Bioferrin® is a LACTOFERRIN ingredient from Glanbia — distinguished by milk-derived lactoferrin (iron-binding glycoprotein) with documented immune support, iron metabolism, and antimicrobial activity. Glanbia's branded form leverages their dairy ingredient expertise. Used for: immune support, iron metabolism, gut health, antimicrobial activity, infant nutrition.

Studied Dose 100-1000 mg/day lactoferrin (varies by application; immune support typical 100-300 mg)
Active Compound Lactoferrin (iron-binding glycoprotein, ~80 kDa)

Benefits

Immune Support

Lactoferrin documented immune-modulating effects — supports innate immunity, antibody response, immune cell function.

Iron Metabolism Modulation

Lactoferrin's primary biological function is iron binding and transport — modulates iron availability without contributing to iron overload.

Antimicrobial Activity

Lactoferrin sequesters iron from pathogens and has direct antimicrobial activity against bacteria, viruses, fungi.

Gut Health

Supports gut barrier function and beneficial microbiome composition.

Infant Nutrition Heritage

Lactoferrin is naturally abundant in colostrum and infant formula applications — established safety and efficacy in infants.

Glanbia Dairy Expertise

From world's leading whey/dairy ingredient supplier with established lactoferrin extraction technology.

Mechanism of action

1

Iron Binding and Transport

Lactoferrin binds two iron atoms with high affinity; modulates iron availability; sequesters iron from pathogens that need iron for growth.

2

Immune Cell Modulation

Activates NK cells, modulates T-cells, enhances antibody response.

3

Direct Antimicrobial Activity

Lactoferricin (peptide derived from lactoferrin) has direct membrane-disrupting antimicrobial activity.

4

Anti-Inflammatory Effects

Modulates inflammatory cytokines; supports tissue homeostasis.

5

Gut Barrier Support

Strengthens intestinal epithelial barrier; modulates gut microbiome.

Clinical trials

1
Lactoferrin for Immune Support — Multiple Trials
PubMed

Multiple lactoferrin trials on immune markers and infection rates.

Various populations including infants, elderly, immunocompromised.

Established immune support effects; reduced infection rates in some populations.

2
Lactoferrin for Iron Metabolism
PubMed

Lactoferrin trials on iron status and absorption.

Iron-deficient populations.

Modulates iron metabolism; supports iron status without iron overload risk.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated.
Mild GI distress (rare).
DAIRY ALLERGEN — milk-derived; AVOID with dairy/milk allergy.
Allergic reactions to lactoferrin specifically rare.

Important Drug interactions

Generally minimal drug interactions.
Iron supplements — lactoferrin modulates iron absorption.
Pregnancy — lactoferrin naturally occurs in colostrum; generally considered safe.
Lactation — lactoferrin natural component of milk; safe.
Children — established safety in infants and children.
DAIRY ALLERGY — AVOID.
