Swanson Magnesium L-Threonate featuring Magtein® promotes healthy neuronal activity for the support of healthy cognitive function. Traditional solutions for cognitive support involve stimulating the neurons to promote peak brain function. But over time, this can lead to burnout and have the opposite effect. Magnesium L-Threonate works differently. Its patented form of magnesium nourishes the brain where it works to enhance synaptic density and neuroplasticity. Essentially, it helps to maintain or even increase the connections between nerve cells in the brain. This can mean quicker, clearer thinking and support for cognitive functions such as learning and memory.
Recent studies of Magtein point to exciting findings. Researchers have found that consistent supplementation may improve cognition, cognitive age, reaction time and even memory. It may also positively impact heart rate, pointing to benefits for stress management.(1) Along the same lines, it may improve deep sleep quality,(2) which encourages a positive mood, alertness and healthy energy levels.
Preliminary research suggests great potential for this magnesium—the only form known to readily cross the blood-brain barrier and function within the brain. Studies have indicated an increase in levels of magnesium in the brain, where it is required for the production of serotonin(2) and ATP.(3) Serotonin in the brain impacts mood and nervous system function, while ATP is the source of cellular energy for high-demand organs such as the brain.
