Synopsis

Source of validity: Scientific
Rating (out of 5): 5

Iron is scientifically validated as a treatment for fatigue, particularly when fatigue is due to iron deficiency or iron deficiency anemia. Iron is an essential mineral required for the production of hemoglobin, a protein in red blood cells that transports oxygen throughout the body. When the body lacks sufficient iron, the production of hemoglobin decreases, leading to reduced oxygen delivery to tissues, which manifests as fatigue, weakness, and decreased physical and mental performance.

Multiple randomized controlled trials and meta-analyses have demonstrated that iron supplementation in individuals with iron deficiency or iron deficiency anemia significantly improves fatigue and restores energy levels. For example, a 2012 systematic review in the CMAJ (Canadian Medical Association Journal) found that iron therapy improved fatigue scores in women with iron deficiency but without anemia. Similarly, the World Health Organization and numerous clinical guidelines recommend iron supplementation in populations at risk of deficiency, such as menstruating women, pregnant women, and individuals with chronic blood loss.

It is important to note that iron supplementation is not effective for treating fatigue unrelated to iron deficiency, and unnecessary supplementation can cause side effects or toxicity. Therefore, diagnosis of iron deficiency through laboratory testing is essential before initiating iron therapy for fatigue.
