Iron

•  Iron is a mineral that is essential for good health. It plays several important roles in the body, including:
• Oxygen transport: Iron helps transport oxygen from the lungs to the rest of the body through the formation of hemoglobin and myoglobin in red blood cells.
• Energy production: Iron is necessary for the production of energy in the body as it helps in the metabolic processes of cells.
• Brain function: Iron is involved in brain function and cognitive development, particularly in infants and young children.
• Immune system function: Iron helps the immune system fight infections by supporting the growth and function of immune cells.

Most people can get enough iron from their diets by eating a variety of iron-rich foods, including red meat, poultry, fish, beans, lentils, tofu, fortified cereals, and dark, leafy greens such as spinach and kale. Some people, however, may need to take iron supplements to meet their needs, especially if they don't get enough iron from their diets or if they have certain health conditions, such as anemia. If you are considering taking an iron supplement, it's a good idea to talk to your doctor first to determine if it is right for you and to determine the appropriate dosage.
