Common dosing range
100–600 mg/day depending on goal
When to expect effects
Weeks (anemia)
Watch out for
Most products are bovine-derived; avoid with severe milk protein allergy
What is it
Lactoferrin is an iron-binding milk glycoprotein found in colostrum, milk, and other secretions. Supplements typically use bovine-derived lactoferrin for immune, iron, and gut support.

iron deficiency anemia
Corrects deficiencyRandomized trials, particularly in pregnancy, show oral bovine lactoferrin raises hemoglobin and ferritin, sometimes with better tolerability than ferrous sulfate. Outcomes are blood iron markers; lactoferrin is used to correct deficiency rather than treat a disease independent of iron status.
Bottom line: Lactoferrin can correct iron deficiency anemia, often with fewer GI side effects than standard iron.
common infection burden
Supplement benefitSome trials suggest lactoferrin reduces the frequency or duration of common infections, consistent with its antimicrobial and immune-modulating activity. The evidence is limited and mixed across populations.
Bottom line: Lactoferrin may modestly reduce infection burden, but the evidence is preliminary.
helicobacter pylori adjunct
Disease adjunctAdding bovine lactoferrin to standard H. pylori triple therapy has improved eradication rates in some trials, though results are inconsistent. It is an adjunct, not a replacement for antibiotic therapy.
Bottom line: Lactoferrin may modestly improve H. pylori eradication as an add-on, but evidence is mixed.
Evidence is mixed
Some trials show higher eradication with added lactoferrin while others find no significant benefit.
How it works
How to take it
What to track
2 commercial forms
Compare the main delivery options and what they’re best suited for.
Apolactoferrin (iron-free)
Common form in immune-targeted products.
Higher iron-binding capacity in the gut.
Holo-lactoferrin (iron-saturated)
Used in some iron-support products.
Carries bound iron; may favor iron-delivery applications.
Safety
Know the common side effects, key cautions, and who should avoid it.
Common side effects
Who should avoid it
- people with severe milk protein allergy
Pregnancy & breastfeeding
Discuss pregnancy and infant use with a clinician; it has been studied for anemia in pregnancy.
Interactions
may influence iron absorption in either direction depending on context

Frequently asked questions
Is lactoferrin safe for people who are lactose intolerant?⌄
Usually yes. Lactoferrin is a protein, not lactose, and most products are processed to remove lactose, though they are still bovine milk-derived.
Does lactoferrin help with anemia?⌄
Trials, especially in pregnancy, suggest oral bovine lactoferrin can raise hemoglobin and ferritin with fewer side effects than ferrous sulfate.
