Why You Might Be Running on Empty

You sleep eight hours and still wake up exhausted. You drag through the afternoon. You blame stress, work, or just getting older. But the real culprit might be sitting in your blood work, overlooked.

Iron Deficiency Is Incredibly Common

According to the WHO, iron deficiency affects over 2 billion people globally. Women of reproductive age, vegetarians, endurance athletes, and frequent blood donors are at highest risk.

Symptoms Go Beyond Fatigue

Low iron can cause pale skin, brittle nails, cold hands and feet, restless legs, shortness of breath during exercise, and difficulty concentrating. Many people live with these symptoms for years without checking their iron levels.

Ferritin: The Number That Matters Most

Your doctor might say your iron is "normal" based on serum iron alone. But ferritin, your body's iron storage marker, tells the real story. Optimal ferritin levels are much higher than the minimum reference range suggests.
