The effects of intravenous iron supplementation on fatigue and general health in non-anemic blood donors with iron deficiency: a randomized placebo-controlled superiority trial.

ABSTRACT: We investigated whether intravenous iron supplementation improves fatigue and general health in non-anemic repeat adult blood donors with iron deficiency (ferritin???50 µg/L). Of 1,487 potentially eligible participants, 203 were randomly assigned to a single intravenous dose of 800 mg iron-carboxymaltose and 202 to placebo; 393 participants completed the trial. At 6 to 8 weeks after intervention, self-rated mean fatigue scores (numeric rating scale from 1-10, primary outcome) were 3.9?±?1.8 in the iron supplementation group and 4.0?±?2.2 in the placebo group, showing no group difference (p?=?0.819). Pre-specified subgroup analyses of gender, ferritin?
