Can Vitamin D Prevent COVID?

Since the start of the pandemic, people have been trying to figure out why COVID-19 can be deadly to some while manifesting as nothing worse than a common cold in others. One variable that has been isolated is Vitamin D.

Vitamin D has long been known to be an important factor in immune health, so it makes sense that it could help combat a virus that preys on weak immune systems. Several studies have shown that those hospitalized with severe COVID symptoms are much likelier to have Vitamin D deficiencies than their asymptomatic counterparts. Unfortunately, about 40% of Americans do not get enough Vitamin D on a daily basis. To make matters worse, it is harder to get the necessary amount of Vitamin D while being locked up indoors and removed from natural sunlight.

Right now, your best option is probably to take Vitamin D supplements. As former U.S. Surgeon General Richard Carmona recently put it:

“Identifying and eradicating vitamin D deficiency with early and aggressive supplementation in COVID-19 has the potential to save thousands of lives and should be one of our highest public health priorities.”

After a year of research, the body of evidence supporting the claim the supplementation of Vitamin D can ward off COVID continues to grow. Luckily, with a prophylactic measure like this, you do not need to wait for a doctor’s prescription. You can go out right now and get your own Vitamin D supplements to take each morning. At the very least, you know it will improve your immune health.
