Magnesium L-threonate: Effects in Alzheimer's disease and Oral Application

Magnesium is essential for many of the body’s processes. Magnesium deficiency in serum or the brain of Alzheimer’s disease (AD) patients has been shown to be associated with AD. Current research suggests that supplementing or restoring magnesium may be a novel approach to AD treatment. 

Magnesium threonate, or magnesium L-threonateTrusted Source, is a nutritional supplement that contains the L-threonate form of magnesium.  Magnesium L-threonate has been shown to boost brain magnesium levels in animals when taken orally. This effect is due to its unique ability to cross the blood-brain barrier.

Magnesium-L-threonate has recently been found to have protective effects on learning and memory in aged and Alzheimer's disease model mice. Magnesium-L-threonate modulated the abundance of three genera in the gut microbiota, decreasing Allobaculum and increasing Bifidobacterium and Turicibacter. We also found that differential metabolites in the magnesium-L-threonate-regulated serum were enriched in various pathways associated with neurodegenerative diseases. The western blotting detection on intestinal tight junction proteins (zona occludens 1, occludin, and claudin-5) showed that magnesium-L-threonate repaired the intestinal barrier dysfunction of APP/PS1 mice. These findings suggest that magnesium-L-threonate may reduce the clinical manifestations of Alzheimer's disease through the microbiota-gut-brain axis in model mice, providing an experimental basis for the clinical treatment of Alzheimer's disease.
