Lactoferrin is a protein found in cow milk and human milk (breast milk).

How does it work?

Lactoferrin helps regulate the absorption of iron in the intestine and delivery of iron to the cells.The lactoferrin contained in mother’s milk is credited with helping to protect breast-fed infants against bacterial infections.

In addition to bacterial infections, lactoferrin is active against infections causes by some viruses and fungi.Lactoferrin also regulates bone marrow function (myelopoiesis), and boosts the body’s defense (immune) system.

Neuro is therefore almost like human breast milk, hence it is helps babies digest lactose easier.
