Iron % saturation

Iron Saturation, also called transferrin saturation (TSAT), shows the percentage of your iron-transport protein (transferrin) that is carrying iron. It reflects how much iron is immediately available to your tissues for energy, oxygen transport, thyroid function, and neurotransmitter synthesis.Low TSAT indicates iron shortfall from low intake, absorption issues, or blood loss. High TSAT signals oversupply or tissue release, raising the risk of oxidative damage and organ stress. Interpreting TSAT alongside ferritin, TIBC, and a complete blood count provides a clear, real-time picture of iron status for smarter, safer decisions. ‍
