Introduction

Magnesium is an essential mineral involved in more than 300 biochemical reactions in the body. It supports muscle relaxation, nerve signaling, energy production, blood sugar regulation, and heart rhythm stability.

What Is Magnesium?

Magnesium is a major dietary mineral required for maintaining normal muscle, nerve, and metabolic function.

• Type: Essential mineral
• Main role: Enzyme activation and neuromuscular function
• Storage: Bones, muscles, and soft tissues

How Magnesium Works in the Body

Magnesium acts as a natural calcium antagonist, helping muscles relax and nerves transmit signals efficiently.

• Regulates muscle contraction and relaxation
• Supports nerve impulse transmission
• Plays a role in ATP (energy) production
• Helps maintain normal heart rhythm

Sources of Magnesium

• Green leafy vegetables (spinach)
• Nuts and seeds (pumpkin seeds, almonds)
