Magnesium Deficiency: The Overlooked Mineral

Magnesium is involved in over 300 enzymatic reactions in your body, yet deficiency is remarkably common and often missed by standard testing.

Why Magnesium Matters

Magnesium is essential for: - Energy production - Muscle and nerve function - Blood sugar regulation - Blood pressure control - Sleep quality - Stress response - Bone health

Symptoms of Deficiency

• Muscle cramps and twitches
• Fatigue
• Anxiety and irritability
• Insomnia
• Headaches
• Heart palpitations
• PMS symptoms

Why It's Underdiagnosed

Standard serum magnesium tests only measure blood levels, which represent just 1% of your body's magnesium. Your body tightly regulates blood magnesium, pulling from bones and tissues when needed.

Better Testing Options

Serum Magnesium Standard test, but insensitive. Only shows severe deficiency.

RBC Magnesium Measures magnesium inside red blood cells. More accurate reflection of body stores. Optimal is 5.0-6.5 mg/dL.

Consider Your Symptoms If you have symptoms of deficiency and risk factors, supplementation may be warranted even with "normal" levels.

Risk Factors

• Stress (depletes magnesium)
• High sugar intake
• Digestive disorders
• Diabetes
• Alcohol use
• Certain medications (PPIs, diuretics)
