What is Magnesium L-Threonate?

Magnesium L-threonate (MgT) is a form of magnesium specifically developed by MIT researchers to cross the blood-brain barrier more effectively than other magnesium forms. It has been studied for its potential to increase brain magnesium levels and support synaptic plasticity and memory.

What dosage of Magnesium L-Threonate has been used in studies?

Clinical trials have used approximately 1,500 mg to 2,000 mg of magnesium L-threonate daily, providing roughly 144 mg of elemental magnesium. This is typically taken in divided doses. Consult your healthcare provider for appropriate dosing based on your magnesium status.

What are the potential side effects of Magnesium L-Threonate?

Side effects are generally mild and may include headache, drowsiness, and digestive discomfort. Excessive magnesium from any source may cause diarrhea. People with kidney disease should be cautious with magnesium supplements. Consult your healthcare provider before use.

About

Magnesium L-Threonate is the only magnesium form demonstrated to effectively cross the blood-brain barrier. It increases synaptic density in hippocampal and prefrontal regions, enhancing both short-term and long-term memory. A 30-day RCT showed significant improvements across all five subcategories of clinical memory testing.

How It Works

The only magnesium form demonstrated to effectively cross the blood-brain barrier; increases synaptic density in hippocampal and prefrontal regions; enhances both short-term and long-term memory via NMDA receptor modulation and synaptic plasticity.
