Lactoferrin (LF)
A multifunctional iron-binding glycoprotein found in milk and mucosal secretions. Has antimicrobial, immunomodulatory, anti-inflammatory, and prebiotic properties.
Mechanism of Action
Lactoferrin sequesters iron (depriving bacteria), disrupts bacterial membranes, modulates immune cell function, and promotes beneficial gut bacteria. It also has antiviral and anti-inflammatory properties.
Health Claims & Evidence
Broad-spectrum antimicrobial and antiviral effects
Immunomodulatory effects
Supports gut health and microbiome
Short-Term Effects
Improved immune function, reduced infection susceptibility.
Long-Term Effects
Sustained immune optimization and gut health support.
Side Effects
Generally very well-tolerated. Rare GI symptoms.
