Comparison
Magnesium L-Threonate vs EGCG (Green Tea)
Magnesium L-Threonate
MIT-developed magnesium that crosses the blood-brain barrier. Shown to enhance synaptic density and reduce 'brain age'.
EGCG (Green Tea)
Most abundant catechin in green tea. Antioxidant, mild ACh esterase inhibitor, and metabolic enhancer.

The comparison in plain English
Auto-generated from dataMagnesium L-Threonate and EGCG (Green Tea) are both in the neuroprotective category respectively. Magnesium L-Threonate MIT-developed magnesium that crosses the blood-brain barrier. EGCG (Green Tea) Most abundant catechin in green tea.
Bottom line
Magnesium L-Threonate (evidence B, safety 5/5) has a stronger evidence base than EGCG (Green Tea) (evidence A, safety 4/5). Magnesium L-Threonate has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose Magnesium L-Threonate if
Magnesium L-Threonate is the better fit when your goal aligns with its mechanism (L-threonate is a sugar-acid carrier that uniquely enables magnesium to cross the blood-brain barrier in meaningful quantities, most oral magnesium forms (oxide, citrate, glycinate) raise serum magnesium but not central magnesium) and the dose range (1000–2000mg) suits your protocol. Half-life is 6h.
Choose EGCG (Green Tea) if
EGCG (Green Tea) is the better fit when your goal aligns with its mechanism (Powerful antioxidant, one of the most reactive natural radical scavengers known) and the dose range (200–500mg) suits your protocol. Half-life is –h.
