What Is Magnesium and Why Is It Important?

Magnesium is a vital mineral responsible for supporting:

  • Healthy muscle and nerve function

  • Energy production (ATP)

  • Sleep quality and stress regulation

  • Blood pressure balance

  • Blood sugar control

  • Protein synthesis

  • Bone strength

Because soil quality has declined and modern diets lack magnesium-rich foods, deficiencies are increasingly common — making supplementation a popular solution.

🧠 Signs You May Be Low in Magnesium

You may benefit from magnesium supplements if you experience:

  • Trouble sleeping

  • Muscle cramps or twitching

  • Stress, anxiety, or irritability

  • Fatigue or low energy

  • Headaches or migraines

  • Irregular heartbeat

  • PMS symptoms

  • Constipation

If multiple symptoms apply, your magnesium levels may be lower than optimal.
