The brain and body require magnesium for various crucial functions, including enzyme reactions, nerve health, DNA and protein synthesis, and muscle function.† Early research shows that Magnesium L-Threonate supports memory and learning and healthy brain synapse density and overall brain function.† Magnesium L-Threonate has also been reported to help with enhancing the quality of sleep, given the calming effect often seen through magnesium supplementation.†


Magnesium L-Threonate can penetrate the blood-brain barrier at higher levels than other forms of magnesium and is thus the most bioavailable magnesium for the brain. Magnesium is a mineral that is crucial for a wide variety of functions in the human body, including helping with muscle contraction, regulating blood pressure, and helping with the synthesis of DNA and proteins. Magnesium is also essential for optimal nerve transmission and neuromuscular coordination in the nervous system.
