Formulation
Formula re: Contains
How it works: Magnesium (Mg) is known to play a major role in cellular metabolism and is critical for normal nervous system function. Recent research has demonstrated that Mg also helps to regulate neuronal synapse density and that availability of Mg in the brain is necessary for the stability and adaptability of these neuronal connections. Magtein (Magnesium L-Threonate) is a patented form of Mg that crosses the blood-brain barrier and is readily utilized in the brain. Preclinical studies indicate that Magtein may support healthy cognitive function, learning, and memory, and may promote a relaxed mood.
