About

A melatonina é um neurormônio que regula o ritmo circadiano, fundamental para a consolidação da memória durante o sono. Apoia a função cognitiva ao promover a depuração do sistema glinfático de beta-amiloide e resíduos metabólicos, além de atuar como potente antioxidante cerebral, protegendo os neurônios do estresse oxidativo.

How It Works

Regulates circadian rhythm critical for memory consolidation; potent antioxidant that scavenges reactive oxygen species in the brain; modulates GABA-A receptors; supports glymphatic clearance of beta-amyloid during sleep.
