    About this item

    Product details

    Highly Bioavailable Form: Magnesium L-threonate is the salt formed from mixing magnesium and threonic acid, a water-soluble substance derived from the metabolic breakdown of vitamin C. Easily absorbed, our magnesium L threonate capsules are used for their overall brain health benefits and may help support memory, focus, relaxation, mood, and cognition.

    Made With Magtein: Magtein is a patented compound called threonic acid developed by a group of MIT researchers.

    I didn’t know how much I need this!

    I’ve been taking the Magnesium L-Threonate for almost 2 months before bed. It helps me unwind and sleep more soundly and I awaken more alert and energetic. I only wish it was cheaper.
