The amino acid, L-Lysine, has had known antiviral properties since the 1980's when it was used to successfully treat herpes. Lysine inhibits Arginine absorption in the intestine, resulting in inflammation reduction. It may also be effective in treating and preventing cold sores. Because it is a known antiviral, is it possible that it is effective in treating or preventing the infection known as SARS-CoV-2?
In one study approximately 80% of acute stage covid-19 sufferers given Lysine displayed a minimum of 70% reduction in symptoms in the first 48 hours.
