Some of our favorite polyphenol-rich foods, including green tea, muscadine grapes, cacao, and dark chocolate appear to block an enzyme in the SARS-CoV-2 virus, inhibiting its replication. A docking simulation and in vitro study published in Frontiers in Plant Science found that these flavan-3-ol and proanthocyandin-containing foods can block and bind the function of this enzyme, or protease, which…
Supplementing with melatonin may decrease the likelihood of contracting COVID, particularly among African Americans. Researchers analyzed data from an observational study of over 26,000 people from a COVID-19 registry at the Cleveland Clinic Health System and found that melatonin use is associated with a 52% reduced likelihood of a positive SARS-CoV-2 test in African Americans.…
People who have been exposed to a seasonal “common cold” may experience less severe COVID-19 symptoms. While we’ve discussed this topic previously, a study from the Journal of Clinical Investigation reports the first clinical evidence of cross reactivity with the common cold and COVID. This is due to previous immune responses against the four endemic…
Three months ago, the prestigious medical journal The Lancet published, and then later retracted, a study on the use of hydroxychloroquine for COVID-19. The retraction was prompted by questions that were subsequently raised about the integrity of the data used for analysis from a database called Surgisphere, especially when it turned out that none of…
Protective antibodies against COVID-19 may only last a short time after infection, new evidence shows. However, it doesn’t mean that scientists have definitively answered the question about lasting immunity for this particular virus. The current thinking is that even low levels of powerful neutralizing antibodies may still be protective – after all, the immune system…
