Review of 14 global studies showing that the most frequently used dietary supplements during COVID-19 were vitamin C, vitamin D, zinc, and multivitamins. The most common reason was for improved immune system functioning or reduced COVID-19 risk. Authors note that participants who have attained higher education levels were more likely to use supplements during COVID-19.
Currently there are
107 vitamin D for COVID-19 studies, showing 36% lower mortality
[28‑44%], 26% lower ventilation
[-2‑46%], 50% lower ICU admission
[33‑62%], 20% lower hospitalization
[8‑31%], and 15% fewer cases
[6‑23%].
Currently there are
40 zinc for COVID-19 studies, showing 29% lower mortality
[9‑44%], 47% lower ventilation
[4‑71%], 26% lower ICU admission
[-9‑49%], 29% lower hospitalization
[7‑45%], and 22% fewer cases
[-10‑45%].
Currently there are
58 vitamin C for COVID-19 studies, showing 27% lower mortality
[13‑38%], 19% lower ventilation
[-8‑39%], 15% lower ICU admission

[3‑28%], and 8% more cases
