Lactoferrin is a type of protein that is naturally found in milk, as well as in other bodily fluids such as saliva and tears. It is known for its antimicrobial properties and ability to bind to and transport iron.
In protein powders, lactoferrin may be added as a supplement to help support immune function and promote overall health. It is believed to help support the body's natural defenses against harmful bacteria and viruses, as well as to have anti-inflammatory properties.
Lactoferrin is generally considered safe when consumed in recommended amounts.
