80 per cent Covid-19 patients in Spanish study had vitamin D deficiency

The researchers found 80 per cent of 216 Covid-19 patients at the Hospital Universitario Marques de Valdecilla had vitamin D deficiency, and men had lower vitamin D levels than women. Patients with lower vitamin D levels also had raised serum levels of inflammatory markers such as ferritin and D-dimer.  Vitamin D controls blood calcium concentration and impacts the immune system.

One approach is to identify and treat vitamin D deficiency, especially in high-risk individuals.
