Coronavirus and Vitamin D – Can low Vitamin D levels increase your risk?

About 1 billion people have low vitamin D levels worldwide according to the National Institute of Health [1]. A growing number of people have Vitamin D deficiency worldwide, but can low Vitamin D levels really increase your risk of Coronavirus? Lets see the link between Coronavirus and Vitamin D.


What Is Vitamin D & How Do We Get It?

Vitamin D is a fat-soluble vitamin, known as the “sunshine vitamin” as our bodies produce it when we’re exposed to direct sunlight – the primary natural source of Vitamin D as you probably know. One of the functions of our skin is to absorb it. It is important to note however, that excessive sun exposure can prematurely age and damage the skin too.

The sun makes us feel happy and healthy but as many people are in indoors in isolation at the moment, they’re not getting enough Vitamin D.

Vitamin D is extremely vital for the following reasons:

  • To help our bodies build Calcium and maintain healthy bones [2]
  • Regulates immune cells function [3]
  • Helps regulate the neuromuscular system
  • Plays a major role in the life cycle of human cell

Similar to Vitamin C, our bodies don’t produce Vitamin D by themselves so we need to either absorb it, or ingest through our diet. But there aren’t many high Vitamin D foods other than fatty fish, and even if you get enough sunlight, other factors can affect your vitamin D levels [4]. So the best way to try to ensure you get your daily dose is through dietary supplements.

It is recommended that adults get at least 1,000 to 2,000 IU per day of vitamin D as it can help people achieve an adequate blood level of vitamin D, and may have additional health benefits.

There are side effects of taking too much Vitamin D [5], although it is very rare. NHS [6] state taking more than 100 micrograms (4000 IU) could be harmful.

What Health Risks Does Low Vitamin D Cause?

[7] Vitamin D is so important that without it, our bones to become soft, misshapen, brittle, thin and fragile, which can cause them to break more easily as well as a number of other health problems including:

  • Muscle weakness
  • Increased risk of death from cardiovascular disease
  • Cognitive impairment in older adults
  • Severe asthma in children
  • Cancer
  • Osteoporosis
  • Osteomalacia
  • Increased risk of falls
  • Multiple sclerosis
  • Rheumatoid arthritis
  • Type 1 Diabetes
  • Systemic Lupus Erythematosus (SLE)
  • Psoriasis
  • Hypertension [8]

As insufficient Vitamin D is linked to respiratory conditions and the immune system, it is important to get your daily dose during lockdown.

What is the immune system again?

The immune system is our body’s defense system that fights off infections and viruses such as Coronavirus. That’s why it’s important to strengthen your immune system.

Research [9] shows that Vitamin D play a major role in protecting the lung from infection. That’s one of the reasons why people get more sick in the winter, because there’s less sunlight and less Vitamin D, causing more Vitamin D deficiency.

Bear in mind there is no proven evidence to support that Vitamin D supplements will prevent you from getting Coronavirus. It is just appears to be required for healthy immune system function, similar to Zinc and Vitamin C.

eVitamins have a massive range of vitamins and supplements available.

These are the ones I’d highly recommend.

Some people that are at an even higher risk of Vitamin D deficiency are:

  • Pregnant and breastfeeding women
  • Teenagers and young women

  • People who have low or no exposure to the sun e.g. those
    who cover their skin for cultural reasons or confined indoors
  • People who have darker skin as darker skin such as Africans, Asians and Hispanics as our skin contains more melanin which protects it from the sun’s UV rays
    and therefore doesn’t absorb as much sunlight
  • Those who follow a strict vegan diet as they don’t consume as many Vitamin D foods
  • Those with a past medical history of vitamin D deficiency
  • People with osteoporosis or osteopenia
  • Those who have Crohn’s disease or other reasons for fat malabsorption

What’s the difference between Vitamin D2 & D3?


Both Vitamin D2 and Vitamin D3 are absorbed into the blood stream but the liver metabolizes them differently.


The main difference between Vitamin D2 and Vitamin D3 is their source.

D2 comes from plant-based foods such as mushrooms, and fortified foods which means they have added vitamins and other supplements to increase the nutritional value.

D3 is the one that our skin produces and also found in animal sources such as oily fish, and smaller amounts in egg yolk, cheese and beef liver.


Vitamin D3 is the one that’s recommended by Experts. [12]

  1. Hi Sammi,

    Well that was certainly a fascinating read and a subject I can definitely relate to.

    As you’ve mentioned, there’s no direct evidence that there is a correlation between vitamin D deficiency and an increased risk of coronavirus, but I totally understand the effects that such a defiency can have on the both the mind and body.

    I recall a few years back I felt extreme rundown and displayed many of the symptoms you’ve mentioned, but choose to ignore it at first.

    Eventually I went to see my doctor and was diagnosed with a severe vitamin D deficiency.

    It amazed me that it could have such extreme consequences for both my physical and mental wellbeing.
