Yes, iron overdose can be dangerous. Research shows that excessive iron intake can lead to:
- Severe stomach pain and nausea
- Organ damage
- Increased risk of heart disease
- Iron overload (hemochromatosis)
The recommended daily allowance varies by age and gender, but generally shouldn’t exceed 45mg for adults without medical supervision. Keep supplements away from children as iron overdose is a leading cause of fatal poisoning in young children. Always get your iron levels tested before starting supplementation, and never exceed the recommended dose without medical advice. Some people, particularly those with hereditary hemochromatosis, should avoid iron supplements entirely.
