Overview

Life Extension Neuro-Mag provides 2000mg of Magtein (magnesium L-threonate) per 3-capsule serving, delivering 144mg of elemental magnesium. Magnesium L-threonate was developed at MIT and is the only form of magnesium clinically demonstrated to cross the blood-brain barrier and increase brain magnesium levels. In clinical trials, Magtein improved cognitive function, memory, and sleep quality in older adults. The mechanism involves enhancing synaptic density and NMDA receptor signaling in the hippocampus and prefrontal cortex.
