• Mitochondrial Energy Production: Magnesium is required for the stability and activation of ATP (as Mg-ATP), and citrate is a central intermediate in the citric acid cycle that generates cellular energy.*[1,2]
• Muscle and Nerve Function: Magnesium regulates muscle contraction and nerve signaling, including in the heart and vasculature.* Deficiency may impair these functions, especially under physical or metabolic stress.*[3]
• Bone Health: Magnesium is essential for calcium absorption, vitamin D activation, and bone matrix formation.* Higher magnesium intake is linked to greater bone mineral density in observational and interventional studies.*[4]
• Stress Regulation and Mood: Magnesium contributes to neurotransmitter metabolism and modulates catecholamines via COMT, as well as adrenal cortisol output.* Magnesium supports mood, relaxation, and sleep quality under stress.*[5,6,7]
• Population Need: Magnesium intake is suboptimal in most U.S. adults, especially women, due to depleted soil levels and food processing losses.* Magnesium citrate is more bioavailable and better tolerated than magnesium oxide or sulfate forms.*[2]
