Cymbiotika’s Liposomal Magnesium L-Threonate was developed by a team of scientists at MIT which has been shown to increase brain magnesium levels much higher than any other form of magnesium. Magnesium is an essential mineral that is required for 80% of the body’s metabolic functions. In the United States, approximately 65% of all adults are magnesium deficient. Magnesium deficiency contributes to many chronic conditions including heart disease and loss of cognitive function.
