Magnesium threonate can readily cross the blood brain barrier and serve as a neurological cofactor for supporting mental focus, mood balance, stress responses and sleep balance, whilst also supporting magnesium levels in the entire body. According to animal research, Magtein® has been shown to support healthy magnesium levels in the brain, in contrast to other magnesium compounds. Of six magnesium compounds studied, researchers found that magnesium-L-threonate was the superior compound able to support mental health and focus. A breakthrough in brain health Unique delivery of magnesium into the brain. Helps support healthy memory, learning and concentration.

Magnesium is an essential mineral and important cofactor that is involved in over 300 enzymatic processes. It helps to support cardiovascular health, normal muscle and nerve function, strong bones, blood sugar balance, energy metabolism, and a healthy immune system. Magnesium is essential for brain connections that facilitate and support mental health and focus as well as overall brain health. Magnesium is a cofactor for numerous enzymes involved in nerve cell functions and synapse integrity. Synapses are the points where nerve cells make close contact with each other via their cell membranes to exchange information. The movements of ions such as magnesium across the nerve cell membranes can change as we age. Ingredients Magnesium (from 2085 mg Magtein® Magnesium L-Threonate) 150 mg.
