Active Iron capsules contain ferrous sulfate, a medicine used to treat and prevent iron deficiency. Iron is an essential mineral needed for the formation of haemoglobin, which carries oxygen around the body to the tissues and is used to release energy from food. Iron is also needed to metabolise other important vitamins and minerals such as vitamin c and calcium. Active Iron is a clinically proven supplement to help support healthy iron balance in the body. Its absorption rate is better than other competitive brands whilst being gentle on the stomach. Daily use of this supplement can contribute to increased energy levels and better cognitive function.
