Are you Getting Enough Vitamin D?

Millions of Canadians are not!

Vitamin D3 is central to better health in many ways. It helps supports immune function and lock down calcium for bone growth and tooth health.

Approximately 1/3 of Canadians are Vitamin D3 deficient, according to Statistics Canada.1 This number fluctuates seasonally with 40% of Canadians being deficient during winter months, and a surprisingly high 25% during summer.

Why sunshine is not sufficient

Summer’s soothing rays may feel great; however, exposure to adequate amounts sunshine to produce the required amount of daily Vitamin D3 is more difficult than one might think.

Vitamin D3 is produced by our body via sun exposure, with required amounts of ultraviolet radiation, on uncovered skin. However, in most Canadian cities, the sun is only strong enough between May and August. To produce adequate daily levels, you need to spend at least 20 minutes outdoors between 10 a.m. and 2 p.m., with most of your skin exposed, and without sun protection.

Factors that diminish Vitamin D production

  • avoiding harmful UV radiation altogether
  • using sunscreen
  • wearing UV-protective clothing
  • sun umbrellas / shade
  • working indoors (most windows block UV)
  • having darker skin tones (melanin blocks UV absorption)
  • pregnancy / peri-natal and breast feeding
  • smog
  • heavy cloud cover (UV rays can pass through light clouds)
  • aging
  • living in the northern hemisphere

Is all Vitamin D the same?

Nowadays most of the people know the ‘’sun vitamin“ but few are aware that there are significant differences between the two forms D2 and D3. Both are produced with the support of the sun UV’s yet Vitamin D2 is a plant vitamin that can be found in mushrooms and certain types of plaids, whereas Vitamin D3 is primarily produced in self-synthesis but is also found in fatty fish species and dairy products.


One thing they have in common: the human body must transform either form of Vitamin D for it to become active. Fortified foods and supplements can contain both forms, but studies show that Vitamin D3 has a greater impact on health. This is due to a more efficient metabolism: for instance, vitamin D3 binds better to the transport molecules in the blood, resulting in superior distribution throughout the body.

Vitamin D3, also called Cholecalciferol, should be the favoured form for fortified foods and supplements.

Effect of calcifediol treatment versus intensive care unit admission and mortality among patients hospitalized for COVID-19

Castillo M.E. et al demonstrated that calcifediol, significantly reduced the need for ICU treatment of patients requiring hospitalization due to proven COVID 19.


" Our pilot study demonstrated that administration of a high dose of Calcifediol or 25-hydroxyvitamin D, a main metabolite of vitamin D endocrine system, significantly reduced the need for ICU treatment of patients requiring hospitalization due to proven COVID-19. Calcifediol seems to be able to reduce severity of the disease, but larger trials with groups properly matched will be required to show a definitive answer. "

COVID-19 and vitamin D - Is there a link and a possibility of intervention?

In this letter to the editor, Jakovac (2020) recalls the existence of a large body of well-established data on the antiviral, immunomodulatory, and anti-inflammatory effects of vitamin D; which may prove useful against COVID-19, especially to combat symptoms of acute respiratory distress and cytokine storms.


" From the public health aspect, the recommendation of intensive supplementation as possible prophylaxis also could be considered. Given the good tolerability and safety of even high doses of vitamin D, this approach complies primum non nocere principle (first, do no harm). "

‘Scientific strabismus’ or two related pandemics: COVID-19 & vitamin D deficiency.

Kara and colleagues (2020) put the geography of COVID-19 in perspective in this article, observing that the countries most affected by the disease (countries of mid-northern latitude with an average temperature of 5 to 11 ° C and a low humidity), are also those where populations are most deficient in Vitamin D. For example: 40% of Europeans are deficient in vitamin D (25-hydroxyvitamin D (25OHD) <50 nmol / l) and 13% are deficient (25OHD <30 nmol / l).


" […] we would like to call attention to the possible association between severe vitamin D deficiency and mortality pertaining to COVID-19. Given its rare side effects and relatively wide safety, prophylactic vitamin D supplementation and/or food fortification might reasonably serve as a very convenient adjuvant therapy for these two worldwide public health problems alike.

Optimization of vitamin D status for enhanced immuno-protection against COVID-19.

McCartney and Byrne (2020) point out the link between vitamin D deficiency and the increased risks of respiratory infections; as well as certain protective mechanisms of vitamin D such as the suppression of CD26, a cell adhesion molecule used by SARS-Cov-2 for the invasion of host cells; or the attenuation of the inflammatory responses of gamma interferon (IFNγ) and interleukin 6 (IL-6), two strong predictors of poor results in critically ill patients on respiratory assistance, including those affected by Covid -19.


" We recommend that all older adults, hospital inpatients, nursing home residents and other vulnerable groups (e.g. those with diabetes mellitus or compromised immune function, those with darker skin, vegetarians and vegans, those who are overweight or obese, smokers and healthcare workers) be urgently supplemented with 20-50µg/d of vitamin D to enhance their resistance to Covid-19, and that this advice be quickly extended to the general adult population.

Vitamin D Supplementation to Prevent Acute Respiratory Tract Infections

In this systematic review and meta-analysis, Martineau and colleagues (2017) selected 25 randomized controlled trials including 11,321 participants aged 0 to 95 years, who took vitamin D as a supplement.


" Vitamin D supplementation was safe, and it protected against acute respiratory tract infection overall. Patients who were very vitamin D deficient and those not receiving bolus doses experienced the most benefit. "

Association of Vitamin D Deficiency and Treatment with COVID-19 Incidence

Low plasma 25(OH) vitamin D3 level is associated with increased risk of COVID-19 infection

Merzon E. and colleagues (2020) estimate that people deficient in vitamin D3 (25-OH-D3 <30ng / ml (<75 nmol / L)) are 58% more likely to be infected with SARS-cov- 2, and 109% more at risk of being hospitalized in case of infection. Psychiatric and somatic disorders, age over 50, low socio-economic status and being male were also associated with a higher risk of COVID-19.


" The mean plasma vitamin D level was significantly lower among those who tested positive than negative for COVID-19. "

Vitamin D deficiency and co-morbidities in COVID-19 patients - A fatal relationship?

Biesalski (2020) puts COVID-19 risk factors in perspective while looking at their close links with vitamin D status and the renin-angiotensin system - RAS (one of the most important endocrine and enzymatic regulation systems of autonomic, cardiovascular and pulmonary functions); including hypertension and cardio and cerebro-vascular diseases, diabetes, kidney disease or chronic obstructive pulmonary disease. The author also describes the role of vitamin D and the RAS in symptoms related to COVID-19 such as respiratory distress syndrome, cytokinic storm or Kawasaki syndrome.


" Co-morbidities and old age show a relationship with Renin-Angiotensin-Aldosteron-System (RAS), vitamin D status and COVID-19 infection. "
