Lactoferrin is a multifunctional protein found in the milk of most mammals, with human milk containing significantly higher concentrations than cow's milk. This iron-binding glycoprotein plays an essential role in innate immunity and iron regulation. While most associate it with dairy, the origins of lactoferrin are more diverse, spanning both biological processes and modern biotechnological innovations.

A study published in the journal *Nutrients* highlighted lactoferrin's ability to increase iron bioavailability more effectively than standard iron supplements in some cases, prompting the critical question: which lactoferrin is best for iron absorption? The answer lies in understanding the different forms and their unique mechanisms of action.

Lactoferrin, a glycoprotein found in milk and other bodily fluids, is capable of binding two ferric iron ($Fe^{3+}$) ions per molecule. The specific iron saturation level of lactoferrin is not a fixed value but exists along a continuum, dictating its stability and function in the body.

Lactoferrin is generally recognized as safe (GRAS) by the FDA, yet excessive doses can lead to potential gastrointestinal side effects and other minor issues. While the protein offers many health benefits, understanding the risks associated with high intake is crucial for safe supplementation.

Lactoferrin was first identified in cow's milk in 1939 and is a key component of the mammalian innate immune system. It is a powerful, naturally occurring glycoprotein found in various body fluids, including milk, that plays a crucial role in regulating iron metabolism and protecting against infections.

The highest concentration of lactoferrin is found in human and bovine colostrum, the first milk produced after birth. Determining the best source of lactoferrin depends on your specific health goals, dietary needs, and whether you prefer obtaining this potent immune-boosting protein from whole foods or a concentrated supplement.

Naturally present in human and cow's milk, lactoferrin is generally well-tolerated as a dietary supplement, but understanding what are the side effects of lactoferrin is crucial for safe use, especially since higher doses have been linked to mild gastrointestinal symptoms.

Human colostrum, the first milk produced after birth, contains the highest concentration of lactoferrin, a multifunctional iron-binding protein crucial for innate immunity. Understanding what has the most lactoferrin is key for those seeking to enhance their immune system, improve iron absorption, or support gut health through diet or supplementation.

Clinical studies show that lactoferrin is generally well-tolerated, with some research indicating that consuming it from cow's milk may be safe for up to one year. This raises a critical question for many users: How long is it safe to take lactoferrin?

The highest concentration of lactoferrin, a potent iron-binding protein, is found in colostrum—the first milk produced after birth—for both humans and mammals like cows. For those seeking immune and iron-absorption benefits, understanding **how can I get lactoferrin naturally** from everyday foods is a crucial first step.
