Magnesium is an essential mineral that plays a vital role in hundreds of bodily functions—yet many people don’t get enough of it! From supporting muscle function and energy production to maintaining bone health and a balanced nervous system, magnesium is a true multitasker. One unique form, Magnesium L‑Threonate, stands out for its ability to cross the blood‑brain barrier.

Magtein^® Magnesium L‑Threonate Supreme is formulated with the clinically researched Magtein^®—a highly bioavailable form of magnesium that is bound to threonic acid, a metabolite of vitamin C. Threonic acid has good gut bioavailability and can cross the blood-brain barrier as it is naturally occurring in the cerebrospinal fluid. As a key mineral, magnesium contributes to overall health by supporting bone development and normal muscle function, including heart function. Magtein^® Magnesium L‑Threonate Supreme provides essential nutrients for optimal wellness.
