Magnesium may Boost Memory Yet Deficiency is Common

Dark green leafy vegetables and fish have magnesiumHalf the population of the industrialized countries has a deficiency in magnesium. A deficit in this important mineral has been linked with allergies, asthma, attention deficit disorder, anxiety, heart disease, muscle cramps and other conditions.  And now researchers are finding evidence that magnesium may also play an important role in memory and learning.

In a recent study from the Massachusetts Institute of Technology, mice given extra doses of a new magnesium compound had better learning abilities and working memories. This is an interesting study in that it provides evidence that a magnesium deficit may lead to decreased memory and learning ability, while an abundance of magnesium may improve cognitive function. The findings, described in the Jan. 28 issue of the journal Neuron, are early however.  Before we start taking magnesium supplements, more research needs to be done. 

It’s good to keep in mind, however, that the average adult needs to consume between 300 and 400 milligrams of magnesium a day from magnesium-rich foods such as dark green leafy vegetables.
