The Truth about Vitamin D, Zinc, and Coronavirus Covid-19


Coronavirus Covid-19

There’s a lot of misinformation and half-truths going around right now about the novel coronavirus. That’s understandable — the virus is very new and doctors and scientists are still learning about how the infection works and the best ways to treat it. The news being reported about tests, symptoms, and treatments is conflicting at times, which is confusing. Plus, everyone wants to protect themselves as best they can, so it makes sense that people will try anything to stave off the virus, proven or not.

Will Zinc Supplements Protect Against the Coronavirus?

There is no research yet on whether zinc will impact the novel coronavirus, officially named SARS-CoV-2. However, zinc may interfere with the other six coronaviruses, including the original SARS and the four coronaviruses that cause the common cold.


Whether zinc can prevent infections hasn’t been studied as much as its therapeutic properties. A study from 2010 in cells in a dish — which, it’s important to point out, is not full people — found that zinc blocked replication of the first SARS coronavirus. In humans, however, the data is conflicting. One meta-analysis of seven different studies found that zinc supplements shortened the duration of a cold, which may have been caused by either a coronavirus or a rhinovirus, by 33%. A more recent double-blind, placebo-controlled trial published by the same scientist did not see any difference in cold symptom duration between people who took zinc and those who took a placebo.

Just because you can hold your breath for 10 seconds does not mean you haven’t been infected with the coronavirus.

“If there is an effect of zinc just on common colds, it’s pretty modest, and there’s no information at all about zinc and this particular coronavirus,” says infectious disease expert William Schaffner, MD, a professor of preventive medicine at the Vanderbilt University School of Medicine. “I’m going to repeat this again: Even if there were an effect, it’s only modest. You can’t take zinc supplements in lieu of doing anything else.”

Verdict: If you feel yourself getting sick, it might be worth taking zinc supplements, but they won’t prevent you from getting the virus.

What about Vitamin D?

Former CDC director Tom Frieden, MD, published an opinion piece on Fox News this week stating that taking vitamin D supplements could help boost the immune system, an essential piece of the puzzle in terms of how serious Covid-19 can be.

Vitamins are critical to keeping the body, especially the immune system, healthy. If you are vitamin deficient, it’s a good idea to take a supplement; however, very few people in the U.S. actually are deficient. One notable exception may be vitamin D.

Verdict: If you’re worried about your vitamin D levels or been told by a doctor you’re deficient, taking a supplement makes sense. But please don’t go to your doctor asking for a test now, and taking vitamin D isn’t an excuse not to be obsessive about hand-washing and adhere to social distancing.

Is It Dangerous To Take Ibuprofen In The Time Of Coronavirus?

Elemental has covered this in-depth elsewhere, but there is no published evidence that non-steroidal anti-inflammatory drugs like ibuprofen suppress the immune system or exacerbate Covid-19.

Verdict: Either ibuprofen or acetaminophen (Tylenol) are safe and effective to alleviate pain and fever.



Can Gargling With Warm Salt Water Or Drinking A Lot Of Water Protect Against The Virus?

Gargling with warm salt water is a tried-and-true home remedy to relieve symptoms of a sore throat, but that’s pretty much all it can do. It does not work as an antiviral to prevent or resolve an infection. (Also, a sore throat is not a common symptom of Covid-19.)

“If you want to gargle with salt water three times a day, fine. That will make your throat feel better, but it won’t protect your throat against the virus,” Schaffner says.

Hydration is definitely important if you’re sick, especially if you have a fever or diarrhea, which can cause the body to lose moisture even if you’re not sweating. There’s no evidence, however, that drinking water will wash the virus out of your mouth and prevent you from getting sick.

Verdict: Gargle salt water if you have a sore throat to relieve your symptoms, and drink water because it’s good for you and hydration is important. Neither of these acts will protect you from the coronavirus.

Will The Sun Kill The Coronavirus With Heat And UV Light?

Many viruses, including the original SARS coronavirus, are destroyed by high heat (above 132 degrees Fahrenheit) and UV light. In fact, some hospitals regularly use machines emitting UV light to sanitize rooms and equipment. However, it’s not yet confirmed if the novel coronavirus, SARS-CoV-2, acts in the same way. More importantly, the heat and UV rays from the sun are not strong enough to have this effect. Being outside on a sunny day will not destroy viral particles or prevent you from getting infected.

“Heat and ultraviolet light don’t act rapidly enough to interrupt the transmission between people,” says Schaffner. “If you’re standing within three feet of me, and I breathe out the virus, by the time you breathe in the virus, even if we’re in blinding sunlight, the virus has not been killed yet.”

Verdict: Although extreme heat and UV light may kill the novel coronavirus, being outside in the sun will not.

Can You Self-Diagnose Covid-19 By Holding Your Breath For 10 Seconds?

This is another question that Schaffner says makes sense on the surface. If you have severe Covid-19 with pneumonia, your lungs are impaired and you’ll have to work harder to breathe. At that point, you probably won’t be able to hold your breath for 10 seconds because you’ll need to breathe more frequently to get good air in and bad air out.

The test will not tell you anything if you have been infected but have no symptoms or symptoms without a cough, which there are increasing reports of early on in the course of the illness.

Verdict: Just because you can hold your breath for 10 seconds does not mean you haven’t been infected with the coronavirus.
