Recommended Iron vs Age
Formule
## Iron Intake Recommendations Iron is essential for oxygen transport in the blood. Requirements vary by age and dietary pattern. ### RDA for Males | Age | RDA | |---|---| | 1-3 years | 7 mg | | 4-8 years | 10 mg | | 9-13 years | 8 mg | | 14-18 years | 11 mg | | 19+ years | 8 mg | Vegetarians need 1.8x more iron because plant-based (non-heme) iron is less readily absorbed.

What are iron-rich foods?
Red meat, poultry, fish, beans, lentils, spinach, fortified cereals, and tofu are all good sources of iron.
What are signs of iron deficiency?
Fatigue, weakness, pale skin, cold hands and feet, brittle nails, and frequent infections are common symptoms.
