This chelated Magnesium is bound to L-Threonate, which is a Vitamin C metabolite. In this form it is highly bioavailable and most importantly, able to penetrate the blood brain barrier, making it a great way to deliver Magnesium for nootropic gains. The brain's need for Magnesium is very high. Magnesium threonate is magnesium bonded to a metabolite from Vitamin C called threonic acid. Threonic acid is able to cross the blood brain barrier, thus magnesium threonate is the only form of magnesium that can pass through to the brain. As a BDNF promoter, it improves neuroplasticity and also has neuroprotective...
