Magtein (magnesium threonate) 90 capsules – NOW
Contains magnesium L-threonate, a highly bioavailable form of magnesium that is particularly known for its ability to cross the blood-brain barrier. Unlike other forms of magnesium, magnesium threonate has the potential to influence magnesium levels in the brain, making it particularly interesting for those who want to support cognitive health, memory function, and mental clarity.
– Can cross the blood-brain barrier for optimal absorption, even in the brain
– Is believed to support cognitive function, reduce fatigue, and contribute to the normal functioning of the nervous system
Magtein (magnesium L-threonate) has been shown to increase synaptic density and neuroplasticity, particularly in the parts of the brain involved in memory, learning, and emotions. This formulation is a combination of magnesium and L-threonic acid—a metabolite of vitamin C.
The usual dosage of Magtein® is 1,000–2,000 mg per day, divided into 2–3 doses. Since magnesium L-threonate contains relatively little elemental magnesium (~7–8 %), a higher total dose is required than with, for example, magnesium citrate to achieve the desired effect.
Magtein® is now considered a nootropic substance, with users reporting increased mental clarity, focus, and calmness after three to six weeks of use. It is said to promote clear thinking. You can read more here: https://magtein.com/
