Excess iron intake can be dangerous: Four signs to watch for

Excessive iron consumption poses significant health risks, with experts warning that very high doses can be fatal, particularly for children. Iron is an essential mineral for producing hemoglobin, the protein in red blood cells that transports oxygen throughout the body, and plays a role in energy, immunity, and metabolism.

Very high doses of iron can be fatal, especially if taken by children.

Maintaining the right balance of iron is critical, as both deficiency and excess can lead to health problems. While iron supplements can address low levels, leading to anemia with symptoms like fatigue and shortness of breath, overconsumption carries severe consequences. The UK's National Health Service (NHS) notes that excess iron can cause constipation, nausea, vomiting, and stomach pain.

Health authorities emphasize that children are especially vulnerable, and iron supplements should always be kept out of their reach. For adults, a daily intake exceeding 20 milligrams is considered high. The UK's Department of Health and Social Care advises that most individuals can obtain sufficient iron from a varied and balanced diet.

Recommended dietary sources of iron include liver (though pregnant women should avoid it), red meat (consumption of which should be limited due to potential cancer risks), beans, nuts, dried fruits, fortified cereals, and soy flour. Balancing these sources with caution regarding supplements is key to avoiding iron toxicity.
