Iron Deficiency Is More Common Than You Think, Especially in Women

Fatigue, brain fog, cold hands, hair loss, brittle nails — these vague symptoms are often dismissed as stress, but they're classic signs of iron deficiency, the world's most common nutritional deficiency. Women of reproductive age, vegetarians, and frequent blood donors are especially at risk. A simple blood test (ferritin level) can confirm it. Don't self-supplement with high-dose iron — too much is also harmful. Get tested first, then work with your doctor on the right dose and form. The difference in how you feel can be dramatic.
