NCT05290298

Brief Summary

A preliminary open-label case report demonstrated the beneficial effects of an innovative nitrate-based nutritional formula on oxygen saturation in patients with COVID-19. Whether these initial findings are relevant in a more robust research design currently remains unknown. Therefore, the main objective of this randomized controlled trial was to analyze the acute effects of nitrate-based nutritional formula on peripheral SpO2, patient-reported outcomes, and safety indices in patients with acute COVID-19 infection.
