"Lactoferrin is a nutrient classically found in breast milk. It binds iron and is transferred via a variety of receptors into and between cells, serum, bile, and cerebrospinal fluid. It has important immunological properties, and is both antibacterial and antiviral."
Tactical Support
Multifunctional protein that has several balancing and restorative roles in the body
The Game-Changing Nutrient
Lactoferrin is already present within the body, so Leapfrog IMMUNE works in synergy with our bodies’ own natural immune systems
Dose
250mg per IMMUNE tablet
50mg per SNOOZE tablet
Form
Bovine Lactoferrin (bLf) is lactoferrin sourced from cow’s milk. Its similarity to human milk (up to 75% homology) means it shares many of the same therapeutic benefits
Antimicrobial
Prevents viruses and bacteria from entering healthy cells and replicating
Bacteriostatic
Binds iron to itself, starving viruses and bacteria of the iron they need in order to survive and thrive
Bactericidal
Binds to bacterial walls and kills bacteria
Stimulates Innate Immunity
Enhances the body’s immune response & improves the activation of white blood cells that respond to viruses and bacteria
Anti-Inflammatory
Prevents harmful immune and inflammatory responses
Immunomodulatory
Stimulates the immune system to act against germs and moderates our response to infections (maintains immune homeostasis and prevents the immune system going into overdrive) Also, helps us recover more quickly from infection.
Gut Health
Promotes the growth of selected probiotic strains
Facts & Figures
