Magtein Magnesium L-Threonate

NOW Magtein™ is a patented form of Magnesium that readily crosses the blood-brain barrier for utilization in the brain.

Magnesium is an essential mineral best known for its role in bone and nervous system function and research has demonstrated that it is also critical for normal brain health and normal cognitive function by maintaining the density and stability of neuronal synapses.

However, most forms of Magnesium are not easily absorbed into the nervous system. Laboratory studies indicate that Magtein™ supports brain health and may facilitate learning and memory, as well as a relaxed mood.
