Iron has many health benefits. It is an essential mineral for your body to produce hemoglobin and myoglobin, two proteins that play a critical role in delivering and providing oxygen to different body cells. Iron may help maintain a good immune system and improve energy levels by providing oxygen to your body. Iron is found in nature in two forms: heme and non-heme. Non-heme iron is found in plant sources and is not as available for absorption as heme iron in animal sources. With the help of vitamin C, non-heme iron is able to be absorbed in the correct form in the body. Iron supplementation primarily works to restore low iron levels and treat iron deficiency anemia.
