Iron Deficiency in Women: Signs and Solutions

Women of reproductive age lose iron monthly through menstruation, creating a higher baseline requirement. The NIH Office of Dietary Supplements sets the RDA at 18 mg per day for premenopausal women compared to 8 mg for men.

Pregnancy further increases iron demands to 27 mg daily to support expanded blood volume and fetal development. The NIH notes that these elevated needs make supplementation necessary for most pregnant women.

The NIH identifies persistent fatigue, weakness, pale skin, cold hands and feet, and brittle nails as classic indicators of iron deficiency. These symptoms develop gradually and are often normalized before being investigated.

Restless legs, frequent headaches, and unusual cravings for non-food items like ice are less well-known symptoms that also point to inadequate iron stores. A complete blood count and ferritin test confirm the diagnosis.

Heme iron from animal sources like red meat, poultry, and shellfish is absorbed 2-3 times more efficiently than non-heme iron from plant foods. The NIH recommends including both types in the diet for optimal iron status.

Consuming vitamin C alongside iron-rich foods dramatically improves absorption, especially for plant-based iron. A glass of orange juice with an iron-fortified cereal or tomatoes in a bean dish can double or triple the amount of iron your body absorbs.
