A commonly used nutritional supplement that prevents fever

Health experts point out that nutritional supplements made from lactoferrin, a component of breast milk, can boost the immune system and fight colds and flu.

Nutritionist Emma Davies said: “Lactoferin is found naturally in the body, particularly in breast milk and colostrum.”

“Lactoferin is a glycoprotein that helps stimulate and improve the baby's immune system.”

As part of our defense system against viruses, our bodies continue to produce natural lactoferrin throughout our lives. It's found in our saliva, tears, and mucous membranes, and when we come in contact with someone with a cold, the lactoferrin in our eyes, nose, and mouth starts fighting back.

Unfortunately, if we're stressed or don't sleep or eat properly, the body's ability to produce it decreases and we become susceptible to infections and diseases. Although some dairy products contain lactoferrin, you need to consume large amounts to get any benefit.

Lactoferrin can be extracted from cow's milk, and many nutritional supplements are available on the market. But it is important to consult a doctor before using it, especially if you are suffering from a certain medical condition.
