Magtein® (magnesium L-threonate) is a patented form of magnesium that’s made by combining magnesium and a vitamin C compound called threonic acid. Magnesium is an essential mineral that’s involved in over 300 metabolic reactions and plays an important role in everything from heart health to exercise performance to brain function.

Magtein is a relatively new type of magnesium that has been included in various supplements due to its ability to reduce anxiety, improve sleep quality, lift mood, and improve focus and concentration.

Magtein is the only magnesium compound that has been shown to effectively raise the brain's magnesium levels, which leads to enhanced learning abilities, improved working memory, and better short and long-term memory in both young and aged animals.*
