Science: Lactoferrin Can Stop A Summer Cold

Science: Lactoferrin Can Stop A Summer Cold

While we tend to think of winter as the sniffle season, summer has its own variety of viruses that can get you in their grip. Chances are you may feel worse in summer too, because of the perceived injustice of sneezing in the warm sunshine. No-one wants to be out of action in the summer time!

Summer colds are unique to hot seasons when heat stress can also play a part in suppressing the innate immune system. There are over 200 different types of virus that cause colds; whereas rhinoviruses and coronaviruses are often the winter cold culprits – and circulate all year round – enteroviruses are more common in the summer months. The symptoms include a running nose, coughing, sore throat, sneezing, headaches and body aches, all of which most people will recover from in 7 to 10 days.

At Leapfrog Remedies we keep up-to-date with the latest peer-reviewed scientific studies on our hero ingredient of Leapfrog IMMUNE: Lactoferrin. There are over 9,800 of them and counting, and come summer sniffles time we leap for joy about this one. It’s a randomised, double-blinded, placebo-controlled trial – the gold standard of trials – called Effects of lactoferrin on infectious diseases in Japanese summer (Oda et al, Journal of Microbiology, Immunology and Infection. 2020) In the study, 290 people supplemented with Lactoferrin for 12 weeks during the summer months, between June and September. The subjects who took 200mg or 600mg doses of Lactoferrin (extracted from cow’s milk) experienced significantly shorter summer colds than in the placebo group. The results were conclusive:

“In summer, the intake of Lactoferrin attenuates infectious diseases, including summer colds.”

Dr Hamid Merchant from the Department of Pharmacy at the University of Huddersfield agrees:

“The research from Japan shows that Lactoferrin can reduce the duration and severity of a summer cold. Lactoferrin (Lf) is one of the key immunomodulatory substances found naturally in various body fluids, such as saliva, tears, and breast milk, and forms a vital part of the innate defence against invading pathogens. Various studies have demonstrated the antimicrobial properties of Lf and its protective role in respiratory infections. Our own research has shown that Lf supplementation reduces the risks of respiratory infections and also has a beneficial role in symptomatic management and recovery.”

If You Catch A Summer Cold, DO THIS:

Social Distancing 

The first few days of symptoms are the most infectious and you can protect others from catching the infection.

Keep the windows open

Keep the air circulating through your home as much as possible.

Hand and oral hygiene

Avoid touching your eyes, nose and mouth if you haven’t washed your hands, as you pick up viruses from surfaces that have been sneezed on.

Get good rest

In the old days, pre-pandemic, we might have battled into the office with a bug. These days, we must put our health first and try to work from home if possible. Take rest, drink plenty of water and eat fresh fruits and veggies.
