Store the product in its original packaging in a cool, dry place and keep it away from direct sunlight.

Magtein® is the patented and clinically studied form of Magnesium L-Threonate developed through research originating at MIT. It is backed by multiple clinical and preclinical studies evaluating brain health, cognition, and sleep support.

Magnesium L-Threonate is a unique and highly bioavailable form of magnesium specifically researched for brain and nervous system support. Unlike traditional forms of magnesium, Magnesium L-Threonate has been shown in multiple studies to effectively increase magnesium levels in the brain. This is possible thanks to its patented Magtein® technology, developed from MIT-origin research, which combines magnesium with L-threonic acid — a natural Vitamin C metabolite naturally found in the brain.

Yes. Magnesium L-Threonate is one of the only forms of magnesium studied for its ability to effectively cross the blood-brain barrier and raise brain magnesium levels. More than 7 clinical and preclinical studies, including 2 published human randomized controlled trials (RCTs), support its role in brain health, memory, learning, and cognitive performance.

Higher brain magnesium levels are associated with improved synaptic plasticity — the brain’s ability to learn, adapt, and consolidate memories. Magnesium also plays an essential role in activating GABA receptors and supporting melatonin synthesis, both central to relaxation and sleep quality. Our formula also includes pantothenic acid (Vitamin B5), which contributes to the normal synthesis and metabolism of neurotransmitters involved in cognition, mood, and sleep.
