Moss Nutrition Magtein is a patented chelate of elemental magnesium and L-threonic acid, a vitamin C metabolite. Combined, they form magnesium-L-threonate (MgT), a unique magnesium compound capable of crossing the blood-brain barrier to effectively increase magnesium levels in the brain. 


Magnesium is a critical mineral for human health, involved in more than 300 metabolic reactions throughout the body. A required cofactor in many enzymatic processes, magnesium has a relaxing effect on the body and works in opposition to contractive calcium to enable muscles to relax. Magnesium is essential to cardiovascular health and plays key roles in energy production and insulin sensitivity. Magnesium is also an important structural mineral in bones, teeth, cell membranes, and chromosomes.


A gradual reduction in our ability to carry out everyday mental tasks and processes is common throughout adulthood. Cognitive function peaks around age 25 on average but may be reduced by up to 50% at age 80. Cognitive decline affects not only word recall, memory, and thinking speed but also sleep quality, mood, and stress levels. 


Magtein is easy on the digestive tract and is not likely to cause gastrointestinal issues that forms of magnesium, such as oxide and citrate, do.


Each three-capsule serving of Magtein® provides a clinically relevant 2 grams of magnesium-L-threonate.
