What is Lactoferrin? The ‘miracle molecule’ you’ve never heard of.

Scientists have called lactoferrin a “miracle molecule”.

Lactoferrin is a wonder molecule and a key component of mother’s milk. Our bodies produce it as part of our innate immune system. We have been researching lactoferrin for over 15 years and we never cease to be amazed by it and the growing research into its antiviral, antibacterial, anti-inflammatory properties.

Lactoferrin also plays a key role in gut health – and immune defence begins in the gut!

Lactoferrin is a wonder molecule that we should all be taking – and we’re happy to finally be bringing it to you.

What Does Lactoferrin Do? 

Lactoferrin, a multifunctional bioactive protein predominantly found in bovine milk and human milk, is often hailed as a "phenomenon" in scientific circles. Its active role in immune function and regulation has garnered extensive attention for its potential health benefits. Containing 689 amino acids, researchers are particularly excited about lactoferrin's anti-inflammatory, antibacterial, and antiviral properties, which can bolster your immunity and aid in performance recovery.

Let’s look at the peer-reviewed research with a review of Lactoferrin's health benefits 

There are well over 10,000 articles about lactoferrin on PubMed (PubMed is an online database that provides access to a vast collection of biomedical literature).

1. Antiviral and Antibacterial Properties

Lactoferrin exhibits potent antimicrobial activity against a range of pathogens, viruses and various bacteria. A study by Kuwata et al. (2015) showed that lactoferrin binds to iron, a nutrient that harmful bacteria rely on to thrive, effectively depriving them of this essential element (Kuwata, K., et al. 2015. Lactoferrin: A Multifunctional Glycoprotein with Antiviral Activity. Biochemical Pharmacology, 93(3), 392-403). This property makes lactoferrin a valuable supplement for reducing the risk of infections.

2. Support of Immune Response

Lactoferrin plays a pivotal role in modulating the immune response. It enhances the proliferation and activity of lymphocytes, critical immune cells responsible for adaptive immunity. According to Gonzalez-Chavez et al. (2009), lactoferrin stimulates the production of cytokines—signalling molecules that regulate immune responses—leading to a balanced and robust immune defence against infections (Gonzalez-Chavez, S. A., et al. 2009. Lactoferrin: A Multifunctional Glycoprotein Involved in Immune Regulation. Journal of Immunology Research, 2010, 1-7).

3. Anti-Inflammatory Effects

Chronic inflammation is linked to numerous health issues, including autoimmune diseases and persistent infections. Research by Baker et al. (2007) highlights lactoferrin's anti-inflammatory properties, showing that it can reduce the production of pro-inflammatory cytokines while promoting anti-inflammatory cytokine release (Baker, E. N., & Baker, H. M. 2007. Lactoferrin and the Immune System. Biochemistry, 46(9), 2537-2545). This balance is essential for maintaining overall immune function and health.

4. Support for Gut Health and the Gut Microbiome

The gut is a vital component of the immune system, housing a large number of immune cells. Lactoferrin has a prebiotic function so it supports gut health by promoting beneficial gut bacteria and restoring the gut mucosal lining while inhibiting harmful pathogens. A study by Abe et al. (2013) indicates that lactoferrin can enhance the growth of beneficial gut microbiota, which is essential for optimal immune function (Abe, F., et al. 2013. Beneficial Effects of Lactoferrin on Gut Health: An Overview. Food & Function, 4(3), 358-365). 

5. Antioxidant Properties of Lactoferrin

Lactoferrin also boasts antioxidant properties, which help protect cells from damage caused by free radicals. As we age, our ability to combat oxidative stress diminishes, leading to cellular damage associated with chronic diseases. A study by Pérez et al. (2013) emphasizes lactoferrin's role in mitigating oxidative stress and protecting cells from damage (Pérez, S., et al. 2013. Antioxidant Activity of Lactoferrin. Nutrients, 5(2), 236-256). IMMUNE SHIELD supplements features a high dosage of Vitamin C, also known for its powerful antioxidant effects.

 Lactoferrin is truly a remarkable protein with a wide array of health benefits that can significantly bolster our immune systems. From its potent antiviral and antibacterial properties to its role in modulating immune responses and promoting gut health, the evidence speaks volumes about its potential. Coupled with Vitamin C—a well-known antioxidant that further enhances immune function—lactoferrin supplementation can be a powerful ally in protecting your health. As we navigate an increasingly challenging environment, with modern stresses that deplete our natural immunity, integrating lactoferrin and Vitamin C into your daily routine could provide the support your body needs to thrive. Embrace the power of this ‘miracle molecule’ and fortify your defences naturally.

IMMUNE SHIELD contains 300mg of lactoferrin and 240mg of vitamin c to support immune function.
