Frequently Asked Questions

How is lactoferrin different from colostrum?

Lactoferrin is one of the key bioactive components found in colostrum, but as a standalone supplement it provides concentrated, standardized doses of this specific immune protein. Colostrum contains lactoferrin plus immunoglobulins (IgG), growth factors, and other bioactives in a whole-food matrix. If your primary goal is antimicrobial defense and iron support, isolated lactoferrin is more targeted. For broader immune and gut benefits, colostrum provides a wider range of bioactives including lactoferrin.

Can lactoferrin replace iron supplements?

For mild iron deficiency or prevention, lactoferrin is an excellent alternative that improves iron absorption and status without the constipation, nausea, and oxidative stress of ferrous sulfate. An RCT in pregnant women showed equivalent efficacy with fewer side effects. However, for severe iron deficiency anemia, prescription iron supplements may still be needed for faster repletion. Lactoferrin can be used alongside iron supplements to enhance absorption and reduce side effects.

Is lactoferrin safe for people with lactose intolerance?

Yes. Lactoferrin is a protein, not a sugar, so lactose intolerance (which involves inability to digest lactose sugar) does not affect lactoferrin tolerance. Bovine lactoferrin supplements are highly purified and contain negligible lactose. However, individuals with a confirmed cow milk protein allergy should avoid bovine lactoferrin as it is itself a milk protein.
