Metagenics Magtein® Magnesium L-Threonate, 120 Capsules

Metagenics Magtein® Magnesium L-Threonate is a cognitive health supplement designed to support memory, focus, and mental clarity. It features Magtein®, a patented form of magnesium L-threonate developed for enhanced bioavailability and brain-targeted delivery, with each serving providing magnesium in a formulation backed by clinical research.

This product is notable for its specific focus on brain health, distinguishing it from other magnesium forms like glycinate that are often used for muscle relaxation or sleep. The manufacturer cites a randomized, double-blind, placebo-controlled trial where Magtein® supplementation was associated with a statistically significant improvement in modeled cognitive age, corresponding to an estimated 7.5-year difference versus placebo in healthy adults. Metagenics produces it in GMP and NSF-certified facilities, with third-party testing for purity and potency, and it is Non-GMO, Vegetarian, and Gluten-Free. Available in a 120-capsule container, the recommended dosage is three capsules daily, providing 2 g of Magtein® (magnesium L-threonate) and 147 mg of elemental magnesium.
