Cover Story: The severity of the symptoms associated with COVID-19 is highly variable and has been associated with circulating amino acids. We studied a sample of 736 participants from the Biobanque Québécoise COVID-19, with symptoms classified as mild, moderate or severe. We assessed the association between circulating amino acids and the odds of presenting mild vs severe symptoms as well as their accuracy to predict adverse outcomes. Out of 20 amino acids tested, 16 were significantly associated with disease severity. Phenylalanine had a fair ability to predict the occurrence of adverse outcomes, similar to traditionally measured laboratory variables. Overall, severe COVID-19 symptoms are associated with altered levels of many circulating amino acids hinting at global changes in nitrogen metabolism.  View this paper
