How badly do our Health Ministers want to reduce Covid infections and deaths? Not much. If they were at all serious — before they hand out free vaccines, they’d hand out free Vitamin D supplements.

In a study conducted in a Galilee hospital, 26 percent of vitamin D-deficient coronavirus patients died, while among other patients the figure was at 3%.  — Times of Israel

If only black lives mattered?  Dark skins are so much more likely to be deficient, this is one of those absolutely easy wins for any politician, yet none of them are doing it?

Nearly half the people in the study were deficient, and half of those who were seriously deficient in Vitamin D would go on to develop a severe case. These were the people with levels below 20 ng/ml. Of all the people above that, only 10% would get a severe case. And just being “above 20ng” would still be classified as moderately deficient by many measures, yet it made such a huge difference.

It was a life and death thing — the mortality rate was 25%, fully five times higher for those who fell below the 20ng/ml bar.

The Israeli study looked at the Vitamin D levels of 1200 patients in their medical records before they got infected with Covid. This is important because although studies like the Indonesian study last year showed that people with low levels of Vitamin D were much more likely to die of Covid, those patients weren’t assessed until they turned up at hospital when  they were already sick. We couldn’t be sure that something about  Covid itself wasn’t chewing through the Vitamin D levels and causing the deficiency. So an Israeli team looked back through their records for up to 2 years to see what their last blood tests showed.

People with the lowest Vitamind D levels were the most likely to get severe Covid.

It’s a retrospective study, so the blood levels of D might have changed, yet despite that, the results still pop out of the data. Ideally we’d measure them just before they got sick.

Don’t wait til you’re in ICU to fix that deficiency. And definitely don’t wait for the CDC or Anthony Fauci to suggest it. 

The biggest disadvantage with Vitamin D is that there’s no money in  it.

As I’ve said before:

Vitamin D deficiency is so common it’s an epidemic affecting a billion people around the world.

Vitamin D levels also correlate with lower rates of cancer, diabetes, high blood pressureasthma, heart disease, dental caries, preeclampsia, autoimmune diseasedepressionanxiety, and sleep disorders. Vitamin D influences over 200 genes. It’s so crucial, it was likely the reason northern Europeans evolved whiter skin. The lack of sunlight and the introduction of grains in diets (as opposed to eating liver and whales) meant that Europeans weren’t getting enough D from either food or sun. The selective pressure was so strong that lighter skin rapidly took over all the northern communities. Eskimos didn’t need to go white — they were still getting D from offal and plenty of fish.


Results Of 1176 patients admitted, 253 had VitD levels prior to COVID-19 infection. Compared with mildly or moderately diseased patients, those with severe or critical COVID-19 disease were more likely to have pre-infection vitamin D deficiency of less than 20 ng/mL (OR=14.30, 95%, 4.01-50.9; p < .001); be older (OR=1.039 for each year, 95% CI for OR, 1.017-1.061; p< .01), and have diabetes (OR=2.031, 95% CI for OR, 1.04-3.36; p= 0.038). Vitamin D deficiency was associated with higher rates of mortality (p<0.001) and comorbidities.

Half of the people were severely deficient:

Of the 253 individuals with pre-infection VitD levels, 133 (52.5%) had a level less than 20 ng/mL, 36 (14.2%) had 20 to less than 30 ng/mL, 44 (17.3%) had 30 to less than 40 ng/mL, and 40 (15.8%) had 40 ng/mL or greater  (Table 1). Mortality among patients with sufficient VitD levels was 2.3%, in contrast to the VitD deficient  group’s 25.6% mortality rate (p-value<0.001).

Vitamin D is measured in two  different units:

Patients’ 25(OH)D levels were divided into four universally accepted categories: deficient (below 50 nmol/L or 20 ng/ml), insufficient (50 nmol/L to 75 nmol/L or 20 -29.9 ng/ml), adequate (75-99.75 nmol/L or 30-39.9 ng/ml), and high-normal (above 187.5 nmol/L or 40 ng/mL).
