Lactoferrin and immune
For immune support, Lactoferrin is a supporting ingredient backed by research. A naturally occurring iron-binding protein found in milk and colostrum. Best studied for improving iron absorption with fewer side effects than traditional iron supplements, and for supporting immune and gut health. In clinical studies, lactoferrin modulates immune function via macrophage, neutrophil, and NK cell activation.
How much lactoferrin do you need
Research points to 100–600 mg as the effective range for lactoferrin. 100–300 mg/day for general immune/gut support. 250–600 mg/day for iron deficiency support. Enteric-coated or liposomal forms provide ~10× better absorption than standard capsules. Lower doses may provide some benefit, but most studies showing clear results used this range.
Which form absorbs best
Avoid lactoferrin powder — no gastric protection — partially degraded by stomach acid. Avoid colostrum — variable lactoferrin content, not standardized. The most bioavailable options are enteric-coated lactoferrin or liposomal lactoferrin.
What the research says
The clinical evidence for lactoferrin in immune is moderate. Multiple meta-analyses support iron absorption benefits with fewer side effects than iron supplements Learn more
