Vitamin D levels appear to play role in COVID-19 mortality rates.

Vitamin D levels appear to play role in COVID-19 mortality rates.Patients with severe deficiency are twice as likely to experience major complications.Researchers analyzed patient data from 10 countries. The team found a correlation between low vitamin D levels and hyperactive immune systems. Vitamin D strengthens innate immunity and prevents overactive immune responses. The finding could explain several mysteries, including why children are unlikely to die from COVID-19. The researchers noted that patients from countries with high COVID-19 mortality rates, such as Italy, Spain and the UK, had lower levels of vitamin D compared to patients in countries that were not as severely affected.
