What does iron do in the human body? Special iron requirements
The main functions of the iron in the body are:
- Iron deficiency anemia: The ingestion of iron through foods or supplements helps to prevent and to fight the anemia produced by the lack of this mineral.
- Losses or very high iron consumption: A higher intake of iron may be necessary in certain cases such as:
- Pregnancy or breastfeeding. During these periods women need more iron than usual because the baby consumes large quantities of this mineral.
- Menstruation: During menstruation, especially young women, a great amount of blood is lost, so they need a higher ingestion this mineral.
- Babies and children or girls in the growth phase: This period implies a major consumption of iron.
- People who practice intensive sports: These people use a lot of iron and could need an superior ingestion the same.
- People who have suffered blood loss as the result of surgery, accident or injury or both external and internal lesions (ulcers, tumors, bleeding, nose bleeding, etc.).
- Weight-loss diet: Very strict diets can entail low iron levels in the body.
- Very strict vegetarian Diets: Given the lower absorption of heme iron from vegetables, vegetarian diets could be responsible for most studied body iron deficits.
Daily iron requirements
The recommended daily allowance (RDA) for iron is 10 mg for men over 19 years and 15 mg for women over 11. Iron is best absorbed with vitamin C, so you should eat foods high in vitamin if you opt for a diet containing high levels of iron or when we need to take supplements of this mineral.

Toxicity of iron
Iron supplements should only be taken when the doctor considers it necessary. Higher doses than recommended are toxic. It is necessary to take iron supplements away from the reach of children, for whom its ingestion is especially dangerous (3 g of iron can kill a child under 2 years)
People taking other supplements should check that they do not contain iron, therefore, they may not need it, Self-medication for a supposed lack of iron could mask the real reasons why the body needs greater amounts of this mineral. Only the physician must diagnose the causes of this anomaly and prescribe the appropriate treatment.
Excess of iron-rich foods, especially meats abuse, may be responsible for high blood iron level in Western society, one of the reasons that causes problems in heart and liver.
