Iron What is it? (physiology and clinical effects) Iron is a trace mineral vital to the production of hemoglobin and myoglobin, a molecule that carries oxygen in the blood and muscle tissue. Iron is also important for many enzymatic reactions, for a healthy immune system, and for energy production. Iron-deficiency anemia is quite common in the United States. Clinically relevant conditions: Bleeding Canker sores Celiac disease Crohn's disease Depression Fatigue Growth retardation Iron-deficiency anemia Menstrual bleeding (excessive or prolonged) Restless leg syndrome Ulcerative colitis Food Sources: Liver and organ meats, beef, poultry, oysters, seafood, blackstrap molasses, legumes, dark-green leafy vegetables (especially spinach), kelp, dried fruit Risk factors and symptoms of deficiency: (who is likely deficient) Deficiency is caused by either insufficient intake, blood loss (i.e. intestinal bleeding or with excessive menstruation), or poor absorption as with diets high in phosphorus, prolonged use of antacids, and excessive caffeine intake. Heavy exercise and excessive perspiration can also deplete iron from the body. Symptoms of iron deficiency include anemia, fatigue, brittle hair or hair loss, nails that are spoon shaped or have ridges running vertically, nervousness, difficulty swallowing, weakened immunity, digestive upset, cravings for indigestible substances such as dirt, pencils, or ice, dizziness, pallor, inflammation around the mouth, and poor memory and concentration. Recommended dosage: (how much usually taken) Men: 10 mg daily Women with normal cycle or no cycle: 10 mg Women with heavy cycle: 20 mg Contraindications:(side effects / precautions / interactions / drug interactions) Do not take iron supplementation if you have hemochromatosis. Signs of overdose include constipation and metallic taste in mouth. Do not take supplemental iron unless you have low iron levels seen with blood tests. Excessive iron has been associated with increased risk for developing heart disease, diabetes, and cancer. Vitamin C improves the absorption of iron.
