Magnesium is needed for more than 300 biochemical reactions in the body. In addition to support for cardiovascular and bone health, energy metabolism and mood, researchers are now focusing intensely on magnesium's benefits for cognitive function.* Unfortunately, it is very hard for your body to maintain optimal levels of magnesium in the brain. This problem is of special concern for maturing individuals, as magnesium deficiency increases over time. Most commercially available magnesium supplements are not readily absorbed into the nervous system. To overcome this obstacle, you can supplement with Life Extension Neuro-Mag Magnesium L-Threonate, shown to specifically target the aging brain and nervous system.
