The Surprising Link Between Covid and a Vitamin D Deficiency

As the winter season approaches, people will stay indoors for longer periods of time. As the days get shorter, it’s critical we continue getting our vitamin D. Consider the following:

  • Did you know over 1 BILLION people worldwide have a vitamin D deficiency?
  • Approximately 42% of the US population is vitamin D deficient with some populations having even higher levels of deficiency,
  • Mounting evidence suggests that a vitamin D deficiency could be linked to several chronic diseases, including cardiovascular disease and cancer. 
  • Did you know there is a potential link between a vitamin D deficiency and the severity of covid?

Much as been written about the link between the severity of covid and a vitamin D deficiency, Many of these studies don’t get discussed in mainstream media.

Covid and Vitamin D: The Studies

Here are a few scientific studies discussing the link between covid and a vitamin D deficiency:

#1. Vitamin D and the immune system: “Vitamin D deficiency is a global public health issue. About 1 billion people worldwide have vitamin D deficiency, while 50% of the population has vitamin D insufficiency.

#2. Increased risk for COVID-19 in patients with vitamin D deficiency: Vitamin D deficiency is significantly associated with increased risk for COVID-19.

#3. Vitamin D deficiency and COVID-19: A case-control study at a tertiary care hospital in India: “Vitamin D status appears to be strongly associated with COVID-19 clinical severity. After COVID-19 confirmation, Vitamin D level should be measured in all patients and curative plus preventive therapy should be initiated.

#4. Vitamin D and Its Potential Benefit for the COVID-19 Pandemic: There are a growing number of data connecting COVID-19 infectivity and severity with vitamin D status, suggesting a potential benefit of vitamin D supplementation for primary prevention or as an adjunctive treatment of COVID-19.

#5. Vitamin D: National Institutes of Health: “Vitamin D has other roles in the body, including reduction of inflammation as well as modulation of such processes as cell growth, neuromuscular and immune function, and glucose metabolism.”

In this video, I discuss the studies that indicate a vitamin d deficiency plays a key role in the severity of covid:

Top Sources of Vitamin D

As the days get shorter, it may be difficult to get vitamin D from sunlight. As a result, making an effort to consume foods rich in vitamin D as well as supplements should be considered.

Here are the top food sources of vitamin D:

  • Egg yolks
  • Canned fish
  • Breakfast cereals
  • Shiitake mushrooms
  • Orange juice (fortified)
  • Cheese
  • Milk: whole, nonfat or reduced fat
  • Wild-caught fish
  • Yogurt
  • Eggnog
  • Almond milk
  • Beef or calf liver

Many vitamin D supplements are available as well:

Call To Action

When the temperatures drop, many people will spend more time indoors and in close proximity to others. This is important because many studies have linked the severity of covid to a vitamin D deficiency. Eating foods rich in vitamin D and supplements may help keep vitamin D levels elevated.

A strong immune system is the foundation to good health, and vitamin D is just one of many nutrients we need. Get more tips in my book The Diet of Success: Healthy Eating Tips For Hard Working Professionals. Available on Amazon.
