Magnesium L-Threonate (MgT) is the most appropriate Mg salt that strengthens the cholinergic system and improves brain-related functions. It is used to improve memory, assist with sleep, and to enhance overall cognitive function. Mg, an intracellular cofactor for many enzymes, is a modulator of the N-methyl-D-aspartate (NMDA) receptor that is involved in memory function and depression. Experiments on rodents have shown that oral magnesium-L-Threonate also prevents neuropathic pain induced by chemotherapy.

Sample Use Guides

In Vivo Use Guide

When administered orally to guinea-pigs (100 mg/kg body weight) for periods of 4 or 28 days, sodium threonate (threonic acid) produced a significant fall in the ascorbic acid concentration of certain organs but was without effect on other physiological and biochemical characteristics. The lifespan of scorbutic guinea-pigs was significantly reduced by dietary threonic acid (100 mg/kg body weight)
