MineralsKey Benefits
How It Works
Magnesium L-threonate (Magtein) was developed at MIT specifically to increase brain magnesium levels. L-threonate is a metabolite of vitamin C that efficiently transports magnesium across the blood-brain barrier, increasing cerebrospinal fluid magnesium concentrations where other forms cannot.

Recommended Dosage
1,000-2,000 mg (providing ~144 mg elemental Mg) daily
Best Time to Take
Split dose: morning and evening, or all evening

Patented Magtein form specifically
Side Effects
Generally well-tolerated. Some report initial headaches or drowsiness. Contains less elemental magnesium per capsule.
Drug Interactions
Similar to other magnesium forms. May enhance sedative effects of sleep medications.
What Does The Research Say?
The landmark MIT study showed it reversed brain aging by 9-14 years in cognitive tests. Subsequent human trials demonstrated improvements in executive function and working memory, particularly in older adults.
