Lactoferrin, a minor fraction of whey,  appears to have a wide variety of uses in biological systems and is considered a first line of immune defense in the human body. Though a natural component of cows’ and human mothers’ milk, lactoferrin is found throughout the human body.22,23

Published studies examining lactoferrin as a supplement and its beneficial effects on immunity have been quite promising.24-26Lactoferrin helps maintain a proper level of “good” bacteria in the intestinal tract, while controlling the number of “bad” bacteria.27-30Lactoferrin is also known to have an extremely high affinity to bind to iron.22-32

Studies show that apolactoferrin, the iron-depleted form of lactoferrin, has unique benefits and may be superior to lactoferrin for supplementation.33 Life Extension’s lactoferrin supplement and whey protein powders contain only the superior apolactoferrin form of this important whey isolate.
