Magtein is a patented, next-generation organic form of magnesium in the form of magnesium-L-threonate that supports proper nervous system and mental function
Magtein is a premium, patented form of magnesium in the form of magnesium-L-threonate (magnesium threonate). This unique combination of an essential mineral with L-threonic acid creates a highly bioavailable organic form of magnesium. This is particularly popular as a support for the psyche and the nervous system, which controls the function of all organs in the body, due to its unique structure. Magtein was discovered and patented by scientists at the prestigious Massachusetts Institute of Technology (MIT). Since then, it has been considered one of the most advanced and innovative forms of this mineral.
Magnesium also contributes to electrolyte balance and optimal energy metabolism. It also participates in the proper function of muscles and helps reduce fatigue and exhaustion. Moreover, it also supports the maintenance of healthy bones and teeth. Thanks to these properties, all athletes and people with an active lifestyle will appreciate it in their daily routine.
Magtein is ideally taken in the evening, when the body and mind are preparing for rest. It is suitable for anyone who wants to effectively replenish essential magnesium during the challenging days, even during high mental and physical stress. Thanks to its composition, it represents a modern way of magnesium supplementation, which will appeal even to more demanding users looking for more than just regular magnesium.
A daily dose (3 capsules) contains 144 mg of magnesium, which corresponds to 38.4% of the reference intake. It is gluten-, lactose- and GMO-free and is also suitable for vegetarians and vegans. Try a form of magnesium that is also recommended by neuroscientist and professor in the Department of Neurobiology at Stanford University, Andrew Huberman.
Other benefits of magtein include its effects on brain function. In fact, it is being intensively studied for its ability to pass the brain barrier. Magnesium is known to support optimal mental functions, among which are the ability to concentrate, remember, learn and think. This is why it is a popular supplement for increased mental workload. It is also worth taking it before bed as part of a daily evening routine. This makes it a great magnesium for the brain, memory, and sleep. Try Magtein and discover the power of next-generation, highly absorbable magnesium to give you advanced care for both mind and body.
