Research on Magtein® Magnesium L-Threonate

• Magtein® Magnesium L-Threonate has been studied for its ability to support brain magnesium levels, cognitive performance, and sleep quality. For a deeper breakdown of the studies, doses, durations, and outcomes, visit our Magtein® Magnesium L-Threonate research page.
• In a 2016 randomized, double-blind, placebo-controlled trial by Liu et al., researchers studied MMFS-01, a magnesium L-threonate formula, in adults aged 50–70 with cognitive impairment and observed improvements in measures of cognitive ability over 12 weeks.
• A randomized, double-blind, placebo-controlled trial by Lopresti and Smith studied 2 g per day of Magtein® in 100 adults aged 18–45 with self-reported dissatisfied sleep over 6 weeks, evaluating cognitive performance, cognitive age, sleep quality, and related physiological markers.
• The original 2010 Neuron study by Slutsky et al. helped establish the mechanism behind magnesium L-threonate, showing in animal research that increasing brain magnesium was associated with improvements in learning, working memory, short-term memory, long-term memory, and synaptic density.
