For acne, Lactoferrin earns evidence grade C (small effect, mixed consistency) — the evidence is limited or mixed. Modest

By sequestering iron it starves pathogens and modulates the gut microbiome and immune signaling; it also aids iron delivery to the host.

Generally very safe (it's a food protein); rare GI upset. Bovine-milk-derived — a consideration for severe milk allergy.

A legitimately useful milk protein for iron status and gut immunity, with modest acne data. Reasonable, well-tolerated, evidence still building.
