Iron and Lactoferrin: what the research found

PubMed indexes 8 records that name Iron and Lactoferrin together, either in the title or in an interaction, co-administration, or pharmacokinetic context. The key findings come first, in the authors’ own words, followed by every study with its design and PubMed link.

A summary of published research, not medical advice. A pharmacist can check any combination against your full list of medicines and supplements.

Key findings

What the studies concluded.

Reviews and human studies first. Each quote is the authors’ own conclusion about their study, not a NutriStack assessment, and a single study is not a consensus.

“Overall, astrocytic Lf overexpression inhibited neuronal ferroptosis through two pathways: reducing intracellular iron accumulation and promoting GPX4 expression via inhibiting chaperone-mediated autophagy (CMA)-mediated GPX4 degradation. Hence, upregulating astrocytic Lf expression is a promising strategy for combating AD.”

Fan et al. · 2024 · Human study · details

“However, to date, no resolutive therapy for iron disorders has been found. In this review, we outline the efficacy of Lactoferrin, a member of the transferrin family mainly secreted by exocrine glands and neutrophils, as a new emerging orchestrator of iron metabolism and homeostasis, able to counteract iron disorders associated to different pathologies, including iron deficiency and anemia of inflammation in…”

“Lactoferrin is a promising effective treatment with fewer side effects than oral elemental iron in children with IBD and IDA.”

The research

8 studies naming Iron and Lactoferrin.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

“However, to date, no resolutive therapy for iron disorders has been found. In this review, we outline the efficacy of Lactoferrin, a member of the transferrin family mainly secreted by exocrine glands and neutrophils, as a new emerging orchestrator of iron metabolism and homeostasis, able to counteract iron disorders associated to different pathologies, including iron deficiency and anemia of inflammation in blood, Parkinson and Alzheimer diseases in the brain and cystic…”

ReviewHuman subjects

“Moreover, Lf can act as an iron scavenger by both direct iron-chelation or the modulation of the main iron-related proteins. In this review, the complex interplay between viral hepatitis, iron homeostasis, and inflammation as well as the role of Lf are outlined.”

Mancinelli et al. · From the abstract

Names both Iron and Lactoferrin in its title.

Multifunctional iron bound lactoferrin and nanomedicinal approaches to enhance its bioactive functions.

Molecules (Basel, Switzerland) · 2015 · PMID 26016555

ReviewHuman subjects

“Apart for emphasizing on the specific beneficial properties of lactoferrin from each of these sources, the general antimicrobial, immunomodulatory and anticancer activities of lactoferrin are discussed here. Implementation of nanomedicinial strategies that enhance the bioactive function of lactoferrin are also discussed, along with information on lactoferrin in clinical trials.”

Kanwar et al. · From the abstract

Names both Iron and Lactoferrin in its title.

Lactoferrin and iron: structural and dynamic aspects of binding and release.

Biometals : an international journal on the role of metal ions in biology, biochemistry, and medicine · 2004 · PMID 15222467

ReviewHuman subjects

“What triggers release of the tightly bound iron, however, and why lactoferrin retains iron to much lower pH than its serum homologue, transferrin, has been the subject of much speculation. Comparisons of structural and functional data on lactoferrins and transferrins now suggest that the key factor comes from cooperative interactions between the two lobes of the molecule, mediated by two alpha-helices.”

Baker et al. · From the abstract

Names both Iron and Lactoferrin in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Iron, Lactoferrin, and several hundred other substances.

Log your routine, get reminders at the times you choose, and scan a label to add a product. The checker is a research and organisation tool, not a clinical decision aid.
