Lactoferrin

Lactoferrin is an iron-binding protein found in human and cow's milk, saliva and tears. It is studied for its roles in microbial defense and inflammation.

What if you have a milk-protein allergy?

The French food-safety assessment could not exclude allergy to bovine lactoferrin and noted that the ingredient also contained small amounts of other milk proteins. Cow’s-milk origin is therefore a relevant safety detail for someone with milk-protein allergy. 1

How should the safety evidence be read?

EFSA judged bovine lactoferrin safe under the proposed food uses and levels it assessed. That conclusion does not establish unrestricted safety at any dose or in every clinical population. 2

Why is infant use a separate question?

In ELFIN, two serious events in the lactoferrin group were considered possibly related to the intervention: blood in stool and a death following intestinal perforation. These were possible associations, not proven causation, but they belong alongside the trial’s absence of infection benefit. 3

Which safety questions remain outside this review?
