Abstract
Taurine is an amino sulfonic acid that is implicated in numerous physiological functions, including the regulation of oxidative stress, which plays an important role in coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), together with other pathophysiological processes. The recent finding of decreased serum taurine levels in SARS-CoV-2-infected patients, in tandem with its potential modulatory role in COVID-19 due to its antiviral, antioxidant, anti-inflammatory, and vascular-related effects, provides a rationale for considering taurine as a beneficial supplement in patients suffering from COVID-19. Here, we reviewed the potential disease-modifying effects of taurine and combined these with the current knowledge on COVID-19 to clarify the potential role of taurine in this respiratory disease.
