I am also not an infectious disease epidemiologist and I am not speaking on behalf of infectious disease epidemiologists. I have a PhD in Nutritional Sciences and my expertise is in conducting and interpreting research related to my field. Please consult your physician before doing anything for prevention or treatment of COVID-19, and please seek the help of a physician immediately if you believe you may have COVID-19. SUBSCRIBE This series is based on my free daily newsletter, COVID-19 Research Updates. As a result of the time it takes to produce an video or podcast from a newsletter I wrote up, there's a slight delay between when I publish the newsletter and when you watch or listen to this. When you subscribe to the newsletter, you get the latest of my research every single day as soon as it's ready to come out. You get references and links to the sources for all the information, and you immediately get an archive of all the past issues. You can sign up at chrismasterjohnphd.com/covid19-updates SUPPORT It would mean the world to me if you support this service by purchasing a copy of my ebook, The Food and Supplement Guide to the Coronavirus. The guide contains my most up-to-date conclusions about what we should be doing for nutritional and herbal support on top of hygiene and social distancing for added protection. Due to the absence of randomized controlled trials testing nutritional or herbal prevention, these are my best guesses for what is likely to work without significant risk of harm, based on the existing science. Many people have asked why I am charging for this instead of giving it away for free, given that this is a time of crisis and people are in need. Unfortunately, I have not been immune to the effects this virus has had on the economy. My revenue from my other offerings started falling in February, and by mid-March I had days where my revenue was zero. I have three people who work for me full-time, and I am doing everything I can to avoid laying any of them off. By mid-March I had depleted 75% of my emergency fund in order to avoid any layoffs, and without charging for the guide I would not have been able to hold out much longer. Charging for the guide has allowed me to keep everyone working, replete some of my savings, and devote myself to researching COVID-19 full-time. As a result I now publish this daily COVID-19 series and the free newsletter, am involved in the design of several clinical trials that are in the process of being submitted for registration now, and am able to continually update the guide for free whenever my research warrants it. By purchasing the guide, you are enabling me to continue devoting my skills to the most important issue we now face. I am genuinely grateful for your contribution.
