What Does Magnesium L-Threonate Do?

Unlike standard magnesium supplements, Magnesium L-Threonate (Magtein®) is uniquely able to penetrate the blood-brain barrier, directly increasing magnesium concentrations in the brain. This supports synaptic density, neurotransmitter function, and long-term cognitive health — benefits not seen with other forms of magnesium.
