Clinical Pharmacokinetics: Magnesium L-Threonate vs. Bisglycinate on Blood-Brain Barrier Penetration & Sleep
Magnesium L-Threonate (Magtein®) is the only chelate clinically demonstrated to cross the blood-brain barrier and significantly elevate cerebrospinal fluid (CSF) magnesium concentrations (+15%), enhancing synaptic density and NMDA receptor plasticity.
