Iron is an essential mineral required by the body for the production of red blood cells, which bring oxygen to all parts of the body. Most people can get adequate iron from their diets, but some may need an iron supplement to prevent or treat anemia, a deficiency of red blood cells. Due to possible risks, iron supplements should not be taken without medical advice. If you believe you lack iron, contact your physician.
Increased Risk of Heart Disease
Some evidence links high iron stores with heart disease, according to the Office of Dietary Supplements of the National Institutes of Health. Researchers have observed a lower incidence of heart disease in populations that have lower levels of iron in the body, in frequent blood donors and in pre-menopausal women, who lose blood each month through menstruation. Excess iron levels have also been linked to diseases such as diabetes, cancer, increased risk of infection and rheumatoid arthritis, according to Peace Health. It is suspected that excess iron produces free radicals, substances that cause tissue-damaging inflammation. To avoid the possible risk of disease, take an iron supplement only if you are iron deficient, in an amount prescribed by your physician.
Iron Poisoning
Iron poisoning is the leading cause of deadly poisoning in children under 5, according to Merck Manual Home Edition. Many people have vitamins that contain iron or iron supplements in their homes, and if they are kept within reach of toddlers and children, the consequences can be serious. Liver damage, scarring of the stomach or intestines or death can result. Any supplements containing iron must be kept out of the reach of children. As little as 200mg of iron can fatally poison a child, according to Peace Health.
Stained Teeth
Iron supplements in liquid form may stain the teeth. To prevent staining, take liquid iron by mixing it with water, tomato juice or fruit juice, according to Drugs.com. Using a straw while drinking this preparation will help keep the iron away from the teeth. If liquid iron has to be given by dropper, place the dose toward the back of the tongue and follow it with juice or water. Iron stains are usually temporary, and can be removed by brushing the teeth with baking soda or medicinal-strength hydrogen peroxide.
