Info: 90 Veg. Capsules

Magtein is a patented form of magnesium, from Magnesium L-Threonate, that readily crosses the blood-brain barrier for utilization in the brain, which may enhance learning abilities, short and long term memory, relaxation, as well as quality of sleep. Give yourself some peace of mind with Magtein.

Product Notes:

Magnesium is a powerhouse mineral that is involved in more than 300 reactions in the body; however, it is best known for its role in bone and nervous system function. Recent research has demonstrated this essential mineral is also critical for normal brain health and cognitive function by maintaining the density and stability of neuronal synapses. However, unlike Magtein, most forms of magnesium are not easily absorbed into the nervous system.

Magnesium is an essential co-factor for more than 300 enzymes involved in biosynthesis processes and energy metabolism. It plays an important role in many of the brain's functions. However, most magnesium compounds have low brain bioavailability. Magtein (MgT) is the only magnesium compound that has been shown to effectively raise the brain's magnesium levels in both young and aged animals. Scientists have recently evaluated the ability of both bioavailable organic and inorganic magnesium forms to raise brain magnesium levels. Magnesium concentration in the cerebrospinal fluid was evaluated following treatment with different magnesium compounds, including Magtein. After 24 days, Magtein was the only magnesium compound shown to raise the cerebrospinal fluid magnesium concentration with statistical significance.
