How are Transferrin and menopause related?

Transferrin is an iron transport protein whose blood levels are influenced by iron status, inflammation, and hormones. During menopause, estrogen declines and menstruation ceases, reducing monthly iron loss. This can lead to increased iron stores (ferritin) and potentially lower transferrin concentrations. However, the relationship is not directly or strongly established in clinical research; individual factors such as diet, inflammation, or genetic variants (e.g., in the HFE gene) are more important. A DNA or blood test measuring transferrin alone cannot reliably indicate menopausal status or personal risk of iron overload. The evidence is mostly mechanistic, based on physiological principles rather than large intervention studies. For individual assessment, iron parameters (ferritin, transferrin saturation) should be evaluated in the context of overall health, ideally under medical supervision.
