Iron is a necessary component of hemoglobin, a protein that transports oxygen to the bodys tissues, and of myoglobin, which stores oxygen for use in muscle tissues.* Because it is required for electron transport in mitochondria, normal iron status is critical for energy production and body temperature regulation.* Immune system function and neurological health are also affected by iron status.* This product features Ferrochel®, a form of iron that has clinically demonstrated superior bioavailability and is unlikely to cause GI distress or constipation.*
