Many people search for products that help support immunity and ward off colds. You may already be aware of the benefits of Echinacea and vitamin C for immunity. Lactoferrin is another supplement, relatively new on the market, which may assist with immunity.
What is lactoferrin?
Lactoferrin is one of the many proteins found in breast milk. This protein has been widely researched for potential uses in immunity and fighting of unwanted guests such as some bacteria and viruses.
Lactoferrin and immunity
What makes this lactoferrin so special is its ability to bind iron. By binding to iron, lactoferrin may decrease the amount of iron available to harmful bacteria. Bacteria needs iron to grow.
Lactoferrin and infants
As it is found in breast milk, lactoferrin is obviously supplied to newborn babies. Lactoferrin may help breast-fed babies fight off infections.
Lactoferrin and supplementation
For a long time, the only dietary source of lactoferrin was breast milk, but in the last few years, lactoferrin products derived from cow’s milk have emerged onto the market. This lactoferrin is known as bovine lactoferrin.
Bovine lactoferrin acts in the same way as human lactoferrin in that it strongly binds iron.
Preliminary in vitro and animal trials have also suggested that lactoferrin may directly stimulate some parts of the immune system. This new evidence gives an extra dimension to the use of lactoferrin in times of illness and even as a preventative measure.
Next time you are thinking of selecting a supplement to help you through the cold winter months, consider lactoferrin. Lactoferrin could well be a nutrient to add to your armoury that may help you possibly support your immune system.
