Transferrin saturation
Stomach and gut healthTransferrin saturation is the percentage of transferrin that is bound with iron.
It reflects how much of the transport protein is being used.
Why this matters
Transferrin saturation reveals whether your body has enough usable iron. Low saturation can indicate iron deficiency, which may lead to fatigue and impaired oxygen delivery, while high saturation may suggest iron overload, which can damage organs over time. Monitoring this marker supports timely dietary, lifestyle, or medical interventions to maintain healthy iron balance and overall metabolic function.
