroprotective activities through multiple molecular pathways including Nrf2 activation, NF-κB inhibition, and direct free radical scavenging.

Absorption: Moderate oral bioavailability (15-30%)

Distribution: Wide tissue distribution, crosses blood-brain barrier

Metabolism: Hepatic metabolism via phase II conjugation

Elimination: Primarily renal excretion, half-life 4-8 hours

Antioxidant Effects: Linear dose-response up to 800mg daily

Anti Inflammatory Effects: Significant effects at 400mg daily

Cognitive Benefits: Optimal effects at 600-800mg daily

Metabolic Effects: Dose-dependent up to 1000mg daily

Ecklonia cava dosing is well-established through clinical trials, with standardized extracts containing 10-30% phlorotannins typically dosed at 400-800mg daily. Dosing varies by specific health goals, with cognitive benefits requiring higher doses than general antioxidant support.
