Iron is helpful for treating anemia, one of the most common nutritional deficiencies in the world. Anemia results when hemoglobin is below normal ranges. Symptoms of anemia include fatigue, dizziness, fast heart rate, and malaise, or an overall feeling of sickness and weakness.
The chief function of iron is to form hemoglobin, a red protein whose main purpose is to transport oxygen in the blood. Additional hemoglobin is important because humans lose blood in many ways, especially from injuries. Women lose blood every month during their menstrual cycles, which is one of the most common reasons women may be more likely to suffer from anemia.
Iron may help manage unexplained fatigue, which can affect both men and women. Even in someone who isn’t anemic, low iron can still reduce energy levels. This is especially common in women during their reproductive years. Iron-rich foods and supplements can help raise iron levels and eliminate feelings of tiredness and exhaustion.
