Life Extension Neuro-Mag® Magnesium L-Threonate | Memory & Cognitive Function, 90 Vegetarian Capsules
Most magnesium supplements never reach your brain. Magnesium L-Threonate is different — it's the only form of magnesium clinically shown to effectively cross the blood-brain barrier and raise magnesium levels in the brain. Developed by researchers at MIT, this patented Magtein® form has been studied specifically for its effects on memory, cognitive function, and mental clarity. Life Extension Neuro-Mag® is the Amazon Overall Pick with over 24,000 five-star reviews — and for good reason.
What the Research Shows
A landmark clinical study published in the Journal of Alzheimer's Disease found that Magnesium L-Threonate (Magtein®) significantly improved overall cognitive ability, short-term memory, and executive function in older adults. Participants showed improvements equivalent to being 9 years younger in cognitive age after just 12 weeks. Unlike standard magnesium supplements, Neuro-Mag® is absorbed directly by brain cells — where it's needed most.
