Improving Iron Status Without Iron: Clinical Insights From Recombinant Human Lactoferrin Supplementation

Helaina human lactoferrin (LF) (effera®) is a potential, well-tolerated alternative for improving iron status in women who present with chronic iron deficiency. This case series reports on two active women who had persistently low iron levels and poor response to, or intolerance of, standard orally administered iron supplements. The two individuals independently started oral ingestion of effera® at 100 mg/day for 6-20 weeks. Both showed notable increases in ferritin, with one also exhibiting marked increases in serum iron and transferrin saturation. The two participants reported better energy, fewer symptoms, and improved exercise capacity, all without gastrointestinal issues. These results align with growing evidence that LF supports iron homeostasis through receptor-mediated absorption, hepcidin-ferroportin modulation, and immune-balancing effects, potentially surpassing or working in synergy with conventional treatments. While limited to case reports, these observations support further controlled trials of effera® as an adjunct or alternative for iron deficiency, including non-anemic presentations.
