The Active Ingredient Is: Magnesium L-Threonate (Magtein)

Magnesium L-threonate is a magnesium salt created to boost brain magnesium stores and support cognitive function.

This form, marketed as Magtein, is known for its capacity to cross the blood-brain barrier and deliver magnesium to neural tissue, helping normal brain function.

What Does Magnesium L-Threonate Do?

Magnesium helps support normal synaptic function and neurotransmitter activity, which are key for learning and memory processes.

The mechanism involves delivering magnesium to brain tissue to support synaptic density and communication within neural networks, with research suggesting potential improvements in memory and cognition in older adults.
