Main iron transport protein in blood.
| Genotype | Impact | What it means |
|---|---|---|
| GG (Normal) | Normal | Normal transferrin levels - typical iron transport. Maintain balanced iron intake (lean meat, legumes, leafy greens). |
| GA (Carrier) | Low impact | Slightly altered iron transport. Pair iron-rich foods with vitamin C; if you feel fatigued, check ferritin and transferrin saturation. |
| AA (Variant) | Moderate | May have lower serum iron despite adequate intake. Combine iron-rich foods with vitamin C, avoid tea/coffee at meals, and monitor iron status if symptomatic. |
