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