New research 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 and along with the most bioavailable inorganic magnesium (magnesium-chloride), and the most bioavailable organic magnesium (magnesium-gluconate). After 24 days, Magtein was the only magnesium compound shown to raise the cerebrospinal fluid magnesium concentration with statistical significance. This is the only product that combines the benefits of magnesium L-threonate with Inositol. Inositol supports healthy central nervous system function, and has been shown to support positive mood and a heathy stress response. This product has a natural sweetness that makes it easy to take for all ages! Suggested Dosage: Take ½ tsp either in water 2x daily or as directed by your healthcare practitioner. Each tsp contains 1000 mg Magtein with Inositol.
