Your guide to Iron Saturation.

What is Iron Saturation?

Iron Saturation or transferrin saturation is the ratio of iron levels to total iron binding capacity.‍In the blood, iron is carried by transferrin, but transferrin still has extra binding capacity.‍Measuring this ratio is more useful than either biomarker alone, and more accurately represents how well our body is managing its iron balance.

What does it assess?

Iron Saturation provides insight into how much of the body’s transport capacity for iron is being utilized.‍This metric is essential for understanding whether there is a balance, deficiency, or overload in iron levels.‍By examining iron saturation along with other iron metrics, it becomes possible to identify and manage conditions like anemia, hemochromatosis, and other disorders affecting iron metabolism.‍

How do I optimize my Iron Saturation?

Vitamin C can increase non-heme iron absorption.‍Consuming vitamin C-rich foods, such as citrus fruits, bell peppers, and strawberries, with meals that contain iron can help increase iron saturation. For individuals with high iron saturation, it’s essential to avoid extra iron intake, including supplements, and to moderate iron-rich foods. Ensure a steady intake of iron from dietary sources. Include heme iron, as it is more readily absorbed, along with non-heme iron. For most individuals, a balanced diet with these foods can support optimal iron levels.

What does good and bad Iron Saturation look like?

Elevated iron saturation levels can indicate iron overload. This may be due to hereditary hemochromatosis or other conditions involving iron accumulation.‍High iron saturation can lead to iron deposits in organs such as the liver, heart, and pancreas, potentially causing organ damage if untreated.‍Low iron saturation levels suggest that the body is not receiving or absorbing enough iron, which may result from iron deficiency due to poor diet, chronic blood loss, or conditions that interfere with iron absorption.‍
