Magnesium L-Threonate, often sold under the brand name Magtein, is a synthetic form of magnesium where the mineral is chelated to L-threonate, a sugar acid derived from ascorbic acid (vitamin C). This specific chelation is noteworthy because it has been shown in preclinical studies to enhance magnesium's ability to cross the blood-brain barrier. This makes Magnesium L-Threonate particularly interesting for its potential effects on brain health and cognitive function, distinguishing it from other magnesium supplements that may not as readily increase magnesium levels within the brain itself. Most magnesium supplements primarily aim to correct systemic magnesium deficiencies, which can impact various bodily functions. Magnesium L-Threonate, while also contributing to overall magnesium status, is specifically studied for its neuroactive properties. It is available as an oral supplement, typically in capsule or powder form.
