Iron supplements are a great way to support a healthy immune system. Iron is an essential mineral that helps the body produce red blood cells, which carry oxygen throughout the body. A lack of iron can lead to anemia, which can weaken the immune system and leave the body more susceptible to infections. Iron supplements come in many forms, including pills, capsules, and liquids. They are often recommended for people who are not getting enough iron in their diet, such as vegetarians and women who are pregnant or breastfeeding. It is important to talk to a healthcare provider before starting an iron supplement regimen, as too much iron can be harmful.
