The Active Ingredient Is: Magnesium (Citrate Form)

Magnesium is an essential mineral that supports energy production, muscle function, and normal nerve activity. Magnesium citrate is a highly absorbable form, enabling magnesium to reach tissues efficiently. Its solubility supports bioavailability, which is why it is commonly used in supplements.

What Does Magnesium (Citrate Form) Do?

Magnesium plays a role in over 300 enzymatic processes, supporting muscle relaxation, normal nerve function, and energy metabolism. EFSA notes that magnesium supports normal muscle function and energy production, and the citrate form is highly bioavailable, aiding absorption. Dr. Walker of the University of Nebraska found that magnesium citrate is highly bioavailable.
