Lactoferrin: The New Immune System Supplement on Experts’ Lips

Lactoferrin: The New Immune System Supplement on Experts’ Lips

Written by Leapfrog

As we slide into autumn and begin to mingle indoors again, the dreaded coughs and colds are likely to come home with us. This time last year, because of social distancing and wearing masks, cold and flu season was mild, so this autumn/winter our immunity against viruses is especially low. How can we protect ourselves against seasonal bugs?

Your Natural Defence System

Lactoferrin is an anti-viral, anti-bacterial and anti-inflammatory protein that your body makes daily, working in your eyes, nose, mouth & certain white blood cells to protect you against germs. But when we’re stressed, tired, run-down, not eating properly or simply ageing, our innate lactoferrin may be depleted faster than it's restored. This can leave us vulnerable.

Nature's Remedy®

Fortunately, we can take lactoferrin as a supplement. Lactoferrin is also a key component of mother’s milk and is created by nature to offer a newborn optimal immunity. Lactoferrin extracted from cow’s milk is biologically similar, allowing adults to access similar immune-enhancing benefits.

Leapfrog Remedies

An innovative supplement from the 1st lactoferrin brand in the UK, Leapfrog IMMUNE contains 250mg of lactoferrin per dose, plus zinc and vitamin C. Formulated as a citrus-flavoured chewable tablet, the effects begin in the mouth and bypass the harsh gastric juices. No water needed, and no big pills to swallow.


Over 12s and adults can take Leapfrog at the first sign of a scratchy throat or sniffle to nip it in the bud (2 tablets per day), or pulse throughout the season for prevention (1 tablet per day, month on/month off). A supplement that works in sync with your body, Leapfrog IMMUNE is a must-have in the medicine cabinet this autumn.

Now For The Science...

Over the past 3 years, lifestyle journalist Stephanie Drax (FT, Vanity Fair, Telegraph, House & Garden...) has worked with leading scientists and wellness experts to create Leapfrog IMMUNE: immunologist & lactoferrin expert Dr Marian Kruzel (University of Texas), pharmacist Dr Hamid Merchant (University of Huddersfield), nutritionist Emma Davies (NatureDoc Clinic), and Renée Elliott, the founder of Planet Organic.

There are over 9,100 peer-reviewed scientific studies extolling the benefits of lactoferrin. A study published in February 2021 entitled “The in vitro antiviral activity of lactoferrin against common human coronaviruses and SARS-CoV-2” (Hu et al, Emerging Microbes & Infections, 2021) reports that lactoferrin can keep multiple human coronaviruses at bay. Lactoferrin derived from cow’s milk – as Leapfrog’s lactoferrin is – can bind directly to the virus and inhibit its absorption into target cells. In addition, when the spike protein of a virus docks on an area on healthy cells called the heparan sulfate proteoglycans (HSPGs) before gaining entry into the cell, lactoferrin can block the virus at the HSPG site.

“In this work, we profiled the broad-spectrum antiviral activity of LF against multiple common human coronaviruses including HCoV-OC43, HCoV-NL63, and HCoV-229E as well as SARS-CoV-2 and its mechanism of action. It was found that LF inhibits not only SARS-CoV-2, but also HCoV-OC43, HCoV-NL63, and HCoV-229E.”


As SheerLuxe has said: "Immunity continues to be at the forefront of our minds, and as we slowly adjust to the ‘new normal’, it pays to have science on your side. Meet Leapfrog, the supplement brand taking the health world by storm."
