Breast milk is the best nutrition for infants. It is nutritionally complete and helps protect a newborn against infections. The World Health Organisation recommends breastfeeding for two years and beyond, even after a baby starts eating complementary foods. Breastfeeding is uniquely beneficial during this specific period and has a profound impact on long term health, including future gut and immune health outcomes 3. During the first days, extensive research supports the important role lactoferrin plays as a key dietary protein in breast milk. Lactoferrin is found in abundance in both colostrum and mature breast milk — the milk from approximately four weeks of age.

Overview of Lactoferrin in Breast Milk
Lactoferrin LF , also known as lactotransferrin LTF , is a multifunctional protein of the transferrin family. Lactoferrin is a globular glycoprotein with a molecular mass of about 80 kDa that is widely represented in various secretory fluids, such as milk , saliva , tears , and nasal secretions. Lactoferrin is also present in secondary granules of PMNs and is secreted by some acinar cells. Lactoferrin can be purified from milk or produced recombinantly. Lactoferrin is one of the components of the immune system of the body; it has antimicrobial activity bacteriocide , fungicide and is part of the innate defense, mainly at mucoses. Occurrence of iron-containing red protein in bovine milk was reported as early as in ;  however, the protein could not be properly characterized because it could not be extracted with sufficient purity. Its first detailed studies were reported around
The Essential Components of Breast Milk
Many of these cannot be found in formula. Immunoglobulins: All types of immunoglobulins are found in human milk. Secretory IGA, a type of immunoglobulin that protects the ears, nose, throat, and the GI tract, is found in high amounts in breast milk throughout the first year. Breast milk levels of IGA against specific viruses and bacteria increase in response to a maternal exposure to these organisms. Lactoferrin: Lactoferrin is an iron-binding protein that is found in human milk, but is not available in formulas.
Enzymes perform important functions that are necessary for survival including those involved in digestion and metabolism. Each enzyme has only one job, and it's specific to the type of chemical reaction that it produces. There are many different enzymes found in human breast milk. These enzymes play an important role in the health and development of a newborn child. The enzymes in breast milk serve a variety of functions, some of which we do not even know yet.
