24 Mar 2020 --- US-based Cardax is seeking strategic collaborations to develop astaxanthin for the treatment of COVID-19. A new white paper from the biopharmaceutical company lays out the potential role of the carotenoid in fighting the pandemic. According to Cardax, astaxanthin may hold promise for boosting the immune system and reducing the extreme inflammatory response that may lead to severe respiratory complications in subjects with COVID-19. However, the move has been met with caution from other companies in the space, who warn that the proposal could be “premature.”
