How to use


Magtein Magnesium L Threonate, developed by a team of MIT scientists, is a patented form of magnesium. When developing Magtein Magnesium L Threonate, the goal was to have a magnesium amino acid chelate that reached the brain efficiently. Developers decided that the amino acid L-Threonate, which is a metabolite of vitamin C, would be best for this function. L-Threonate is a unique amino acid which appears to enhance mitochondrial function, synaptic density, and neuroplasticity on its own. It partially elevates neuronal intracellular magnesium levels which act as a second messenger. The chelation of Magtein Magnesium L Threonate allows L-Threonate to enhance neuronal intracellular magnesium levels, while the magnesium elevates its levels throughout the body and the brain.


  • Mag L-Threonate appears to demonstrate a chemical attraction to the brain. In fact, there is about 5 more times L-Threonate in the brain than the rest of the body. This is a significant finding since it indicates Magnesium L-Threonate may be especially effective at elevating magnesium levels in the brain. Research has indicated that magnesium L-threonate is one of the only forms of magnesium that reaches and enters the brain efficiently at significant levels (1).
  • Researchers concluded that Magtein lead to an increase in brain magnesium levels, with an increase in both short-term synaptic facilitation and long-term potentiation, leading to improvements in learning and memory functions (2).
  • Elevation of brain magnesium exerts substantial synaptoprotective effects in a mouse model of Alzheimer’s disease, and hence it might have therapeutic potential for treating Alzheimer’s disease (3).
  • One randomized, double-blind, placebo-controlled study examined the effects of Magtein (MMFS-01) on cognitive decline in older adults. A total of 44 participants (age 50-70) with mild cognitive impairment were given placebo or MMFS-01 (25 mg per kg body weight) daily for 12 weeks. Compared to placebo, the MMFS group experienced improvement of cognitive ability and and cognitive fluctuation – large fluctuations in mental capacity over time (such as having “bad days”). nearly restored their cognitive function to the level of healthy adults (4).


  • Animal studies demonstrate that Magtein helps reduce fear-related memories, and prevents fear memories from becoming over-generalized—actions that contribute directly to reductions in anxiety (5). While fear plays an important role in keeping us safe from real threats, persistent fearful memories from a specific traumatic occurrence can cause us to become anxious and even paralyzed into inactivity.
  • A study conducted at Tsinghua University found that participants reported significant reductions in anxiety, experienced less stress when performing cognitive tasks, and had greater mental clarity. Furthermore, a different paper published in the journal Pain Physician found that Magtein prevents and reverses memory deficits associated with chronic neuropathic pain (6).

Magtein was evaluated in a series of cognitive tests within four major domains of the brain: executive function, working memory, attention and episodic memory. The most striking finding of this Magtein Inventor’s Formula human trial was an improvement in executive function. This improvement is equivalent to a nine-year reduction in "brain age" with just 12 weeks of supplementation.


I am very picky with my magnesium supplements. However this type of magnesium truly does impress me. I'm a huge fan.
