Flu Fighters

Flufighters explains why some people get really sick, even die from flu, while others don’t? I used the first two weeks of ‘lockdown’ to write exactly what works - how to win the cold war and boost your immunity with natural non-toxic nutrients.

Colds and flu, including COVID-19, are viral diseases that a healthy immune system should be able to fight off with natural immunity. But what is a healthy immune system and how can you promote your own immune power with diet and nutrients?

What the book covers

This book explains:

  • How viruses work and where are their weaknesses
  • Why animals that make vitamin C rarely succumb to flu or colds.
  • The truth about vitamin C and how to use it when you’re infected.
  • How black elderberry blocks viral replication.
  • Why vitamin D levels crash in winter to make us more susceptible.
  • Other critical immune support nutrients from selenium to zinc.
  • How intravenous vitamin C saves lives in those with respiratory distress.

You’ll also discover how to restore and maintain a healthy immune system when not infected, complete with recipes for foods and drinks, and what to eat, drink and supplement when you are under attack to shorten duration and severity of colds and flu.

In 2020 the C4UK Campaign was launched. Vitamin C is a safe, inexpensive and highly effective anti-viral nutrient in the right amount, both for prevention of colds, reducing duration and severity, and for the treatment of COVID-19 in the acute phase with life-saving potential. Yet it is classified as ‘fake information’, not recommended by governments and rarely prescribed by doctors. This has to change. Sign our petition.

“This book should be in the hands of every ICU team fighting COVID-19 and other infections. 

Informative, well-written, and research-backed. It shows you how to take charge of your own immunity in the midst of this deadly world-wide pandemic.”

Dr Cass, MD, Los Angeles, USA

“This expert deep dive into the inner workings of vitamin C explains why claims that it is a natural defender against viruses such as COVID-19 make perfect sense.”

Jerome Burne, award-winning medical journalist

Other Approaches to Covid

Vaccination is one approach to covid, triggering acquired immunity. But what else can be employed a) to support innate immunity and b) to supress viral replication? In this month’s podcast I’ll be updating you on three strong candidates – vitamin C, vitamin D and the anti-parasite drug Ivermectin – by talking to vitamin D expert Dr David Grimes and Ivermectin expert Dr Tess Lawrie as well as updating you on a review of 12 vitamin C for covid trials.

David Grimes qualified in medicine at Manchester University in 1966. He was appointed Consultant in General Medicine and Gastroenterology in Blackburn, Lancashire, in 1977 and he finally retired at the end of 2014. He was concerned about the geographic, social and ethnic variations in health affecting his patients and the local population, and this led to a long research interest that identified the immense importance of vitamin D in our health.

Dr Tess Lawrie is founder of the British Ivermectin Recommendation Development Group (bird-group.org), is the Director of the Evidence-Based Medicine Consultancy Ltd, and founded the community interest company EbMCsquared this year to address the public need for transparent and objective research related to covid-19 therapeutics. She is author of over 80 published research papers and is committed to improve the quality of healthcare globally through rigorous research as a founder member of the World Council for Health.

All Things Covid

Today my podcast guest is the award-winning medical journalist Jerome Burne who has exposed many a scandal, been first to the press with numerous breakthroughs, both in complementary and mainstream medicine.

His latest piece, in the Daily Mail last month was on Long covid. In this podcast, we’re going to discuss all things covid related, from vaccines to vitamins, long covid, anti-viral drugs such as Ivermectin, and the politics behind the current and alternative approaches to the pandemic.

Nutritional Approaches to Long Covid

In my latest podcast I am joined by Professor Shirley McIlvenny, a doctor originally from Northern Ireland but now on the Gold Coast of Australia who works at the National Institute of Integrative Medicine and has been both a Professor of Family Medicine and Education. She is an expert in post covid, or long covid and how to recover naturally. Dr Shirley has a excellent online programme to take you through the process of speeding up recovery from long covid which includes very informative webinars and an e-book.

When you sign up here please use the code PH10 because Dr Shirley will both give you a 5% discount and donate 10% of your course fee to help fund our vitamin C care home study. [No-one has ever measured what elderly people in care homes actually need in the way of vitamin C. With almost half of all covid deaths in the first wave being in care homes we have to find out. Grandparents lives matter].



Can Vitamin C in Critical Covid Save Lives?

Can vitamin C in critical Covid save lives? That’s the topic of this podcast. I’m going to be talking to three of my co-authors of our review on vitamin C and Covid - Professor of Medicine Paul Marik, who is Chief of the Division of Pulmonary and Critical Care Medicine at Eastern Virginia Medical School and Dr Marcela Vizcaychipi, Head of Research in Intensive Care Medicine at the Chelsea and Westminster Foundation. But first, to give us a good background to the dynamics and the use of vitamin C in viral infection I’m talking to Associate Professor Anitra Carr who is Director of the Nutrition in Medicine Research Group at Otago University in New Zealand.




Vitamin C Trials in China: Combatting the Virus

Chinese hospitals have decreased deaths and increased survival. Why? With three trials under way, and a mandate from the Shanghai Medical Board to treat COVID-19 patients in ICU with high dose vitamin C, China are leading the way in effective treatment of respiratory distress. The first 50 preliminary cases show no deaths, no safety issues and faster recovery. I talk to Dr Cheng, in Shanghai, about the trials and what’s happening in hospitals in Wuhan.


UPDATE: Vitamin C saves lives - 3 Chinese hospitals report. The results from the trials in China are now available. 


How Vitamin C Reverses Respiratory Diseases: The Mechanism

How does vitamin C work to reverse acute respiratory distress - the life threatening syndrome that’s claiming lives? A new theory, proposed by research biochemist, Doris Loh from Hong Kong, explains close up how vitamin C works to effect recovery. We’ll learn about the different types of vitamin C, the doses that make a difference, the co-factor nutrients that help vitamin C restore your immunity and what to do if COVID-19 strikes you. [See Resources section to follow her work].



What We Know about Vitamin C and Infections: 60 Years of Science

Vitamin C is the most researched vitamin, with 60 years of evidence relating to colds, flu and other infections. An increasing body of evidence is showing that it can speed up recovery from pneumonia, shorten severity and duration of infections, as well as reducing need for ventilators and ICU care. At the forefront of razor sharp analysis of the scientific evidence for the past 40 years is Professor Harri Hemila, from the Department of Public Health at the University of Helsinki in Finland.



The Sharp End of Treatment - How Intravenous Vitamin C is Saving Lives

I’m going to be looking at the sharp end of viral infections and lung damage, talking to Dr Paul Marik, Professor of Critical Care Medicine at East Virginia Medical School in the US, Dr Anton in South Africa using intravenous vitamin C in lung disease, and Dr Shirley McIlvenny, formerly a UK GP now using intravenous and high dose vitamin C, and other nutrients to keep you healthy, now practising in Australia. [See Resources section to follow their work].


Patrick Holford in Conversation with Dr Thomas Levy

Vitamin C and the Importance for Your Immune Health and Beyond

I’m going to be joined by a man every nutritional therapist will know – Dr Thomas Levy, who wrote the book -more a compendium - called Curing The Incurable. It documents every study, be in the lab on cells, or in the clinic on people, on every viral and bacterial and infectious disease ever treated by vitamin C, going all the way back to the 40’s. With 80 years of research and 25 years of clinical practice using high dose oral and intravenous vitamin C, I can think of no-one better to conclude our first series of podcasts focusing on vitamin C and its potential for health, both for this pandemic and beyond.
