Sports Research Magtein Magnesium L-Threonate is a premium brain health supplement containing 2000mg of highly bioavailable magnesium L-threonate per serving. Magtein is a patented compound developed by MIT researchers specifically designed to cross the blood-brain barrier and increase magnesium levels in the brain, which is critical for improving cognitive function. This advanced formula uses threonic acid, a water-soluble substance derived from the metabolic breakdown of vitamin C, combined with magnesium to create the only form that effectively reaches the brain.

Each bottle contains 135 veggie capsules with a suggested use of 3 capsules daily, providing a 45-day supply. The formula may help support memory, focus, relaxation, mood, and cognition. Clinical studies have demonstrated improvements in all subcategories of memory tests, with effects positively associated with age, meaning older participants showed greater improvements. Research also shows benefits for sleep quality, particularly deep and REM sleep stages, along with improved mood, energy, alertness, and daily productivity.

The supplement is third-party tested, non-GMO verified, gluten-free, certified vegan, and cGMP compliant. Adults should take 3 veggie capsules daily with food, or as recommended by a qualified healthcare professional. For best results, take 1 veggie capsule in the morning and 2 at night before bed. Consult with a healthcare professional prior to using this product if you are pregnant, nursing, have a diagnosed medical condition, or are taking a prescription medication. Keep out of reach of children and pets. Store at room temperature in a dry place, and protect from excessive heat, freezing, humidity, and light.
