This is the only magnesium supplement proven to actually reach your brain. While other magnesium forms struggle to cross the blood-brain barrier, L-Threonate was engineered specifically for cognitive support. Research shows it may enhance memory, learning, and overall brain function.
Why It Works
CROSSES THE BLOOD-BRAIN BARRIER: Unlike magnesium oxide or citrate, L-Threonate penetrates brain tissue where cognitive benefits actually happen.
SUPPORTS SYNAPTIC FUNCTION: Helps maintain the neural connections essential for memory formation and recall.
PROTECTS BRAIN CELLS: Magnesium's antioxidant properties help shield neurons from oxidative damage.
What's Inside
Each capsule delivers 48mg elemental magnesium from 667mg patented Magtein magnesium L-threonate. Clean vegetarian capsules with minimal fillers. Made in Canada with rigorous quality testing.
Why we carry it: Natural Factors uses the original patented Magtein compound — the same form used in the breakthrough MIT research on brain magnesium.
Recommended adult dose: 1 capsule 3 times daily or as directed by a health care practitioner. Use for a minimum of 6 weeks to see beneficial effects on cognitive function. Consult a health care practitioner for use beyond 3 months. Consult a health care practitioner if symptoms persist or worsen. Consult a health care practitioner prior to use if you are pregnant or breastfeeding. Keep out of the reach of children.
