Novel Magnesium Compound Reverses Neurodegeneration
Scientists have been challenged to find a way to raise magnesium levels in the brain.8 Even intravenous infusions cause only a modest elevation of magnesium levels in the central nervous system.22
An innovative team of researchers from the Massachusetts Institute of Technology (MIT) recently found a way to surmount this obstacle. They formulated a new magnesium compound called magnesium-L-threonate or MgT that in lab tests allows for oral administration while maximizing magnesium "loading" into the brain.7,8
Based on prior research, they meticulously documented that increased levels of magnesium in the brain promote synaptic density and plasticity in the hippocampus.14 Up until now, however, no widely available forms of magnesium met the criteria needed for rapid absorption and efficient transfer into the central nervous system.8
By contrast, MgT yielded compelling results.
MgT oral supplements increased magnesium levels in spinal fluid, an index of measurement in brain magnesium by about 15%, while none of the other magnesium compounds tested produced significant elevations.8 While a 15% increase may not sound like a lot, it induced a profound effect on neurological function.
To evaluate the effects of MgT on memory, the researchers tested it against currently available magnesium compounds. They used a simple assessment of learning and memory called the Novel Object Recognition Test or NORT. A high NORT score means that the animal is good at recognizing and identifying new objects, a skill that is critical in aging humans as well.8 NORT is a good test of function in the hippocampus, which is rich in the NMDA receptors so closely controlled by magnesium.23
The researchers put aged animals through the NORT test, supplementing them with MgT or one of the commercially available magnesium compounds. Only MgT significantly enhanced both short- and long-term memory, boosting scores by 15% for short-term memory and 54% for long-term memory compared to magnesium citrate.8
