COVID-19 and Vitamin D

May 2020

If you’ve read my previous posts you know that I’ve been recommending Vitamin D and explaining why and how important Vitamin D is to your immune system. Now studies are starting to be published demonstrating that it’s literally the difference between life and death!

The first is a study from The University of Southeastern Philippines. They looked back at over 200 cases of Covid-19 with varying degrees of symptoms from mild to severe. All had their Vitamin D status checked on multiple occasions. The levels were categorized as normal >30 ng/ml, insufficient 20-29 ng/ml and deficient < 19 ng/ml. The results were as you might guess. Eighty-five percent of those with normal levels had mild symptoms, of those that were insufficient less than 2% had mild symptoms and nearly a third had severe symptoms and over 20% were critical. Ninety-eight percent (98%) of those that were below 29 ng/ml ended up with pneumonia or worse!

Another U.S. study done in New Orleans came to the same conclusion, those with Vitamin D levels below 30 ng/ml had the worst outcomes. They went on to say that Vitamin D insufficiency affects 80-90% of the African American population.

Another study found that, “When controlling for age, sex, and comorbidity, Vitamin D status is strongly associated with COVID-19 mortality.”

Researchers at Queen Elizabeth Hospital Foundation Trust and the University of East Anglia in England compared the average Vitamin D levels of 20 European countries with COVID-19 mortality rates — and found “significant relationships” between vitamin D levels and the number of deaths caused by this infection.

And from Colorado Dr. Erik Hermstad, MD reports that no patients were admitted to the hospital with Vitamin D levels above 40 ng/ml. From his twitter “we should be mass testing vitamin D levels. Those who are insufficient or deficient quarantine and treat until level is ~35. Those who have normal levels and no major risk factors return to activities with proper infection control practices. Check D and release.”

My recommendations are to get your blood levels of Vitamin D into an optimal range of 50 to 80 ng/ml. You will more than likely need to supplement with several thousand iu’s of Vitamin D daily. Personally, I use 5,000 in a sublingual form to enhance absorption. If you take it orally you should take it with the fattiest meal of the day. More is not better. I don’t recommend levels above 100.

Yours in good health,

Dr. Charles Hough
