Vitamin D predicts COVID-19 outcome

What is Vitamin D? 

Vitamin D, popularly referred to as the sunshine vitamin, or technically called calciferol, is emerging as a crucial variable in the body’s fight against the Covid-19 virus. 

Vitamin D is a fat-soluble vitamin naturally found in animal-based protein (such as the flesh of fatty fish, fish liver oils, beef liver, cheese, and egg yolks), added to “fortified” foods (such as cow’s milk, breakfast cereal, juices, and margarine) and available in various supplemental forms. Vitamin D is also produced within the body when ultraviolet rays from sunlight strike the skin and trigger the synthesis reaction from cholesterol. Despite its name, this “vitamin” is technically a hormone, with receptors in almost every cell and tissue in the human body, where it is responsible for regulating up to 200 genes.

Why is Vitamin D important?

Vitamin D is a crucial component to our daily health and is involved in both maintaining health as well as preventing the formation of disease states. 

-Essential for optimal immune system function

-Promotes calcium absorption

-Reduces of inflammation

-Modulates cell growth

-Supports healthy glucose metabolism

-Allows for optimal bone growth and development in children

-Protects against osteoporosis (thin and weak bone)

-Required for proper muscle function

-Imperative to nerve function (caring messages to the body from the brain)

– Essential in the process of genetic coding of proteins that regulate cell proliferation, differentiation, and apoptosis 

 Vitamin D synthesis, hydroxylations, and actions involve nearly every system in the body, and thus a deficiency will inevitably create extreme nutrient and mineral imbalances, creating vulnerability for disease to set in and wreak havoc.   

Given that vitamin D deficiency is linked to some of the important risk factors associated with the leading causes of death, it is imperative that the public is aware of this connection to avoid the detriments of deficiency with early intervention strategies. 

Who is most at risk for Vitamin D deficiency? 

The overall prevalence rate of vit D deficiency amongst adults in the U.S. is a startling 41%, with the highest rates seen in African-Americans (82%) and Hispanics (69%). 

The following populations have an increased risk of Vitamin D deficiency: 

-Breastfed infants

-Women who are pregnant 

-Older adults 

-People with limited daily skin exposure to sunshine

-Sunscreen users

-People with dark skin

-People with conditions that limit fat absorption (Such as Crohn’s disease, celiac disease, or ulcerative colitis)

-People who are obese

-People who have undergone gastric bypass surgery

-People with a poor health status

-People who have hypertension

-People with low high-density lipoprotein cholesterol (HDL) level

-People who do not consume fortified cow’s milk daily

-People who do not eat fish frequently  

-People with kidney or liver disease

-People with hyperparathyroidism

-People with chronic inflammatory diseases

-People taking medicines that affect vitamin D metabolism, such as cholestyramine (a cholesterol drug), anti-seizure drugs, glucocorticoids, antifungal drugs, and HIV/AIDS medicines.

What are common symptoms of Vitamin D deficiency? 

One of the most common symptoms of deficiency in an increased risk of illness and infections. Mounting evidence suggests that vitamin D deficiency could be linked to several chronic diseases, including cardiovascular disease, osteoporosis, and cancer. 

Other common symptoms of Vitamin D deficiency are: 


-Daytime headaches

-Frequently ill with colds, flu, and respiratory illnesses, such as bronchitis, and respiratory tract infections

-Increased susceptibility to bacterial infections 

– Unexplained aches and pains (muscular and joint)



-Slow wound healing


-Deformities in the teeth

-Developmental delays 


-Irritability and mood fluctuations
