Transferrin saturation (TSAT) — optimal range for vegans & vegetarians

Ratio of serum iron to total iron-binding capacity.

Optimal range

25–45 %

How a value is read

Deficient< 20 %
Below optimal20 – 25 %
Optimal25 – 45 %
Above optimal45 – 50 %
Markedly high> 50 %

Bands are given in the marker's canonical unit; values in other units are converted automatically.

Why it matters on a plant-based diet

Shows the share of transferrin loaded with iron. Low saturation (<20%) confirms iron deficiency even when ferritin is borderline.

A single marker decides nothing

Deficiencies mask one another: high folate hides low B12, inflammation inflates ferritin, low zinc mimics iron deficiency. VEGALYSIS reads the whole picture and explains the links.
