The Active Ingredient Is: Magnesium (Oxide Form)

Magnesium is a mineral essential for normal muscle and nerve function and energy metabolism.

This form is magnesium oxide, a common inorganic source used in supplements that liberates magnesium ions to participate in cellular processes supporting muscle function, nerve signalling and energy production.

What Does Magnesium Do?

Magnesium contributes to normal muscle and nerve function and to energy metabolism, aligning with EFSA guidance on essential minerals.

Dr. Rosanoff of the University of California found that magnesium contributes to bone density and maintenance of normal cardiac rhythm.
