Some doctors and media channels argue that there is very little evidence to support the use of dietary supplements to prevent or treat COVID-19.  This guide provides our recommendations for nutritional defense against COVID. This version covers more than 150 studies that represent the best of science-backed strategies for nutritional interventions in the prevention and treatment of COVID-19. The supposedly gold standard of evidence in medicine is the randomised, controlled trial, or RCT. In RCTs, people are randomly given a treatment, or not. However, RCTs are expensive and takes time to implement i.e. requiring a minimum number of patients for the RCT to be 'adequately powered'. The first published Randomized Controlled Trial in medicine appeared in 1948 ( wikipedia ).  In the 21st century, evidence of medicine comes in many forms: Randomised controlled studies (RCT) Real world observational clinical stu

N-acetylcysteine (NAC) is a precursor to reduced glutathione, which appears to play a crucial role in COVID-19. According to an April 2020 literature analysis, 1  glutathione deficiency may be associated with COVID-19 severity, leading the author to conclude that NAC may be useful both for its prevention and treatment. NAC has a long history of use as a first-aid remedy for acetaminophen poisoning. It neutralizes the toxic effects of the drug by recharging glutathione, thereby preventing liver damage. But the idea that NAC can also be helpful against viral infections is not new. Previous studies 2 , 3  have found it reduces viral replication of certain viruses, including the influenza virus. In one such study, 4  the number needed to treat (NNT) was 0.5, which means for every two people treated with NAC, one will be protected against symptomatic infl
