Several recent studies have looked at the impact of vitamin D and zinc on COVID-19.
One study of 489 people found that those who had a vitamin D deficiency were more likely to test positive for the virus.
Another study found that of 50 people with COVID-19 in the hospital, only one needed ICU treatment after being given high doses of vitamin D.
By this point, we’ve all seen patients in the hospital receive these supplements.
The most notable, President Trump, received a mixture of vitamin D and zinc along with a number of other experimental drugs.
Does it work?
According to the National Institutes of Health, because of the suspected benefits, availability and cheap cost, they’d like to find something this simple can cure or prevent coronavirus, but the truth is, it’s not proven yet.
Registered dietitian Erin Gussler explains the possible benefits, “They can help the immune system identify pathogens in the body, so helping the immune system recognize the virus in the body and they also are part of the immune system and the mechanism that blocks the viruses from being able to get into the cells.”
