What is Iron?
Iron is an essential mineral that's a key component of hemoglobin, the protein in red blood cells that carries oxygen from your lungs to every cell in your body. It's also part of myoglobin, which provides oxygen to muscles.
Iron Deficiency Anemia
Iron deficiency is the most common nutritional deficiency worldwide. It leads to anemia—a condition where your blood can't carry enough oxygen, causing fatigue, weakness, pale skin, and impaired cognitive function.
Heme vs Non-Heme Iron
Heme iron (from animal sources) is absorbed 2-3 times more efficiently than non-heme iron (from plants). Vitamin C significantly enhances non-heme iron absorption, while calcium, tannins, and phytates inhibit it.
Who Needs More?
Women of childbearing age, pregnant women, vegetarians/vegans, frequent blood donors, and endurance athletes often have higher iron needs. However, too much iron can be harmful, especially for those with hemochromatosis.
Testing and Supplementation
Ferritin (stored iron) is a better indicator of iron status than hemoglobin. Supplement only if deficient—iron overload is dangerous. Take iron supplements away from calcium and coffee for best absorption.
