Neuro-Mag® Magnesium L-Threonate from Life Extension uses Magtein®, a patented form of magnesium L-threonate studied for its ability to be absorbed into the brain more readily than many other magnesium forms. Each three-capsule serving provides 144 mg of elemental magnesium from 2,000 mg of Magtein.
This vegetarian, non-GMO formula is intended to support memory, focus, and attention span, and tends to have less of a laxative effect than some other magnesium forms. Take three capsules daily, or as recommended by a healthcare practitioner.
