by Life Extension
"2000mg Magtein magnesium L-threonate — the only magnesium form clinically shown to cross the blood-brain barrier for cognitive support"
Overview
Life Extension Magnesium L-Threonate provides 2000mg of Magtein (magnesium L-threonate) per 3-capsule serving, yielding 144mg of elemental magnesium. Magnesium L-threonate is the only form of magnesium clinically demonstrated to cross the blood-brain barrier and increase brain magnesium levels. Developed at MIT, Magtein was shown in human trials to reverse brain aging by an average of 9 years as measured by cognitive testing. The mechanism involves increasing synaptic density and NMDA receptor function in the hippocampus and prefrontal cortex — regions critical for learning, memory, and executive function. The 90-capsule count provides a 30-day supply.
