Magnesium L-Threonate, which uses the unique, patented, chelated mineral Magtein®, contains magnesium which is chelated to threonic acid (magnesium L-threonate). It is superior to other forms of magnesium at getting through the blood brain barrier because it is able to transport magnesium ions across lipid membranes, including those of brain cells. Researchers at MIT concluded that elevating brain magnesium content via supplementation with magnesium L-threonate may be a useful strategy to support cognitive abilities and decrease common age-related memory decline.
