Does Magnesium Actually Help Brain Health? What We Know So Far

What is magnesium’s role in brain health?

Magnesium is an essential mineral that supports cognitive function, including memory formation, learning ability, and stress regulation.

Key functions

  • Supports synaptic plasticity for learning and memory

  • Regulates neurotransmitters such as GABA and glutamate

  • Helps protect neurons from oxidative stress

Who this is for

  • Adults experiencing brain fog or reduced focus

  • Individuals with high stress or poor sleep quality

 

Which form of magnesium is best for cognitive function?

Magnesium L-threonate (Magtein®) is the most research-supported form for brain health due to its ability to increase magnesium levels in the brain.

Why Magtein® stands out

  • Crosses the blood-brain barrier

  • Increases brain magnesium concentration

  • Supports memory, learning, and attention
