Do magnesium supplements, like Magtein, help memory or protect against Alzheimer's disease?
Magnesium plays an important role in brain cell function and some preliminary research in animals has suggested it may influence cognitive functions like memory and learning. A preliminary study in people found that magnesium-L-threonate (Magtein or Clarimem) may modestly improve certain measures of cognitive function. Overall, however, there is very limited evidence that taking magnesium improves memory or learning, or prevents Alzheimer's disease, in humans.
