Video Friday: Vitamin D and COVID 19: The Evidence for Prevention and Treatment of Coronavirus (SARS CoV 2)

It’s Video Friday! Today’s video is a bit longer than what we have previously shared, but it is definitely worth watching and sharing with anyone interested in vitamin D! It is an easy-to-follow, excellent review of the evidence supporting the importance of vitamin D for our health, especially during this COVID-19 pandemic.

In this video, Professor Roger Seheult, MD explains the role vitamin D may have in the prevention and treatment of COVID-19. It contains excellent illustrations on how vitamin D works, summarizes the best available data and clinical trials on vitamin D, respiratory diseases, and COVID-19, discusses vitamin D dosage recommendations, and more.

Please take a moment to watch and share the video along with our detailed information below.

Vitamin D – A Therapeutic Agent in the Fight Against COVID?

Here is a quick summary of what this video discusses, along with additional information and details about vitamin D:

Starting with Some Vitamin D Basics

Why is Vitamin D Deficiency an Issue?

  • Each individual can only produce enough vitamin D if getting enough sunlight or getting enough vitamin D from a dietary/supplement form
  • A majority of the population lacks sufficient sunlight/UVB exposure
  • See an excellent map of the United States showing who can and cannot make vitamin D in winter months (at 8:42)
  • Studies have repeatedly shown that less sunlight exposure correlates with an increased incidence of viral infections, such as the flu

Review of Vitamin D and Respiratory Tract Infections

  • Published research
  • Roles of vitamin D in the immune system, actions on our immune cells

Vitamin D levels – how to define deficiency, insufficiency, etc. (12:30)

Review of the Evidence of Vitamin D Deficiency (age, race, BMI, disagreement in supplementation amounts by ‘the experts’) (13:20)

Review of Evidence of Vitamin D and Respiratory Diseases Before COVID-19 (16:20)

Review of Vitamin D and COVID-19 Research (22:00)

  • Risk factors for COVID are similar to risk factors for vitamin D deficiency
  • Observational data shows a strong correlation between vitamin D deficiency and COVID-19 positivity, outcomes (when looking at vitamin D levels both before and at time of active infection)
  • Association vs Cause; a randomized controlled trial by Castillo et al. (41:05)
  • Bolus dose results (one dose of 200,000 IU at admission) showed no difference in outcomes – important to take vitamin D daily, weekly at very least (44:45)
  • Correlation between COVID-19 Severity, Inflammation, and Vitamin D Levels (47:15)

Conclusion: Must Take Vitamin D Seriously!

  • Review of food fortification, dietary intake, supplementation recommendations, etc.
  • The risk of vitamin D toxicity – Extremely Rare! (52:10)

The take home message? Vitamin D has been shown to have a significant effect on COVID-19 infection and outcomes, and taking vitamin D seriously (as in taking ACTION) is especially important during the winter when vitamin D levels tend to be lowest. Supplement and test make sure you’re not deficient!

What does the Research Say about Vitamin D & COVID-19?

It’s TIME to start saving lives! If you can help PREVENT the majority of the death, it’s time! What’s it costing you/us not to take action NOW?

There is much published research that supports a clear link between vitamin D and COVID-19 showing that higher vitamin D levels are related to:

a decreased risk of testing positive for COVID-19

increased viral SARS-CoV-2 RNA clearance

better clinical outcomes among patients with COVID-19

less severe COVID-19 disease

decreased risk of death due to COVID-19

Be sure to educate yourself on the benefits and importance of vitamin D for immune health, and take steps to ensure you and your loved ones are getting enough.
