Magtein is a patented form of magnesium, from Magnesium L-Threonate, that readily crosses the blood-brain barrier for utilization in the brain.

Most magnesium compounds have low brain bioavailability. Magtein (MgT) is the only magnesium compound that has been shown to effectively raise the brain's magnesium levels in both young and aged animals.

Scientists have recently evaluated the ability of both bioavailable organic and inorganic magnesium forms to raise brain magnesium levels. Magnesium concentration in the cerebrospinal fluid was evaluated following treatment with different magnesium compounds, including Magtein. After 24 days, Magtein was the only magnesium compound shown to raise the cerebrospinal fluid magnesium concentration with statistical significance.

Magtein™ is a Magceutics trademark.
