Lactoferrin and Probiotics: what the research found
PubMed indexes 8 records that name Lactoferrin and Probiotics 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.
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.
“In this systematic review and NMA, moderate- to high-certainty evidence demonstrated an association between multistrain probiotics and reduction in all-cause mortality; these interventions were also associated with the best effectiveness for other key outcomes. Combination products, including single- and multiple-strain probiotics combined with prebiotics or lactoferrin, were associated with the largest reduction…”
“Bovine lactoferrin supplementation has minimal impact on microbiota composition/function in preterm infants receiving probiotics, and therefore, is unlikely to disrupt microbiota development.”
“The results showed that symptoms (vaginal discharge and itching), Nugent score and recurrence rate were significantly improved by probiotics mixture in association with lactoferrin. This alternative approach may represent a safe and effective remedy for the restoration of healthy vaginal microbiota in preventing recurrent BV.”

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

Names both Lactoferrin and Probiotics in its title.

“The results show that the investigated lactobacilli mixture in combination with lactoferrin represents a safe and effective adjuvant approach for reducing symptoms and recurrences of RVVC.”
Names both Lactoferrin and Probiotics in its title.
“Of 134 infants who received probiotics and lactoferrin, 11 developed NEC, while 26 of the 150 infants in group 2 developed NEC, and the difference was statistically significant (p = 0.023). Conclusion Probiotics and lactoferrin given orally to very low birth weight preterm infants were associated with a decreased rate of NEC.”

Animal study
“Diclofenac induced ileal mucosal lesions by activation of inflammatory and pro-oxidant mechanisms. These detrimental actions were prevented by the combination of lactoferrin with Bifidobacterium likely through the modulation of TLR-2/-4/NF-κB proinflammatory pathways.”
Names both Lactoferrin and Probiotics 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:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.
How to read this page
A literature summary, not guidance.
A study listed here is not proof that Lactoferrin and Probiotics interact. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen. Our timing guide and forms guide explain the general mechanisms.
