The Active Ingredient Is: Magnesium (Citrate Form)
Magnesium citrate is a naturally occurring mineral form known for its high bioavailability and role in supporting normal muscular and nervous system function.
This form provides magnesium ions in a citrate matrix, which is commonly recognised for efficient absorption and utilisation in the body.
What Does Magnesium (Citrate Form) Do?
Magnesium contributes to normal muscle function, nerve transmission and energy production, functions that are central to daily activity and cardiovascular health. This aligns with EFSA guidance and related research on essential mineral roles for these physiological processes.
Dr. Zhang of University found that magnesium citrate can help maintain healthy serum magnesium levels and support muscle and cardiovascular function, reflecting its bioavailability and participation in key metabolic pathways.
