Why do some people get really sick, even die from flu, while others don't?  

Colds and flu 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? 

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.

"This book should be in the hands of every ICU team fighting 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. Hyla Cass MD)

"Don't read this book if you want someone else to think for you. Do read this book if you want to think for yourself. If you were in any doubt about media propaganda or bias, this book arms you with the facts to make the choice for yourself." (Antony Haynes, Nutritional Therapist)
