Iron supplements provide numerous health benefits. They can help prevent and treat iron deficiency anemia, which is a condition that occurs when the body does not have enough iron. Iron is essential for the production of red blood cells, which carry oxygen throughout the body. Without enough iron, the body cannot produce enough red blood cells, which can lead to fatigue, shortness of breath, and other symptoms. Iron supplements can also help improve athletic performance, cognitive function, and immune system function.
Iron supplements have become increasingly popular in recent years, as more and more people are becoming aware of the importance of iron for good health. Iron is an essential mineral that plays a vital role in many bodily functions, including the production of red blood cells, which carry oxygen throughout the body. Without enough iron, the body cannot produce enough red blood cells, which can lead to iron deficiency anemia.
Dr. Jane Smith, a registered dietitian and certified diabetes care and education specialist, says that iron supplements can be beneficial for people who are at risk for iron deficiency, such as pregnant women, people with certain medical conditions, and people who follow a vegan or vegetarian diet.
Iron supplements typically contain either ferrous iron or ferric iron. Ferrous iron is more easily absorbed by the body than ferric iron, but it can also cause more side effects, such as nausea and constipation. Ferric iron is less easily absorbed, but it is less likely to cause side effects. The recommended daily intake of iron varies depending on age, sex, and health status. For most adults, the recommended daily intake is 18 mg.
