Clinical Trials, Supplement | featured news

More than a decade of research hinting that magnesium supplements might boost your brain power is finally being put to the test in a small clinical trial. The research, led by biopharmaceutical company Magceutics of Hayward, California, began testing the ability of its product Magtein to boost magnesium ion (Mg2+) levels in the brain earlier this month. The trial will track whether the ions can decrease anxiety and improve sleep quality, as well as following changes in the memory and cognitive ability of participants. But critics caution that the trial in just 50 people is too small to draw definitive conclusions.
